PHP解密Unicode及Escape加密字符串
PHP解密Unicode及Escape加密字符串
在json中不支持中文,用它传送中文数据就会出现数据丢失或者乱码,必须在传送前对要发送的字符串进行编码,由于传送过去需要用js进行数据解析,考虑 到js中有unescape函数,故若在php中有个escape函数,对数据进行编码,在客户端用unescape进行 解码,这样就会方便很多。

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,
