By "arbitrary" I mean that here you can set the request method, add headers, and set the body. WinINet itself will also add some headers to the request, I suppose.
Here's the code:
Code: Select all
#undef data
#include once "windows.bi"
#include once "win\wininet.bi"
Type http_response
Declare Function toString() As String
As Integer status
As String headers, body
End Type
Type http_request
Declare Constructor( _
host As String, _
url As String = "", _
method As String = "", _
headers As String = "", _
body As String = "" _
)
Declare Function send() As http_response
As String host
As String url, method
As String headers, body
End Type
Constructor http_request( _
host As String, _
url As String = "", _
method As String = "", _
headers As String = "", _
body As String = "" _
)
With this
.host = host
.url = url
.method = method
.headers = headers
.body = body
End With
End Constructor
