Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
According to an aspect of an embodiment of the present invention, a method for application protocol self-adaptation is provided.
Fig. 1 is a schematic diagram of a main flow of a method for application protocol self-adaptation according to an embodiment of the present invention, and as shown in fig. 1, the method for application protocol self-adaptation includes:
step S101, receiving a request message;
step S102, comparing the request message with feature codes preset by each application protocol, and determining a target application protocol corresponding to the request;
step S103, determining a target application protocol processor corresponding to the target application protocol, and forwarding the request packet to the target application protocol processor.
The feature code refers to a feature of the application protocol. The specific content of the feature code is determined according to the protocol, as long as the feature code can be used for identifying different application protocols. When different application protocols are identified according to the feature codes, the identification can be carried out according to only one feature code or can be carried out by combining a plurality of feature codes.
Fig. 2 is a schematic diagram illustrating a method for application protocol self-adaptation according to an embodiment of the present invention. In this example, an application protocol based on the TCP transport layer protocol is taken as an example. As shown in fig. 2, the web services Layer binds two ports 80 and 443 for receiving TCP requests and requests for SSL (Secure Sockets Layer) connections, respectively. After receiving the request, the network service layer forwards the request message to the protocol identification module to identify a specific application protocol, then the protocol identification module is sent to a corresponding protocol processor to process the request message, and a processing result is sent to the service system. Illustratively, HTTP request messages are handled by an HTTP protocol handler, FTP request messages are handled by an FTP protocol handler, AS2 request messages are handled by an AS2P protocol handler, and SOAP request messages are handled by a SOAP protocol handler.
Optionally, the method further comprises: pre-storing mapping relations between each application protocol and the corresponding feature codes thereof; comparing the request message with the feature codes preset by each application protocol, wherein the comparing comprises the following steps: and comparing the request message with the mapping relation. And the comparison is carried out according to the mapping relation, so that the efficiency is high.
Optionally, the method further comprises: pre-registering mapping relations between each application protocol and the corresponding application protocol processor; determining a target application protocol processor corresponding to the target application protocol, comprising: and according to the mapping relation, taking an application protocol processor corresponding to the target application protocol as the target application protocol processor. And the comparison is carried out according to the mapping relation, so that the efficiency is high.
Optionally, the application Protocol is implemented based on a TCP (Transmission Control Protocol) transport layer Protocol, and includes at least one of: FTP, HTTP, SOAP, AS2, SMTP, SFTP, OFSTP.
The Transport Layer (Transport Layer) is the fourth Layer of an Open System Interconnection (OSI) communication protocol, and is responsible for reliably transmitting data to a corresponding port and realizing end-to-end data transmission. The transport layer protocol includes: transmission control protocol (TCP protocol) and user datagram protocol (UDP protocol). The TCP protocol is a connection-oriented reliable transport protocol. When the TCP protocol is used for communication, a three-step handshake is first performed to establish a connection between two communicating parties. The TCP protocol provides a mechanism for data acknowledgement and data retransmission, and ensures that the transmitted data can reach the opposite party of communication. The UDP protocol is a connectionless, unreliable transport protocol. When the UDP protocol is adopted for communication, connection does not need to be established, data can be directly sent to an IP address, but whether the opposite side can receive the data cannot be guaranteed. The application layer is a seventh layer of an OSI (Open System interconnection) communication protocol, and the application protocol is a protocol specification of the application layer.
In the invention, a plurality of application protocols can be bound on the same port, and when a connection request occurs, a corresponding protocol processor is automatically selected for processing according to an actual request. Optionally, the method further comprises: the application protocol processor is provided in a plug-in manner. Illustratively, an Interface which each application protocol needs to support is defined, and the implementation of each application protocol is provided in the form of JAR (Java Archive, which is a software package file format) package, and is loaded using the technology of SPI (Serial Peripheral Interface)/OSGI (Open Service Gateway Initiative) at the framework level. The application protocol processor supports extension and dynamic plugging and unplugging, and has good universality.
According to a second aspect of the embodiments of the present invention, there is provided an apparatus for application protocol self-adaptation.

The network service module 301 is responsible for monitoring connection requests such as TCP and SSL, and packages specific request contents into a message after receiving the connection request, and forwards the message to the protocol identification module 302.
The protocol identification module can pre-store mapping relations between each application protocol and the corresponding feature codes thereof; comparing the request message with the feature codes preset by each application protocol, wherein the comparing comprises the following steps: and comparing the request message with the mapping relation.
After the protocol identification module determines the target application protocol, the protocol registration module 303 is invoked to determine the target application protocol processor. Optionally, the protocol registration module registers in advance a mapping relationship between each application protocol and its corresponding application protocol processor; determining a target application protocol processor corresponding to the target application protocol, comprising: and according to the mapping relation, taking an application protocol processor corresponding to the target application protocol as the target application protocol processor.
The protocol registration module 303 is used to manage the respective application protocol processors. New application protocol processors may be extended or application protocol processors already registered may be deleted by the registrable module 303.

a protocol registration module 403, configured to determine a target application protocol processor corresponding to the target application protocol, and forward the request packet to the target application protocol processor;
a processor module 404 that provides the application protocol processor in a plug-in manner.
The application protocol processor is provided in a plug-in manner, which facilitates expansion.

At initialization, the protocol identification module 402 predefines and loads the feature codes of the various application protocols. The protocol registration module 403 scans various application protocol processors and loads the corresponding relationship between each application protocol and the application protocol processor. The processor module 404 scans through the system, finds the corresponding application protocol processor and loads it. The network service module 401 is then started and the specific port is bound.
After receiving the connection request, the network service module 401 encapsulates the specific request content into a message (a character string array) and forwards the message to the protocol identification module 402. Specifically, the network service layer sends the character string arrays (these character string arrays are the message content) assembled by the protocol layer to the protocol identification module 402, the protocol identification module 402 identifies the target application protocol according to the feature codes included in the character string arrays, and then establishes the binding between the protocol and the network channel. )
After receiving the message, the protocol identification module 402 compares the feature code identification contained in the message content with the feature code of the registered application protocol, and identifies the target application protocol.
The protocol registration module 403 searches a corresponding target application protocol processor from the registered protocol processors according to the target application protocol. If the current connection can not be found, returning an error message, and disconnecting the current connection; if the message is found, the service interface is called by the target application protocol processor to process the corresponding message, and corresponding information is obtained from the service interface and returned to the client after the processing is finished.
