+## 1. 申请应用
+
+### 1.1 登录钉钉开发者中心
+
+1. 登录钉钉开发者中心：[钉钉开发者中心](https://open-dev.dingtalk.com/)
+2. 使用有管理员权限的钉钉账号扫码登录
+    1. 如果仅做测试的话，可以点击右上角，选择“企业注册”，按照提示创建企业
+    2. 创建完成后打开钉钉APP
+    3. 选择工作台
+    4. 点击左上角下拉框，选择刚刚创建的企业
+    5. 点击右上角加号选择扫一扫，重新扫码登录
+    6. 注：初次进入会被邀请填写一个问卷，如果是测试，则随便填就可
+
+
+### 1.2 创建第三方授权应用
+
+1. 在开发者管理控制台，选择“应用开发”
+2. 点击左侧菜单的【移动接入应用-登录】
+3. 然后点击右上角的【创建扫码登录应用授权】
+4. 填写基本信息
+![](doc/media/oauth/a6f3f46b.png)
+5. 创建后即可看到 appId 和 appSecret。
+
+
+记录以下三个信息：`appId`、`appSecret`和`回调域名`，后面我们会用到。
+
+
+## 2. 集成JustAuth
+
+### 2.1 引入依赖
+
+```xml
+<dependency>
+  <groupId>me.zhyd.oauth</groupId>
+  <artifactId>JustAuth</artifactId>
+  <version>${latest.version}</version>
+</dependency>
+```
+
+`${latest.version}`表示当前最新的版本，可以在[这儿](https://github.com/justauth/JustAuth/releases)获取最新的版本信息。
+
+### 2.2 创建Request
+
+```java
+AuthRequest authRequest = new AuthDingTalkRequest(AuthConfig.builder()
+                .clientId("Client ID")
+                .clientSecret("Client Secret")
+                .redirectUri("应用回调地址")
+                .build());
+```
+
+### 2.3 生成授权地址
+
+我们可以直接使用以下方式生成第三方平台的授权链接：
+```java
+String authorizeUrl = authRequest.authorize(AuthStateUtils.createState());
+```
+这个链接我们可以直接后台重定向跳转，也可以返回到前端后，前端控制跳转。前端控制的好处就是，可以将第三方的授权页嵌入到iframe中，适配网站设计。
+
+
+### 2.4 以上完整代码如下
+
+```java
+import me.zhyd.oauth.config.AuthConfig;
+import me.zhyd.oauth.request.AuthDingTalkRequest;
+import me.zhyd.oauth.model.AuthCallback;
+import me.zhyd.oauth.request.AuthRequest;
+import me.zhyd.oauth.utils.AuthStateUtils;
+import org.springframework.web.bind.annotation.PathVariable;
+import org.springframework.web.bind.annotation.RequestMapping;
+import org.springframework.web.bind.annotation.RestController;
+
+import javax.servlet.http.HttpServletResponse;
+import java.io.IOException;
+
+
+@RestController
+@RequestMapping("/oauth")
+public class RestAuthController {
+
+    @RequestMapping("/render")
+    public void renderAuth(HttpServletResponse response) throws IOException {
+        AuthRequest authRequest = getAuthRequest();
+        response.sendRedirect(authRequest.authorize(AuthStateUtils.createState()));
+    }
+
+    @RequestMapping("/callback")
+    public Object login(AuthCallback callback) {
+        AuthRequest authRequest = getAuthRequest();
+        return authRequest.login(callback);
+    }
+
+    private AuthRequest getAuthRequest() {
+        return new AuthDingTalkRequest(AuthConfig.builder()
+                .clientId("API Key")
+                .clientSecret("Secret Key")
+                .redirectUri("应用回调地址")
+                .build());
+    }
+}
+```
+授权链接访问成功后会看到以下页面内容：
+![](doc/media/oauth/5baf57ea.png)  
+
+点击“授权”即可完成百度的 OAuth 登录。
+
+## 3. 授权结果
+
+注：数据已脱敏
+
+```json
+{
+    "code":2000,
+    "data":{
+        "gender":"UNKNOWN",
+        "nickname":"码上行动",
+        "rawUserInfo":{
+            "nick":"码上行动",
+            "unionid":"4FiSzxIAgiEiE",
+            "dingId":"$:LWCP_xYfqxZ3z99w==",
+            "openid":"hHkfeC0xxfLr85zQiEiE",
+            "main_org_auth_high_level":false
+        },
+        "source":"DINGTALK",
+        "token":{
+            "expireIn":0,
+            "openId":"hHkfeC0XNixr85zQiEiE",
+            "unionId":"4FiSzv7YnxIE5IAgiEiE"
+        },
+        "username":"码上行动",
+        "uuid":"4FiSzv7YnxIE5IAgiEiE"
+    }
+}
+
+```
+
+## 3. 推荐
+
+官方推荐使用 [JustAuth-demo](https://github.com/justauth/JustAuth-demo) 示例项目进行测试。
+
+使用步骤：
+1. clone： [https://github.com/justauth/JustAuth-demo.git](https://github.com/justauth/JustAuth-demo.git)
+2. 将上面申请的应用信息填入到`RestAuthController#getAuthRequest`方法的对应位置中：
+![](doc/media/oauth/e1a40945.png)
+3. 启动项目，访问 [http://localhost:8443](http://localhost:8443)
+4. 选择对应的平台进行授权登录
+![](doc/media/oauth/da2bc692.png)
+5. 登录完成后，可以访问[http://localhost:8443/users](http://localhost:8443/users)查看已授权的用户
+![](doc/media/oauth/dbe6bcae.png)
+
+注：
+1. 如果直接使用 JustAuth-demo 项目进行测试，那么在配置测试应用的“回调地址”时要严格按照以下格式配置：`http://localhost:8443/oauth/callback/{平台名}`
+2. 平台名参考 `JustAuthPlatformInfo` 枚举类 `names`
