加签名验证就行。提供密钥进行MD5。
首先，安全起见，最好使用HTTPS通信，以防止中间人截获。
其次，在HTTPS的前提下，对于API访问权限控制可以在，请求头里面添加一个字段传输Token（或者直接放在URL里面也行），该Token由服务器分配，服务器通过Token对用户权限进行权限控制。
Token不合法，就不返回数据即可。
如果你的合法是未授权调用 那直接用类似appkey就可以了
如果非法使用别人的授权 只能绑定ip域名 没看各种app的key都被别人拿来用了么 比如weico的
用公钥,MD5出来的加密串，再自己手动添加若干个字符串进去，看你怎么破？根本不算MD5，这个加密串，你一份，调用者一份，每次请求API的时候，构造方法里面先去验证这个token是否正确，如果不正确，说明别人在试探你的API，你直接发送404，告诉他找不到，故意去误导他，再来狠点，每个月去更换一次token，看你如何破？

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
