服务器端的谷歌访问令牌

Question

我使用应用程序，它必须连接到谷歌，获取accessToken并将其发送到服务器端。在服务器端，此令牌用于连接到gmail帐户并获取所有联系人。这是我的代码和平，我如何获得访问令牌：

private static final String SCOPE = "oauth2: https://www.googleapis.com/auth/userinfo.profile" +
        "                         https://www.googleapis.com/auth/userinfo.email" +
        "                         https://www.googleapis.com/auth/plus.login";
static final int REQUEST_CODE_PICK_ACCOUNT = 1000;
static final int REQUEST_CODE_RECOVER_FROM_AUTH_ERROR = 1001;
static final int REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR = 1002;
String mEmail;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_social_auth);
    pickUserAccount();
}
/** Starts an activity in Google Play Services so the user can pick an account */
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) {
        if (resultCode == RESULT_OK) {
            mEmail = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
            new AccessToken(this, mEmail, SCOPE).execute();
        } else if (resultCode == RESULT_CANCELED) {
            Toast.makeText(this, "You must pick an account", Toast.LENGTH_SHORT).show();
        }
    } else if ((requestCode == REQUEST_CODE_RECOVER_FROM_AUTH_ERROR ||
            requestCode == REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR)
            && resultCode == RESULT_OK) {
        handleAuthorizeResult(resultCode, data);
        return;
    }
    super.onActivityResult(requestCode, resultCode, data);
}

    if (data == null) {
        show("Unknown error, click the button again");

        Log.i(TAG, "Retrying");
        mEmail = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
        new AccessToken(this, mEmail, SCOPE).execute();
        return;
    }
    if (resultCode == RESULT_CANCELED) {
        show("User rejected authorization.");
        return;
    }
    show("Unknown error, click the button again");
}

服务器开发人员使用此 url 获取访问权限：https://www.googleapis.com/plus/v1/people/[id]/people/visible？access_token=[myAccessToken]但是在服务器端，我收到 403 错误：未配置访问权限。未为您的项目启用 API，或者您的 API 密钥上配置了每 IP 或每引用限制，并且请求与这些限制不匹配。请使用 Google 开发者控制台更新您的配置。

如果我仅使用 https://www.googleapis.com/auth/userinfo.profile 作为 SCOPE，我们会收到下一个错误："权限不足"

在开发者控制台中，我启用了联系人 API 和 Google+ API。

我想从 android 设计中获取有用的访问令牌，将其发送到服务器端，并从中获取用户联系人。我做错了什么？

您是否访问了 Google 开发人员控制台并为您的项目启用了Contacts API？
