Android - how to get google plus access token?(Android - 如何获取 google plus 访问令牌?)

问题描述

您好，我在不使用带范围的 OAuth 2.0 客户端 ID 的情况下获取 google plus 访问令牌.但是使用此访问令牌不会获取电子邮件地址.如何获取用户邮箱?

Hello i am getting google plus access token without using OAuth 2.0 client ID with scopes. But with this access token does not fetch email address. How to fetch user email address?

带有和不带有 OAuth 2.0 客户端 ID 的 accesstoken 有什么区别吗?

Is there any difference between accesstoken with and without OAuth 2.0 client ID?

我使用了以下代码，

String accessToken="";
                    try {
                        accessToken = GoogleAuthUtil.getToken(
                                getApplicationContext(),
                                mPlusClient.getAccountName(), "oauth2:"
                                        + Scopes.PLUS_LOGIN + " "
                                        + Scopes.PLUS_PROFILE);

                        System.out.println("Access token==" + accessToken);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }

推荐答案

String accessToken = "";
try {
  URL url = new URL("https://www.googleapis.com/oauth2/v1/userinfo");
  // get Access Token with Scopes.PLUS_PROFILE
  String sAccessToken;
  sAccessToken = GoogleAuthUtil.getToken(
    LoginCheckActivity.this,
    mPlusClient.getAccountName() + "",
    "oauth2:"
      + Scopes.PLUS_PROFILE + " "
      + "https://www.googleapis.com/auth/plus.login" + " "
      + "https://www.googleapis.com/auth/plus.profile.emails.read");
} catch (UserRecoverableAuthException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();                  
  Intent recover = e.getIntent();
  startActivityForResult(recover, 125);
  return "";
} catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
} catch (GoogleAuthException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
}
