Migrating from BareboneThunks to cTlsSocket #3

This will be more generic than the other questions, I apologize if I went too blurred here like if it was me from like 2022.

How do we implement chunked transfer in sync data receiving?

Private Sub FetchChannelMessages(ByVal sChannelId As String, Optional ByVal lLimit As Long = 10)

    Dim tlsSocket As New cTlsSocket
    Dim sPayload As String
    Dim sRequest As String
    Dim sResponse As String
    
    
    ' Create the API request path
    Dim sPath As String
    sPath = "api/v10/channels/" & sChannelId & "/messages?limit=" & lLimit
    
    sRequest = "GET /" & sPath & " HTTP/1.1" & vbCrLf & _
              "Host: " & m_sBaseUrl & vbCrLf & _
              "Authorization: " & m_sToken & vbCrLf & _
              "Connection: close" & vbCrLf & vbCrLf
    
    ' Configure and connect socket
    ' Allow TLS 1.2 or 1.3
    tlsSocket.SyncConnect "discord.com", 443, , , ucsTlsSupportAll Or ucsTlsIgnoreServerCertificateErrors
    
    ' Send request
    tlsSocket.SyncSendText sRequest
    
    ' Receive response (blocking)
    sResponse = tlsSocket.SyncReceiveText
    
Open App.Path + "\fcm.txt" For Output As #1
'ParseHttpResponse(sResponse, False)
Print #1, sResponse
Close #1
    ' Clean up
    tlsSocket.Close_
    Set tlsSocket = Nothing

End Sub

Unlike the other functions, this is supposed to receive a quite long data.

It got trimmed in 6821 characters, It's quite a weird number but HTTP headers likely don't count in the chunked transfers.
I'm pretty sure the server uses chunked transfering.

Try NeedLen parameter on SyncReceiveXxx methods if know beforehand the size of the remaining chunk.

I will check the unofficial user docs. I doubt they documented such a thing as these docs are often designed for HTTP libraries rather than TCP libraries.

[gaouservbf]

Nope, its dynamic.

It might be dynamic but you have to be able to calculate it from the initially received part (header). For instance in http protocol there is Content-Size header which can be used to fetch remaining chunk of the actual body.

Ah wait.. Yeah. Thanks for reminding me of it, I will do a return once I try it.

Worked. Thanks for your support!
