WinHttp.WinHttpRequest.5.1 URL ENCODE

Question

我正在尝试使用Qrickt API：https://qrickit.com/qrickit_apps/qrickit_api.php

在VBA中为Google Map地址创建QRCode。为此，我必须发送这样的Http请求：

"http://qrickit.com/api/qr.php?d=http://google.com/maps?q=Via+Roma,+1+Milano&qrsize=150&t=p&e=m"

API文档说：

**对于非英文和特殊字符，请先对数据进行url编码。

问题是我无法设法将编码的地址传递给API。如果我传递“ Via + Roma”或“ Via％20Roma”之类的字符串，则生成的QRCode URL始终为

http://maps.google.com/maps?q=Via Roma, 1 Milano

因此创建了QRCode图像，但电话无法直接打开Goog​​le地图。

有人可以帮我吗？

这是代码：

Public Function f_QRCode(ByVal Address As String, ByVal Destination As String) As Boolean

On Error GoTo Err_Handler

Const ApiPath As String = "https://qrickit.com/api/qr.php?d=http://maps.google.com/maps?q="
Dim WinHttpReq As Object  '\\     Oggetto che serve al download del verbale
Dim fic As Integer
Dim buffer() As Byte
Dim URL As String

'\\ Costruisco l'URL
    URL = ApiPath + "Via%20Roma%2C%%201%20Milano" + "&qrsize=150&t=p&e=m"

    '\\ Creo l'oggetto per la connessione
   Set WinHttpReq = CreateObject("WinHttp.WinHttpRequest.5.1")

   WinHttpReq.Open "POST", URL, False
   WinHttpReq.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"

   WinHttpReq.send

   If WinHttpReq.Status = 200 Then
      fic = FreeFile
      Open Destination For Binary Lock Read Write As #fic
      buffer = WinHttpReq.responseBody
      Put #fic, , buffer

      Close #fic
      f_QRCode = True
    Else
        MsgBox "Error"
    End If

ExitHere:
   Erase buffer
   Set WinHttpReq = Nothing
   Exit Function

Err_Handler:

    Resume ExitHere

End Function

Answer 1

他们的API接受GET请求，并且您正在发送POST。

尝试：

URL = ApiPath + "Via%20Roma%2C%%201%20Milano" + "&qrsize=150&t=p&e=m"

Set WinHttpReq = CreateObject("WinHttp.WinHttpRequest.5.1")

WinHttpReq.Open "GET", URL, False
WinHttpReq.send

Answer 2

我要补充一点，您可以考虑使用函数EncodeURL进行编码。

Application.EncodeURL("url")
