宁波方正建设监理网站怎样推广公司的网站

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)
