Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, various implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.

[0024] The first embodiment of the present invention relates to an exception handling method. By assigning the variable to a preset value, when obtaining the value of the variable, the program will not exit abnormally due to the assignment of the variable to NULL, which reduces communication costs and code r...

Abstract

The embodiment of the invention relates to the technical field of networks, in particular to an exception handling method and device, electronic equipment and a nonvolatile storage medium. The exception handling method comprises the steps of acquiring the content of front-end error reporting; determining that the error reporting type is a preset error type according to the error reporting content,and obtaining a variable corresponding to the preset error type from the error reporting content; and assigning a variable corresponding to the preset error type as a preset value. According to the method and the device, the variable is assigned to the preset value, so that when the value of the variable is obtained, program exception quitting caused by the fact that the variable is assigned to be the NULL is avoided, the communication cost and code redundancy are reduced, the code complexity is reduced, and the code running efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of network technologies, and in particular to an exception handling method, device, electronic equipment, and storage medium. Background technique [0002] At present, in the process of front-end and back-end interaction, the back-end transmits a lightweight data exchange format (JavaScript Object Notation, JSON) string to the front-end through the web development technology (AJAX) for creating interactive web applications, and the front-end converts JSON The string becomes an object of JSON type again, and each required field value is conveniently obtained through destructuring assignment. During this process, if an attempt is made to obtain the value of a field in an object, and the object is missing and assigned a value of NULL, an exception of a preset error type will be triggered and the program will exit. [0003] The inventor found that there are at least the following problems in the...
