Android Facebook SDK 4.4.1 - ShareApi.share(...) 发出 3 个请求

Question

今天我将我们的 Android Facebook SDK 更新到最新版本 (4.4.1)。我现在看到一些奇怪的行为。

当我打电话时：

ShareApi.share(contentForSharing(), shareCallback);

我看到三个请求。第一个成功：

[{Response:  responseCode: 200, graphObject: {"id":"552185138255521"}, error: null}]

第二次失败：

[{Response:  responseCode: 500, graphObject: null, error: {HttpStatus: 500, errorCode: 100, errorType: FacebookApiException, errorMessage: Invalid parameter}}]

第三次成功：

[{Response:  responseCode: 200, graphObject: {"success":true}, error: null}]

此外，图表故事出现在我的 Activity 日志中，显示完全符合预期，但没有出现在我的个人资料或主页供稿页面上。

还有其他人运行参与其中吗？

这是我的发布代码：

private void publishToFacebook() {
    ShareApi.share(contentForSharing(), shareCallback);
}

...内容构建者：

private ShareOpenGraphContent contentForSharing() {
    String previewPropertyName = "MyApp:MyObject";
    ShareOpenGraphAction.Builder actionBuilder = new ShareOpenGraphAction.Builder().setActionType("MyApp:MyAction");
    ShareOpenGraphObject fbObject = buildGraphObject();

    actionBuilder.putObject(previewPropertyName, fbObject);
    actionBuilder.putString("fb:explicitly_shared", "true");

    ShareOpenGraphContent.Builder contentBuilder =
            new ShareOpenGraphContent.Builder()
            .setAction(actionBuilder.build())
            .setPreviewPropertyName(previewPropertyName);

    return contentBuilder.build();
}

...对象生成器

private ShareOpenGraphObject buildGraphObject() {
    if (mLocalObject!=null) {
        Object[] urlArgs = 
                new Object[] {  
                "MyApp:MyObject",
                mLocalObject.getScore(),
                mLocalObject.getTitle(),
                mLocalObject.getDescription(),
                mLocalObject.getSummary() };
        String url = String.format("http://www.myappwebsite.com/obj.php?"+
                                    "fb:app_id=xxxxxxxxxxxx&og:type=%s"+
                                    "&MyApp:score=%s"+
                                    "&og:title=%s"+
                                    "&og:description=%s"+
                                    "&og:image=http://www.myappwebsite.com/images/icon.png"+
                                    "&body=%s", urlArgs);

        ShareOpenGraphObject obj = new ShareOpenGraphObject.Builder()
        .putString("og:type", "MyApp:MyObject")
        .putString("og:image", "http://www.myappwebsite.com/images/icon.png")
        .putString("og:image:width", "100")
        .putString("og:image:height", "100")
        .putString("og:title", mLocalObject.getTitle())
        .putString("MyApp:score", mLocalObject.getScore())
        .putString("og:description", mLocalObject.getDescription())
        .putString("og:url", url).build();
        return obj;
    }
    return null;
}

...响应回调：

private FacebookCallback<Sharer.Result> shareCallback =
        new FacebookCallback<Sharer.Result>() {
            @Override
            public void onCancel() {
                dismissProgressDialog();
            }

            @Override
            public void onError(FacebookException error) {
                if (error instanceof FacebookGraphResponseException) {
                    Timber.d("an error occurred posting to facebook");
                    FacebookGraphResponseException graphError =
                            (FacebookGraphResponseException) error;
                    if (graphError.getGraphResponse() != null) {
                        handleFacebookError(graphError.getGraphResponse());
                        return;
                    }
                }
               dismissProgressDialog();
            }

            @Override
            public void onSuccess(Sharer.Result result) {
                if (getActivity() == null) {
                    Timber.d("ACTIVITY IS NULL");
                    // if the user removes the app from the website,
                    // then a request will have caused the session to 
                    // close (since the token is no longer valid),
                    // which means the splash fragment will be shown 
                    // rather than this one, causing activity to be null. 
                    // If the activity is null, then we cannot
                    // show any dialogs, so we return.
                    return;
                }

               dismissProgressDialog();
               Toast.makeText(getActivity(), getResources().getString(R.string.success), Toast.LENGTH_SHORT).show();
               getActivity().finish();
            }
        };

...最后是错误处理程序

 private void handleFacebookError(GraphResponse response) {
     FacebookRequestError error = null;
     if (response!=null) {
         error = response.getError();
     }
     DialogInterface.OnClickListener listener = null;
     String dialogBody = null;

     if (error == null) {
         dialogBody = getString(R.string.error_dialog_default_text);
     } else {
         switch (error.getCategory()) {
         case LOGIN_RECOVERABLE:
             // There is a login issue that can be resolved by the LoginManager.
             LoginManager.getInstance().resolveError(this, response);
             return;
         case TRANSIENT:
             dialogBody = getString(R.string.fb_error_transient);
             break;

         case OTHER:
         default:
            // an unknown issue occurred, this could be a code error, or
            // a server side issue, log the issue, and either ask the
            // user to retry, or file a bug
            dialogBody = getString(R.string.fb_error_unknown, error.getErrorMessage());
            break;
         }
     }

     String title = error.getErrorUserTitle();
     String message = error.getErrorUserMessage();
     if (message == null) {
         message = dialogBody;
     }
     if (title == null) {
         title = getResources().getString(R.string.fb_error_dialog_title);
     }

     new AlertDialog.Builder(getActivity())
     .setPositiveButton(R.string.fb_error_dialog_button_text, listener)
     .setTitle(title)
     .setMessage(message)
     .show();
}

请注意，我使用的所有参数均已批准且有效（即 fb:explicitly_shared，消息），并且我已检查我的发布方法在整个过程中仅被调用一次。

Answer 1

我成功了；我不是很懂，但是我懂了。

请注意，在 'contentBuilder' 函数中，我将对象声明为 "MyApp:MyObject"，这是在我们的 iOS 应用程序中声明图形对象的方式。好吧，这在 Android 中不起作用。该对象仅使用 "MyObject" 声明...同样，我真的不明白这是为什么，但现在它正在工作。
