php下载文件不显示进度条
我有一个程序 要求把下载的文件夹重命名于是在网上找了段代码 如下:
header("Content-type:application/octet-stream");
header("Accept-Ranges:bytes");
header("Content-Type:application/force-download");
header("Content-Disposition:inline;filename=".$filename);
header("Accept-Length:".filesize($File));
@readfile($File);//读取文件到输出缓存
可是下载文件时只显示打开文件多少多少。。。 不显示下载进度啊
回复讨论(解决方案)
你说的下载进度是啥地方的下载进度?
就是下载文件时ie弹出的那个下载对话框啊 没有进度条 显示打开多少多少K 一会直接就下载完了
可能是浏览器的原因吧,你换火狐浏览器试试!
换个浏览器试试,用火狐呢
怎么没人啊
没用的。
浏览器无法获得文件的大小,就无法计算比例、生成进度条。

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,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
