hi 春哥,
我在做限速的时候， 使用了limit_rate和limit_rate_after 我发现 对ngx.var.limit_rate赋值是ok的 但是对ngx.var.limit_rate_after赋值报错
请问这个是不可变变量，还是其他？ 谢谢
local suffix = get_resource_suffix(uri)
if suffix == "mp4" then
ngx.var.limit_rate_after = "8m"
elseif suffix == "ts" then
ngx.var.limit_rate_after = "2m"
elseif suffix == "m3u8" then
ngx.var.limit_rate_after = "5m"
end
ngx.var.limit_rate = req_limit_rate
