[0002] In critical industries such as finance and energy, network environments typically employ network isolation technologies for physical isolation to ensure internal network security. Network isolation devices generally only allow application layer protocols such as Hypertext Transfer Protocol (HTTP) / Hypertext Transfer Protocol Secure (HTTPS) to pass through, while prohibiting transport layer protocols such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) from directly penetrating. However, instant messaging software often relies on persistent TCP connections to maintain real-time message communication, which presents a significant challenge in a network isolation environment. Summary of the Invention

[0028] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0030] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Based on this, embodiments of this application provide a message response method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the message response method of this application.

[0032] In this embodiment, the message response method includes the following steps: Step S10: Receive the transport layer protocol request sent by the client and convert the transport layer protocol request into an application layer protocol request.

[0033] It should be noted that the execution subject in this embodiment can be the first adapter, which can be an external network adapter, that is, an adapter deployed in the external network area, which can receive TCP connections from external network clients. The external network adapter corresponds to the internal network adapter.

[0034] Understandably, once the instant messaging software on the external network client is started, such as chat software or office software, the first adapter can establish a TCP long connection with the external network client, thereby being able to receive transport layer protocol requests sent by the external network client. The transport layer protocol request can be a TCP, UDP, or other request. The request header can include the connection identifier of the TCP long connection, and the request body can include business data sent by the user through the instant messaging software.

[0035] In practical implementation, transport layer protocols can be converted into application layer protocol requests, which can be HTTP / HTTPS requests, etc., thereby enabling the transport layer protocol requests to be encapsulated into a format that the gateway can transmit.

[0036] Step S20: Transmit the application layer protocol request to the second adapter so that the second adapter can provide an application layer protocol response based on the application layer protocol request. The first adapter and the second adapter are isolated by a network gateway.

[0037] Understandably, the second adapter can be an intranet adapter, i.e. an adapter deployed in the intranet area. The first and second adapters are physically isolated by a network gateway to ensure intranet security.

[0038] In a specific implementation, the application layer protocol request output by the first adapter can be transmitted to the second adapter through the network gateway. After receiving the application layer protocol request, the second adapter can send back the obtained application layer protocol response and transmit the application layer protocol response to the first adapter through the network gateway.

[0039] Step S30: Convert the application layer protocol response into a transport layer protocol response and send the transport layer protocol response to the client.

[0040] It should be understood that after the first adapter receives the application layer protocol response transmitted by the second adapter through the network gateway, the first adapter can convert the application layer protocol response into a transport layer protocol response and send the transport layer protocol response to the client through a TCP long connection. The client can then receive the transport layer protocol response obtained based on the transport layer protocol request.

[0041] In practical implementation, a protocol conversion engine can achieve bidirectional conversion between transport layer protocols and application layer protocols, including packet parsing, protocol encapsulation, and data format conversion. Protocol conversion maintains the characteristics of TCP long connections, avoiding the high latency issues caused by HTTP polling, reducing message transmission latency by more than 80%. No modifications to existing IM client and server code are required; protocol conversion is implemented through the adapter layer, resulting in simple deployment and low maintenance costs.

[0042] In this embodiment, all data is transmitted via HTTP, complying with the gateway's security policy, and supports HTTPS encryption to ensure data transmission security. It supports both TCP and HTTP protocol penetration, and can simultaneously handle IM message communication and business interface calls, meeting the needs of complex business scenarios.

[0043] This embodiment receives transport layer protocol requests sent by the client, converts them into application layer protocol requests, and then transmits the application layer protocol requests to the second adapter. The second adapter then sends an application layer protocol response based on the application layer protocol request. The first and second adapters are isolated by a network gateway. The application layer protocol response is then converted back into a transport layer protocol response and sent to the client. In this embodiment, the first adapter receives transport layer protocol requests sent by instant messaging software on the client based on an established TCP long connection, converts the transport layer protocol requests into application layer protocol requests, and then transmits the application layer protocol requests to the second adapter through the network gateway. The second adapter sends an application layer protocol response based on the application layer protocol request through the network gateway, converts the application layer protocol response back into a transport layer protocol response, and returns it to the client through the established TCP long connection. This allows the instant messaging software to establish a TCP long connection in a network gateway-isolated environment, achieving real-time, reliable, and efficient message communication.

