DETAILED DESCRIPTION

[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0034] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use, processing, transmission, provision, disclosure and application of the relevant data comply with the relevant laws, regulations and standards of the relevant countries and regions, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0035] It should be noted that the remote link establishment method, device, electronic device, medium and product of the present application can be used in the field of cloud service technology, and can also be used in any field other than cloud service. The application field of the remote link establishment method, device, electronic device, medium and product of the present application is not limited.

[0036] Figure 1 A schematic diagram of an application scenario of a method for establishing a remote link provided in an embodiment of the present application is given by way of example in combination with the illustrated scenario: a remote link is established between a user terminal and a server, and data transmission between the user terminal and the server is achieved through the remote link.

[0037] In actual applications, link establishment is based on link information, which includes environment variables or temporary variables. If the link is disconnected, the link information will be lost. To reestablish the link, the link information needs to be reconfigured, resulting in low efficiency. The link also includes historical operation records. If the link is disconnected, the historical operation records will be lost, affecting the user experience.

[0038] The method for establishing a remote link provided in this application is intended to solve the above technical problems in the prior art.

[0039] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0040] Figure 2 A flowchart of a method for establishing a remote link provided in an embodiment of the present application, the method comprising the following steps:

[0041] S201: Receive a link establishment request sent by a user terminal.

[0042] The link establishment request includes a target user identifier.

[0043] Exemplarily, the user identification may be a unique identification of the user logging into the client. The user identification is used as the unique identification of the link corresponding to the link request.

[0044] Combined with the scenario example, the user ID can accurately determine the unique corresponding link to avoid link confusion.

[0045] S202: Establish a target communication protocol link between the middleware and the client according to the link establishment request.

[0046] The target communication protocol link may be a Web Socket protocol link. The Web Socket protocol link is a protocol for full-duplex communication over a single TCP link. It allows real-time, bidirectional data transmission between a user terminal and a server without the need for an HTTP request-response model.

[0047] Combined with the scenario example, real-time, low-latency two-way communication can be achieved through the Web Socket protocol link, thereby improving the user experience.

[0048] Optionally, the middleware is controlled by the server's program to perform work.

[0049] Combined with the scenario example, middleware has functions such as executing commands and storing. Middleware can establish links and store links and information. The links and information stored by the middleware can be reused, thereby improving the efficiency of establishing links.

[0050] S203: Determine a target security protocol link according to the target user identifier and the cache.

[0051] Among them, the target security protocol link is the link between the middleware and the server.

[0052] The target security protocol link may be a secure shell (SSH) protocol link. The SSH protocol link is used to remotely log in securely, execute commands, and transmit data. The SSH protocol provides strong security and reliability and is widely used in system management and remote operations.

[0053] Combined with the scenario example, the SSH protocol link can improve the security between the middleware and the server, thereby improving the security of the cloud service.

[0054] Exemplarily, the cache may store link information or historical operation records. The stored link information may be used to reduce the operation of configuration variables when establishing a secure protocol link. The stored historical operation records may be used to quickly restore historical sessions after the secure protocol link is reestablished, thereby avoiding the need for users to re-execute previous commands or operations and improving the user experience.

[0055] Optionally, the context information is stored in the cache. When the user switches devices or logs in again, the context information can be used to continue the previous operation and maintain a consistent user experience.

[0056] S204: Associating the target communication protocol link with the target security protocol link to establish a remote link between the client and the server.

[0057] Combined with the scenario example, the target communication protocol link is the link between the middleware and the user end, and the target security protocol link is the link between the middleware and the server. The target communication protocol link and the target security protocol link are independent of each other. Through association processing, the target communication protocol link and the target security protocol link work together to improve the efficiency of data transmission.

[0058] Specifically, the target communication protocol link has high stability and is not easy to disconnect. The links or link information stored in the middleware can be reused to improve the efficiency of establishing the target security protocol link. The target communication protocol link and the target security protocol link work together to cope with network failures or user misoperation, thereby improving the efficiency of data transmission.

[0059] The method for establishing a remote link provided in an embodiment of the present application receives a link establishment request sent by a user end, the link establishment request includes a target user identifier; according to the link establishment request, a target communication protocol link is established between the middleware and the user end; according to the target user identifier and the cache, a target security protocol link is determined, the target security protocol link is a link between the middleware and the server; the target communication protocol link is associated with the target security protocol link to establish a remote link between the user end and the server. The above scheme manages the link through the middleware, and can reuse the existing security protocol link to avoid frequent link establishment, thereby improving the efficiency of data transmission.

[0060] Based on any of the above embodiments, Figure 3 , the detailed process of establishing a remote link is explained.

[0061] Figure 3 A flowchart of a method for establishing a remote link provided in an embodiment of the present application. Figure 3 As shown, the method includes:

[0062] S301: Receive a link establishment request sent by a user terminal.

