Question

我将简要说明我的问题，我需要修剪前14个字符（0-9和-），下载文件时，它仅与标题Content-Disposition有关，如何达到这样的目标？

我希望文件看起来像这样：

1235467890123-FileName.txt

为此

FileName.txt

配置文件：

upstream oxide_io {
    ip_hash;

    server 127.0.0.1:xxx;
    server 127.0.0.1:xxx;
    server 127.0.0.1:xxx;
}

server {
    listen 443      ssl http2;
    listen [::]:443 ssl http2;

    server_name oxidepolska.pl;
    error_log /var/log/nginx/forum-error.log error;

    ssl ***

    proxy_hide_header X-Powered-By;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;

    proxy_set_header Host $http_host;
    proxy_set_header X-NginX-Proxy true;
    proxy_redirect off;

    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";

    gzip ***

    location @oxide {
        proxy_pass http://oxide_io;
    }

    location ~ ^/assets/(.*) {
        root /var/www/forum/;
        try_files /build/public/$1 /public/$1 @oxide;
    }

    location /plugins/ {
        root /var/www/forum/build/public/;
        try_files $uri @oxide;
    }

    location ~ ^/public/uploads/files/(.*)$ {
        root /var/www/forum/public/uploads/files/;
        add_header Content-Disposition 'inline; filename="$1"';
    }

    location / {
       proxy_pass http://oxide_io;
    }

    error_page 502 503 /503.html;

    location = /503.html {
    root /var/www/forum/public/;
    }
}

server {
    if ($host = oxidepolska.pl) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    listen 80;
    listen [::]:80;

    server_name oxidepolska.pl;
}

Answer 1

免责声明：：此答案是关于修改现有的Content-Disposition标头，这不是OP所要求的。

map $upstream_http_content_disposition $content_disposition {
    default $upstream_http_content_disposition;
    '~^(.*filename="?)[-\d]{14}(.+?)("?$)' $1$2$3;
}

server {

    ...

    location @oxide {
        proxy_pass http://oxide_io;
        proxy_hide_header Content-Disposition;
        add_header Content-Disposition $content_disposition;
    }

    ...

    location / {
        proxy_pass http://oxide_io;
        proxy_hide_header Content-Disposition;
        add_header Content-Disposition $content_disposition;
    }

    ...

}

（假设前14个字符只能是0-9和'-'）

Answer 2

据我最终了解，您正在尝试摆脱添加到某个论坛上载文件中的时间戳前缀吗？这是另一个配置，手动添加Content-Disposition标头：

map $uri $content_disposition {
    '~/\d{13}-([^/]+)$' 'attachment; filename="$1"';
}

server {

    ...

    location <uploaded_files_location> {
        add_header Content-Disposition $content_disposition;
    }

    ...

}

当请求的文件与模式\ d {13}-不匹配时（文件名其余部分前有13位数字和“-”符号），$ content_disposition变量评估为空字符串，因此不添加Content-Disposition头回应。
