Background technique

Computer interface calls refer to the process of communication and interaction between different software components, systems or services through interfaces. Interface calls are abstracted through interfaces, and different modules can be developed, tested, and deployed independently, promoting the modularization and decoupling of the system, thereby improving the flexibility and maintainability of software development. Interface call By defining standardized interfaces and protocols, different systems can make remote calls to achieve cross-network communication and collaboration. This distributed architecture enables the system to achieve the advantages of high availability, elastic scaling and load balancing, and also provides more Good security and isolation; integration through interfaces enables data sharing and function reuse. Interface standardization and standardization can provide universal access points, reduce the difficulty and cost of integration, and also promote communication between different systems. Interoperability; by splitting tasks into multiple independent interface calls, parallel processing and asynchronous execution of tasks are achieved, improving the system's response speed and concurrency capabilities; by encapsulating functions into interfaces, different teams can develop different tasks in parallel Modules work while maintaining interface consistency. This software organization method improves the maintainability and testability of the code, and is also conducive to the scale and collaborative development of the team.

Embodiment 1

Figure 1 is a flow chart of an interface dynamic calling method in Embodiment 1 of the present invention. This flow chart only shows the logical sequence of the method described in this embodiment. On the premise that there is no conflict with each other, in other possible embodiments of the present invention, the shown or Describe the steps.

The interface dynamic calling method provided by this embodiment can be applied to the interface calling end of the provider, and can be executed by the interface dynamic calling method device. The device can be implemented by software and/or hardware, and the device can be integrated in the terminal. For example: any smartphone, tablet or computer device with communication capabilities. Referring to Figure 1, the method implemented specifically includes the following steps:

Step 1: Obtain at least one first request parameter and corresponding parameter value through the interface calling end, and send an access request to the target service center, and obtain the interface self-interface of the target interface fed back by the target service center after receiving the access request. Description;

Step 2: Obtain the request parameter set of the target interface according to the interface self-description information;

Specifically, the target interface will register the request parameter set to the target service center to provide webservice services, so that the interface caller can obtain the interface self-description information by accessing the target service center (sending an access request) to prepare for subsequent interface calls. For example: when the interface program is started, the target interface registers the interface self-describing information to the target service center. Since the service center has different modules, the registration center module is automatically found through the described information, and the interface instance information list is maintained to form self-describing information. .

It should be noted that the target service center is an integrated functional module, consisting of a registration center module, a business module, a storage module, etc. Each functional module is independent of each other and performs its own duties.

Further, the request parameter set of the target interface includes: uniform resource locator URL, parameter identifier, parameter type, default value, and output parameter. When adjusting the parameter set in the future, the HTTP request carries parameters through the URL or passes the parameters through the function call method, thereby adjusting the request parameter set.

Step 3: Based on at least one first request parameter and the corresponding parameter value obtained by the interface caller, adjust the request parameter set to obtain an adjusted request parameter set;

According to at least one first request parameter and the corresponding parameter value provided by the interface caller, the request parameter set of the target interface is adjusted in a timely manner. The specific adjustment method is as follows:

If the second request parameter exists in the adjusted request parameter set and is the same as the first request parameter, the parameter value corresponding to the first request parameter will be assigned to the second request parameter, that is, the new adjusted parameter will overwrite the old parameter. , thereby achieving the purpose of adjusting the parameter request set;

If a third request parameter exists in the adjusted request parameter set and is different from the first request parameter, then assign a preset default value to the third request parameter;

Specifically, if there is a third request parameter and the default value of the third request parameter is set, when the third request parameter is the same as the first request parameter, the method of covering the above parameters is the same; when the third request parameter and the first request parameter are different If they are different, the default value in the request parameter set is assigned to the third request parameter.

If the fourth request parameter does not exist in the request parameter set, that is, it is not one of the five parameters of the uniform resource locator url, parameter identifier, parameter type, default value, and output parameter, and is different from the first request parameter, then Delete the first request parameter.

For example: set the interface calling end _Pi as the i-th first request parameter, and i is a natural number; Q _n is the request parameter set of the target interface, and there are n parameters in the request parameter set; if there is one in the request parameter set of Q _n Subset Q _k (second request parameter), when Q _k and Pi _are the same (0<k<n, both k and n are natural numbers), then assign the parameter value corresponding to _Pi to Q _k ; if Q _n There is a subset Q _a (the third request parameter) in the request parameter set. When Q _a and _Pi are different (0<k<n, k and n are both natural numbers), the default value in the request parameter set will be assigned The third request parameter.

Step 4: Combine the obtained at least one first request parameter and the adjusted request parameter set to call the target interface. When the parameters of the target interface change, the request parameters of the target interface can be dynamically adjusted.

In the embodiment of the present invention, if a target interface is given, after initialization, the self-describing information of the target interface is determined, and the first request parameter of the interface calling end is represented according to the self-describing information of the target interface. If the self-describing information of the target interface is adjusted or modified due to business needs, and the first request parameter of the interface caller is also changed, there will be a mismatch between the target interface and the interface caller, so the request parameter set will be changed. Adjust and implement the call to the target interface based on the adjusted request parameter set and the first request parameter provided by the interface caller, and when the self-describing information of the target interface changes, dynamically adjust the parameters of the target interface in a timely manner. , avoid manual adjustments and improve the compatibility of the interface caller, thus greatly improving the efficiency of the interface caller.

Specifically, the adjusted request parameter set is matched with the first request parameter of the interface caller to improve the accuracy of the interface call. The specific process is as follows:

Sort all parameters in the first request parameter and obtain the sorted first request parameter;

Based on the sorted first request parameter, the target interface is called and the response data returned by the target interface is processed.

Specifically, after determining the target interface to be called, all parameters in the first request parameters are sorted according to a specific sorting rule to obtain the sorted first request parameters, so as to obtain the first one of the first request parameters. Taking parameters as an example, by searching the self-describing information of the target interface, determine the name, type, value range and other information of the sorted first parameter, and build a request that conforms to the target interface specification based on the requirements of the sorted first parameter. , ensure that the type of the requested parameter is consistent with the required type of the target interface, and select an appropriate value within the value range.

Further, the target interface is called using methods such as HTTP requests and function calls, and the response results returned by the target interface are processed. The returned data is parsed and processed according to the interface self-description information of the target interface, and the response results of the interface calling end are verified to be as expected. Check Whether the response result contains the required information, combined with the required information for further processing and adjustment, the specific processing and adjustment process is as follows:

Obtain at least one first response parameter of the interface calling end, and obtain the target interface response parameter set;

If a second response parameter exists in the response parameter set and is the same as the first response parameter, then the position of the second response parameter in the response parameter set will be obtained, and the parameter value corresponding to the second response parameter will be obtained;

If the third response parameter does not exist in the response parameter set and is different from the first response parameter, the first response parameter is deleted.
