Node.js环境调用百度智能云(百度云)api鉴权认证三步走

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)

你可以运行下面的命令来安装所有依赖：

npm install crypto axios

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

function getUTC() {
  const date = new Date();

  const year = date.getUTCFullYear();
  const month = String(date.getUTCMonth() + 1).padStart(2, '0');
  const day = String(date.getUTCDate()).padStart(2, '0');
  const hours = String(date.getUTCHours()).padStart(2, '0');
  const minutes = String(date.getUTCMinutes()).padStart(2, '0');
  const seconds = String(date.getUTCSeconds()).padStart(2, '0');

  return `${year}-${month}-${day}T${hours}:${minutes}:${seconds}Z`;
}
function generateCanonicalUri(urlString) {
  let parsedUrl = url.parse(urlString, true);
  return parsedUrl.path;
}

function main() {
  //  1).AK/SK、host、method、URL绝对路径、querystring
  let AK = '<管理后台AccessKey>'; //用户的AK(AccessKey)
  let SK = '<管理后台SecretKey>'; //用户的SK(SecretKey)
  let ccApiAuthV1 = 'cc-api-auth-v1' // Authorization 前缀(bce-auth-v1/cc-api-auth-v1 具体看文档)

  const signingKey = crypto

  // 发送 Axios 请求

  axios
