关键配置《nginx + lua 字符串过滤实现blogger站点的反向代理》

 具体的编译和配置过程略过，仅贴出nginx关键配置部分如下：

server {

        listen       80;

        server_name  blog.youhost.com;

 

        location / {
#lua字符替换 部分

body_filter_by_lua

'

    local origstr= ngx.arg[1]

    origstr=string.gsub(origstr,"www.blogger.com","blog.youhost.com/blg")

    origstr=string.gsub(origstr,"www.Blogger.com","blog.youhost.com/blg")

    origstr=string.gsub(origstr,"us.zyh.me","blog.youhost.com")

    origstr=string.gsub(origstr,"img1.blogblog.com","blog.youhost.com/img1")

    origstr=string.gsub(origstr,"img2.blogblog.com","blog.youhost.com/img2")

    origstr=string.gsub(origstr,"img3.blogblog.com","blog.youhost.com/img3")

    origstr=string.gsub(origstr,"www.blogblog.com","blog.youhost.com/bbwww")

 

    ngx.arg[1]=origstr
