more_set_headers 问题求解

stonehuzhan

静态pdf文件，目的是让网页直接提示用户保存

配置如下：

location ~ /sync/dl/[0-9]+/(.+)\.pdf {

more_set_headers "Content-Type:application/octet-stream";

more_set_headers "Content-Disposition: attachment;filename=$1";

more_clear_headers "Location";

alias /opt/track/data/;

}

输出确实 301 并且location 多一个 /

[root@HZ4 ~]# curl -I "http://192.168.0.17/sync/dl/18/4201E7A296C640270C7d57g0.pdf"

HTTP/1.1 301 Moved Permanently

Server: nginx/1.3.10

Date: Mon, 21 Jan 2013 07:39:21 GMT

Content-Type: application/octet-stream;

Content-Length: 185

Location: http://192.168.0.17/sync/dl/18/4201E7A296C640270C7d57g0.pdf/

Connection: keep-alive

Content-Disposition: attachment;filename=4201E7A296C640270C7d57g0.pdf

如果不用正则式匹配，可以网页正常提示用户保存，但是文件名只能写死

location /sync/dl {

more_set_headers "Content-Type:application/octet-stream";

more_set_headers "Content-Disposition: attachment;filename=1.pdf";

alias /opt/track/data/;

}

返回200 但是文件名只能写死

方案1

location /sync/dl {

more_set_headers "Content-Type:application/octet-stream";

more_set_headers ": ";

header_filter_by_lua 'ngx.header["Content-Disposition"] = "attachment;filename=" .. string.match(ngx.var.uri, "^/sync/dl/%d+/(.+)$")';

alias /opt/track/data/;

}

方案2

location /sync/dl {

set $f "";

if ($uri ~ "^/sync/dl/\\d+/(.+)$“) {

set $f $1;

}

more_set_headers "Content-Type:application/octet-stream";

more_set_headers "Content-Disposition: attachment;filename=$f";

alias /opt/track/data/;

}

方案3

使用 map ( http://wiki.nginx.org/HttpMapModule )

类似方案2，只是 set $f 变成 map $f {} ，具体写法请随便研究下。

随便估计，应该 map 的方案性能最好。

thx 已经搞定。

location /sync/dl/ {

alias /opt/track/data/;

more_set_headers "Content-Type:application/octet-stream";

if ($request_filename ~* ^.*/([^/]*?)$) {

set $exits true;

set $msi $1;

}

if ($exits) {

add_header Content-Disposition: "attachment; filename=$msi";

}
