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。

( P  a) C: [% D; E+ h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：

# V) o& g( T' [( r( K

subs_filter_types
2 Y/ i" E2 s# t* D8 g syntax: *subs_filter_types mime-type [mime-types] *

default: *subs_filter_types text/html*

/ _, z9 l* o- [7 ]3 N9 fcontext: *http, server, location*

*subs_filter_types* is used to specify which content types should be
* Y  a. e0 J! X. W" s& k: s. ^3 S checked for *subs_filter*. The default is only *text/html*.

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

好吧，原来是没指定替换类型，默认只替换html

- K0 P% c3 }6 G8 T' U在nginx站点配置中加入下面代码：