[0044] refer to Figure 2 , Figure 2 This is a flowchart illustrating the second embodiment of the message response method of this application.

[0045] Based on the first embodiment described above, in this embodiment, step S10 includes: Step S101: Receive the transport layer protocol request sent by the client, and extract transport layer data from the transport layer protocol request.

[0046] Understandably, after the first adapter receives the transport layer protocol request sent by the client, it can strip the protocol control information, such as the information stored in the request header, from the transport layer protocol request and retain only the pure business data as transport layer data for subsequent processing.

[0047] Step S102: Parse the transport layer data and generate identification information based on the obtained parsing information.

[0048] It should be understood that transport layer data can be parsed, and identification information can be generated based on the parsed information. The identification information can represent the identifier corresponding to the transport layer protocol request.

[0049] Furthermore, in order to effectively generate identification information, in this embodiment, step S102 includes: parsing the transport layer data to obtain parsed information; extracting key fields from the parsed information and generating a first command identifier based on the key fields; generating a first sequence number using the snowflake algorithm and determining the identification information based on the first sequence number and the first command identifier.

[0050] Understandably, the first adapter can parse the extracted raw byte stream data, i.e., transport layer data, and parse it into structured data that the program can understand, i.e. parsed information, such as an object or a dictionary, according to the application layer protocol agreed upon in advance between the client and the first adapter, thus completing the conversion from incomprehensible bytes to processable information.

[0051] It should be understood that key fields can be extracted from the parsed information to obtain specific fields that represent the business type, such as cmd, action, and type. These fields are then mapped and converted into an internally unified command identifier; for example, the first command identifier corresponding to the cmd field is 2. Simultaneously, the snowflake algorithm can be used to independently generate a globally unique numerical ID for the transport layer protocol request as the first sequence number. The first sequence number (seq) serves as the identification number for the transport layer protocol request, used for accurate matching of requests and responses, end-to-end log tracking, and preventing message replay. The first command identifier (cmd) serves as the business label for the transport layer protocol request, telling the system how to process it. Finally, the first sequence number and the first command identifier are used together as identification information.

[0052] Step S103: Convert the transport layer protocol request into an application layer protocol request based on the identification information.

[0053] Understandably, a transport layer protocol request can be converted into an application layer protocol request based on identification information, and the request header of the application layer protocol request can store identification information.

[0054] Furthermore, in order to effectively construct the application layer protocol request, in this embodiment, step S103 includes: obtaining a first connection identifier number for establishing a first transport layer protocol connection with the client; storing the first sequence number, the first command identifier, and the first connection identifier number in the application layer protocol header field, and storing the transport layer data in the application layer protocol message body; and constructing the application layer protocol request based on the application layer protocol header field and the application layer protocol message body.

[0055] It should be understood that after the external client starts, it can request the TCP connection port from the login center. The login center can return the TCP port that the first adapter is listening on to the client. The client can establish a long TCP connection with the first adapter through the TCP port. The first adapter assigns a unique connection ID, i.e., the first connection identifier, to each first transport layer protocol connection.

[0056] Understandably, the first sequence number, the first command identifier, and the first connection identifier can be stored in the application layer protocol header field, i.e., the request header; and the transport layer data can be stored in the application layer protocol message body, i.e., the request body; and then the application layer protocol request can be constructed based on the application layer protocol header field and the application layer protocol message body.

[0057] This embodiment receives a transport layer protocol request sent by a client, extracts transport layer data from the request, parses the transport layer data, generates identification information based on the parsed information, and then converts the transport layer protocol request into an application layer protocol request based on the identification information. This embodiment extracts transport layer data from the transport layer protocol request and generates identification information based on the parsed information, enabling the converted application layer protocol request to carry the identification information for subsequent TCP connection tracking.

[0058] refer to Figure 3 , Figure 3 This is a flowchart illustrating the third embodiment of the message response method of this application.

