我想从我的 android 设备上使用 Google Storage。我启用了谷歌存储服务和谷歌存储 json api。我也启用了计费。

我从以下命令行获得了我的 SHA1 指纹：

keytool -list -v -keystore  ~/.android/debug.keystore

我在 api 控制台中设置了“SHA1 key;com.mydomain”，我得到了我的简单 API。

我正在尝试获取存储桶的内容，但遇到以下错误：

 com.google.api.client.googleapis.json.GoogleJsonResponseException: 401 Unauthorized

    "code" : 401,
    "errors" : [ {

    } ],

这是我的课：

    @EBean
public class GoogleCloudStorageImageImporter implements IImageImporter {

    public static final String TAG = "GoogleCloudStorageImageImporter";

    private static final String APPLICATION_NAME = "MyCompany-MyApp/1.0";

    private final JsonFactory JSON_FACTORY = new JacksonFactory();

    private HttpTransport transport = AndroidHttp.newCompatibleTransport();


    private GoogleCloudSettings settings;


    private Storage storage;

    @RootContext
    Activity activity;

    @RootContext
    Context context;


    @Bean(DefaultImageManager.class)
    IImageManager imageManager;

    @Bean(OrmliteRepositoryManager.class)
    ILocalRepository repository;

    Account account;

    GoogleAccountCredential credential;




    private void readSettings() {
        settings = GoogleCloudSettings.load(JSON_FACTORY,
                                            GoogleCloudSettings.class.getResourceAsStream("/foo_settings.json"));

        settings.setBucket("client-" + MainApplication.getBusinessId());

    }

    private Storage getStorageService() {

        StorageRequestInitializer storageRequestInitializer = new StorageRequestInitializer(ClientCredentials.API_KEY);

        return new Storage.Builder(transport,
                                    JSON_FACTORY,
                                    credential)
                                    .setApplicationName(APPLICATION_NAME)
                                    .setStorageRequestInitializer(storageRequestInitializer)
                                    .build();
    }


    public void doImport() {

        try {
            // settings
            readSettings();

            if( account == null) {
                GoogleAccountManager googleAccountManager = new GoogleAccountManager(activity);
                Account[] accounts = googleAccountManager.getAccountManager().getAccountsByType(GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE);
                account = accounts[2];
            }


            new BucketTask().execute(account);

        } catch (Throwable t) {
            Log.e(TAG, "Error while trying to import images from server",  t);
        }
    }

    private Bucket getBucket() {

        Log.i("Getting bucket " + settings.getBucket() + " metadata");
        Bucket bucket = null;
        try {
            Storage.Buckets.Get getBucket = storage.buckets().get(settings.getBucket());
            getBucket.setPrettyPrint(true);
            bucket = getBucket.execute();
            Log.i(bucket.toPrettyString());
        } catch (UserRecoverableAuthIOException e) {
            activity.startActivityForResult(e.getIntent(), StartupActivity.REQUEST_AUTHORIZATION);
        } catch (IOException e) {
            Log.e(TAG, "unable to get the bucket", e);
        }
        return bucket;

    }

    private class BucketTask extends AsyncTask<Account, Void, Bucket> {
        @Override
        protected Bucket doInBackground(Account... params) {



            try {

                if(credential == null) {
                    Account account = params[0];
                    credential = GoogleAccountCredential.usingOAuth2(activity, Collections.singleton(StorageScopes.DEVSTORAGE_READ_ONLY));
                    credential.setSelectedAccountName(account.name);
                }

                if( storage == null && credential != null) {
                    storage = getStorageService();
                }

                return getBucket();


        } catch (Throwable t) {
                Log.e(TAG, "Error while trying to import images from server", t);
            }
            return null;
        }

         @Override
        protected void onPostExecute(Bucket result) {
            //Do something with result
            if (result != null)
                result.getId();
        }
    }
}

我遵循了Drive示例。

有什么建议吗？

我发现了这个问题。

不要使用来自 API 控制台的简单 API 访问，但您必须为已安装的应用程序设置客户端 ID（请参阅上面的 Drive SDK 链接）

所以而不是：

private Storage getStorageService() {

        StorageRequestInitializer storageRequestInitializer = new StorageRequestInitializer(ClientCredentials.API_KEY);

        return new Storage.Builder(transport,
                                    JSON_FACTORY,
                                    credential)
                                    .setApplicationName(APPLICATION_NAME)
                                    .setStorageRequestInitializer(storageRequestInitializer)
                                    .build();
    }

你应该像这样使用它：

private Storage getStorageService() {

        return new Storage.Builder(transport,
                                    JSON_FACTORY,
                                    credential)
                                    .setApplicationName(APPLICATION_NAME)
                                    .build();
    }

希望有帮助！
