我的Android應用中的Google雲端硬盤返回錯誤400

Question

我將跟蹤developers.google.com中有關Drive v2的所有信息，以便在Android API 15中構建一個簡單的應用程序，僅用於上傳txt文件。 在花費了許多時間之后，像為庫編寫正確的Java構建路徑（在我的情況下為1.11.0），啟用和設置Drive SDK，對客戶端ID的API訪問等，花了很多時間。我在本文中找到了一個不錯的示例Google雲端硬盤將錯誤400或403返回我的Android應用程序？ 在這里，我找到了與我上應用程序相同的錯誤描述。 這是我的完整代碼（希望對其他人有用）：

public class DrivexampleActivity extends Activity { 

Context activity = null;
boolean alreadyTriedAgain;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    AccountManager am = AccountManager.get(this);
    activity = this.getApplicationContext();
    Bundle options = new Bundle();
    Account[] acc = am.getAccounts();
    am.getAuthToken(
        (am.getAccounts())[8], // #8 just in my phone case. you can debugg the acc variable to find your @gmail account index.
        "oauth2:" + DriveScopes.DRIVE,
        options,
        true, 
        new OnTokenAcquired(),
        null); 
}

private class OnTokenAcquired implements AccountManagerCallback<Bundle> {
    @Override
    public void run(AccountManagerFuture<Bundle> result) {

        try {
            final String token = result.getResult().getString(AccountManager.KEY_AUTHTOKEN);

            HttpTransport httpTransport = new NetHttpTransport();
            JacksonFactory jsonFactory = new JacksonFactory();  

            Drive.Builder b = new Drive.Builder(httpTransport, jsonFactory, null);
            b.setJsonHttpRequestInitializer(new JsonHttpRequestInitializer() {
            @Override
            public void initialize(JsonHttpRequest request) throws IOException {
            // TODO Auto-generated method stub
                DriveRequest driveRequest = (DriveRequest) request;
                driveRequest.setPrettyPrint(true);                              
                driveRequest.setKey("xxxxxxxxxxxx.apps.googleusercontent.com"); // I replaced the number with x's. for your Client ID from Google API Console
                driveRequest.setOauthToken(token);                      
                }
            }); 

                final Drive drive = b.build();

                final com.google.api.services.drive.model.File body = new com.google.api.services.drive.model.File();
                body.setTitle("My Test File");
                body.setDescription("A Test File");
                body.setMimeType("text/plain");

                java.io.File fileContent = new java.io.File("document.txt");
                final FileContent mediaContent = new FileContent("text/plain",fileContent);

                new Thread(new Runnable() {
                    public void run() {

                        com.google.api.services.drive.model.File file;
                        try {                           
                            file = drive.files().insert(body, mediaContent).execute();
                            Log.i("Hi", "File ID: " + file.getId());
                            alreadyTriedAgain = false; // Global boolean to make sure you don't repeatedly try too many times when the server is down or your code is faulty... they'll block requests until the next day if you make 10 bad requests, I found.
                        } catch (IOException e) {
                            if(!alreadyTriedAgain){
                                alreadyTriedAgain = true;
                                Log.i("Hi", "The upload/insert was caught, which suggests it wasn't successful...");
                                e.printStackTrace();    
                            }    
                        }
                    }
                }).start();

                Intent launch = null;
                launch = (Intent)result.getResult().get(AccountManager.KEY_INTENT);

                if (launch != null) {
                    Log.i("Hi", "Something came back as a KEY_INTENT");
                    startActivityForResult(launch, 3025);
                    return; 
                }
        } catch (OperationCanceledException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (AuthenticatorException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }        
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 3025) {
        switch (resultCode) {
            case RESULT_OK:
                AccountManager am = AccountManager.get(activity);
                Bundle options = new Bundle();
                am.getAuthToken(
                        (am.getAccounts())[8], // #8 just in my phone case. you can debugg the acc variable to find your @gmail account index.
                        "oauth2:" + DriveScopes.DRIVE,
                        options,
                        true, 
                        new OnTokenAcquired(),
                        null); 
                break;
            case RESULT_CANCELED:
                // This probably means the user refused to log in. Explain to them why they need to log in.
                break;
            default:
                // This isn't expected... maybe just log whatever code was returned.
                break;
        }
    } else {
        // Your application has other intents that it fires off besides the one for Drive's log in if it ever reaches this spot. Handle it here however you'd like.
    }
}

同時體現：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.drivexample"
android:versionCode="1"
android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="14" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.USE_CREDENTIALS" />
    <uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />
    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity

            android:label="@string/app_name" 
            android:exported="true">
            <meta-data android:name="com.google.android.apps.drive.APP_ID" android:value="id=xxxxxxxxxxxx"/>

            <intent-filter>
                <action android:name="com.google.android.apps.drive.DRIVE_OPEN" />
                <data android:mimeType="application/vnd.test.type"/>
            </intent-filter>
        </activity>
    </application>

</manifest>

但是總會出現以下錯誤：

com.google.api.client.http.HttpResponseException: 400 Bad Request
{
  "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "keyInvalid",
    "message": "Bad Request"
   }
  ],
  "code": 400,
  "message": "Bad Request"
 }
}

在我看來，DRIVE SDK和Drive API沒有錯誤。 有什么建議嗎？ 請！！

Answer 1

您將從API控制台獲得的客戶端ID傳遞給driveRequest.setKey，但是該方法用於設置API密鑰而不是客戶端ID。 有關更多詳細信息，請檢查您提到的另一個問題的第一個答案。
