nginx+lua 设置跨域

nginx 配置：

header_filter_by_lua_file cros.lua;
access_by_lua '
if ngx.var.request_method == "OPTIONS" then
return 203
end
';

cros.lua:

if string.find(ngx.var.http_origin,":8008") then          //判断request的origin
ngx.header["Access-Control-Allow-Credentials"] = "true"
ngx.header["Access-Control-Allow-Origin"] = ngx.var.http_origin
ngx.header["Access-Control-Allow-Headers"] = "x-requested-with,content-type"
if ngx.var.request_method == "OPTIONS" then                                        ngx.header["Access-Control-Max-Age"] = "86400"
ngx.header["Access-Control-Allow-Methods"] = "GET, POST, OPTIONS, DELETE"
ngx.header["Content-Length"] = "0"
ngx.header["Content-Type"] = "text/plain, charset=utf-8"
end 
 end