[0063] It should be noted that the execution process of S301 refers to S201 and will not be repeated here.

[0064] S302: Establish a target communication protocol link between the middleware and the client according to the link establishment request.

[0065] It should be noted that the execution process of S302 refers to S202 and will not be repeated here.

[0066] S303: Determine multiple historical link information stored in the cache and multiple corresponding historical user identifiers.

[0067] The plurality of historical link information are historical link information corresponding to historical links established in history, and the plurality of historical user information are user identifiers included in historical link establishment requests received in history.

[0068] Exemplarily, each time a link establishment request is received or a secure protocol link is established, the information stored in the cache is updated.

[0069] Combined with the scenario example, the data in the cache can be accessed immediately without reading from the database or other slow storage, which greatly shortens the response time. Through caching, network latency and disk I / O operations can be significantly reduced, improving the overall performance of the system.

[0070] If the target user identifier is included in the multiple historical user identifiers, S304 is executed.

[0071] If the target user identifier is not included in the multiple historical user identifiers, execute S305.

[0072] S304: Determine a target security protocol link according to the target user identifier, or establish a target security protocol link according to historical link information corresponding to the target user identifier.

[0073] Combined with the scenario example, if the target user identifier is included in the multiple historical user identifiers, it means that the target security protocol link corresponding to the target communication protocol link has been established. Examples are given for whether the target security protocol is disconnected.

[0074] As an example, for the scenario where the target security protocol link is not disconnected, the target communication protocol link and the target security protocol link both exist, but the target communication protocol link and the target security protocol link are not associated. The target security protocol link can be determined by the target user identifier and the corresponding relationship between the identifier and the link.

[0075] As another example, in the scenario where the target security protocol link is disconnected, the target communication protocol link exists at this time. If the association process is performed, the target security protocol link needs to be established first. The historical link information includes the link information of the target security protocol link that has been established. By reusing the historical link information, the target security protocol link can be quickly established.

[0076] S305: Establish a target security protocol link, determine target link information corresponding to the target security protocol link, and store the target link information into a cache.

[0077] In combination with the scenario example, if the target user identifier is not included in the multiple historical user identifiers, it means that the target security protocol link corresponding to the target communication protocol link has not been established, and the target security protocol link needs to be established.

[0078] Next, combine Figure 4 Describes how to determine the target security protocol link.

[0079] Figure 4 A schematic diagram of determining a target security protocol link provided in an embodiment of the present application. Figure 4 As shown, multiple historical user identifiers are determined from the cache. If the multiple historical user identifiers include the target user identifier, the target security protocol link can be determined from the existing security protocol links, or the target security protocol link can be established by reusing the historical link information. If the multiple historical user identifiers do not include the target user identifier, a new target security protocol link is established.

[0080] Exemplarily, if a new target security protocol link is established, the target link information corresponding to the target security protocol link is stored in the cache so that when the subsequent target security protocol link is disconnected and re-established, the target link information can be reused to quickly establish the target security protocol link.

[0081] S306: Determine whether there is a target association relationship in the cache.

[0082] The target association relationship is the association relationship between the target communication protocol link and the target security protocol link.

[0083] Exemplarily, the target association relationship corresponds one-to-one with the target communication protocol link and the target security protocol link.

[0084] If yes, execute S307.

[0085] If not, execute S308.

[0086] S307: Associating the target communication protocol link with the target security protocol link according to the target association relationship.

[0087] For example, if a target association relationship exists in the cache, it can be quickly determined through the target association relationship that the target communication protocol link and the target security protocol link can be associated and processed, thereby improving the efficiency of the association processing.

[0088] Exemplarily, after the association process is completed, data can be transmitted between the target communication protocol link and the target safety protocol link, that is, data is output from the target communication protocol link to the target safety protocol link, or data is output from the target safety protocol link to the target communication protocol link.

[0089] Optionally, the target association relationship includes an association processing method, and the target communication protocol link and the target security protocol link can be accurately associated with each other under the guidance of the association processing method.

[0090] S308, associating the input stream of the target communication protocol link with the output stream of the target security protocol link, associating the input stream of the target security protocol link with the output stream of the target communication protocol link, generating a target association relationship, and storing the target association relationship in a cache.

[0091] Combined with the scenario example, if there is no target association relationship in the cache, it means that the target communication protocol link and the target security protocol link have not been associated, and there is no guidance on the method of association processing.

[0092] As an example, after associating the input stream of the target communication protocol link with the output stream of the target security protocol link, when the user enters data in the user terminal and sends it to the middleware through the target communication protocol link, the middleware will forward the data to the target security protocol link, and then transmit it to the server to realize uplink data transmission.

[0093] As another example, after associating the input stream of the target security protocol link with the output stream of the target communication protocol link, when the server inputs data and sends it to the middleware through the target security protocol link, the middleware will forward the data to the target communication protocol link, and then transmit it to the user end, realizing downlink data transmission.

