}注意： 使用 nginx 的静态资源目录作为 文件的存放，那么在下载文件时，想要 txt ,html ,pdf 等文件直接被下载而不被浏览器打开时，可在 nginx 的配置文件加入以下配置
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
if ($request_filename ~* ^.*?.(txt|doc|pdf|rar|gz|zip|docx|exe|xlsx|ppt|pptx|jpg|png|html|xml)$){
add_header Content-Disposition attachment;
add_header Content-Type 'APPLICATION/OCTET-STREAM';
}
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}重点是 :
if ($request_filename ~* ^.*?.(txt|doc|pdf|rar|gz|zip|docx|exe|xlsx|ppt|pptx|jpg|png|html|xml)$){
add_header Content-Disposition attachment;
add_header Content-Type 'APPLICATION/OCTET-STREAM';
}
或者也可以这样处理：
if ($args ~* "target=download") {
add_header Content-Disposition 'attachment';
add_header Content-Type 'APPLICATION/OCTET-STREAM';
}
这样的话只要在 get请求加上 target=download 参数就可以下载了。
