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();
}
}
