下面的代码有效。但是,如果我注释掉Dim objRequest As MSXML2.XMLHTTP行并取消注释Dim objRequest As Object行,它将失败并显示错误消息:



为什么,我可以做什么(如果有的话)?

Public Function GetSessionId(strApiId, strUserName, strPassword) As String

    Dim strPostData As String

    Dim objRequest As MSXML2.XMLHTTP
    'Dim objRequest As Object '

    strPostData = "api_id=" & strApiId & "&user=" & strUserName & "&password=" & strPassword

    Set objRequest = New MSXML2.XMLHTTP
    With objRequest
        .Open "POST", "https://api.clickatell.com/http/auth", False
        .setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
        .send strPostData
        GetSessionId = .responseText
    End With

End Function

科里,是的,我知道我必须这样做才能使我的代码在不引用MSXML类型库的情况下工作。这不是这里的问题。无论我是否使用Dim objRequest As Object,代码都会失败

带有引用的Set objRequest = NEW MSXML2.XMLHTTP,或者

没有引用的Set objRequest = CreateObject("MSXML2.XMLHTTP")

最佳答案

由于某些原因,这可行:

Dim strPostData As String
Dim objRequest As Object

strPostData = "api_id=" & strApiId & "&user=" & strUserName & "&password=" & strPassword

Set objRequest = New MSXML2.XMLHTTP
With objRequest
  .Open "POST", "https://api.clickatell.com/http/auth", False
  .setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
  .send (strPostData)
   GetSessionId = .responseText
End With

强烈建议您使用URL编码功能,而不是通过字符串连接来构建URL编码的strPostData:
strPostData = "api_id=" & URLEncode(strApiId) & _
              "&user=" & URLEncode(strUserName) & _
              "&password=" & URLEncode(strPassword)

此线程中有VBA中URLEncode()函数的几个选择:How can I URL encode a string in Excel VBA?
