我试图在VBA环境(Excel)上使用MSXML2.XMLHTTP对象从网站上废弃数据,我无法弄清楚如何解决这个问题!该网站如下:
http://www.detran.ms.gov.br/consulta-de-debitos/
你们可以使用以下测试数据填写表格:
我想检索像" chassi"这样的数据,上面的数据是" 9BD374121F5068077"
我在解析html文档时没有问题,实际上很难将信息作为响应获取!代码如下:
Sub SearchVehicle()
Dim strPlaca As String
Dim strRenavam As String
strPlaca = "oon5868"
strRenavam = "01021783231"
Dim oXmlPage As MSXML2.XMLHTTP60
Dim strUrl As String
Dim strPostData As String
Set oXmlPage = New MSXML2.XMLHTTP60
strUrl = "http://www2.detran.ms.gov.br/detranet/nsite/veiculo/veiculos/retornooooveiculos.asp"
strPostData = "placa=" & strPlaca & "&renavam=" & strRenavam
oXmlPage.Open "POST", strUrl, False
oXmlPage.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
oXmlPage.send strPostData
Debug.Print oXmlPage.responseText
End Sub
POST方法中使用的strURL" ... / retornooooveiculos.asp"是一个谷歌开发者工具和小提琴手告诉我,这是网站发布有效载荷的正确地址。
手动访问时,网站会检索正确的信息,但运行我的代码我总是在.responseText上得到以下响应:
<html>Acesse: <b><a href='http://www.detran.ms.gov.br target='_parent'>www.detran.ms.gov.br</a></b></html>
请帮助,我疯狂地试图解决这个难题!为什么我会像这样重定向?
我需要&#34; CHASSI&#34;信息,无法找到正确的http请求!
答案 0 :(得分:1)
尝试以下方法。它应该为您提取您所追求的内容。问题是您需要提供从Cookie
字段复制的Request Headers
,以便您的脚本可以使用devtools找到。
Sub SearchVehicle()
Const URL As String = "http://www2.detran.ms.gov.br/detranet/nsite/veiculo/veiculos/retornooooveiculos.asp"
Dim HTTP As New ServerXMLHTTP60, HTML As New HTMLDocument
Dim elem As Object, splaca$, srenavam$, qsp$
splaca = "oon5868"
srenavam = "01021783231"
qsp = "placa=" & splaca & "&renavam=" & srenavam
With HTTP
.Open "POST", URL, False
.setRequestHeader "User-Agent", "Mozilla/5.0"
.setRequestHeader "Cookie", "ISAWPLB{07D08995-E67C-4F44-91A1-F6A16337ECD6}={286E0BB1-C5F9-4439-A2CE-A7BE8C3955E0}; ASPSESSIONIDSCSDSCTB=AGDPOBEAAPJLLMKKIGPLBGMJ; 69137927=967930978"
.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
.send qsp
HTML.body.innerHTML = .responseText
End With
For Each elem In HTML.getElementsByTagName("b")
If InStr(elem.innerText, "Chassi:") > 0 Then MsgBox elem.ParentNode.NextSibling.innerText: Exit For
Next elem
End Sub
再次:使用您的devtools(来自Cookie
部分)收集Request Headers
字段,如果由于某种原因我提供的Cookie
不适合您。感谢。
我得到的输出:
