Step S102, taking each key name as a key, and taking the value of the key value reference address corresponding to the key name in a data source as a key value, so as to generate a parameter object with a plurality of key value pairs;
wherein each key value pair has a key and a corresponding key value.
Step S103, a request corresponding to the request mode is sent to a server based on the parameter object;
wherein the request carries a request parameter.

Because of the diversity of the interface modules, the request return values may vary from one request to another.
The interface module in the invention adopts a predefined mode and uses a Schema format similar to a data source to describe a multi-layer object structure of a request return value.
The data pattern of the request return value in this embodiment is as follows:
step S105, the request return value is converted into a return value Schema object in Schema format, and the return value Schema object is injected into the data source.

The preset symbol may be'? ' that is, the present embodiment uses the key value to the character string? ' concatenate after the server address url, generating the target request address.
In practical application, HTTP interface requests are distinguished according to methods, and are mainly divided into GET, POST and the like, and the problem of cross-domain is solved by a JSONP executing script mode.

The JSONP method utilizes the characteristic of script labels, and uses the dynamically created script labels to execute a section of JavaScript script on a remote server to achieve the function of acquiring server data.
The script tag will automatically send a request to the server of the src address and execute the obtained JavaScript after setting the src parameters.
(3) For the POST request, step S103 may specifically include:

"label" means "c0",// data name
"cnName": value of "c 0"// chinese meaning of data
},{
"key" d.0.e.f ",// the d.0.e.f value in the corresponding request return value data pattern is 2
