【问题描述】：

以下是我发布的代码，然后从 url 获取响应... 每当我运行代码时，我都没有在 Bufferedreader 中得到响应...

protected Void doInBackground(String... urls) {

    try{

    HttpClient httpclient = new DefaultHttpClient();

    HttpPost httppost = new HttpPost("http://www.indianrail.gov.in/pnr_Enq.html");

    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

     response = httpclient.execute(httppost);

    }catch(Exception e){

    Log.e("log_tag", "Error in http connection "+e.toString());

    }

    return null;

    }


protected void onPostExecute(Void unused) {

    Dialog.dismiss();
    HttpEntity httpEntity= response.getEntity();
    Toast.makeText(getApplicationContext(), "resp of :"+response.getEntity().getContentLength(), Toast.LENGTH_SHORT).show();

    try {
        Toast.makeText(getApplicationContext(), "in", Toast.LENGTH_SHORT).show();
        Toast.makeText(getApplicationContext(), ""+response.getEntity().getContentLength(), Toast.LENGTH_SHORT).show();
        in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        Toast.makeText(getApplicationContext(), "string creating :)",Toast.LENGTH_SHORT).show();
       Toast.makeText(getApplicationContext(), ""+line, Toast.LENGTH_SHORT).show();
    }  catch (Exception e) {
        // TODO Auto-generated catch block
        Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show();

        e.printStackTrace();
    }

我在 postExecute 方法中的 Bufferedreader 处收到错误... LogCat o/p如下

E/ActivityThread(611): Service com.android.exchange.ExchangeService has leaked ServiceConnection com.android.emailcommon.service.ServiceProxy$ProxyConnection@40cf4cf0 that was originally bound here

【问题讨论】：

响应声明在哪里？

标签： android entity http-post httprequest

【解决方案1】：

尝试以下方法：

如果您的响应是 json 格式，请按以下方式使用您的代码，然后使用来自 doInBackground(Void... params) 中的实体的“响应”：

DefaultHttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(serviceURL);                                   
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
HttpResponse response = client.execute(request);
HttpEntity entity = response.getEntity();

用错误回复你得到的结果..
