jwt-go
Discontinued ARCHIVE - Golang implementation of JSON Web Tokens (JWT). This project is now maintained at:
In JavaScript, for example, it is convenient to implement such a mechanic in the axios library using interceptors.
For example, take a boilerplate application written in the Golang Echo web framework. It has already implemented registration and user login, updating a pair of tokens using a refresh token, and there is a set of tests. Next, we will consistently change it to get the desired result. There is also Swagger documentation here, which is handy to use to test our changes. Updates made to the boilerplate application code are available in the repository under the "feature/JWT-logout" branch.
The boilerplate application uses the dgrijalva / jwt-go library to work with JWTs. Besides the standard set of claims fields, this library allows you to describe additional fields. In the application, this makes it possible to write to the token the ID of the user to whom it was issued. The library supports the NewWithClaims () and Parse () functions used in the AuthHandler application to create and validate tokens. Also, the Echo framework has a JWT middleware that uses the specified library to validate tokens. This middleware is hooked up in the ConfigureRoutes () function of the template application that declares the routing.
