Description

Method for verifying data of front-end receiving server
Technical Field
The present invention relates to the field of front-end data processing technologies, and in particular, to a method for verifying data received by a front-end server, an electronic device, and a computer-readable storage medium.
Background
The front-end and back-end development are separated and then typically contract the interface document. Although interface documentation is agreed, in rigorous development, neither the data sent by the front-end to the back-end nor the data sent by the back-end to the front-end is trustworthy. Therefore, the data structure and type need to be checked to ensure the logic correctness of the subsequent service.
With the frequent front-end and back-end communication, the checking is more and more, and very similar judgment logic is written, so that the code amount is increased, and the code is more obscure and difficult to maintain.
The data type of the front-end and back-end communication is typically json, and the prior art uses either the djv library or the ajv library to verify that the model data defined in the json-schema implementation library meets expectations. However, the model data includes necessary (bolt, string, number, array, object) types in json data, and also includes some attributes such as description information ($ id: unique identifier of current data; title: data description; default: default data value), and the attributes form a tree-shaped model data structure, so that the model data volume defined in the json-schema realization library is large, and the data structure is complex.
And comparing the model data with the real data during verification to obtain whether the model data is matched with the real data, wherein the matching returns true, and the mismatching returns false. Therefore, only a global check result can be returned, data after type fault tolerance cannot be returned, and fault tolerance also needs to be processed in each service.

The embodiment of the invention is not realized according to a json-schema draft, but encapsulates an XHR (XMLHttpRequest) module and mounts non-descriptive model data, so that the model data is more concise. And by binding the model data and the request interface, performing recursive check on the real data and the model data, recording error type logs, and correcting error types to obtain the processed expected data. The development does not consider the existence of error types any more, so that the code is simpler and is easy to maintain.
After the interface document is defined, the model data is defined according to the interface document, so that the model data is more concise.
For example:
take the following json data as an example
Figure BDA0002875389650000061
Figure BDA0002875389650000071
The prior art requires the generation of model data as follows
Figure BDA0002875389650000072
Figure BDA0002875389650000081
Obviously, the data size of the descriptive model data is relatively large, so the scheme uses the non-descriptive model data as follows:
Figure BDA0002875389650000082
the invention binds the model data and the request interface in a configuration mode, so that the later maintenance is simpler.
Figure BDA0002875389650000083
