java - 没有像 postId 这样的 fb 我刚刚分享成功

Question

我已经从我的 Android 应用分享了一个 url 到 FB:

然后我将 postId 保存在一边(硬编码)

我尝试对那个帖子做“fb like”

使用这段代码，却报错:

Button socialBtn3 = (Button) dialog
                        .findViewById(R.id.socialBtn3);
                socialBtn3.setOnClickListener(new OnClickListener() {

                    String fbPostId = "685560152_10153809399380153";
                    @Override
                    public void onClick(View v) {

                        new LikeFbPostAsyncTask().execute(fbPostId);
                    }
                });

还有这个:

public class LikeFbPostAsyncTask extends AsyncTask<String, Void, Void> {

    public LikeFbPostAsyncTask() {
    }

    @Override
    protected void onPreExecute() {
        Log.i("LikeFbPostAsyncTask", "Starting web task...");
    }

    @Override
    protected Void doInBackground(String... fbPostId) {

        Request likeRequest = new Request(Session.getActiveSession(),
                fbPostId + "/likes", null, HttpMethod.POST,
                new Request.Callback() {

                    @Override
                    public void onCompleted(Response response) {
                        Log.i(TAG, response.toString());

                        // how to return to ui thread?
                        // return response;
                    }
                });
        Request.executeBatchAndWait(likeRequest);
        return null;

    }

    @Override
    protected void onPostExecute(Void res) {

    }
}

{Response: responseCode: 404, graphObject: null, error: {HttpStatus: 404, errorCode: 803, errorType: OAuthException, errorMessage: (#803) Some of the aliases you requested do not exist: [Ljava.lang.String;@4284cd10}, isFromCache:false}

我该如何解决这个问题？

Answer 1

您正在向 AsyncTask (String...) 发送一组字符串参数。从数组中提取所需的字符串时，您应该这样做:

    Request likeRequest = new Request(Session.getActiveSession(),
            fbPostId[0] + "/likes", null, HttpMethod.POST,
            new Request.Callback() {

代替:

Request likeRequest = new Request(Session.getActiveSession(),
        fbPostId + "/likes", null, HttpMethod.POST,
        new Request.Callback() {
