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

' Let's say we want to send a GET request to 
' https://example.com/search?query=hello%20world&category=books&sortBy=price&filterBy=inStock

' Notice that the query parameter values must be URL encoded.

' Let's also explain the parts of the above URL:

'     Scheme: https
'         The scheme specifies the protocol used to access the resource. 
'         In this case, it is "https," which indicates that the resource is accessed using the Hypertext Transfer Protocol Secure (HTTPS).
' 
'     Host: example.com
'         The host part of the URL identifies the domain name or IP address of the server hosting the resource. In this case, "example.com" is the host.
' 
'     Path: /search
'         The path is the specific location or resource on the server that the client wants to access. 
'         In this URL, the path is "/search," indicating that the client is requesting the "search" resource on the server.
' 
'     Query Parameters:
'         Query parameters are used to send additional data to the server as key-value pairs. 
'         They are separated from the path by a question mark ? and each parameter is separated by an ampersand &.
' 
'         The above URL has four query parameters:
'             query=hello%20world: The "query" parameter with the value "hello world". The %20 represents the URL-encoded space character in the value.
'             category=books: The "category" parameter with the value "books".
'             sortBy=price: The "sortBy" parameter with the value "price".
'             filterBy=inStock: The "filterBy" parameter with the value "inStock".

set rest = Server.CreateObject("Chilkat.Rest")

' Connect to the REST server.

' The Host part of the URL is passed in the 1st argument.
' The Scheme part of the URL ("https") is indicated by the 2nd and 3rd arguments (port and bTls).
bTls = 1
port = 443
bAutoReconnect = 1
success = rest.Connect("example.com",port,bTls,bAutoReconnect)

' There are 3 ways to send the above GET request.

' 1) Send the request with path and query params pre-built, where the query param values are URL encoded.
responseJson = rest.FullRequestNoBody("GET","/search?query=hello%20world&category=books&sortBy=price&filterBy=inStock")
If (rest.LastMethodSuccess <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( rest.LastErrorText) & "</pre>"
    Response.End
End If

' 2) Pass only the Path part of the URL, and specify the query params separately by calling AddQueryParams beforehand.
'    Again, the query params must be already URL encoded when passed to AddQueryParams
success = rest.ClearAllQueryParams()
success = rest.AddQueryParams("query=hello%20world&category=books&sortBy=price&filterBy=inStock")
responseJson = rest.FullRequestNoBody("GET","/search")
' ...
' ...

' 3) Pass each query parameter separately by calling AddQueryParam.  In this case, the query param value should be passed without URL encoding.
'    (ClearAllQueryParams ensures any params set for previous request are cleared.)
success = rest.ClearAllQueryParams()
success = rest.AddQueryParam("query","hello world")
success = rest.AddQueryParam("category","books")
success = rest.AddQueryParam("sortBy","price")
success = rest.AddQueryParam("filterBy","inStock")
responseJson = rest.FullRequestNoBody("GET","/search")
' ...
