i think something mess with inetget cause this problem

can you help me please?

$sAdditionalData = "secret_key=" & $secret_key_verify & "&slm_action=slm_check&license_key=" & $license_key&"&first_name="&$first_name
$data = _INetGetSource($sDomain&'/?'&$sAdditionalData)
$object = json_decode($data)
$response = json_get($object, '.first_name')

Most browsers will try to properly encode a URL before sending it.  As you have found out, the _InetGetSource() function does not do any special encoding of your URL.  Therefore, you must make sure that your URL is properly encoded before sending it.  The example below shows one of many functions (_UnicodeURLEncode) that can be used to encode all or part of a URL.  You can find another example in the topic below.  If you are building URLs dynamically, it's probably a good idea to encode the URL whether you think you need to or not.




#AutoIt3Wrapper_AU3Check_Parameters=-w 3 -w 4 -w 5 -w 6 -d

#include <Constants.au3>
#include <Inet.au3>
#include <Debug.au3>
#include <json.au3>


Func example()
    Local $sEncodedRequest, $sRespone, $sJson
    Local $oJson

    Const $REQUEST = "https://postman-echo.com/get?first_name=سلام"

    _DebugSetup(Default, False, 5)

    ;Encode & display the URL
    $sEncodedRequest = _UnicodeURLEncode("https://postman-echo.com/get?first_name=سلام")

    _DebugOut("HTTP Request (Raw)     = " & $REQUEST)
    _DebugOut("HTTP Request (Encoded) = " & $sEncodedRequest)

    ;Send HTTP GET request
    $sRespone = _INetGetSource($sEncodedRequest, False)
    If @error Then Exit MsgBox($MB_ICONERROR + $MB_TOPMOST, "ERROR", "_INetGetSource failed! @error = " & @error)

    ;Decode JSON response
    $oJson = Json_Decode(BinaryToString($sRespone, $SB_UTF8))
    If @error Then Exit MsgBox($MB_ICONERROR + $MB_TOPMOST, "ERROR", "Unable to decode response. @error = " & @error)

    ;Display pretty-printed response (unicode and slashes are unescaped)

    _DebugOut(@CRLF & "JSON Response (unicode and slashes are unescaped)")

; _UnicodeURLEncode()
; Description: : Encodes an unicode string to be URL-friendly
; Parameter(s): : $UnicodeURL - The Unicode String to Encode
; Return Value(s): : The URL encoded string

Func _UnicodeURLEncode($UnicodeURL)
    Local $UnicodeBinary = StringToBinary ($UnicodeURL, 4)
    Local $UnicodeBinary2 = StringReplace($UnicodeBinary, '0x', '', 1)
    Local $UnicodeBinaryLength = StringLen($UnicodeBinary2)
    Local $UnicodeBinaryChar
    Local $EncodedString
    For $i = 1 To $UnicodeBinaryLength Step 2
        $UnicodeBinaryChar = StringMid($UnicodeBinary2, $i, 2)
        If StringInStr("$-_.+!*'(),;/?:@=&abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890", BinaryToString ('0x' & $UnicodeBinaryChar, 4)) Then
            $EncodedString &= BinaryToString ('0x' & $UnicodeBinaryChar)
            $EncodedString &= '%' & $UnicodeBinaryChar
    Return $EncodedString

Example output

HTTP Request (Raw)     = https://postman-echo.com/get?first_name=سلام
HTTP Request (Encoded) = https://postman-echo.com/get?first_name=%D8%B3%D9%84%D8%A7%D9%85

JSON Response (unicode and slashes are unescaped)
   "args": {
