建立垃圾箱file

当我在添加HTTPS模块之前请求tls请求时，在我添加-1模块并请求tls重新启动NodeMCU之后，它返回了代码HTTPS。

我用来发送请求的代码。

   print(node.heap()) -- 31824
   http.request("https://www.google.com", "HEAD", "", "", 
   function(code, data)
      if (code < 0) then
        print("HTTP request failed")
      else
        print(code, data)
      end
    end)

然后我尝试了net模块。

   print(node.heap()) -- 31824
   srv = tls.createConnection()
   srv:on("receive", function(sck, c) print(c) end)
   srv:on("connection", function(sck, c)
   sck:send("GET / HTTP/1.1\r\nHost: google.com\r\nConnection: keep-alive\r\nAccept: */*\r\n\r\n")
end)
   srv:connect(443,"google.com")

两个代码的重启原因相同。

HTTP client: hostname=google.com
HTTP client: port=443
HTTP client: method=GET
HTTP client: path=/
HTTP client: DNS request
HTTP client: DNS pending
> HTTP client: DNS found google.com 172.217.18.46

在网络模块代码中，重新启动会在调用srv:connect(443,"google.com")并显示另外一行RecvHold, By pespconn,find conn_msg fail

时发生

Answer 1

假设错误的日期是因为您最近执行了某项操作，因此建议您将时间设置为最近的时间。如果您的时间变化太大，则您的操作系统将无法正常运行。如果NTP拒绝您的连接，请手动设置时间。如何设置RTC rtctime module，但还要查看sntp模块或其他相关模块。

Answer 2

我通过使用具有相同模块和相同配置的 Docker 构建相同的SDK Firmware 2.2.1来解决此问题，无法控制案例和生产线以在 Cloud Build < / strong>版本，因此无法知道 Cloud Build 中到底出了什么问题。