[0059] Based on the above embodiments, in this embodiment, step S30 includes: Step S301: Extract the second connection identifier from the response header of the application layer protocol response.

[0060] Understandably, after the first adapter receives the application layer protocol response returned by the second adapter through the network gateway, it can extract the second connection identifier from the response header of the application layer protocol response. The second connection identifier can be consistent with the connection identifier requested by the transport layer protocol corresponding to the application layer protocol response.

[0061] Step S302: Search for the second transport layer protocol connection corresponding to the second connection identifier in the first preset mapping table.

[0062] It should be understood that the first preset mapping table can be a pre-set mapping relationship between TCP connection ID and TCP connection, that is, the mapping relationship between connection identifier and transport layer protocol connection. Therefore, the second transport layer protocol connection corresponding to the second connection identifier can be found from the first preset mapping table.

[0063] Step S303: Convert the application layer protocol response into a transport layer protocol response, and send the transport layer protocol response to the client through the second transport layer protocol connection.

[0064] In a specific implementation, the first adapter can convert the application layer protocol response into a transport layer protocol response, and send the transport layer response to the corresponding client through the second transport layer protocol connection. The transport layer protocol request and the transport layer protocol response are transmitted through the same TCP connection.

[0065] Further, in this embodiment, step S303 includes: extracting a second sequence number and a second command identifier from the response header of the application layer protocol response; matching the second sequence number and the second command identifier with the second transport layer protocol connection to obtain a target transport layer protocol connection that has passed the match; converting the application layer protocol response into a transport layer protocol response, and sending the transport layer protocol response to the client through the target transport layer protocol connection.

[0066] Understandably, after obtaining the second transport layer protocol connection corresponding to the second connection identifier, multiple requests may be waiting for a response on the same transport layer protocol connection simultaneously. In this case, the second sequence number and the second command identifier can be extracted from the response header of the application layer protocol response. Then, the second sequence number and the second command identifier are matched with the second transport layer protocol connection to obtain the target transport layer protocol connection that has passed the match. The sequence number in the response header of the transport layer protocol response corresponding to the target transport layer protocol connection is the aforementioned second sequence number, and the command identifier is the aforementioned second command identifier.

[0067] In a practical implementation, the application layer protocol response can be converted into a transport layer protocol response, and then the transport layer protocol response can be sent to the client through the target transport layer protocol connection.

[0068] Further, in this embodiment, step S20 includes: transmitting the application layer protocol request to the second adapter; if no application layer protocol response based on the application layer protocol request is received from the second adapter within a preset time period, then returning to transmitting the application layer protocol request to the second adapter, and determining the current number of retries, until the new number of retries is less than the preset number and an application layer protocol response based on the application layer protocol request is received from the second adapter within a preset time period.

[0069] It should be understood that this embodiment may employ a timeout retransmission mechanism. If the application layer protocol response is not received from the second adapter within a preset time after the first adapter transmits the application layer protocol request to the second adapter, the timeout retransmission mechanism needs to be enabled. At this time, the first adapter may retransmit the application layer protocol request to the second adapter and determine the current number of retries. The number of retries may be the number of times the application layer request is retransmitted to the second adapter.

[0070] In the specific implementation, if the new number of retries is less than the preset number and an application layer protocol response is received from the second adapter within the preset time, it indicates that the retransmission was successful after the timeout; if the new number of retries is greater than or equal to the preset number, it indicates that the transmission was abandoned after multiple timeouts. The preset number of retries and the preset time can be dynamically adjusted according to the network status.

[0071] This embodiment extracts the second connection identifier from the response header of the application layer protocol response, then searches for the corresponding second transport layer protocol connection in a first preset mapping table, converts the application layer protocol response into a transport layer protocol response, and sends the transport layer protocol response to the client through the established second transport layer protocol connection. In this embodiment, the second connection identifier is first extracted from the response header of the application layer protocol response, and then the corresponding second transport layer protocol connection is found based on the second connection identifier, thus enabling the transport layer protocol response to be sent to the client through the established second transport layer protocol connection.

