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
     * @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("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 我们登陆这个网站注册账户并登陆

java手机验证码发送 java实现发送手机验证码_java

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
