實現傳送驗證碼的工程下載

1、我們開啟這個工程，檢視其中的程式碼

package com.ghj.test;

import java.io.IOException;
import java.util.Scanner;

import com.ghj.tool.SMSUtils;

/**
 * 測試驗證碼類簡訊
 */
public class CaptchaMsgTest {
	
	private static String mobile = "xxxxxxxxxxxx";
	
	/**
	 * 簡訊內容：您的驗證碼為%s,10分鐘內有效。
	 */
	@SuppressWarnings("resource")
	public static void main(String[] args) {
		if(SMSUtils.isMobile(mobile)){
			try {
				SMSUtils.sendCode(mobile,"3943633");//傳送驗證碼
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
		System.out.print("請輸入您收到的簡訊驗證碼：");
		String code = new Scanner(System.in).next();
		try {
			if(SMSUtils.verifyCode(mobile, code)){//校驗驗證碼
				System.out.println("驗證碼正確...");
			}else{
				System.out.println("驗證碼錯誤...");
			}
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}
 

mobile屬性可以改為你想要傳送到的手機號碼 sendCode方法中的第二個引數為驗證碼模板id   其中呼叫了smsutil中的sendcode方法來向手機發送驗證碼

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;

    private static final String APP_KEY = "c5e7dd7648b871180f53063cf1d3f869";

    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();
    }
    
    /**

     */
    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;
        }

    }

    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

        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;
    }
    
   
    
   
}
 

因為我們是通過網易的第三方驗證碼服務來實現，所以其中app_key和app_secret兩個屬性的值需要網易雲提供
http://netease.im/sms 我們登陸這個網站 註冊賬戶並登陸

建立應用，建立完成後，在下面未開通的服務中找到簡訊並申請免費試用，在最上方找到appkey管理，點進去後就有app key和app secret，將這兩個值複製到smsutil類中的屬性，點選簡訊管理模板跳轉後在點選驗證碼模板可以自定義簡訊格式，每個驗證碼模板都有對應的id，選擇一個複製到第一個程式sendCode方法的第二個引數中。

此時執行上面的第一個程式，手機就能收到驗證碼了。

2、下面我們通過驗證碼來實現網頁登陸功能
 

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title>使用者登陸</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="請輸入手機號" value="" /><br />
			<input  id="checkword" placeholder="請輸入驗證碼" value="" />
			<button  onclick="sendcode()">傳送驗證碼</button><br />
			<button  onclick="checkcode()">提交</button>
	</body>
</html>

這是登陸頁面jsp的程式碼，其中有兩個函式，分別來實現傳送驗證碼和校驗驗證碼

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");//傳送驗證碼
			} catch (IOException e) {
				e.printStackTrace();
			}
		}

	}


}

這是實現傳送驗證碼的servlet，它獲取到了登陸頁面上的手機號，並呼叫smsutils中的sendCode方法將手機號傳入，這樣就能將驗證碼傳送到手機了。

 

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);
		}
	}


}

這是實現驗證並登陸的servlet，它獲取到頁面上的手機號和你剛剛收到並輸入的驗證碼，再呼叫smsutils中的verify方法並將這兩個引數傳入，如果返回true就會登陸成功
