Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of an interface access request processing method provided by the present invention, and fig. 3 is a third schematic flowchart of an interface access request processing method provided by the present invention, as shown in fig. 1, the method includes:
step S110, receiving an interface access request initiated by a front end; the interface access request comprises a module identifier, a service identifier, a method identifier and a request parameter of the micro service;
step S120, the interface access request is routed to a server and a micro service module corresponding to the module identifier according to the module identifier, so that the server further searches a corresponding service instance in the micro service module according to the service identifier, acquires a corresponding method and a parameter definition list in the service instance according to the method identifier, and calls the method based on the request parameter and the parameter definition list, thereby acquiring an interface access request processing result;
step S130, receiving the interface access request processing result returned by the server, and sending the interface access request processing result to the front end.
The interface access request processing method provided by the invention can be applied to an API (application program interface) gateway. The API gateway receives an interface access request initiated by a front end; the interface access request comprises a module identifier, a service identifier, a method identifier and a request parameter of the micro service. And after receiving the interface access request, the API gateway routes the interface access request to the micro-service module corresponding to the server according to the module identifier.
As shown in fig. 3, there is a Dispatch (a function module) in each micro-service module of the server, which may have the following functions: firstly, a method calling process is carried out in the micro service module according to the service identifier, the method identifier and the request parameter in the interface access request; uniformly processing the method calling result and returning the method calling result to the front end; and thirdly, intercepting the exception generated in the calling process of the method and returning friendly prompt information to the front end. For example, when an exception occurs in the method calling process, the prompt message of 'method calling failure' is returned to the front end; the process fully considers the possible situations in the method calling process, gives feedback to the situation of method calling failure in time, and optimizes the human-computer interaction experience; fourthly, the parameters in the request protocol are organized and converted into the format required by the target method, and the method is called.
It should be noted that, in step S120, after the interface access request is routed to the micro service module corresponding to the module identifier, the module finds a corresponding service instance from the bean managed by spring through the servicebeans name (service identifier), and can obtain a method and a parameter definition list corresponding to the methodName (method identifier) through the java reflection mechanism. The Spring is a layered JavaSE/EE full-stack (one-stop) lightweight open-source framework, which is convenient for integrating various excellent frameworks and testing programs; a bean is equivalent to defining a component that is used to implement a certain function. In the process, only specific parameter objects need to be instantiated according to parameter names, parameter types and parameter values transmitted from the front end, and the method call can be executed through a java reflection mechanism. The parameter name and the parameter type can be directly obtained in the parameter definition, then a character string is obtained from the Map through the parameter name, and finally the character string is converted into a value object corresponding to the parameter type, so that the required parameter value transmitted by the front end is obtained. The conversion needs to judge the parameter type, if the type is simple, the conversion can be directly carried out, and if the type is a composite object type, the conversion can be carried out by transmitting the JSON field to a javaBean object. A Map is a data storage structure that can be viewed as a container that stores elements according to keys (keys) that are similar to subscripts, where keys (keys) can be any type of object, where there cannot be duplicate keys (keys) in the Map, and each Key (Key) has a corresponding value (value).
And after obtaining the interface access request processing result, the server sends the interface access request processing result to the API gateway. The API gateway receives an interface access request processing result returned by the server and feeds the interface access request processing result back to the front end, so that the processing of the corresponding interface access request is realized.
According to the interface access request processing method provided by the invention, the interface access request is subjected to layered processing comprising the module identifier, the service identifier and the method identifier, when the interface access request is initiated at the front end, the interface access request is routed to the corresponding micro-service module according to the module identifier, then the corresponding service instance is obtained according to the service identifier, and the corresponding method is called according to the method identifier, so that the target method is quickly called, the processing efficiency and the processing accuracy of the interface access request are improved, the problem of frequent change of internal codes of an API gateway caused by method updating is avoided, the integral maintainability is improved, and the front end friendliness is realized.
According to the interface access request processing method provided by the present invention, in the present invention, the receiving of the interface access request initiated by the front end includes: receiving an interface access request initiated by a front end based on an HTTP interface protocol; the protocol format of the HTTP interface protocol includes the module identifier, the service identifier, and the method identifier, and the request parameter exists in a request body corresponding to the protocol format of the HTTP interface protocol or the interface access request.
For example, the protocol format of the HTTP interface agreed between the front end and the server may be:http://${domain}/ ${module}/${servcieBeanName}/${custom}/${method name }, in the above interface protocol, { domain } is the domain name, { module } is the module ID, { servcieeBeanName } is the service ID, and { custom } is the special ID Requirement parameter, { MethodName } is the method identification.Request parameters may also be set in the protocol format of the HTTP interface.
