Demonstrates how to send a JSON POST using the application/json content-type. Visual Basic 6.0

Dim success As Long
success = 0

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

Dim req As New ChilkatHttpRequest
Dim http As New ChilkatHttp

' If any custom headers need to be included with the POST, add them
' by calling SetRequestHeader

' Note: An application should never explicitly set the Content-Length header.
' The Content-Length is automatically computed and added by Chilkat.

' Here are some examples of custom headers.  

' Perhaps your particular app needs some sort of custom-computed Authorization header...
http.SetRequestHeader "Authorization","my-custom-computed-auth-value"

' Another custom header for some hypothetical app:
http.SetRequestHeader "X-Pass-Timestamp","my-custom-computed-timestamp-value"

' The following "Accept" header may be set, but it really isn't necessary:
http.SetRequestHeader "Accept","application/json"

Dim jsonText As String
jsonText = "{ some JSON text ... }"

' To use SSL/TLS, simply use "https://" in the URL.

Dim resp As New ChilkatHttpResponse
success = http.HttpStr("POST","http://www.someserver.com/someJsonEndpoint",jsonText,"utf-8","application/json",resp)
If (success = 0) Then
    Debug.Print http.LastErrorText
    Exit Sub
End If

' Display the JSON response.
Debug.Print resp.BodyStr
