Demonstrates how to generate a QR code using the api.qrserver.com REST API service. AutoIt

Local $bSuccess = False

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

$oHttp = ObjCreate("Chilkat.Http")

; Send the following GET request to get a binary response.
; The body of the binary response contains the image data for the QR code.
; https://api.qrserver.com/v1/create-qr-code/?data=[URL-encoded-text]&size=[pixels]x[pixels]

$oQueryParams = ObjCreate("Chilkat.JsonObject")
$oQueryParams.UpdateString("data","Hello World")
$oQueryParams.UpdateString("size","100x100")

; Get a PNG file..
; Possible formats are:
; png
; gif
; jpeg
; jpg
; svg
; eps
; Case matters.  Use lowercase.
$oQueryParams.UpdateString("format","png")

; Send the GET request to an endpoint.
; Chilkat will add the url-encoded query params passed in the JSON.
$oResp = ObjCreate("Chilkat.HttpResponse")
$bSuccess = $oHttp.HttpParams("GET","https://api.qrserver.com/v1/create-qr-code/",$oQueryParams,$oResp)
If ($bSuccess = False) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

; Did it succeed?
If ($oResp.StatusCode <> 200) Then
    ; The response body, if anything, would not be the image data, but would likely be the error text (or HTML, or whatever...)
    ConsoleWrite($oResp.BodyStr & @CRLF)
    ConsoleWrite("Response status = " & $oResp.StatusCode & @CRLF)
    ConsoleWrite("Failed." & @CRLF)
    Exit
EndIf

; Success if we get here..
; Save the binary body as the PNG file, or you can get the bytes of the PNG..
$bSuccess = $oResp.SaveBodyBinary("c:/temp/qa_output/qr_code.png")

; Or get the bytes:
$oBd = ObjCreate("Chilkat.BinData")
$oResp.GetBodyBd($oBd)
; Use the bytes in bd...
; See the online reference documentation for the function to access the bytes directly.
