}|code-block|syntax|javascript|704253|最后，我鼓励您在任何类型的后台线程(执行器、线程、异步任务等)中运行这段代码|704254|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

It basically depends on what you need, but assuming a simply POST request with a JSON body it'll look something like this (I'd suggest to use Apache HTTP Library).

<pre><code>HttpPost mRequest = new HttpPost(&lt;your url&gt;); 

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();
}
</code></pre>

Lastly, I'd encourage you to run this code in any kind of background thread (executor, thread, asynctask, etc)
