HttpClient方式调用接口的java 简单案例源码+附jar包

1 package com.itNoob.httpClient;
 2 
 3 import org.apache.commons.httpclient.HttpClient;
 4 import org.apache.commons.httpclient.methods.PostMethod;
 5 import org.apache.commons.httpclient.params.HttpMethodParams;
 6 
 7 public class HTTPClient {
 8 
 9     public static void main(String[] args) {
10         // 请求接口地址
11         String url = "http://v.juhe.cn/historyWeather/province";
12         // 请求参数
13         String key = "c60f89ced863679ebe086b9971b38957";
14 
15         HttpClient httpclient = null;
16         PostMethod post = null;
17         try {
18             // 创建连接
19             httpclient = new HttpClient();
20             post = new PostMethod(url);
21             // 设置编码方式
22             post.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
23             // 添加参数
24             post.addParameter("key", key);
25             // 执行请求
26             httpclient.executeMethod(post);
27             // 接口返回信息
28             String info = new String(post.getResponseBody(), "UTF-8");
29             System.out.println("resultJSON:" + info);
30         } catch (Exception e) {
31             e.printStackTrace();
32         } finally {
33             // 关闭连接，释放资源
34             post.releaseConnection();
35         }
36     }
37 }
