通过 MS-Access 中的 VBA 进行 Google 搜索

Question

以下代码片段搜索与谷歌搜索公司名称。 此代码在 excel 中工作：

    Dim el                      As Object
    Dim http                    As Object
    Dim html                    As New HTMLDocument
    
    Dim lng_row_start As Long
    Dim lng_row As Long
    Dim lng_row_new As Long
    Dim int_column_name As Integer
    Dim int_column_news As Integer
    
    Set http = CreateObject("MSXML2.XMLHTTP")
    '------------
    str_sheet = "news"
    lng_row_start = 3
    int_column_name = 1
    int_column_news = 3
    '------------
    lng_row = lng_row_start
    lng_row_new = lng_row_start
    Do While 0 < Len(Sheets(str_sheet).Cells(lng_row, int_column_name).Value)
    
        str_google = Replace(Sheets(str_sheet).Cells(lng_row, int_column_name).Value, " ", "+")
        http.Open "GET", "https://www.google.com/search?q=" & str_google & "&tbm=nws", False
        http.send
        html.body.innerHTML = http.responseText
        '--------
        Set el = html.getElementById("rso")

现在我想在访问中做到这一点。 使用 XMLHTTP 在“http.send”行上给了我“没有权限”-错误。 使用 ServerXMLHTTP 给我一个 responseText 说我得到了“错误 403。客户端无权获取 url”。

现在我为 ServerXMLHTTP 添加了这一行：

http.setRequestHeader "User-Agent", "Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1)"

现在我得到一个 responseText 说一些关于“登录/登录”的内容。 我是德国人，所以它告诉我“Anmelden”。

所以我仍然无法获得谷歌搜索结果。

一些想法？ 也许我如何获得正确的 requestHeader 所以我没有得到“登录”响应文本？

我使用 ms-access 2007-20016。

以下是我的访问代码片段：

    Dim str_google      As String
    Dim el2             As New HTMLDocument
    Dim el3             As New HTMLDocument
    Dim el4             As New HTMLDocument
    Dim el              As New HTMLDocument
    Dim http            As Object
    Dim html            As New HTMLDocument
    Dim db              As DAO.Database
    Dim rs_companies    As DAO.Recordset
    Dim rs_news         As DAO.Recordset

    Set db = CurrentDb
    Set rs_companies = db.OpenRecordset("SELECT DISTINCT companyName FROM qGoogleSearch")
    Set rs_news = db.OpenRecordset("SELECT * FROM Tnews")
    'Set http = CreateObject("MSXML2.XMLHTTP.6.0")
    Set http = CreateObject("MSXML2.ServerXMLHTTP.6.0")
'ALGORITHM
    rs_companies.MoveFirst
    Do While Not rs_companies.EOF
    
        str_google = "https://www.google.com/search?q=" & _
                    Replace(rs_companies.Fields("companyName").Value, " ", "+") & _
                    "&tbm=nws"
        'http.SetOption 2, 13056
        http.Open "GET", str_google, False
        'http.setRequestHeader "User-Agent", "Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1)"
        http.send
        html.body.innerHTML = http.responseText
        
        Set el = html.getElementById("rso")

编辑：使用这个 url 作品： https://www.google.com/search?q=bango+plc

这确实给出了权限错误： excel 中的 https://www.google.com/search?q=bango+plc&tbm=nws它工作正常...

为什么 XMLHTTP 可以在 excel 中工作，但不能在访问中工作？ 我试图将 msaccess 文件放在受信任的位置。 不工作

Answer 1

除非脚本主机是可信的，否则 XMLHTTP（客户端对象）不允许访问远程对象（病毒）。 因此，Access 出现权限错误的原因是它没有告诉 XMLHTTP 它拥有该权限。

我不太了解 XMLHTTP 信任设置。 看看信任中心（访问）是否有帮助。

更新试试这个并报告：

这对我有用：

Set FSO = CreateObject("Scripting.FileSystemObject")

Set File = FSO.CreateTextFile("C:\Foobar.html",True)
File.Write cstr(http("GET", "https://www.google.com/search?q=bango+plc&tbm=nws", "text/html; charset=UTF-8", "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9", ""))
