我通过 nginx 的 $upstream_http_content_type 判断类型是否是图片，代码如下：

add_header X-Content-Type $upstream_http_content_type;

if ($upstream_http_content_type ~* ^image/(jpg|jpeg|pjpeg|png|x-png|gif|bmp|x-icon|webp|svg\+xml)) {
    return 301;
}

可结果是 X-Content-Type 倒是有了，却没有 301 跳转？

理论上应该酱紫啊：

呃，我是想判断所有类型是图片的请求都单独处理。。。

完整代码：

location ~ /url {
if ($request_uri ~ /(http|https|ftp)://([^/]+)/(.+)) {
set $proxyurl $1://$2/$3;
set $proxyhost $2;
set $proxyref $1://$2;
}

proxy_pass $proxyurl;
proxy_pass_header Server;
proxy_redirect off;
proxy_set_header Accept-Encoding "";
proxy_set_header Host $proxyhost;
proxy_set_header Referer $proxyref;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_hide_header Content-Type;

add_header X-Content-Type $upstream_http_content_type;

if ($upstream_http_content_type ~* ^image/(jpg|jpeg|pjpeg|png|x-png|gif|bmp|x-icon|webp|svg\+xml)) {
# 如果类型是图片，就？
}

error_page 301 302 400 403 404 500 502 503 504 = @check_header;
}

location @check_header {
rewrite ^ /ErrorPages/404.html;
}

少写了个，下面是修复的：

location ~ /url {

set $proxyurl "http://www.xxx.com";
set $proxyhost "www.xxx.com";
set $proxyref "http://www.xxx.com";

if ($request_uri ~ /(http|https|ftp)://([^/]+)/(.+)) {
set $proxyurl $1://$2/$3;
set $proxyhost $2;
set $proxyref $1://$2;
}

proxy_pass $proxyurl;
proxy_pass_header Server;
proxy_redirect off;
proxy_set_header Accept-Encoding "";
proxy_set_header Host $proxyhost;
proxy_set_header Referer $proxyref;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_hide_header Content-Type;

add_header X-Content-Type $upstream_http_content_type;

if ($upstream_http_content_type ~* ^image/(jpg|jpeg|pjpeg|png|x-png|gif|bmp|x-icon|webp|svg\+xml)) {
# 如果类型是图片，就？
}

error_page 301 302 400 403 404 500 502 503 504 = @check_header;
}

location @check_header {
rewrite ^ /ErrorPages/404.html;
}
