解决nginx反代Discuz论坛登录跳回源站的问题

大叔

反代了一个论坛，输入账号密码登录后，会跳转回原来的站。用了subs_filter也一样。

一直在苦恼这个问题，经某人点拨，Discuz跳转的文件是xml后缀的（详情哪个文件我也不知道….）

打开ngx_http_substitutions_filter_module的github看到：
( Q( j& b) c% j) p$ m

subs_filter_types
syntax: *subs_filter_types mime-type [mime-types] *

*subs_filter_types* is used to specify which content types should be
checked for *subs_filter*. The default is only *text/html*.

This module just works with plain text. If the response is compressed,

module can be compatible with gzip filter module. But it will not work

like this:

好吧，原来是没指定替换类型，默认只替换html

在nginx站点配置中加入下面代码：

- O4 P& h: K/ j3 E4 \' w2 v subs_filter_types text/css text/xml application/xhtml+xml application/xml;

重启nginx就解决了
