我有要求必須通過代碼登錄網站,然後通過導航到某個位置下載報告文件。我已成功登錄,並且已到達文件下載的URL,但無法自動將其保存到磁盤。 下面是我的代碼使用.net自動下載文件
Imports SHDocVw
Imports mshtml
Imports System.Net
Module Module1
Dim HTMLDoc As HTMLDocument
Dim MyBrowser As InternetExplorer
Sub Main()
MyGmail()
End Sub
Sub MyGmail()
Dim MyHTML_Element As IHTMLElement
Dim MyURL As String
On Error GoTo Err_Clear
MyURL = "https://example.com/"
MyBrowser = New InternetExplorer
MyBrowser.Silent = True
MyBrowser.Navigate(MyURL)
MyBrowser.Visible = True
Do
Loop Until MyBrowser.ReadyState = tagREADYSTATE.READYSTATE_COMPLETE
HTMLDoc = MyBrowser.Document
HTMLDoc.all.txtUserID.Value = "[email protected]" 'Enter your email id here
HTMLDoc.all.txtPassword.Value = "test123" 'Enter your password here
For Each MyHTML_Element In HTMLDoc.getElementsByTagName("input")
If MyHTML_Element.Type = "submit" Then MyHTML_Element.click() : Exit For
Next
'Navigate to reports folder
Dim newReportURL As String
newReportURL = "https://some_static_url_to_navigate"
MyBrowser.Navigate(newReportURL)
Dim i As Integer
Dim reportURL As String
reportURL = ""
i = 0
For Each MyHTML_Element In HTMLDoc.getElementsByTagName("a")
If DirectCast(MyHTML_Element, mshtml.IHTMLAnchorElement).innerText = "Export" And i = 1 Then
reportURL = DirectCast(MyHTML_Element, mshtml.IHTMLAnchorElement).href
End If
If DirectCast(MyHTML_Element, mshtml.IHTMLAnchorElement).innerText = "Export" Then
i = i + 1
End If
Next
MyBrowser.Navigate(reportURL)
For Each MyHTML_Element In HTMLDoc.getElementsByTagName("input")
If MyHTML_Element.Type = "submit" Then
MyHTML_Element.click() : Exit For
End If
Next
Dim xlsReportURL As String
xlsReportURL = DirectCast(MyBrowser.Document, mshtml.IHTMLDocument).url
Err_Clear:
If Err.Number <> 0 Then
Err.Clear()
Resume Next
End If
End Sub
End Module
最後一個變量xlsReportURL包含我的報告的網址是.xls格式。我如何將此報告直接保存到我的硬盤上?
你的C#似乎有點從一個我所知道的區別。 – Vladimirs
我的錯誤..其實它vb .net – Tweety01
此代碼看起來像Visual Basic,但不是c# –
