It achieves the interconnection between the internal control system and management information system of the enterprise, optimizes the configuration of manufacturing resources, and integrates and shares data resources by building an open cloud platform with data as the core, efficient resource allocation, and active innovation.

[0003] Transaction middleware is a software system for application transactions provided by the industrial Internet platform. It provides a development environment and transaction processing platform for application systems through a distributed architecture, shielding heterogeneous environments and supporting rapid response of high-concurrency processing.

[0004] Transaction middleware is widely used in the core online transaction systems of manufacturing, finance, transportation, communications, electricity, nonferrous metals and petrochemical industries, helping these companies achieve key business.

[0005] In actual application, due to performance, security and other reasons, transaction middleware often uses private protocols for data communication. The client needs to connect to the application access interface provided by the server and complete resource calls after forwarding through multiple layers of application protocols. Therefore, the server cannot widely share the application services it carries through the industrial Internet platform.

[0006] In order to overcome the existing functional deficiencies, the present invention proposes a gateway system and method for implementing REST access services based on transaction middleware, which can effectively improve the working efficiency of the application system.

[0061] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0062] Example 1

[0063] A gateway system for implementing REST access services based on transaction middleware according to the present invention includes:

[0064] The transaction middleware software system adopts a distributed architecture, which consists of the application interface layer, service framework layer, data access layer and basic support layer from top to bottom. It has distributed transaction processing and application communication functions, and provides a variety of comprehensive services to establish, run and manage application systems, such as Figure 1 shown.

[0065] The application interface layer mainly includes client programs, application programming interfaces, web browsers, third-party software tools, and management consoles. The management console is a user management interface that provides administrators with management and configuration functions for application services.

[0066] The service framework layer includes listeners responsible for handling external concurrent call connections and parsing request data, gateway systems (including private gateways and REST gateways), BBS bulletin boards responsible for application interaction, system management, application servers, transaction processing, running real-time libraries and other functional modules.

[0067] The data access layer is composed of application service programs written by users and is responsible for processing various types of business data.

[0068] The basic support layer is responsible for supporting heterogeneous hardware, networks, operating systems, and database servers.

[0069] The application interface layer, service framework layer, data access layer and basic support layer constitute the enterprise transaction middleware platform, which enables developers to establish cross-platform, interoperable application systems, and coordinate the unified and centralized data service resource processing platform and independent and decentralized application clients to jointly realize integrated resource management under the Industrial Internet platform.

[0070] The transaction middleware gateway is a software system that implements application layer protocol conversion and is also the entry and exit for information interaction with external systems. The private gateway uses the enterprise's private protocol for data communication, and the client program calls a specific application programming interface to complete functions such as connecting to the gateway system, requesting services, processing business data, and canceling connections, thereby protecting data security and privacy.

[0071] REST gateway is a network software system based on REST architecture style and adopts the international open standard HTTP (Hypertext Transfer Protocol) / 1.1 protocol. It uses a unified interface specification to define the operation mode of resources, uses the Uniform Resource Identifier URI (Uniform Resource Identifier) ​​to identify the resource location, and uses media types (such as JSON, XML, etc.) for data interaction.

[0072] Through the HTTP protocol, the REST gateway can achieve loose coupling of data interaction between WEB browsers, client programs and server-side application business processing programs, and provide a convenient, flexible, secure interface calling method based on the browser / server-side architecture at the service framework layer. At the same time, it also has basic communication transmission functions such as load balancing, flow control, SSL encryption, and authentication.

[0073] The REST gateway consists of two functional modules: listener and gateway processor. Figure 2 shown.

[0074] Each transaction middleware REST gateway system contains a listener and several gateway processors that can be flexibly configured, which can effectively improve the system throughput and server-side processing capabilities. The client program completes the network transmission of the request data through the HTTP protocol, and the gateway processor efficiently transmits the application data contained in the request message to the application server for processing through inter-process communication. After obtaining the response data, it replies with a response message. The main business functions are described as follows:

[0075] 1. The client calls the REST resource address to establish a socket connection with the listener.

[0076] 2. The listener passes the socket connection handle to the gateway processor, and then the client's communication connection is handled by the latter, and the listener is no longer involved.

[0077] 3. The gateway processor is responsible for transmitting data at the TCP layer, and decrypting and parsing the HTTP request message through the upper-layer SSL protocol to obtain application data.

[0078] 4. The gateway processor passes the data to the application server, which returns the response data after executing the service program.

[0079] 5. After the gateway processor obtains the response data, it encapsulates it into an HTTP response message, and then encrypts it through the SSL protocol and replies to the client.

[0080] Among them, the listener module includes:

[0081] The listener module is the network entrance of the transaction middleware software system. The client connects to the REST gateway system through the listener. The listener is responsible for listening to the HTTP / S protocol port and the Unix Domain Socket port, receiving connections from external clients and internal gateway processors respectively.

