Nginx 中 proxy_pass uri 中的主机名的正则表达式

我想做类似的事情：

server_name   ~^(www\.)?(?<subdomain>[^.]+).example.org$;

location / {
    proxy_pass      "http://example.org:8080/$subdomain";
}

答案1

未经测试，但可以尝试一下：

server_name   ~^(www\.)?[^.]+.example.org$;

if ($host ~* ^(www\.)?([^.]+).example.org$) {
    set $subdomain $2;
}

location / {
    proxy_pass http://example.org:8080/$subdomain;
}

答案2

已测试并正常运行：

server_name "~(.*).dummy.local";

location / {
    echo $1;
}

请求的时候foo.dummy.local会显示foo。

curl -vvv foo.dummy.local
* Rebuilt URL to: foo.dummy.local/
*   Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to foo.dummy.local (127.0.0.1) port 80 (#0)
