A method for generating and refreshing picture verification codes based on React

Abstract

The invention discloses a method for generating and refreshing picture verification codes based on React. Using the react framework, users can obtain pictures and verification codes directly from theserver through the operation of the user without storing data into session, so there will be no data confusion or time-consuming and unusable situations, the users can stay in operation for a certainperiod of time, the frequent operation of the users is reduced and the pressure of the server is reduced. The method improves the security of the website, and through the use of react, the picture isrefreshed in time, so that users have a better operation experience and feel that the system is formal trustworthy. The method can effectively prevent illegal users from malicious login programs to destroy, and is used to prevent dictionary attacks, machine registration and other issues.

Description

technical field [0001] The invention relates to the field of web technology, in particular to a method for generating and refreshing a picture verification code based on React. Background technique [0002] With the development of Internet technology, more and more users use Internet products. When a website has multiple users and high concurrency, it is easy to cause the website to crash. As a way to prevent users from frequently operating and illegal users from maliciously logging in to programs to destroy them, the picture verification code has a wide range of applications and is easy to operate. [0003] React is a very popular front-end development framework recently. As the View layer in MVC, it can be used to build UI, and it can also be applied to the construction of non-UI parts of web applications in the form of plug-ins, so that it can easily integrate with other JS frameworks. Integration, such as AngularJS. At the same time, React implements partial updates to...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the deficiencies in the above-mentioned background technology, provide a method based on React to realize the generation and refresh of picture verification codes, adopt the react framework, directly obtain pictures and verification codes from the server through the user's operation, and do not need to store the data in session, there will be no data confusion, timeliness and unusable situations, allowing users to stay for a certain period of time during operation, reducing frequent user operations, reducing server pressure; improving the security of the website, and at the same time through the use of react The timely refresh of the pictures allows users to have a better operating experience and makes users feel that the system is legitimate and trustworthy. It can effectively prevent illegal users from maliciously logging in to the program for damage, and is used to prevent dictionary attacks (violent guessing), machine registration and other problems.
