+# JWT
+
+## 安装
+
+```shell
+go get git.tsl3060.com/openapi/go-security/jwt
+```
+
+将包放在你的项目文件夹下，并在 import 中添加以下内容:
+
+```golang
+import jwt "git.tsl3060.com/openapi/go-security/jwt"
+```
+
+## 基本使用
+
+### 获取服务器公钥
+
+访问[https://opendev.tsl3060.com/certs/publickey](https://opendev.tsl3060.com/certs/publickey)以获取服务器公钥
+
+### 配置并使用示例
+
+```golang
+// 设置公钥
+service, err := jwt.NewTokenService("public key")
+if err != nil {
+    return
+}
+// 校验解析token
+token, err := service.VerifyToken("token")
+if err != nil {
+    return
+}
+fmt.Println(token)
+```
