我正在使用 GoogleUtilAuth.getToken() 生成 token 。我还生成了两个客户端 ID，一个用于网页，一个用于 Android 应用程序，两者都在同一个项目中。点击此链接

verification from back end server

这是我的代码:

package com.example.tokengenerate;

import java.io.IOException;

import com.google.android.gms.auth.GoogleAuthException;
import com.google.android.gms.auth.GoogleAuthUtil;
import com.google.android.gms.auth.UserRecoverableAuthException;

import android.widget.TextView;

public class MainActivity extends Activity {
    TextView tv;
    String scope="audience:server:client_id:CLIENTID OF WEBPAGE";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv =(TextView)findViewById(R.id.printId);
    new AsyncTask<Void, Void, Void>() {
        String id=null;
        @Override
        protected void onPostExecute(Void result) {
            // TODO Auto-generated method stub
            tv.setText(id);
            super.onPostExecute(result);
        }

        @Override
        protected Void doInBackground(Void... params) {
            // TODO Auto-generated method stub

                String[] account=getAccountNames();
                for(int i =0;i<account.length;i++)
                {
                    try {
                    Log.e("account name", account[i]);
                     id=GoogleAuthUtil.getToken(MainActivity.this, account[i], scope);
                        Log.e("google id",id);
                    } catch (UserRecoverableAuthException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (GoogleAuthException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }



            return null;
        }
    }.execute(null,null,null);


    }
    private String[] getAccountNames() {
      AccountManager  mAccountManager = AccountManager.get(this);
        Account[] accounts = mAccountManager.getAccountsByType(
                GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE);
        String[] names = new String[accounts.length];
        for (int i = 0; i < names.length; i++) {
            names[i] = accounts[i].name;
        }
        return names;
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

这是我的 Logcat:

完全卡住了，请帮忙。没明白我要去的地方

最佳答案

使用此代码获取范围

String scope = "oauth2:" + Scopes.PROFILE;

并在这里使用这个scpe

id=GoogleAuthUtil.getToken(MainActivity.this, account[i], scope);

然后你可以在变量“id”中获取你的访问 token 。简单方法。
