Demonstrates how to calculate the X-Signature header and add to requests sent to api.test.hotelbeds.com. VB.NET

Dim success As Boolean = False

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' This example duplicates the following CURL statement provided in the hotelbeds.com "Getting Started"
' developer documentation:

' #!/bin/bash 
' apiKey="yourApiKey"
' secret="yourSecret"
' curl -i \
'   -X GET \
'   -H 'Accept:application/json' \
'   -H 'Api-key:'$apiKey'' \
'   -H 'X-Signature:'$(echo -n ${apiKey}${secret}$(date +%s)|sha256sum|awk '{ print $1}')'' \
'   https://api.test.hotelbeds.com/hotel-api/1.0/status

' The "date + %s" command emits a UNIX date/time number such as 1605548842
' We need to concatenate the apiKey, secret, and current date/time in UNIX (numeric) time format.
Dim dt As New Chilkat.CkDateTime
dt.SetFromCurrentSystemTime()
' Get the UNIX time string in the GMT timezone.
Dim bLocalTime As Boolean = False
Dim unixTimeStr As String = dt.GetAsUnixTimeStr(bLocalTime)
Debug.WriteLine(unixTimeStr)

' Use your own API key and secret.  (These are not valid values)
Dim apiKey As String = "227b20a2cb705e45f3b0a0944672dc07"
Dim secret As String = "54dc7ba9e2"

Dim sb As New Chilkat.StringBuilder
sb.Append(apiKey)
sb.Append(secret)
sb.Append(unixTimeStr)

Dim crypt As New Chilkat.Crypt2
crypt.HashAlgorithm = "sha256"
crypt.EncodingMode = "hexlower"
Dim signature As String = crypt.HashStringENC(sb.GetAsString())

Debug.WriteLine(signature)

Dim http As New Chilkat.Http

http.SetRequestHeader("Accept","application/json")
http.SetRequestHeader("Api-key",apiKey)
http.SetRequestHeader("X-Signature",signature)

Dim jsonResponse As String = http.QuickGetStr("https://api.test.hotelbeds.com/hotel-api/1.0/status")
Debug.WriteLine(jsonResponse)
