Question

我正在尝试使用安全websocket（wss）将数据发送到云。云接口仅允许安全的websocket（不允许使用HTTP，非安全的websocket等）

我尝试了最新的master，dev build from nodemcu-build.com，但是SSL失败了。甚至HTTP也无法正常工作。所以我尝试了“1.5.4.1-final”版本。在这里，我验证了SSL适用于HTTPS：

conn=net.createConnection(net.TCP, 1)
> conn:on("receive", function(sck, c) print(c) end )
> conn:on("connection", function(conn)
print("connected")
conn:send("HEAD / HTTP/1.1\r\n"..
"Host: google.com\r\n"..
"Accept: */*\r\n"..
>> "User-Agent: Mozilla/4.0 (compatible; esp8266 Lua;)"..
"\r\n\r\n")
end )
> conn:on("disconnection", function(conn)  print("disconnected") end )
> conn:connect(443,"google.com")
> connected
HTTP/1.1 302 Found

但是当我尝试非安全的websocket和安全的websocket时，只有非安全的websocket才能工作。这是成功的非安全连接的日志：

ws = websocket.createClient()
> ws:on("connection", function()
print('connection opened', status)
end)
> ws:on("receive", function(_, msg, opcode)
print('got message:', msg, opcode) -- opcode is 1 for text message, 2 for binary
end)
> ws:on("close", function(_, status)
print('connection closed', status)
ws = nil -- required to lua gc the websocket client
end)
> ws:connect('ws://echo.websocket.org/')
> connection opened nil

这是因为安全连接失败：

> ws = websocket.createClient()
> ws:on("connection", function()
>> print('connection opened', status)
end)
> ws:on("receive", function(_, msg, opcode)
print('got message:', msg, opcode) -- opcode is 1 for text message, 2 for binary
end)
> ws:on("close", function(_, status)
>> print('connection closed', status)
ws = nil -- required to lua gc the websocket client
end)
> ws:connect('wss://echo.websocket.org/')
> connection closed -128

nodemcu中是否不支持安全websocket？如果没有，我如何获得安全的websocket工作？与非安全相比，安全websocket是否需要额外的代码？

安全websocket（wss）无法在nodemcu中工作
