开源网关Apache APISIX启用JWT身份验证

说明：

• 本文APISIX的配置参考我之前写的《Ubuntu部署Apache APISIX》

创建最小API

首先，确保你已经安装了.NET 6 SDK。创建文件夹“MinimalApiDemo”，VS Code打开文件夹，打开终端

dotnet new web -o MinimalApiDemo
cd MinimalApiDemo

修改Program.cs

var builder = WebApplication.CreateBuilder(args);var app = builder.Build();

builder.WebHost.UseUrls("http://0.0.0.0:5001");

app.MapGet("/",()=>"Hello, World!");

app.MapGet("/protect/{name}",(string name)=>$"Hello, {name}!");

app.Run();

启动项目

dotnet run

浏览器打开“http://192.168.8.220:5001/protect/tom”，显示结果

Hello, tom!

创建消费者

创建两个消费者，管理员admin和用户user

{"username":"admin_role","plugins":{"jwt-auth":{"exp":86400,"key":"admin","secret":"admin1234567890"}}}

{"username":"user_role","plugins":{"jwt-auth":{"exp":86400,"key":"user","secret":"user1234567890"}}}

创建上游

创建公共API端点

为JWT身份验证创建公共API端点

/apisix/plugin/jwt/sign

​

{"uri":"/gen_token","name":"jwttoken","plugins":{"public-api":{"uri":"/apisix/plugin/jwt/sign"}},"status":1}

浏览器或者Postman等工具，请求如下链接，注意这里的key为admin

http://192.168.8.249:9080/gen_token?key=admin

得到admin的token

eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJrZXkiOiJhZG1pbiIsImV4cCI6MTcxNzc2ODcwNH0.YeuyvRJmRHwajqmFm6G8ffYtguIW4PFoZ7LY3iDO8Kg

同理，接下来使用key为user

http://192.168.8.249:9080/gen_token?key=user

得到user的token

eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJrZXkiOiJ1c2VyIiwiZXhwIjoxNzE3NzY4ODc0fQ.ZSpDGNmBHVjoKtLxxic6S5C4auNJx1FlAJThvJReq6k

创建测试路由

测试之前的最小API接口

http://192.168.8.220:5001/protect/tom

【更多】【查看】的内容如下

{"uri":"/protect/*","name":"protect","methods":["GET"],"plugins":{"consumer-restriction":{"whitelist":["admin_role"]},"jwt-auth":{}},"upstream_id":"516993931985027773","status":1}

测试JWT认证

使用Postman工具，访问如下接口

http://192.168.8.249:9080/protect/tom

Postman提示

{"message":"Missing JWT token in request"}

Headers中Key填写“Authorization”，Value填写“Bearer [token]”（注意Bearer和[token]之间有一个空格）

使用user的token

Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJrZXkiOiJ1c2VyIiwiZXhwIjoxNzE3NzY4ODc0fQ.ZSpDGNmBHVjoKtLxxic6S5C4auNJx1FlAJThvJReq6k

Postman提示如下。网关阻止了user用户请求

{"message":"The consumer_name is forbidden."}

接下来使用admin的token

Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJrZXkiOiJhZG1pbiIsImV4cCI6MTcxNzc2ODcwNH0.YeuyvRJmRHwajqmFm6G8ffYtguIW4PFoZ7LY3iDO8Kg

admin用户顺序访问受保护的接口