[0072] This application also provides a message response method, as described in the embodiments below. Figure 4 , Figure 4 This is a flowchart illustrating the fourth embodiment of the message response method of this application.

[0073] In this embodiment, the message response method includes the following steps: Step S40: Receive the application layer protocol request sent by the first adapter and convert the application layer protocol request into a transport layer protocol request.

[0074] It should be noted that the execution entity in this embodiment can be a second adapter, which can be an intranet adapter, i.e., an adapter deployed in the intranet area.

[0075] Understandably, the second adapter can receive application layer protocol requests sent by the first adapter through the network gateway and convert the application layer protocol requests into transport layer protocol requests.

[0076] Step S50: Send the transport layer protocol request to the service server so that the service server can respond with a transport layer protocol response based on the transport layer protocol request.

[0077] It should be understood that transport layer protocol requests can be sent to the intranet business server via a TCP connection, and the intranet business server can process the transport layer protocol requests and return transport layer protocol responses.

[0078] Step S60: Convert the transport layer protocol response into an application layer protocol response, and transmit the application layer protocol response to the first adapter.

[0079] In a specific implementation, the second adapter can convert the transport layer protocol response into an application layer protocol response and transmit the application layer protocol response to the first adapter through a network gateway.

[0080] In this embodiment, the external network adapter includes a TCP server: listening on a specified port, receiving TCP connection requests from external network clients, and maintaining a connection pool; an HTTP client: converting TCP packets into HTTP requests, supporting functions such as timeout retry and connection reuse; a protocol converter: implementing the conversion of TCP packets into HTTP requests, including data serialization, compression, encryption, and other processing; an ACK manager: maintaining a queue of pending acknowledgment packets and handling timeout retransmission logic; and a connection mapping table: storing the mapping relationship between TCP connection IDs and HTTP sessions. The internal network adapter includes an HTTP server: receiving HTTP requests sent by the external network adapter and parsing request parameters; a TCP client: maintaining a TCP connection pool with the internal network business server and supporting connection reuse; a protocol converter: implementing the conversion of HTTP requests into TCP packets, including data deserialization, decompression, decryption, and other processing; a multi-packet processor: handling multi-packet response scenarios, caching and merging packets sequentially; and a response generator: converting TCP responses into HTTP responses and supporting streaming transmission.

[0081] In this embodiment, an application layer protocol request is received from a first adapter and converted into a transport layer protocol request. The transport layer protocol request is then sent to a service server, which responds with a transport layer protocol response based on the request. This response is then converted into an application layer protocol response and transmitted back to the first adapter. Alternatively, a second adapter receives the application layer protocol request from the first adapter, converts it into a transport layer protocol request, and sends it to the service server via a TCP connection. The service server returns a transport layer protocol response based on the request, which is then converted back into an application layer protocol response by the second adapter and transmitted to the first adapter via a network gateway.

[0082] refer to Figure 5 , Figure 5 This is a flowchart illustrating the fifth embodiment of the message response method of this application.

[0083] Based on the fourth embodiment described above, in this embodiment, step S50 includes: Step S501: Extract the third connection identifier from the request header of the application layer protocol request.

[0084] Understandably, after the second adapter receives the application layer protocol request sent by the first adapter, it can extract the TCP connection ID, i.e., the third connection identifier, from the request header of the application layer protocol request.

[0085] Step S502: Determine the third transport layer protocol connection corresponding to the third connection identifier.

[0086] Furthermore, in order to effectively locate the third transport layer protocol connection corresponding to the third connection identifier, in this embodiment, step S502 includes: searching for the initial transport layer protocol connection corresponding to the third connection identifier from the second preset mapping table; if the initial transport layer protocol connection is valid, then using the initial transport layer protocol connection as the third transport layer protocol connection; if the initial transport layer protocol connection is invalid, then establishing a third transport layer protocol connection with the service server.

[0087] It should be understood that the second preset mapping table may include a pre-set mapping relationship between TCP connection IDs and TCP connections, so the initial transport layer protocol connection corresponding to the third connection identifier can be found from the second preset mapping table.

