Question

我写了以下代码。

public void postSMS(String type,String phone,String body) 
    {
        //----------------------postSMS-------------------------------
                // Create a new HttpClient and Post Header
                    HttpClient httpclient = new DefaultHttpClient();
                    HttpPost httppost = new HttpPost("http://192.168.15.105:6543/data_in");

                    try {
                        // Add your data

                        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
                        nameValuePairs.add(new BasicNameValuePair("type", type));
                        nameValuePairs.add(new BasicNameValuePair("body", body));
                        nameValuePairs.add(new BasicNameValuePair("toRfrom", phone));
                        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                        // Execute HTTP Post Request
                        //HttpResponse response = httpclient.execute(httppost);
                        ResponseHandler<String> responseHandler=new BasicResponseHandler(); 
                        String responseBody = httpclient.execute(httppost, responseHandler); 
                        JSONObject response=new JSONObject(responseBody); 
                    } 
                    catch (ClientProtocolException e) {
                        // TODO Auto-generated catch block
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                    } catch (JSONException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
    }

错误是什么以及如何解决？由于我的服务器工作正常，但它是不发送数据的客户端。（我在服务器上使用python的PYCK框架。）

更新是的，我在清单中添加了INTERNET权限......

以下是错误日志：

Answer 1

1-如何通过端口6543发送数据。

解决方案很简单。将您的地址更改为以下

HttpPost httppost = new HttpPost("http://192.168.15.105:6543/data_in");

2-您的代码有任何错误吗？

我测试了你的代码，没有问题。所以，如果你的服务器发送有效的json字符串，那就应该没问题。

Answer 2

<强> android.os.NetworkOnMainThreadException 这就是问题所在。

您需要在后台线程上运行使用Internet的所有内容。

你可以使用AsyncTask，runnable或者只是创建一个新线程，最好的方法肯定是第一个。

httpClient不发送数据？
