HttpClient方式调用接口的java 简单案例源码+附jar包

1 package com.itNoob.httpClient;

 import org.apache.commons.httpclient.HttpClient;
 import org.apache.commons.httpclient.methods.PostMethod;
 import org.apache.commons.httpclient.params.HttpMethodParams;

 public class HTTPClient {

     public static void main(String[] args) {
         // 请求接口地址
         String url = "http://v.juhe.cn/historyWeather/province";
         // 请求参数
         String key = "c60f89ced863679ebe086b9971b38957";

         HttpClient httpclient = null;
         PostMethod post = null;
         try {
             // 创建连接
             httpclient = new HttpClient();
             post = new PostMethod(url);
             // 设置编码方式
             post.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
             // 添加参数
             post.addParameter("key", key);
             // 执行请求
             httpclient.executeMethod(post);
             // 接口返回信息
             String info = new String(post.getResponseBody(), "UTF-8");
             System.out.println("resultJSON:" + info);
         } catch (Exception e) {
             e.printStackTrace();
         } finally {
             // 关闭连接，释放资源
             post.releaseConnection();
         }
     }
 }
