Question

我正在使用Drive REST Api（不是Google Drive Android API），当我向Google云端硬盘发送请求时，我经常会超时（+ - 每5个请求）。它可以在我列出文件夹或下载文件时出现，但仅在我发出请求时出现。从未下载过。

对于测试，我使用Wifi连接。没有问题的互联网连接。

我在文档（https://developers.google.com/drive/web/quickstart/android）中创建了类似描述的连接。这是代码：

googleAccountCredential = GoogleAccountCredential.usingOAuth2(activity, Arrays.asList(DriveScopes.DRIVE_FILE));

if (accountName.length() == 0) {
    activity.startActivityForResult(googleAccountCredential.newChooseAccountIntent(), ResultCode.GOOGLE_DRIVE_ACCOUNT_NAME_RESULT_CODE);
    return false;
} else {
    if (!isConnected) {
        googleAccountCredential.setSelectedAccountName(accountName);
        googleAccountCredential.setBackOff(new ExponentialBackOff());

        driveService = new Drive.Builder(AndroidHttp.newCompatibleTransport(), JacksonFactory.getDefaultInstance(), googleAccountCredential)
                .setApplicationName(activity.getString(R.string.app_name))
                .build();

        isConnected = true;
    }

    return true;
}

所以，如果我没有“帐户名”，我会问它，否则我只创建一次连接！（我每次尝试创建连接，但它不会改变任何东西）

所有请求都是在asyncTask中进行的。

有时它可以工作，有时候不工作。

请求超时例子：

1

request = driveService.files().list();
request.setQ("root in parents AND trashed = false");
fileList = request.execute();// Time-out

2

HttpResponse resp = driveService.getRequestFactory().buildGetRequest(new GenericUrl(url)).execute();// Time-out

这是转储：

有什么想法吗？

Answer 1

我的代码中没有看到任何明显不正确的内容，事实上，我已经成功使用了非常类似的构造：

  com.google.api.services.drive.Drive driveService =
    new Drive.Builder(
      AndroidHttp.newCompatibleTransport(),
      new GsonFactory(),
      GoogleAccountCredential
        .usingOAuth2(activity.getApplicationContext(), Collections.singletonList(DriveScopes.DRIVE_FILE))
        .setSelectedAccountName(accountName)
  ).build();

所以，让我们看看差异（不是说这是修复）：

1 /我没有指定'.setBackOff（new ExponentialBackOff（））'策略

2 /我使用'activity.getApplicationContext（）'而不是活动上下文

3 /我不知道您的用户电子邮件（accountName）来自哪里。它必须是在设备上注册的帐户之一，可以通过以下方式实现：

标准Android设置＆gt;帐户菜单＆gt;添加帐户
未指定'setSelectedAccountName（accountName）'，这会导致帐户选择器弹出，允许用户选择已注册的帐户或添加新帐户
在您的活动中调用帐户选择器并从'onActivityResult'

第3点很可能不会导致您的问题，它会返回不同的错误消息。

所有这一切都可以在RESTDemo here中看到（请参阅REST.init()和REQ_ACCPICK）。

祝你好运

对于其他有此问题的人，这对我有用：

    private static HttpRequestInitializer setHttpTimeout(final HttpRequestInitializer requestInitializer) {
            return new HttpRequestInitializer() {
                @Override
                public void initialize(HttpRequest httpRequest) throws IOException {
                    requestInitializer.initialize(httpRequest);
                    httpRequest.setConnectTimeout(3 * 60000);  // 3 minutes connect timeout
                    httpRequest.setReadTimeout(3 * 60000);  // 3 minutes read timeout
                }
            };
        }


 @Nullable
    public static DriveServiceHelper create(Context context) {

        Set<Scope> requiredScopes = new HashSet<>(2);
        requiredScopes.add(new Scope(DriveScopes.DRIVE_APPDATA));
        requiredScopes.add(new Scope(DriveScopes.DRIVE_FILE));

        GoogleSignInAccount signInAccount = GoogleSignIn.getLastSignedInAccount(context);
        if (signInAccount != null && signInAccount.getGrantedScopes().containsAll(requiredScopes)) {




            // Use the authenticated account to sign in to the Drive service.
            GoogleAccountCredential credential =
                    GoogleAccountCredential.usingOAuth2(context, Collections.singleton(DriveScopes.DRIVE_APPDATA));
            credential.setSelectedAccount(signInAccount.getAccount());
            com.google.api.services.drive.Drive googleDriveService =
                    new com.google.api.services.drive.Drive.Builder(
                            AndroidHttp.newCompatibleTransport(),
                            new GsonFactory(),
                            setHttpTimeout(credential))
                            .setApplicationName(context.getString(R.string.app_name))
                            .build();

            return new DriveServiceHelper(googleDriveService);
        }

        return null;
    }
