NodeMCU，Lua http.get（）" Disconnected with error 8" - 什么是错误8？ [英] NodeMCU, Lua http.get() "Disconnected with error 8" - what is error 8?

问题描述

我尝试使用http.get（url，header，function）从Firebase获取数据。

Im trying to use http.get(url, headers, function) to get data from Firebase.

Othersites（也是https网站）工作正常，我得到了我希望回应，但firebase给了我一个错误8.

Othersites (also https sites) work fine and i get the response i expect, but firebase gives me a error 8.

我找不到任何关于此错误的文档（或任何错误） - 有谁知道这意味着什么？

I cant find any documentation of this error (or any errors) - does anyone know what it means?

http.get("https://<my-firebaseID>.com/somefile.json", "", function(code, data)
    if (code < 0) then
      print("HTTP request failed")
    else
      print(code, data)
    end
  end)

推荐答案

我可以提供正确但仍然不满意的答案 - 这是一个已知问题，请参阅 https://github.com/nodemcu/nodemcu-firmware/issues/1707 。如果您构建启用了调试的固件，您可能会看到类似于该问题中报告的消息。

I can provide a correct but still dissatisfactory answer - it's a known issue, see https://github.com/nodemcu/nodemcu-firmware/issues/1707. If you build a firmware with debug enabled you'll likely see messages similar to the one reported in that issue.
