领英登录
1. 申请应用
1.1 创建第三方授权应用
- 登录领英开发者中心：领英开发者中心 (opens new window)
- 点击“Create App”按钮创建应用
- 填写基本信息。注：本例为了演示，在选择公司时随便填了一个
- 创建后进入应用详情页面，选择“Auth”标签，进入 OAuth 配置页面
- 配置回调地址
记录以下三个信息：Client ID、Client Secret和回调地址，后面我们会用到。
重要提示
“应用密钥”可保护你应用程序的安全，因此请确保其不会泄露！也不要与任何人共享你的“应用密钥”！！！
2. 集成JustAuth
2.1 引入依赖
<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 (opens new window)获取最新的版本信息。
2.2 创建Request
AuthRequest authRequest = new AuthLinkedinRequest(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：
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
import me.zhyd.oauth.config.AuthConfig;
import me.zhyd.oauth.request.AuthLinkedinRequest;
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 AuthLinkedinRequest(AuthConfig.builder()
.clientId("Client ID")
.clientSecret("Client Secret")
.redirectUri("回调地址")
.build());
}
}
授权链接访问成功后会看到以下页面内容： 
点击“连接”即可完成 OAuth 登录。

3. 推荐
官方推荐使用 JustAuth-demo (opens new window) 示例项目进行测试。
使用步骤：
- clone： https://github.com/justauth/JustAuth-demo.git (opens new window)
- 将上面申请的应用信息填入到
RestAuthController#getAuthRequest方法的对应位置中：
- 启动项目，访问 http://localhost:8443 (opens new window)
- 选择对应的平台进行授权登录
- 登录完成后，可以访问http://localhost:8443/users (opens new window)查看已授权的用户
注意
- 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} - 平台名参考
JustAuthPlatformInfo枚举类names
