百度智能云 API鉴权总结

最近在研究百度云的一些服务，处理api接口鉴权时花了不少时间，总结一下，方便大家对接：

Signer.php：签名工具类，鉴权签名的核心方法都在这里
Utils.php：封装的工具类，鉴权，返回json数据等都在这里
Account.php：示例Controller，请求百度云接口

签名工具类
封装的工具类，集成了常用的方法
业务层controller：百度api在请求接口的同时做权限校验

使用的tp5框架，代码仅供参考，思路可以供大家借鉴，如有不当之处，欢迎指正

namespace app\index\controller;require 'Utils.php';class Account
{/*** 获得账号信息*/public function info(){$uri = "v1/feed/cloud/AccountFeedService/getAccountFeed";$auth = \Utils::gen_auth($uri);$url = BASE_URL . $uri;$body = ['accountFeedFields' => ['userId','balance','budget','balancePackage','userStat','uaStatus','validFlows',],];//返回数据集成在Utils中\Utils::curl_post($url, $body, $auth);}
