HTTP字符串替换( http_sub_module )

配置语法

| http_sub_module | 字符串替换 | | 替换一次 | | :--- | :--- | :--- | :--- | :--- | | 语法 | sub_filter string replacement | sub_filter_last_modified on | of | sub_filter_once on | off | | 默认 | --- | sub_filter_last_modified off | sub_filter_once on | | 作用域 | http,server,location | http,server,location | http,server,location |

例子:

    location / {
        root   /www/nginx/code; 
        # 将字符串 king 替换为 kingofzihua
        sub_filter 'king' 'kingofzihua';
        #全局替换,默认只会替换一次
        sub_filter_once off; 
    }

    # 注意,只能替换html文件,txt 文件不可以! 而且只替换一次,如果要是全局替换的话要用sub_filter_once
