The ngx_http_sub_module module is a filter that modifies a response by replacing one specified string by another.
就是把网页中的字符串进行替换 比如t替换成T
Example Configuration
configurationDirectives
Syntax:sub_filter string replacement;
Default:—
Context:http, server, location
string 为所需要替换的字符串,replacement为要替换成的字符,注意使用单引号
Syntax:sub_filter_last_modified on | off;
Default:sub_filter_last_modified off;
Context:http, server, location
就是用于设置网页内替换后是否修改 可在nginx.conf的 http, server, location三个位置配置使 用,默认值是off
Syntax:sub_filter_once on | off;
Default: sub_filter_once on;
Context:http, server, location
控制匹配个数,如果是on 则只匹配第一个,如果off则全部匹配
Syntax:sub_filter_types mime-type ...;
