方式一 :Postman脚本的方式生成v1版本的认证字符串
Postman脚本下载
下载Postman pre-request Script 设置 Authorization 示例脚本
方式二:在线签名工具生成 (试用于验证编程字符串签名是否有错误)
签名计算工具 https://cloud.baidu.com/signature/index.html
百度智能云提供了在线生成签名工具,用户仅需填写必要请求信息、访问密钥(包含访问密钥ID(AK)和秘密访问密钥(SK)),可快速生成认证字符串。
方式三 编程生成认证字符串(适合最终集成自己系统)

// robotList.js
// npm install crypto axios
const crypto = require('crypto');
const axios = require('axios');
const url = require('url');
const util = require('util');

// 5).1生成Canonical URL

// 6).生成signing Key
// 生成signingKey
const signingKey = crypto

.update(authStringPrefix)

// 生成Signature
const signature = crypto

// 8).生成Authorization并放到header里
headers['Authorization'] = `${authStringPrefix}/${signedHeaders}/${signature}`;
console.log(headers['Authorization']);
// 9).发送API请求并接受响应
// 发送 Axios 请求
axios
