实现发送验证码的工程下载
1、我们打开这个工程，查看其中的代码
package com.ghj.test;import java.io.IOException;import java.util.Scanner;import com.ghj.tool.SMSUtils;/*** 测试验证码类短信*/public class CaptchaMsgTest {private static String mobile = "xxxxxxxxxxxx";/*** 短信内容：您的验证码为%s,10分钟内有效。*/@SuppressWarnings("resource")public static void main(String[] args) {if(SMSUtils.isMobile(mobile)){try {SMSUtils.sendCode(mobile,"3943633");//发送验证码} catch (IOException e) {e.printStackTrace();}}System.out.print("请输入您收到的短信验证码：");String code = new Scanner(System.in).next();try {if(SMSUtils.verifyCode(mobile, code)){//校验验证码System.out.println("验证码正确...");}else{System.out.println("验证码错误...");}} catch (IOException e) {e.printStackTrace();}}}
mobile属性可以改为你想要发送到的手机号码 sendCode方法中的第二个参数为验证码模板id 其中调用了smsutil中的sendcode方法来向手机发送验证码
package com.ghj.tool;import com.alibaba.fastjson.JSON;import org.apache.http.HttpResponse;import org.apache.http.NameValuePair;import org.apache.http.client.entity.UrlEncodedFormEntity;import org.apache.http.client.methods.HttpPost;import org.apache.http.impl.client.CloseableHttpClient;import org.apache.http.impl.client.HttpClients;import org.apache.http.message.BasicNameValuePair;import org.apache.http.util.EntityUtils;import java.io.IOException;import java.util.ArrayList;import java.util.Date;import java.util.List;import java.util.regex.Matcher;import java.util.regex.Pattern;/*** 短信相关的工具类*/public class SMSUtils {private static final String NONCE = "123456";private static final String APP_SECRET = "87ae5a14b7e3";private static final String APP_KEY = "c5e7dd7648b871180f53063cf1d3f869";/*** 检测手机号有效性* * @param mobile 手机号码* @return 是否有效*/public static final boolean isMobile(String mobile){Pattern pattern = pile("^((1[3578][0-9])|(14[57]))\\d{8}$");Matcher matcher = pattern.matcher(mobile);return matcher.matches();}/*** 验证码类短信，注意：该短信中验证码不能自己生成，由网易云帮我们生成* * @param mobile 手机号码* @param templateId 验证码模板ID* @return 是否发送成功*/public static final boolean sendCode(String mobile, String templateId) throws IOException {HttpPost httpPost = new HttpPost("ease.im/sms/sendcode.action");String currentTime = String.valueOf(new Date().getTime()/1000L);String checkSum = CheckSumBuilder.getCheckSum(APP_SECRET,NONCE,currentTime);//set headerhttpPost.setHeader("AppKey",APP_KEY);httpPost.setHeader("CurTime",currentTime);httpPost.setHeader("Nonce",NONCE);httpPost.setHeader("CheckSum",checkSum);httpPost.setHeader("Content-Type","application/x-www-form-urlencoded;charset=utf-8");//set dataList<NameValuePair> nameValuePairList = new ArrayList<NameValuePair>();nameValuePairList.add(new BasicNameValuePair("mobile",mobile));nameValuePairList.add(new BasicNameValuePair("templateid", templateId));httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairList,"utf-8"));//start requestCloseableHttpClient closeableHttpClient = HttpClients.createDefault();HttpResponse httpResponse = closeableHttpClient.execute(httpPost);String responseResult = EntityUtils.toString(httpResponse.getEntity(),"utf-8");System.out.println("responseResult:"+responseResult);String stateCode = JSON.parseObject(responseResult).getString("code");if(stateCode.equals("200")){return true;}return false;}/*** 判断用户输入验证码与网易云生成的验证码是否一致* * @param mobile 电话号码* @param code 发送到mobile上的短信*/public static final boolean verifyCode(String mobile, String code) throws IOException {HttpPost httpPost = new HttpPost("ease.im/sms/verifycode.action");String currentTime = String.valueOf(new Date().getTime()/1000L);String checkSum = CheckSumBuilder.getCheckSum(APP_SECRET,NONCE,currentTime);//set