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。

. w# u) a# o4 d/ c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：
$ ~; |  A7 f9 x

subs_filter_types
! A4 k2 q1 J, ]% D- k syntax: *subs_filter_types mime-type [mime-types] *
4 C$ }  P5 E; }
default: *subs_filter_types text/html*

context: *http, server, location*

  y: W' s6 I- ^6 y4 w7 A+ H4 v*subs_filter_types* is used to specify which content types should be
7 |, r& G5 k7 `" T+ a! _& M; T, q* T checked for *subs_filter*. The default is only *text/html*.

1 u& J4 n/ }6 |8 g1 hThis module just works with plain text. If the response is compressed,
it can’t uncompress the response and will ignore this response. This
+ H5 x, m* F5 N: r  y# m% M module can be compatible with gzip filter module. But it will not work
with proxy compressed response. You can disable the compressed response
like this:

好吧，原来是没指定替换类型，默认只替换html

. l: H* @7 V8 p, x0 A. Y3 ~# n. _7 K在nginx站点配置中加入下面代码：
5 [2 Q* d/ r  M9 R0 Z; t
subs_filter_types text/css text/xml application/xhtml+xml application/xml;

; R# P' N; w  e) z 重启nginx就解决了
