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 = Pattern.compile("^((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

         * @return 是否发送成功
         */
        public static final boolean sendCode(String mobile, String templateId) throws IOException {
            HttpPost httpPost = new HttpPost("https://api.netease.im/sms/sendcode.action");
    
            String currentTime = String.valueOf(new Date().getTime()/1000L);
            String checkSum = CheckSumBuilder.getCheckSum(APP_SECRET,NONCE,currentTime);
    
            //set header
            httpPost.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 data
            List<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 request
            CloseableHttpClient 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("https://api.netease.im/sms/verifycode.action");
    
            String currentTime = String.valueOf(new Date().getTime()/1000L);
            String checkSum = CheckSumBuilder.getCheckSum(APP_SECRET,NONCE,currentTime);
    
            //set header
            httpPost.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 data
            List<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 request
            CloseableHttpClient 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][http_netease.im_sms] 我们登陆这个网站 注册账户并登陆  
![70][]  
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