[0088] Understandably, it's possible to determine whether the initial transport layer protocol (TLP) connection is valid, specifically whether an initial TLP connection exists. If the initial TLP connection is valid, it's directly used as the third TLP connection; if the initial TLP connection is invalid, a new third TLP connection is established on the internal network service server.

[0089] Step S503: Send the transport layer protocol request to the service server through the third transport layer protocol connection, so that the service server can send back a transport layer protocol response based on the transport layer protocol request.

[0090] In a practical implementation, a transport layer protocol request can be sent to the business server via a third transport layer protocol connection, and the business server can return a transport layer protocol response based on the transport layer protocol request.

[0091] Further, in this embodiment, step S60 includes: Step S601: Determine whether the transport layer protocol response is a single packet response.

[0092] Understandably, after the second adapter receives the transport layer protocol response returned by the intranet service server, it can determine whether the transport layer protocol response is a single packet response.

[0093] Step S602: If yes, the transport layer protocol response is converted into an application layer protocol response, and the application layer protocol response is transmitted to the first adapter.

[0094] It should be understood that if the transport layer protocol response is a single packet response, the transport layer protocol response can be directly converted into an application layer protocol response and transmitted to the first adapter.

[0095] Step S603: If not, convert the transport layer protocol response into an application layer protocol response according to the response order of the transport layer protocol responses, and transmit the application layer protocol response to the first adapter.

[0096] Understandably, if the transport layer protocol response is not a single packet response, but a multi-packet response, the data packets can be buffered according to the response order of the transport layer protocol responses until all packets are received, and then merged into a complete application layer protocol response, and the application layer protocol response is transmitted to the first adapter.

[0097] Furthermore, in order to convert multi-packet responses into application layer protocol responses, in this embodiment, the step of converting the transport layer protocol responses into application layer protocol responses according to the response order of the transport layer protocol responses includes: extracting a third sequence number and a third command identifier from the response header of the transport layer protocol responses; matching the transport layer protocol responses based on the third sequence number and the third command identifier to obtain a matching result; merging the transport layer protocol responses based on the matching result and the response order of the transport layer protocol responses to obtain a merged transport layer protocol response; and converting the merged transport layer protocol response into an application layer protocol response.

[0098] It should be understood that the third sequence number and third command identifier can be extracted from the response header of the transport layer protocol response, and then the transport layer protocol response can be matched based on the third sequence number and third command identifier to obtain the matching result. The matching result can indicate which transport layer protocol request each transport layer protocol response is a reply to.

[0099] Understandably, since the business server may split a large response into multiple TCP packets for sending, the transport layer protocol responses corresponding to the same transport layer protocol request can be grouped into the same group. The second adapter can merge the transport layer protocol responses in the same group according to the response order of the transport layer protocol responses, that is, the order in which the data packets are received, to obtain the merged transport layer protocol response, and then convert the merged transport layer protocol response into the application layer protocol response.

[0100] In practice, it can monitor TCP connection status, data transmission success rate, latency and other indicators in real time, and automatically rebuild the connection and restore data transmission when the connection is abnormal.

[0101] In this embodiment, refer to Figure 6 , Figure 6 This is a schematic diagram of the overall architecture of an embodiment of the message response method of this application, as shown below. Figure 6As shown, the Client is an external network client. After the client's instant messaging software starts, it can obtain a TCP connection port from the login center of the Nginx service on the external network server. The Nginx service is a proxy static resource service. The client can then connect to the Adapter service on the external network server through the obtained TCP connection port. Adapter-server represents the external network adapter. The external network adapter can convert TCP data into HTTP requests and forward them to the Adapter service on the internal network server through the network gateway. Adapter-server represents the internal network adapter. The internal network adapter can obtain HTTP requests, convert them into TCP data, send them to Mobiled (the internal network business server), and return TCP packets. The internal network adapter converts the TCP data into HTTP requests and forwards them to the external network adapter. The external network adapter then returns TCP packets to the client. For static resources such as static web pages requested by the client, the Nginx service on the external network server can connect to the Nginx service on the internal network server and return the TCP port that the Adapter service is listening on. Then, the external Nginx service returns the request result of the Nginx proxy service to the client.

