Java和Jquery Md5做接口签名

一：介绍

1 2	html与后端接口访问，为了简单的安全验证，需要做一下签名处理，一般是某一个字段+timestamp做md5的签名，后端比对签名是否一致。

二：html代码

代码块

<!DOCTYPE html>
<html lang="en">
 <head> 
  <meta charset="UTF-8" /> 
  <title>MD5签名</title> 
 </head> 
 <body> 
<script src="./jquery.js"></script>
<script src="./md5.js"></script>
<script type="text/javascript" >
	var userId = '0b44baa65b90727f015b9076a38a0001';
	var timestamp = '1558494714737'
	var t1 = userId + timestamp;
	var s1 = $.md5(t1);
	console.log(s1);
</script>
 </body>
</html>

md5.js

三：java代码

代码块

package com.tohours.tookeen.util;

import java.security.MessageDigest;

public class MD5Utils {
	private static String byteArrayToHexString(byte b[]) {  
        StringBuffer resultSb = new StringBuffer();  
        for (int i = 0; i < b.length; i++)  
            resultSb.append(byteToHexString(b[i]));  
  
        return resultSb.toString();  
    }  
  
    private static String byteToHexString(byte b) {  
        int n = b;  
        if (n < 0)  
            n += 256;  
        int d1 = n / 16;  
        int d2 = n % 16;  
        return hexDigits[d1] + hexDigits[d2];  
    }  
  
    public static String MD5Encode(String origin, String charsetname) {  
        String resultString = null;  
        try {  
            resultString = new String(origin);  
            MessageDigest md = MessageDigest.getInstance("MD5");  
            if (charsetname == null || "".equals(charsetname))  
                resultString = byteArrayToHexString(md.digest(resultString  
                        .getBytes()));  
            else  
                resultString = byteArrayToHexString(md.digest(resultString  
                        .getBytes(charsetname)));  
        } catch (Exception exception) {  
        }  
        return resultString;  
    }  
  
    private static final String hexDigits[] = { "0", "1", "2", "3", "4", "5",  
        "6", "7", "8", "9", "a", "b", "c", "d", "e", "f" };  
}
