Question

thinkphp 使用http扩展类 下载png等图片格式文件正常，但是下载doc，zip等文件时没有后缀

上传正常，下载png也是正常，就是doc，zip这类的文件下载下来，没有后缀打不开。怎么个情况呢？

Answer 1

header 制定的下载类型不对，
$extension=pathinfo($file, PATHINFO_EXTENSION);
switch ($extension){
case "jpg":
case "jpeg": $ctype="image/jpeg"; break;
case "pdf": $ctype="application/pdf"; break;
case "gif": $ctype="image/gif"; break;
case "png": $ctype="image/png"; break;
case "doc": $ctype="application/msword"; break;
case "zip": $ctype="application/zip";break;
case "rar": $ctype="application/rar"; break;
case "mp3": $ctype="audio/mpeg3"; break;
case "avi": $ctype="video/avi"; break;
case "doc": $ctype="application/msword";break;
case "xls": $ctype="application/vnd.ms-excel"; break;
case "wav": $ctype="audio/wav"; break;
case "htm": $ctype="text/html"; break;
case "txt": $ctype="text/plain"; break;
case "flv": $ctype="flv-application/octet-stream"; break;
case "mp4": $ctype="video/mp4"; break;
default: $ctype="application/force-download"; //$ctype="application/octet-stream";
}
header("Content-type: ". $ctype);

下载这里文件如果没问题，加个后缀就能打开的话，那就是你文件名设置的有问题，只要获取上传的文件名加在后面就行了