[0102] In this embodiment, refer to Figure 7 , Figure 7 This is an information flow diagram of one embodiment of the message response method of this application, such as... Figure 7 As shown, the external TCP proxy (TCP proxy): converts the TCP protocol to the HTTP protocol from the outside to the inside, routes it to the internal TCP proxy via the bus, and then converts the HTTP protocol back to the TCP protocol to interact with the internal TCP gateway; similarly, it performs the same operation when going from the inside to the outside to ensure normal TCP communication; the external HTTP proxy: when going from the outside to the inside, it proxies the Android mobile client's HTTP interface, converts the HTTP request according to the bus requirements, and after passing through the bus, it proxies it to the internal HTTP proxy, which converts the bus request back to the original request and interacts with the internal HTTP gateway; the external NGINX: static resources; requests cannot exceed 6 seconds, scheduled tasks cannot be written, the bus does not support TCP long connections, in case of a large number of abnormal requests, the bus will block registration information, the default HTTP method, the bus only supports POST requests, and the URL cannot contain parameters.

[0103] This embodiment extracts the third connection identifier from the request header of the application layer protocol request, then determines the third transport layer protocol connection corresponding to the third connection identifier, and sends the transport layer protocol request to the service server through the third transport layer protocol connection. The service server then responds with a transport layer protocol response based on the transport layer protocol request. It then determines whether the transport layer protocol response is a single-packet response. If so, the transport layer protocol response is converted into an application layer protocol response and transmitted to the first adapter. If not, the transport layer protocol responses are converted into application layer protocol responses according to the response order and transmitted to the first adapter. Alternatively, this embodiment uses a second adapter to send the transport layer protocol request to the service server through the third transport layer protocol connection, causing the service server to respond with a transport layer protocol response. It then determines whether the response is a single-packet response and converts it into an application layer protocol response based on the determination result. This approach can handle both single-packet and multi-packet response scenarios. The resulting application layer protocol response is then transmitted to the first adapter through a network gateway.

[0104] Reference Figure 8 , Figure 8 This is a structural block diagram of the first embodiment of the message response device of this application.

The first request transmission module 20 is used to transmit the application layer protocol request to the second adapter, so that the second adapter can feed back the application layer protocol response based on the application layer protocol request. The first adapter and the second adapter are isolated by a network gateway. The first response conversion module 30 is used to convert the application layer protocol response into a transport layer protocol response and send the transport layer protocol response to the client.

[0106] This embodiment receives transport layer protocol requests sent by the client, converts them into application layer protocol requests, and then transmits the application layer protocol requests to the second adapter. The second adapter then sends an application layer protocol response based on the application layer protocol request. The first and second adapters are isolated by a network gateway. The application layer protocol response is then converted back into a transport layer protocol response and sent to the client. In this embodiment, the first adapter receives transport layer protocol requests sent by instant messaging software on the client based on an established TCP long connection, converts the transport layer protocol requests into application layer protocol requests, and then transmits the application layer protocol requests to the second adapter through the network gateway. The second adapter sends an application layer protocol response based on the application layer protocol request through the network gateway, converts the application layer protocol response back into a transport layer protocol response, and returns it to the client through the established TCP long connection. This allows the instant messaging software to establish a TCP long connection in a network gateway-isolated environment, achieving real-time, reliable, and efficient message communication.

[0119] In this embodiment, an application layer protocol request is received from a first adapter and converted into a transport layer protocol request. The transport layer protocol request is then sent to a service server, which responds with a transport layer protocol response based on the request. This response is then converted into an application layer protocol response and transmitted back to the first adapter. Alternatively, a second adapter receives the application layer protocol request from the first adapter, converts it into a transport layer protocol request, and sends it to the service server via a TCP connection. The service server returns a transport layer protocol response based on the request, which is then converted back into an application layer protocol response by the second adapter and transmitted to the first adapter via a network gateway.
