android最原始的网络请求(HttpClient)

eclipse可能需要org.apache.http.legacy.jar，该jar包在sdk/platforms/android-xx(您所安装的最高的sdk版本)/optional目录下可以找到

 1 // 网络访问请求
 2 new Thread(new Runnable() {
 3
 4     @Override
 5     public void run() {
 6
 7         String url = "";
 8         // 创建httpCient
 9         HttpClient client = new DefaultHttpClient();
10
11         // 创建post请求
12         HttpPost post = new HttpPost(url);
13         List<NameValuePair> pairs = new ArrayList<NameValuePair>();
14         // 配置请求头
15         post.addHeader("", "");
16
17         // 配置请求参数
18         pairs.add(new BasicNameValuePair("", ""));
19         pairs.add(new BasicNameValuePair("", ""));
20
21         try {
22             post.setEntity(new UrlEncodedFormEntity(pairs));
23             HttpResponse response = client.execute(post);
24
25             int statusCode = response.getStatusLine().getStatusCode();
26             if (statusCode == 200) {
27                 // 拿到网络的返回结果
28                 String result = EntityUtils.toString(response.getEntity());
29
30                 // 需要在主线程中进行UI操作
31                 Toast.makeText(context, result, Toast.LENGTH_SHORT).show();
32             }
33         } catch (Exception e) {
34             // TODO: handle exception
35         }
36     }
37 }).start();
