前端请求时加一个密钥的超详细方法_前端get请求参数base64加密怎么生成密钥

import axios from 'axios';
import { Base64 } from 'js-base64';
let md5 = require('js-md5');
const access_key = '{access_key}';  // 服务端生成的 access_key
const secret_key = '{secret_key}';  // 服务端生成的 secret_key
 
const timestamp = Date.parse(new Date()) / 1000;    // 取时间戳
const randomStr = (len) => {
	let str = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
	 let result = "";
	while(len) {
		let index = Math.floor(Math.random() * str.length);
		result += str[index];
		--len;
		
	}
	return result;
	
}
 
const echostr = randomStr(8);      // 随机字符串自行生成
 
const header = Base64.encode(JSON.stringify({
                   "alg": "md5",
                   "type": "jwt"
               }));
const payload = Base64.encode(JSON.stringify({
                 "timestamp": timestamp,
                 "echostr": echostr,
                 "ak": access_key
             }));
const signature_string = header  + '.' + payload;
 
function md5Sign(string, secret){
    return md5(string + secret);    // md5 库自行引入
}
 
const api_token = signature_string + '.' + md5Sign(signature_string,secret_key);
 
const requestConfig = {
    headers: {
        "api-token": api_token
    }
};
 
//请求时
axios.post('/api/example',{},requestConfig).then(res=>{
    // todo
});
