将字符串从VB6 Winsock发送到WebSocket
我正在制作一个连接到WebSocket的VB6应用程序,握手和保留数据部分按我的需要工作,目前我在通过Winsock将字符串发送回WebSocket时遇到了困难 我指的是这篇博客文章,是关于websocket握手之类的 我试过这样做将字符串从VB6 Winsock发送到WebSocket,websocket,vb6,winsock,Websocket,Vb6,Winsock,我正在制作一个连接到WebSocket的VB6应用程序,握手和保留数据部分按我的需要工作,目前我在通过Winsock将字符串发送回WebSocket时遇到了困难 我指的是这篇博客文章,是关于websocket握手之类的 我试过这样做 Private Declare Sub CopyMemory _ Lib "kernel32" _ Alias "RtlMoveMemory" (Destination As Any, _

Private Sub Form_Load()
Winsock1.LocalPort = 6701
Winsock1.Listen
End Sub
Private Sub cmdCommand1_Click()
Dim str As String
Dim BT() As Byte
str = StrConv(tbMsg.Text, vbUnicode)
If WinSock1.State = sckConnected Then
ReDim BT(Len(str) - 1)
CopyMemory BT(0), str, Len(str)
WinSock1.SendData StrConv(BT, vbUnicode)
End If
End Sub
从这个方法来看,我在浏览器中遇到了一个错误,比如
到“ws://127.0.0.1:6701/”的WebSocket连接失败:服务器不能屏蔽它发送给客户端的任何帧
我也试过
WinSock1.SendData StrToByte(tbMsg.Text, vbUnicode)
Public Function StrToByte(strInput As String) As Byte()
Dim lPntr As Long
Dim bTmp() As Byte
Dim bArray() As Byte
If Len(strInput) = 0 Then Exit Function
ReDim bTmp(LenB(strInput) - 1) 'Memory length
ReDim bArray(Len(strInput) - 1) 'String length
CopyMemory bTmp(0), ByVal StrPtr(strInput), LenB(strInput)
For lPntr = 0 To UBound(bArray)
If bTmp(lPntr * 2 + 1) > 0 Then
bArray(lPntr) = Asc(Mid$(strInput, lPntr + 1, 1))
Else
bArray(lPntr) = bTmp(lPntr * 2)
End If
Next lPntr
StrToByte = bArray
End Function
Private Sub cmdCommand1_Click()
Dim abData() As Byte
Dim i As Long
Str = tbMsg.Text
' Convert string to bytes
abData = StrConv(Str, vbFromUnicode)
For i = 0 To UBound(abData)
Debug.Print Hex(abData(i)); "='" & Chr(abData(i)) & "'"
Next
If VoicePrintSocket.State = 7 Then VoicePrintSocket.SendData abData
End Sub
从这个方法中,我得到一个类似浏览器的错误
到“ws://127.0.0.1:6701/”的WebSocket连接失败:一个或多个保留位打开:reserved1=1、reserved2=0、reserved3=1
我也试过
