在程序本地运行很正常,上传到服务器后,发现图片没有显示出来,图片链接是绝对路径 var/...,而且当中带有 \ 但是我记得这个路径已经处理成相对路径的
$path = dirname(dirname(dirname(__FILE__))).'\\'; $search = array( $path, '\\'); $replace = array( '', '/'); return str_replace($search,$replace,$this->tempfolder).$this->filename_prefix.$public.'.jpg'; |
可以各位也看出来了,第一行代码的用在LINUX “\\”, 就不行。
解决的办法是 用PHP 预定义常量 DIRECTORY_SEPATRATOR来代替'\','/'这样的路径分隔符,以前觉得既然windows,LINUX 都支持/,那都用成 / 得了,这是没错的。可是从这个例子可以看出,当要对路径字符串进行处理的时候,就比较危险了,所以最好还是用DIRECTORY_SEPATRATOR吧。

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

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,
