Question:

ChilkatHttp: ssl handshake failure

Dec 31 '16 at 05:47

Hi,

Before updating a legacy app I am trying ChilkatHttp with different scénarios

I am unable to properly request the url https://requestb.in/zjdmfzzj

this url should return "ok" (tested with the browser, postman and the old component)

Bellow is the code used and the result of the execution.

Am I doing something wrong ?

The code:

Private Sub test1()
    Dim http As New ChilkatHttp

    Dim success As Long

    '  Any string unlocks the component for the 1st 30-days.
    success = http.UnlockComponent("Chilkat_HTTP_licence")
    If (success <> 1) Then
        Debug.Print http.LastErrorText
        Exit Sub
    End If

    '  Send the HTTP GET and return the content in a string.
    Dim html As String
    html = http.QuickGetStr("https://requestb.in/zjdmfzzj")

    Debug.Print "html: " & html
    Debug.Print vbCrLf & "--------" & vbCrLf & "LastMethodSuccess: " & http.LastMethodSuccess
    Debug.Print vbCrLf & "--------" & vbCrLf & "LastErrorText: " & http.LastErrorText
End Sub

The result:

html:

--------
LastMethodSuccess: 1