[0082] It selects the gateway processor according to the random scheduling strategy of load balancing or the lightest load strategy and passes the client connection handle to it, and the latter interacts with the client for data. The functional flow is as follows Figure 3 shown.

[0083] "Load balancing random scheduling strategy" and "lightest load strategy" are proprietary technologies that the transaction middleware has implemented.

[0084] The gateway processor module includes:

[0085] The gateway processor responsible for parsing and encapsulating HTTP request and response messages is the core module of the REST gateway system and is also the basic component for quickly calling application services and handling high-concurrency connections.

[0086] Its underlying architecture is based on the event-driven software design pattern, adopts the reactor programming model of single-threaded asynchronous processing of concurrent connections, uses the operating system's I / O multiplexer (select / poll function) as the basic component of the event-driven loop, continuously checks signal events, timing events, I / O handle input and output read and write events, waits for timing events to be triggered, and then processes the remaining ready network events, dispatches data, executes the callback function registered in advance for the event, notifies the business object to receive data, and then completes the protocol parsing of the HTTP request message.

[0087] It combines the efficient inter-process communication mechanism within the transaction middleware to serially and asynchronously process various network events while reading the response data processed by the application from the memory in a non-blocking manner, thereby realizing the efficient communication function of the system.

[0088] The workflow of the gateway processor module is as follows Figure 4 shown.

[0089] like Figure 5 As shown, the gateway processor module consists of four functional sub-modules: a connection management sub-module, an information security processing sub-module, an HTTP protocol processing sub-module, and an application data interaction sub-module.

[0090] The connection management submodule is responsible for the communication between the gateway processor and the listener, establishing and managing the connection with the external client request, and establishing the association between the socket connection handle and the SSL layer, setting data read and write events, and ensuring stable and efficient data transmission. The functions are as follows:

[0091] 1. Responsible for connecting, disconnecting, or reconnecting the listener.

[0092] 2. Receive the client socket connection handle forwarded by the listener.

[0093] 3. Establish an association between the connection handle and the SSL layer.

[0094] 4. Interact with the SSL layer to exchange keys and authenticate to establish a secure connection through the information security processing submodule.

[0095] 5. Set the callback function of data read and write events for the socket connection handle.

[0096] 6. Notify the listener of the running status of the gateway processor in real time.

[0097] The information security processing sub-modules include:

[0098] The Secure Sockets Layer (SSL) protocol is an industrial Internet confidentiality standard used to encrypt and ensure communication security. It is located between the TCP transport layer and the application layer, establishing a secure communication channel for both the client and the server.

[0099] The information security processing submodule is responsible for encrypting and decrypting the actual transmission messages for both parties in communication. Among them, verifying certificates, identity authentication, selecting algorithms, negotiating protocol versions and keys are the key links for accurate and efficient information security processing.

[0100] First, the SSL protocol establishes a secure channel based on the handshake protocol and the record protocol through the following steps: Figure 6 shown.

[0101] Afterwards, the information security processing submodule will use the generated symmetric key to encrypt and decrypt the data message. The rules are as follows:

[0102] 1. The plaintext data that arrives after decryption at the SSL layer is notified by the event-driven callback mechanism to the HTTP protocol processing submodule for parsing.

[0103] 2. The plaintext data sent down is encrypted with the symmetric key of the SSL layer and sent to the outside through the TCP transport layer.

[0104] The above mechanism realizes the data encryption function during the transmission process and provides a more secure and reliable network communication service.

[0105] HTTP protocol processing submodules include:

[0106] This submodule is used to parse and encapsulate HTTP / 1.1 request and response messages.

[0107] First, it is responsible for parsing the received plaintext data according to the HTTP / 1.1 protocol requirements, removing the start line, header field and empty line terminator of the HTTP request message, collecting the subsequent data body according to the length field value of the header, and then handing it over to the application server for processing. The parsing workflow is as follows: Figure 7 As shown:

[0108] The application service interaction submodule includes:

[0109] The REST gateway uses the FML32 (Field Management Language) format as the data structure for interaction between the gateway and the application server, flexibly realizing the dynamic construction of the application data structure.

[0110] The application service interaction submodule reads the processed response data from the memory through the inter-process communication mechanism, then encapsulates it into an HTTP response message and replies to the client after encryption through the information security submodule.

[0111] The present invention also provides a gateway system for implementing REST access services based on transaction middleware. The gateway system for implementing REST access services based on transaction middleware can be implemented by executing the process steps of the gateway system implementation method for implementing REST access services based on transaction middleware, that is, those skilled in the art can understand the gateway system implementation method for implementing REST access services based on transaction middleware as a preferred implementation mode of the gateway system for implementing REST access services based on transaction middleware.

[0112] Those skilled in the art know that, in addition to realizing the system and its various devices, modules, and units provided by the present invention in a purely computer-readable program code, it is entirely possible to realize the same functions in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps.

[0113] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
