vue如何实现对请求参数进行签名

import axios from 'axios"
import {signatureGenerate} from "../utils/signatureUtil"

const request = new axios.create({
    timeout: 3000
})

// 请求拦截器
request.interceptors.request.use((config) => {

  // 获取请求头参数
  const {signature, timestamp, secret} = signatureGenerate(config)
  // 分别将签名、密钥、时间戳 至请求头 
  if(signature) config.headers["signature"] = signature
  if(secret) config.headers["key"] = secret
  if(timestamp) config.headers["timestamp"] = timestamp 
  // 这里未添加请求唯一id 各位可以自己实现以下，作者偷下懒 ~ ~
    
  return config
});

export default request

// signatureUtil.js
import md5 from "js-md5";
export function signatureGenerate({data, url, headers}){
    // 参数签名 密钥 + 时间戳 + header参数 + url

    // 密钥
    let secret = Math.random().toString(36).substr(2)
    // 时间戳
    let timestamp = new Date().getTime()     
    // token
    let token = headers.Authorization
    // post参数
    let dataStr = dataSerialize(dataSort(data))
    // 生成签名
    let str = dataStr + "secret=" + secret + "&timestamp=" + timestamp + "&url=" + url
    
    const sign = md5(str)
    
    return {
        signature: sign.toUpperCase(), // 将签名字母转为大写
        timestamp,
        secret
    }
}

// 参数排序
function dataSort(obj){
    if (JSON.stringify(obj) == "{}" || obj == null) {
        return {}
    }
    let key = Object.keys(obj)?.sort()
    let newObj = {}
    for (let i = 0; i < key.length; i++) {
        newObj[key[i]] = obj[key[i]]        
    }
    return newObj
}

// 参数序列化
function dataSerialize(sortObj){
    let strJoin = ''
    for(let key in sortObj){
        strJoin += key + "=" + sortObj[key] + "&"
    }

    // return strJoin.substring(0, strJoin.length - 1)
    return strJoin
}
