用户模块三（发送验证码的工具）

推荐使用：网建. http://sms.webchinese.com.cn/default.shtml

1.Maven导包

		<!--发送验证码核心jar包-->
        <!-- https://mvnrepository.com/artifact/commons-httpclient/commons-httpclient -->
        <dependency>
            <groupId>commons-httpclient</groupId>
            <artifactId>commons-httpclient</artifactId>
            <version>3.1</version>
        </dependency>

2.准备工具类 (官网也有)

package cn.itsource.pethome.basic.util;


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


import java.io.IOException;

public class SendMsgUtil {
    //本站用户名
    private static final String UID = "xiaoshigege";
    //接口安全密匙
    private static final String KEY = "d41d8cd98f00b204e980";

    public static void sendCode(String phone,String text){

        PostMethod post = null;
        //java也可以像网站一样发送请求
        try {
            //创建一个客户端
            HttpClient client = new HttpClient();
            //发送请求地址的url
            post = new PostMethod("http://utf8.api.smschinese.cn");
            //添加请求头信息
            post.addRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf8");//在头文件中设置转码
            //准备请求体
            NameValuePair[] data = {new NameValuePair("Uid", UID), new NameValuePair("Key", KEY), new NameValuePair("smsMob", phone), new NameValuePair("smsText", text)};
            //设置请求体
            post.setRequestBody(data);
            //发送请求
            client.executeMethod(post);

            //以下可不要
            Header[] headers = post.getResponseHeaders();
            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

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (post != null) {
            	//关闭资源
                post.releaseConnection();
            }
        }

    }

}

3.Java代码(Service层)

		//开始发送短信
        SendMsgUtil.sendCode(phone, text);
