tolua 调用unitywebrequest 无反应

[azmja]

tolua 调用unitywebrequest 无反应，tolua中调用CS.UnityEngine.Networking.UnityWebRequest.Get(url) 时候 CS.UnityEngine.Networking 无法被识别，我尝试将CS.UnityEngine.Networking _GT(typeof(UnityWebRequest))引入，是可以使用unitywebrequest的 但是却无法收到request.downloadHandler.text的消息，下面是我的代码 ，很困扰
local co = coroutine.create(function()
request = UnityEngine.Networking.UnityWebRequest.Get(Localurl);

 logGreen("----开启协程 开启coroutine")
yield_return(request:SendWebRequest())
logGreen("----111111111111111111111")
if (request.isHttpError or request.isNetworkError) then
logGreen(request.error)
else
logGreen(request.downloadHandler.text)
end

end)
