nginx配置文件
server {
listen 80;
...................
# 这个是定义读取你的文件的目录的url开头
location /files {
internal;
alias /home/lvtao.net/upload;
}
....................
}
写个简单的演示
| 代码如下 | 复制代码 |
|
//down.php?filename=lvtao.jpg // 获取文件名 $filename = $_GET["filename"]; header ( "Content-type: application/octet-stream" ); $ua = $_SERVER ["HTTP_USER_AGENT"]; if (preg_match ( "/MSIE/", $ua )) { $encoded_filename = rawurlencode ( $filename ); header ( 'Content-Disposition: attachment; filename="' . $encoded_filename . '"' ); } else if (preg_match ( "/Firefox/", $ua )) { header ( "Content-Disposition: attachment; filename*="utf8''" . $filename . '"' ); } else { header ( 'Content-Disposition: attachment; filename="' . $filename . '"' ); } // "files"是和nginx配置文件的 files要一致 header("X-Accel-Redirect: /files/" . $filename); |
