What do src=

Nginx中，set $para $1，$1表示路径中正则表达式匹配的第一个参数。

（推荐学习：nginx教程）

以下是一个示例，用以实验$1,$2。如：

location ~/abc/(.*)/(.*) {
 
    set $para1 $1
 
    set $para2 $2
 
    content_by_lua_block {
 
    ngx.say(ngx.var.para1)
 
    ngx.say(ngx.var.para2)
 
    }
 
}

此时，若访问路径为localhost:8080/abc/qwe/asd时，则浏览器会输出。

qwe

asd
