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。
. d: H0 y6 F* j, P* u* d; l3 x+ J
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：
* o% E$ y, X' k7 I9 R+ i5 w  h! V5 J

subs_filter_types
syntax: *subs_filter_types mime-type [mime-types] *
0 g3 @" ~3 }, \3 s, j
; ^% m% U+ x3 o% s* ]0 \7 l7 P9 O2 Wdefault: *subs_filter_types text/html*
& b% @& j* D' w' K
- Y: @( H3 J4 p8 D- g- q" L+ scontext: *http, server, location*

7 Y6 b: l( z& D( T" Q*subs_filter_types* is used to specify which content types should be
2 K3 d- T' G1 v+ p7 G checked for *subs_filter*. The default is only *text/html*.

This module just works with plain text. If the response is compressed,
/ K8 v5 M1 b5 ?' T it can’t uncompress the response and will ignore this response. This
module can be compatible with gzip filter module. But it will not work

like this:
( B+ f0 W; O& Z9 t/ w0 g
' I$ X) F' H$ b8 V- F0 X% Qproxy_set_header Accept-Encoding “”;

" }8 l8 b4 `6 J9 |' u
3 l. t) k( A& G2 v: h) s, T4 d- a好吧，原来是没指定替换类型，默认只替换html
3 i6 I; g* [. e+ a
在nginx站点配置中加入下面代码：
7 Q; _* S2 e. g; ?1 i. z5 \7 W' x
subs_filter_types text/css text/xml application/xhtml+xml application/xml;
  V- D4 I5 {3 p
重启nginx就解决了
