h5请求签名加密

签名说明

  • 签名对 url + method + 业务参数 进行统一签名,防止重放和篡改
  • 客户端js对加密逻辑和appSecret进行混淆加密处理,增加破解难度
  • 客户端本地存储appid 和 appSecret 字段名,使用无意义字段,比如:nihao,wohao,dajiahao
  • 文件上传接口不进行签名,后期统一处理,签文件md5值。

名词解释:

  • appid: 统一分配的唯一标示 ,比如 ximaiwu_h5
  • nonce 随机字符串,每次重新生成,位数32位以上,推荐使用随机数+本地唯一值+用户唯一值参与计算
  • timestamp: 当前的时间戳 (10位时间戳,单位是秒)
  • signature: 最后生成的签名字符串

重要数据

  • appSecret: 统一分配的与唯一标示配对的密钥, 比如 E8yUMwLTOJWvdCsDuwIMup7R1dyxIHcE, 加密保存,不能泄露,不能在接口参数中传递
// 加密处理函数 返回处理过的请求数据

var Jia_Mi = function (obj, url, method) {
    var Url = url //接口地址
    var $method = method; //请求方式

    var arr = []
    //对象转数组处理
    for (let v in obj) {
        arr.push({
            key: v,
            value: obj[v]
        })
    }
    // console.log('arr', JSON.stringify(arr, null, 2));
    //首字母排序,生成一个按key首字母排序的升序数组
    arr.sort(function (s, t) {
        var a = s.key.toLowerCase();
        var b = t.key.toLowerCase();
        if (a < b) return -1;
        if (a > b) return 1;
        return 0;
    })
    console.log(arr, 2222)

    //使用 & 符号,将所有 key 和 value 连接起来, 
    var arrstr = Url + $method
    for (var i in arr) {  //遍历数组
        arrstr += arr[i].key + '=' + arr[i].value + "&"
    }
    // arr.forEach(function (e) {
    //     arrstr += e.key + '=' + e.value + "&"
    // })
    //使用 RFC 3986 编码格式的 urlencode , 将字符串统一编码
    arrstr = arrstr.slice(0, -1)
    console.log(arrstr, 22223333)
    arrstr = rawurlencode(arrstr);
    $appSecret = 'E8yUMwLTOJWvdCsDuwIMup7R1dyxIHcE'; //密钥,严格保存,字段名称无意义,混淆使用过程,跟appid 是配对使用的,不要在接口参数中传输
    //使用算法
    var sha1_result = CryptoJS.HmacSHA1(arrstr, $appSecret).toString(CryptoJS.enc.Base64); //第一个参数为加密字符串,第二个参数为公共秘钥
    console.log(sha1_result, 44444, )

/**
 * 生成uuid
 * 
 * UUid: 通用唯一识别码(Universally Unique Identifier)的缩写,是一种软件建构的标准,亦为开放软件
 * 基金会组织在分布式计算环境领域的一部分。其目的,是让分布式系统中的所有元素,都能有唯一的辨识信息,
 * 而不需要通过中央控制端来做辨识信息的指定。如此一来,每个人都可以创建不与其它人冲突的UUID。在这样的情
 * 况下,就不需考虑数据库创建时的名称重复问题。目前最广泛应用的UUID,是微软公司的全局唯一标识符(GUID)
 * ,而其他重要的应用,则有Linux ext2/ext3文件系统、LUKS加密分区、GNOME、KDE、Mac OS X等等。另外我们
 * 也可以在e2fsprogs包中的UUID库找到实现。
 *  UUID是由一组32个16进制数字所构成,因此UUID理论上的总数为:3.4*10^38,也就是说若每纳秒产生1兆个uuid,
 *  需要花100亿年才能用完所有的uuid,所以它是唯一的,不必担心重复。
 * 在JavaScript中生成uuid的代码如下,这个函数会直接给你返回uuid,所以直接调用,然后用变量接收即可!
