} // end onCreate()
public void callWebService(String q){
HttpClient httpclient = new DefaultHttpClient();
HttpGet request = new HttpGet(URL + q);
request.addHeader("deviceId", deviceId);
ResponseHandler<string> handler = new BasicResponseHandler();
try {
result = httpclient.execute(request, handler);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
httpclient.getConnectionManager().shutdown();
Log.i(tag, result);
} // end callWebService()

这基本上取决于您需要什么,但假设一个简单的带有 JSON 正文的 POST 请求,它看起来像这样(我建议使用 Apache HTTP 库)。
HttpPost mRequest = new HttpPost(<your url>);
DefaultHttpClient client = new DefaultHttpClient();
//In case you need cookies, you can store them with PersistenCookieStorage
client.setCookieStore(Application.cookieStore);
try {
HttpResponse response = client.execute(mRequest);
InputStream source = response.getEntity().getContent();
Reader reader = new InputStreamReader(source);
//GSON is one of the best alternatives for JSON parsing
Gson gson = new Gson();
User user = gson.fromJson(reader, User.class);
//At this point you can do whatever you need with your parsed object.
} catch (IOException e) {
mRequest.abort();
}
最后,我鼓励您在任何类型的后台线程(执行程序、线程、异步任务等)中运行此代码
