Android：在没有Google API的Google帐户中使用OAuth2进行身份验证

Question

为了使用Google API之前必须在Google帐户中使用OAuth2获取身份验证令牌进行身份验证。 那么，我会知道是否有可能做相反的事情：在Android中使用OAuth2，我不通过Google API在Google帐户中进行身份验证。 我只需要在Google帐户中进行身份验证即可执行Google Apps脚本脚本，即仅针对这些脚本创建GET或POST参数化请求，这些脚本将根据其代码处理此参数，仅此而已。

是的，这是可能的。 代码做到这一点：

public class UploadFileGASActivity extends Activity { 
    public final static String GAS_HELLO_WORLD = "url_to_gas_script"; 
    public static boolean authTokenInvalidated = false; 

    public class OnTokenAdquired implements AccountManagerCallback<Bundle>{ 
     public void run(AccountManagerFuture<Bundle> future){ 
      Log.v("CALLBACK","post-getAuthToken"); 
      try { 
       Bundle authTokenBundle = future.getResult(); 

       if (authTokenBundle.containsKey(AccountManager.KEY_AUTHTOKEN)){ 
        String authTokenStr = authTokenBundle.getString(AccountManager.KEY_AUTHTOKEN); 
        String accountName = authTokenBundle.getString(AccountManager.KEY_ACCOUNT_NAME); 
        String accountType = authTokenBundle.getString(AccountManager.KEY_ACCOUNT_TYPE); 
        Log.v("ACCOUNT NAME",accountName); 
        Log.v("ACCOUNT TYPE",accountType); 
        Log.v("TOKEN",authTokenStr); 
        if (!authTokenInvalidated) { 
         invalidateAuthToken("com.google",authTokenStr); 
         authTokenInvalidated = true; 
         Log.v("CALLBACK","authTokenInvalidated == true"); 
         getAuthToken(); 
         return; 
        } 
        else { 
         authTokenInvalidated = false; 
         Log.v("CALLBACK","authTokenInvalidated == false"); 
        } 
        HttpUtil httpUtil = new HttpUtil(); 
        String responseStr = httpUtil.getResponseFromHttpRequest(GAS_HELLO_WORLD, authTokenStr); 
        Log.v("GAS_HELLO_WORLD",responseStr); 
        TextView textView = (TextView)findViewById(R.id.text_upload_file_gas); 
        textView.setText(authTokenStr); 
       } 
       else { 
        Log.v("KEY_AUTHTOKEN","non hai auth token, normal cando non hai conexion"); 
       } 
       if (authTokenBundle.containsKey(AccountManager.KEY_INTENT)) { 
        Log.e("KEY_INTENT","temos KEY_INTENT"); 
        Intent launch = (Intent)authTokenBundle.get(AccountManager.KEY_INTENT); 
        startActivityForResult(launch,0); 
        return; 
       } 
      } 
      catch (AuthenticatorException e){ 
       Log.e("OnTokenAdquired.run","AuthenticatorException"); 
      } 
      catch (IOException e){ 
       Log.e("OnTokenAdquired.run","IOException"); 
      } 
      catch (OperationCanceledException e){ 
       Log.e("OnTokenAdquired.run","OperationCanceledException"); 
      } 
     } 
    } 
    public void getAuthToken() { 
     AccountManager accountManager = AccountManager.get(this); 
     Bundle options = new Bundle(); 
     OnTokenAdquired onTokenAdquired = new OnTokenAdquired(); 
     Handler handler = new Handler(); 
     Account[] accounts = accountManager.getAccountsByType("com.google"); 
     String authTokenType = "oauth2:https://www.googleapis.com/auth/drive"; 
     AccountManagerFuture<Bundle> future = accountManager.getAuthToken(accounts[1], 
      authTokenType, options, this, onTokenAdquired, handler); 
    } 
    public void invalidateAuthToken(String accountType, String authToken){ 
     AccountManager accountManager = AccountManager.get(this); 
     accountManager.invalidateAuthToken(accountType, authToken); 
    } 

    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     //Activity.RESULT_OK; 
     Bundle extras = data.getExtras(); 
     Set<String> keys = extras.keySet(); 
     Iterator<String> iter = keys.iterator(); 
     Log.v("KEY_INTENT","requestCode: "+requestCode+", resultCode: "+resultCode); 
     Log.v("KEY_INTENT","EXTRAS KEY_INTENT"); 
     while (iter.hasNext()){ 
       Log.v("KEY_INTENT",(String)iter.next()); 
     } 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_upload_file_gas); 
      Log.v("GAS","UploadFileGASActivity called."); 
     getAuthToken(); 
    } 
} 

而且，在HttpUtil：

public String getResponseFromHttpRequest(String httpRequest, String authToken) { 
     [..] 
     request.setHeader("Authorization", "OAuth "+authToken); 
     [..] 
    } 

我希望它可以帮助别人。 无论如何，谢谢。