headerhttpPost.setHeader("AppKey",APP_KEY);httpPost.setHeader("CurTime",currentTime);httpPost.setHeader("Nonce",NONCE);httpPost.setHeader("CheckSum",checkSum);httpPost.setHeader("Content-Type","application/x-www-form-urlencoded;charset=utf-8");//set dataList<NameValuePair> nameValuePairList = new ArrayList<NameValuePair>();nameValuePairList.add(new BasicNameValuePair("code",code));nameValuePairList.add(new BasicNameValuePair("mobile",mobile));httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairList,"utf-8"));//start requestCloseableHttpClient closeableHttpClient = HttpClients.createDefault();HttpResponse httpResponse = closeableHttpClient.execute(httpPost);String responseResult = EntityUtils.toString(httpResponse.getEntity(),"utf-8");System.out.println("responseResult:"+responseResult);String stateCode = JSON.parseObject(responseResult).getString("code");if(stateCode.equals("200")){return true;}return false;}}
因为我们是通过网易的第三方验证码服务来实现，所以其中app_key和app_secret两个属性的值需要网易云提供
http://netease.im/sms我们登陆这个网站 注册账户并登陆
创建应用，创建完成后，在下面未开通的服务中找到短信并申请免费试用，在最上方找到appkey管理，点进去后就有app key和app secret，将这两个值复制到smsutil类中的属性，点击短信管理模板跳转后在点击验证码模板可以自定义短信格式，每个验证码模板都有对应的id，选择一个复制到第一个程序sendCode方法的第二个参数中。
此时运行上面的第一个程序，手机就能收到验证码了。
2、下面我们通过验证码来实现网页登陆功能
<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%><!DOCTYPE html><html><head><meta charset="UTF-8"><title>用户登陆</title><script type="text/javascript" src="./js/jquery-3.3.1.js"></script><script type="text/javascript" >function sendcode(){var ajaxObject={url:"./SendcodeServlet",type:"GET",data:"phonenumber="+document.getElementById("phonenumber").value,dataType:"text",success:function(data){}}$.ajax(ajaxObject);}function checkcode(){var ajaxObject={url:"./CheckcodeServlet",type:"GET",data:{phonenumber:document.getElementById("phonenumber").value,checkword:document.getElementById("checkword").value},dataType:"text",success:function(data){}}$.ajax(ajaxObject);}</script></head><body><input id="phonenumber" placeholder="请输入手机号" value="" /><br /><input id="checkword" placeholder="请输入验证码" value="" /><button onclick="sendcode()">发送验证码</button><br /><button onclick="checkcode()">提交</button></body></html>
这是登陆页面jsp的代码，其中有两个函数，分别来实现发送验证码和校验验证码
package com.xt.userinfo;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.xt.send_checkcode.tool.SMSUtils;/*** Servlet implementation class CheckServlet*/public class SendcodeServlet extends HttpServlet {private static final long serialVersionUID = 1L;protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {String mobile = request.getParameter("phonenumber");System.out.println(mobile);if(SMSUtils.isMobile(mobile)){try {SMSUtils.sendCode(mobile,"3953566");//发送验证码} catch (IOException e) {e.printStackTrace();}}}}
这是实现发送验证码的servlet，它获取到了登陆页面上的手机号，并调用smsutils中的sendCode方法将手机号传入，这样就能将验证码发送到手机了。
package com.xt.userinfo;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.xt.send_checkcode.tool.SMSUtils;/*** Servlet implementation class CheckcodeServlet*/public class CheckcodeServlet extends HttpServlet {private static final long serialVersionUID = 1L;protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {String code = request.getParameter("checkword");String mobile = request.getParameter("phonenumber");System.out.println(mobile);System.out.println(code);if(SMSUtils.verifyCode(mobile, code)) {System.out.println("success");request.getRequestDispatcher("/success.jsp").forward(request, response);}else {System.out.println("fail");request.getRequestDispatcher("/fail.jsp").forward(request, response);}}}
这是实现验证并登陆的servlet，它获取到页面上的手机号和你刚刚收到并输入的验证码，再调用smsutils中的verify方法并将这两个参数传入，如果返回true就会登陆成功
