java - HttpClient.excute(HttpPost) no response

Question

I constructed an HttpClient, and set timeout parameters.

the code is like this:

while(bufferedinputstream.read()!=-1){

    post.setEntity(multipartEntity);
    HttpResponse response = httpClient.excute(post);
}

it worked fine for the first several request, and then somehow the response is not returned, and no exception or timeout exception was thrown. Anyone has any idea what's happening?

由于您没有收到任何错误或异常（您是否将它们打印出来？），您可以检查您的回复的 satusCode。也许它有帮助。

（我的 AsyncTask 中的重写方法）

protected String doInBackground(String... arg) {
    String url = arg[0]; // Added this line
    //...

    Log.i(DEBUG_TAG, "URL CALL -> " + url);

    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(url);

    String mResponse = "";
    try {

         List<NameValuePair> params = new LinkedList<NameValuePair>();
         //...

         post.setEntity(new UrlEncodedFormEntity(params));

        HttpResponse mHTTPResponse = client.execute(post);

        StatusLine statusLine = mHTTPResponse.getStatusLine();
        int statusCode = statusLine.getStatusCode();

        if (statusCode == 200) { // 

            //get response
            BufferedReader rd = new BufferedReader(new InputStreamReader(
                    mHTTPResponse.getEntity().getContent()));

            StringBuilder builder = new StringBuilder();
            String aux = "";

            while ((aux = rd.readLine()) != null) {
                builder.append(aux);
            }

            mResponse = builder.toString();

        } else {
            //cancel task and show error
            Log.e(DEBUG_TAG, "ERROR in Request:" + statusCode);
            this.cancel(true);
        }
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return mResponse;
}
