使用Android发送HTTP发布请求

您可以使用来自Apache Commons的Http Client。例如：

private class PostTask extends AsyncTask<String, String, String> {  @Override  protected String doInBackground(String... data) {    // Create a new HttpClient and Post Header    HttpClient httpclient = new DefaultHttpClient();    HttpPost httppost = new HttpPost("http://<ip address>:3000");    try {      //add data      List<NamevaluePair> namevaluePairs = new ArrayList<NamevaluePair>(1);      namevaluePairs.add(new BasicNamevaluePair("data", data[0]));      httppost.setEntity(new UrlEnpredFormEntity(namevaluePairs));      //execute http post      HttpResponse response = httpclient.execute(httppost);    } catch (ClientProtocolException e) {    } catch (IOException e) {    }  }}

更新

您可以使用Volley
Android网络库发布数据。正式文件在这里。

我个人将Android Asynchronous Http Client用于少数REST Client项目。

值得探索的其他工具是Retrofit。
