伙计们,

我正在寻找一个使用com.google.api.client.auth.oauth2.draft10.AccessTokenRequest.ResourceOwnerPasswordCredentialsGrant, 来验证用户而不使用基于 Web 的 UI的功能示例。尝试了课程中提供的示例(将https://server.example.com/authorize替换为https://accounts.google.com/o/oauth2/auth),但得到了 invalid_request 响应。这是发布到的正确 URL 吗?请求是否需要在其上设置其他属性?尝试像这样设置范围,但没有运气 request.set("scope", " https://www.googleapis.com/auth/calendar ")。还尝试设置 response_type,grant_type,任何帮助将不胜感激。这是代码(也附有maven项目):

测试.java

import com.google.api.client.auth.oauth2.draft10.AccessTokenErrorResponse;
import com.google.api.client.auth.oauth2.draft10.AccessTokenRequest.ResourceOwnerPasswordCredentialsGrant;
import com.google.api.client.auth.oauth2.draft10.AccessTokenResponse;
import com.google.api.client.http.HttpResponseException;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.jackson.JacksonFactory;
public class Test {
  public static void main(String[] args) throws Exception {
    try {
      ResourceOwnerPasswordCredentialsGrant request =
          new ResourceOwnerPasswordCredentialsGrant(
              new NetHttpTransport(), 
              new JacksonFactory(),
              "https://accounts.google.com/o/oauth2/auth", 
              "<client_id>", 
              "<client_secret>",
              "<user_username>", 
              "<user_password>");
      AccessTokenResponse response = request.execute();
      System.out.println("Access token: " + response.accessToken);
    } catch (HttpResponseException e) {
      AccessTokenErrorResponse response = e.response.parseAs(AccessTokenErrorResponse.class);
      System.out.println("Error: " + response.error);
    }
  }
}

Google OAuth2.0 授权服务器不支持资源所有者密码凭据流。如果您提供了避免使用基于 Web 的 UI 的原因,则可能有一些可用的解决方法 - 例如,企业设置中的服务帐户,您的应用可以代表用户执行操作。
