php header跳转ie问题
电影站提供电影bt下载,由于使用宝丽通播放器,上传电影的时候会同时上传一个电影的hash文件。利用这个hash文件,第一次请求时动态的生成对应的bt种子保存(指定路径)并提供下载。当用户点击下载bt种子的时候,首先到对应的目录下检测对应的bt种子文件是否存在,如果存在,则直接提供下载,否则先生成,再下载。
Bt种子的下载直接在文件中使用header跳转的方式。php文件本身是gbk编码。
后来发现,在chrome和firefox和ie6中都能正常工作,但是到了ie8中会出现找打不文件的情况。这让我很郁闷,ie6都能行,结果ie8还有问题。
[php]
//指向torrent文件,提供下载
//$torrent_file_url = "torrent/tyvod1/科幻片/雷神托尔.torrent"
$redirect_url = "http://vod.cqjtu.edu.cn/".$torrent_file_url;
Header("HTTP/1.1 303 See Other");
Header("Location: ".$redirect_url);
exit ();
经过对比测试,发现如果路径中有中文,ie8就没法下载。php文件本身是GBK编码,于是我们在跳转之前,先将gbk编码的字符串转换为utf8编码。
[php]
//指向torrent文件,提供下载
//$torrent_file_url = "torrent/tyvod1/科幻片/雷神托尔.torrent"
$redirect_url = "http://vod.cqjtu.edu.cn/".$torrent_file_url;
Header("HTTP/1.1 303 See Other");
Header("Location: ".iconv("gbk","utf-8",$redirect_url));
exit ();
这下,在chrome和firefox以及ie8和ie9中都没问题了,但是在ie6中又不能下载了。中文乱码。查资料之后说是因为ie6对UTF-8的支持不够完善。尼玛ie还真难伺候,无论是GBK编码还是UTF-8编码,chrome和firefox都能正确解析,ie自家兄弟居然出这样的问题。
没找到好的办法,只得专门为ie6做一下…

$redirect_url = "http://vod.cqjtu.edu.cn/".$torrent_file_url;
Header("HTTP/1.1 303 See Other");
if(strpos($_SERVER['HTTP_USER_AGENT'],'MSIE 6.0')===false){//非ie6
Header("Location: ".iconv("gbk","utf-8",$redirect_url));
}else{//ie6
Header("Location: ".$redirect_url);
}
exit ();

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,
