HTTPS GET URL with URL Encoded Query Params

See more HTTP Examples

Creates a URL with URL encoded query params, and sends an HTTPS GET to the URL. VB.NET

Dim success As Boolean = False

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

' Create a URL with URL-encoded query params.
Dim sbUrl As New Chilkat.StringBuilder
sbUrl.Append("https://www.example.com/something?")

' If we know a query param value does not have any special chars requiring URL encoding,
' just add it.  In this case, there is no need to URL encode "123" because "123" url encoded is still just "123".
sbUrl.Append("abc=123&xyz=")

Dim sbValue As New Chilkat.StringBuilder
sbValue.Append("this is a test")

sbUrl.Append("msg=")
sbUrl.Append(sbValue.GetEncoded("url","utf-8"))

' sbUrl contains:  https://www.example.com/something?abc=123&xyz=msg=this%20is%20a%20test
Debug.WriteLine(sbUrl.GetAsString())

' Send the GET request and get the response body, which is assumed to be text of some sort (HTML, XML, JSON, etc.)
' (Chilkat automatically decompresses gzipped responses)
Dim http As New Chilkat.Http
Dim responseBody As String = http.QuickGetStr(sbUrl.GetAsString())
If (http.LastMethodSuccess = False) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("Response Body:")
Debug.WriteLine(responseBody)
