Android Google Play 服务为 blogger api 返回无效 token

Question

我已经获得了访问博客 API 的权限，我已经在我的开发者控制台上确认了这一点。 我还编写了一些代码，使用下面的一些代码通过 Google Play 服务执行 oAuth2。

String SCOPE ="oauth2:https://www.googleapis.com/auth/blogger";
GoogleAuthUtil.getToken(context, "myEmail@gmail.com", mScope);

它返回一个标记。正如它应该。 但是，一旦我尝试使用 token 访问 api，我就会收到错误消息。

Unexpected response code 403 for https://www.googleapis.com/blogger/v3/users/self/blogs

这是我的要求:

这是我的回应:

这是我获取 token 的 BaseActivity.java 代码:

public class BaseActivity extends Activity {

static final int REQUEST_CODE_PICK_ACCOUNT = 1000;
static final int REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR = 1001;
static final int REQUEST_CODE_RECOVER_FROM_AUTH_ERROR = 1002;
private static final String SCOPE ="oauth2:https://www.googleapis.com/auth/blogger";
private String mEmail; // Received from newChooseAccountIntent(); passed to getToken()
public ProgressDialog mDialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mDialog = new ProgressDialog(this);
    login();
}

public void login() {
    pickUserAccount();
}

private void pickUserAccount() {
    String[] accountTypes = new String[]{"com.google"};
    Intent intent = AccountPicker.newChooseAccountIntent(null, null, accountTypes, false, null, null, null, null);
    startActivityForResult(intent, REQUEST_CODE_PICK_ACCOUNT);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_CODE_PICK_ACCOUNT) {
        // Receiving a result from the AccountPicker
        if (resultCode == RESULT_OK) {
            mEmail = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);

            // With the account name acquired, go get the auth token
            getToken();
        } else if (resultCode == RESULT_CANCELED) {
            // The account picker dialog closed without selecting an account.
            // Notify users that they must pick an account to proceed.
            Toast.makeText(this, "Pick Account", Toast.LENGTH_SHORT).show();
        }

            && resultCode == RESULT_OK) {
        // Receiving a result that follows a GoogleAuthException, try auth again
        getToken();
    }

在这个问题上，我一直在用头撞墙。有人有什么想法吗？

终于明白了。

我的 build.gradle 文件以某种方式最终具有与我的 list 不同的应用程序 ID。我改变了它，使它们都与 list 相匹配，然后繁荣!它奏效了。