The HTTP request message consists of three parts, respectively: the system comprises a request line, a request header and a request body, wherein the request line consists of a method, a URL and an HTTP version, the method refers to what operation is specifically executed by a command browser, the URL represents an address of a server, and the HTTP version represents a protocol which is specifically a few versions; the request header is composed of a limited field name and a limited field value, and the field name and the field value are additional information of the request message, such as 7/9/2021, date, data type, language or compression format, and the like; the specific components of the request body depend on specific request content, that is, the request body is used for carrying HTTP request data, is used for carrying information of specific request parameters, and is the core for embodying the specific HTTP request content. The request parameters may also be present in the request body to which the interface access request corresponds.
According to the interface access request processing method provided by the invention, the interface access request is designed into a standard request format based on an HTTP (hyper text transport protocol) interface protocol, the HTTP interface protocol comprises a module identifier, a service identifier and a method identifier, the readability of the interface access request at the front end is improved, the interface access request can be quickly processed on a back-end server based on the interface protocol, meanwhile, request parameters exist in the protocol format of the HTTP interface protocol or a request body corresponding to the interface access request, and the flexibility is improved.
According to the interface access request processing method provided by the invention, the name of the request parameter is consistent with the parameter name of the method in the service instance corresponding to the interface access request.
For example, an interface access request is initiated at the front end:http://${domain}/ com.ke.sinan.UserService/userInfoparam＝username. Ke. The name of the request parameter is set to be the username, so that the request parameter is consistent with the parameter name of the method in the service instance corresponding to the interface access request, the method can be quickly called, and the method is more friendly to the front end.
The interface access request processing method provided by the invention is beneficial to ensuring the one-to-one correspondence between the interface access request and the method calling process in the micro service module by keeping the name of the request parameter in the interface access request consistent with the name of the parameter in the calling method in the micro service module, thereby improving the processing efficiency and the processing accuracy of the interface access request and being more friendly to the front end.

It should be noted that the API gateway 400 is configured to receive the interface access request, specifically: receiving an interface access request initiated by a front end based on an HTTP interface protocol; the protocol format of the HTTP interface agreed between the front end and the server may be: http:// $ { domain }/$ { module }/$ { servciebenname }/$ { custom }/$ { method Name }, in the above interface protocol, { module } is module identification, { servciebenname } is service identification, and { methodName } is method identification.
After receiving the interface access request, the API gateway routes the specific interface access request to a corresponding micro-service module on the server according to the module identifier in the interface access request; issuing a Dubbo service of a DispatchService in each micro service module, wherein the DispatchService represents a functional module in the micro service module for processing an interface access request, the DispatchServices of different micro services are distinguished by group attributes of Dubbo, the group value of a specific micro service corresponds to $ { module } of the protocol, the API gateway provides a method for uniformly processing a Controller by a request, the request is processed by @ RequestMapping (value: "/{ module }/{ serviceBeanName }/{ custom }"), all request parameters are received by Map, the core logic of the processing is to call the DispatchServiceService of the specified module by Dubbo, route the request to the specified micro service module, and transmit { serviceName }, { custom }, { other previous }, and other { quantity } past parameters.
Specifically, after the interface access request is routed to the micro-service module corresponding to the module identifier, the module finds a corresponding service instance from a bean managed by spring through the servicebean name, and can obtain a method and a parameter definition list corresponding to the methodName through a java reflection mechanism. In the process, only specific parameter objects need to be instantiated according to parameter names, parameter types and parameter values transmitted from the front end, and the method call can be executed through a java reflection mechanism. The parameter name and the parameter type can be directly obtained in the parameter definition, then a character string is obtained from the Map through the parameter name, and finally the character string is converted into a value object corresponding to the parameter type, so that the required parameter value transmitted by the front end is obtained. The conversion needs to judge the parameter type, if the type is simple, the conversion can be directly carried out, and if the type is a composite object type, the conversion can be carried out by transmitting the JSON field to a javaBean object.
According to the interface access request processing system provided by the invention, the interface access request is subjected to layered processing comprising the module identifier, the service identifier and the method identifier, when the interface access request is initiated at the front end, the interface access request is routed to the corresponding micro-service module according to the module identifier, then the corresponding service instance is obtained according to the service identifier, and the corresponding method is called according to the method identifier, so that the target method is quickly called, the processing efficiency and the processing accuracy of the interface access request are improved, the problem of frequent change of internal codes of an API gateway caused by method updating is avoided, the integral maintainability is improved, and the front end friendliness is realized.
