HttpClient方式调用接口的java 简单案例源码+附jar包

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();
        }
    }
}
