HTTP Methods - GET and DELETE

Demonstrate a method for sending HTTP requests that don't have a request body, such as for GET or DELETE requests. Visual Basic 6.0

Dim success As Long
success = 0

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

Dim http As New ChilkatHttp

' Specifiy a session log file so we can see the exact request/response
http.SessionLogFilename = "c:/aaworkarea/sessionLog.txt"

' Perhaps add a custom header or two..
http.SetRequestHeader "x-exz-date","20201012T235046Z"
http.SetRequestHeader "x-exz-id","1234"

' Send a GET request to https://www.example.com/someting?param1=123&param2=abc
Dim url As String
url = "https://www.example.com/someting?param1=123&param2=abc"
Dim resp As New ChilkatHttpResponse
success = http.HttpNoBody("GET",url,resp)
If (success = 0) Then
    Debug.Print http.LastErrorText
    Exit Sub
End If

' The GET request that is sent looks like this.
' The Accept and Accept-Encoding headers are automatically added by default.

' 	GET /someting?param1=123&param2=abc HTTP/1.1
' 	Host: www.example.com
' 	Accept: */*
' 	Accept-Encoding: gzip
' 	x-exz-date: 20201012T235046Z
' 	x-exz-id: 1234

' Get the response status
Dim statusCode As Long
statusCode = resp.StatusCode
Debug.Print "Response status: " & statusCode

' Get the response body
Debug.Print resp.BodyStr

' -------------------------------------------------------------
' Let's say we want to send a DELETE request, and we only want to accept an application/json response,
' and we don't want gzipped responses...

' First remove the previously specified custom headers.
http.ClearHeaders 

' Indicate we only accept application/json non-gzipped responses.
http.Accept = "application/json"
http.AllowGzip = 0

' Send a DELETE request to https://www.example.com/deleteSomething
url = "https://www.example.com/deleteSomething"
success = http.HttpNoBody("DELETE",url,resp)
If (success = 0) Then
    Debug.Print http.LastErrorText
    Exit Sub
End If

' The DELETE request that is sent looks like this.
' The empty Accept-Encoding header value means we only want non-compressed responses.

' 	DELETE /deleteSomething HTTP/1.1
' 	Host: www.example.com
' 	Accept: application/json
' 	Accept-Encoding: 

' Get the response status
statusCode = resp.StatusCode
Debug.Print "Response status: " & statusCode

' Get the response body
Debug.Print resp.BodyStr
