Js 之Api接口验签

插件：https://underscorejs.net/

建议：单独创建一个js配置文件存放token，然后加密该文件。

一、前端

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>接口验签</title>
</head>
<body>
<script src="jquery.min.js"></script>
<script src="underscore-min.js"></script>
<script src="md5.js"></script>
<script>
    var url = './test.php?action=login&m=a&c=user&i=2';
    var params = getQuery(url);
    var token = 'Yang';
    params = _.sortBy(params, 'name');
    params = _.uniq(params, true, 'name');
    console.log(params)
    var sign = getSign(params, token);
    $.get(url+'&sign='+sign, function (res) {

    })
    /**
     * 获取url所有参数
     * @param url
     * @returns {Array}
     */
    function getQuery (url) {
        var theRequest = [];
        if (url.indexOf("?") != -1) {
            var str = url.split('?')[1];
            var strs = str.split("&");
            for (var i = 0; i < strs.length; i++) {
                if (strs[i].split("=")[0] && unescape(strs[i].split("=")[1])) {
                    theRequest[i] = {
                        'name': strs[i].split("=")[0],
                        'value': unescape(strs[i].split("=")[1])
                    }
                }
            }
        }
        return theRequest;
    }

    /**
     * 获取sign
     * @param params
     * @param token
     * @returns {*}
     */
    function getSign(params, token) {
        var urlData = '';
        for (let i = 0; i < params.length; i++) {
            if (params[i] && params[i].name && params[i].value) {
                urlData += params[i].name + '=' + params[i].value + '&';
            }
        }
        return md5(urlData + token);
    }
</script>
</body>
</html>

二、后端

/**
 * Created by PhpStorm.
 * User: Mr.Yang
 * Date: 2020/9/11
 * Time: 14:40
 * QQ: 2575404985
 */

$token = 'Yang';

$result = checkSign();

var_dump($result);

function checkSign()
{
    global $_GET, $token;
    if (!empty($_GET) && !empty($_GET['sign'])) {
        foreach ($_GET as $key => $get_value) {
            if ('sign' != $key && $get_value != '') {
                $sign_list[$key] = $get_value;
            }
        }
        ksort($sign_list);
        $sign = http_build_query($sign_list, '', '&') . '&' . $token;
        $sign = urldecode($sign);
        return md5($sign) == $_GET['sign'];
    }
    return false;
}
