HttpClient——Post请求

//为以下拼接请求地址
public String path="";
public String key="";
public String pno="";
public String ps="";
try {
// 创建客户端

HttpClient client = new DefaultHttpClient();

// 创建post对象

HttpPost post = new HttpPost(path);

ArrayList<BasicNameValuePair> list = new ArrayList<BasicNameValuePair>();
list.add(new BasicNameValuePair("key", key));
list.add(new BasicNameValuePair("pno", pno));
list.add(new BasicNameValuePair("ps", ps));

HttpEntity entity = new UrlEncodedFormEntity(list);

// 发送内容
post.setEntity(entity);
// 发送请求
HttpResponse response = client.execute(post);
//得到请求码
int statusCode = response.getStatusLine().getStatusCode();

if (statusCode == 200)

// 得到实体内容

//handler向主线程发送信息，更新数据
