短信验证码获取步骤详情!

一般在用户登陆时，都会选择手机号登录，这就难免要获取手机验证码，在前端页面设置获取验证码button, 点击后实现倒计时60s，并发送验证码设计结构：后台随机6位验证码将验证码存入session中, 调用第三方接口实现发送验证码 ,在后台取出session并和输入的验证码进行匹配,需要的jar包有：commons-codec-1.4.jar

commons-httpclient–3.1.jar

commons-loging-1.1.jar

index.jsp

第一步，写jsp

<%@ page language="java" contentType="text/html; charset=utf-8"

pageEncoding="utf-8"%>

<%@ page import="com.yzm.SMSUtil" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<title>Insert title here</title>

button {

background: #F0F0F0 repeat-x;

padding-top: 3px;

border-top : 1px solid #708090;

border-right: 1px solid #708090;

border-bottom: 1px solid #708090;

border-left: 1px solid #708090;

width: auto; line-height: 12pt;

font-size : 10pt; cursor: hand;

font-size: 10pt;

border-top: 1px solid #708090;

}

</style><script type="text/javascript">

var countdown=60;

var userphone=document.getElementById("userphone");

function settime(obj) {

if (countdown == 0) {

obj.removeAttribute("disabled");

obj.value="免费获取验证码";

countdown = 60;

return;

} else {

obj.setAttribute("disabled", true);

obj.value="重新发送(" + countdown + ")";

countdown--;

setTimeout(function() {

settime(obj) } ,1000)}}</script></head><body>

账户电话：<input type="text" name="userphone" id="userphone"><br>

<% String vcode="";

for(int i=0;i<6;i++){

vcode=vcode+(int)(Math.random()*9);

}

SMSUtil sms=new SMSUtil();

sms.sendSMS(vcode);

session.setAttribute("vcode", vcode);

System.out.println(vcode); %>

密码：<input type="password" name="password" id="password"><br>

输入验证码<input type="text" name="yzm" id="yzm"> <input type="submit" value="登录">

</form>

</body>

</html>

调用第三方接口发送短信信息

package com.yzm;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;

public class SMSUtil {

public void sendSMS(String vcode) {

try {

HttpClient client = new HttpClient();

PostMethod post = new PostMethod("http://gbk.sms.webchinese.cn");

post.addRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=gbk");

// uid：在中国网建网站上注册的用户id

// key:中国网建为注册用户提供的短信秘要

// smsMob：发送短信的手机号

// smsText:短信内容

NameValuePair[] data = { new NameValuePair("Uid", "用户名"),

new NameValuePair("Key", "秘钥"),

new NameValuePair("smsMob", "1882959****"),

new NameValuePair("smsText", "您的验证码为"+vcode) };

post.setRequestBody(data);

client.executeMethod(post);

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);

post.releaseConnection();

} catch (Exception ex) {

ex.printStackTrace();

}