[0094] Combined with the scenario example, by generating and storing the target association relationship, the association processing can be accurately implemented in the subsequent process, thereby improving the accuracy of establishing the remote link.

[0095] A feasible implementation method, the method for establishing a remote link also includes: receiving target uplink data through a target communication protocol link; determining a target timestamp of a target security protocol link; determining a data type of the target uplink data, the data type including a heartbeat message or a non-heartbeat message; if the data type is a heartbeat message, updating the target timestamp according to the current time; if the data type is a non-heartbeat message, sending the target uplink data to a server through a target security protocol link, and updating the target timestamp according to the current time.

[0096] The target timestamp indicates the active state of the target security protocol link. The target timestamp is updated each time the target security protocol link works. The time corresponding to the target timestamp is the time when the target security protocol link was last active.

[0097] Among them, the heartbeat information is used to detect the active state of the link or the network status, so as to keep the target security protocol link alive and avoid the target security protocol link being automatically disconnected due to unused. Non-heartbeat messages are data that the user end needs to send to the server.

[0098] Next, combine Figure 5 Describe the update timestamp.

[0099] Figure 5 A schematic diagram of updating timestamps provided in an embodiment of the present application. Figure 5 As shown, the target uplink data sent by the user end is received through the target communication protocol link. The target timestamp of the target security protocol link is determined. If the target uplink data is heartbeat information, the target timestamp is updated only according to the current time. If the target uplink data is non-heartbeat information, the target uplink data is sent to the server through the target security protocol link, and the target timestamp is updated according to the current time.

[0100] In this feasible implementation, updating the target timestamp can reflect that the target security protocol link is in a normal working state at the current moment, thereby accurately indicating that subsequent data transmission is performed through the target security protocol link.

[0101] In a feasible implementation, the remote link establishment method further includes: receiving target downlink data through a target security protocol link; sending the target downlink data to the user end through a target communication protocol link, and updating the target timestamp according to the current time.

[0102] Combined with the scenario example, for the scenario where the server sends the target downlink data to the user end, the server sends the target downlink data to the middleware through the target security protocol link. The middleware forwards the target downlink data to the user end through the target communication protocol link. When the middleware forwards the target downlink data, it updates the target timestamp.

[0103] In this feasible implementation, updating the target timestamp during the transmission of downlink data can reflect that the target security protocol link is in a normal working state at the current moment, thereby accurately indicating subsequent data transmission through the target security protocol link.

[0104] A feasible implementation method, the remote link establishment method also includes: determining multiple historical timestamps stored in the cache, the multiple historical timestamps correspond one-to-one to multiple historical security protocol links, and the multiple historical timestamps correspond one-to-one to multiple historical link information; determining the link information to be cleaned from the multiple historical link information based on the multiple historical timestamps, and the time length between the historical timestamp corresponding to the link information to be cleaned and the current moment is greater than the time length threshold; deleting the link information to be cleaned from the cache; determining the security protocol link to be cleaned from the multiple historical security protocol links based on the multiple historical timestamps, and the time length between the historical timestamp corresponding to the security protocol link to be cleaned and the current moment is greater than the time length threshold; and disconnecting the security protocol link to be cleaned.

[0105] For example, if the duration threshold is 30 minutes, if the duration between the historical timestamp and the current time is greater than 30 minutes, it means that the corresponding historical security protocol link or historical link information has not been used for a long time, and the user's demand for the corresponding historical security protocol link or historical link information is not high, and cleaning it up can effectively save memory resources.

[0106] Next, combine Figure 6 Explain regular cleaning.

[0107] Figure 6 A schematic diagram of periodic cleaning provided in an embodiment of the present application. Figure 6As shown, multiple historical link information corresponds to multiple historical timestamps, and multiple historical security protocol links correspond to multiple historical timestamps. The link information to be cleaned or the security protocol link to be cleaned is determined according to the interval between the historical timestamp and the current time. The link information to be cleaned is deleted, and the security protocol link to be cleaned is disconnected.

[0108] In this feasible implementation, memory resources can be effectively saved by regularly cleaning up link information or security protocol links.

Figure 7 As shown, the remote link establishment device 70 may include: a receiving module 71, an establishment module 72, a determination module 73, and an association module 74, wherein:

[0110] The receiving module 71 is used to receive a link establishment request sent by a user terminal, where the link establishment request includes a target user identifier.

[0111] The establishing module 72 is used to establish a target communication protocol link between the middleware and the user end according to the link establishment request.

[0112] The determination module 73 is used to determine the target security protocol link according to the target user identifier and the cache, and the target security protocol link is the link between the middleware and the server.

[0113] The association module 74 is used to associate the target communication protocol link with the target security protocol link to establish a remote link between the client and the server.

[0114] Optionally, the receiving module 71 may execute Figure 2 S201 in the embodiment.
