java 中国网建实现发送短信验证码

现在中国网建上注册一个自己的账户，

然后里面有代码案例，也有相应的下载jar包的地址

package com.direct.note;

import java.io.IOException;

import org.apache.commons.httpclient.Header;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.PostMethod;

public class Message {
	public static void main(String[] args) {
		try {
			new Message().sendMessage();
		} catch (HttpException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
	public void sendMessage() throws HttpException, IOException{
		HttpClient client = new HttpClient();
		PostMethod post = new PostMethod("http://gbk.api.smschinese.cn");
		//在头文件中设置转码
		post.addRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=gbk");
		int count = (int)(Math.random()*10000)+1;
		System.out.println(count);
		String message = "验证码："+count;
		NameValuePair[]  data = {
				new NameValuePair("Uid", "theStar"),
				new NameValuePair("Key", "你的key"),//73d1e45fd5f0fa2b9a87
				new NameValuePair("smsMob", "发送的电话号码"),
				new NameValuePair("smsText", message)
		};
		post.setRequestBody(data);
			client.executeMethod(post);
		Header[] headers = post.getRequestHeaders();
		int statusCode = post.getStatusCode();
		System.out.println("statusCode:   "+statusCode);
		for (Header h : headers) {
			System.out.println(h.toString());
		}
			String result=  new String(post.getResponseBodyAsString().getBytes("gbk"));
			System.out.println(result);//打印返回消息状态
		post.releaseConnection();
	}
