以下是使用VBA编写基本的爬虫代码,并包含了Host、Referer、User-Agent和Cookie请求头:
```
Sub webScraping()
Dim xmlHttp As Object
Dim htmlDoc As Object
Dim url As String
Dim headers As String
' 设置请求URL和请求头信息
url = "https://example.com"
headers = "Host: example.com" & vbCrLf & _
"Referer: https://www.google.com/" & vbCrLf & _
"User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3" & vbCrLf & _
"Cookie: SESSIONID=1234567890abcdef"
' 创建XMLHttpRequest对象
Set xmlHttp = CreateObject("MSXML2.XMLHTTP")
' 发送GET请求
xmlHttp.Open "GET", url, False
xmlHttp.setRequestHeader "Content-Type", "text/plain;charset=UTF-8"
xmlHttp.setRequestHeader "Connection", "keep-alive"
xmlHttp.setRequestHeader "Accept-Language", "en-US,en;q=0.9"
xmlHttp.setRequestHeader "Accept-Encoding", "gzip, deflate, br"
xmlHttp.setRequestHeader "Cache-Control", "max-age=0"
xmlHttp.setRequestHeader "Upgrade-Insecure-Requests", "1"
xmlHttp.setRequestHeader "Pragma", "no-cache"
xmlHttp.setRequestHeader "DNT", "1"
xmlHttp.setRequestHeader "Sec-Fetch-Site", "none"
xmlHttp.setRequestHeader "Sec-Fetch-Mode", "navigate"
xmlHttp.setRequestHeader "Sec-Fetch-User", "?1"
xmlHttp.setRequestHeader "Sec-Fetch-Dest", "document"
xmlHttp.setRequestHeader "Sec-Ch-Ua", """Google Chrome"";v=""93"", "" Not;A Brand"";v=""99"", ""Chromium"";v=""93"""
xmlHttp.setRequestHeader "Sec-Ch-Ua-Mobile", "?0"
' 添加自定义请求头
xmlHttp.setRequestHeader "Host", "example.com"
xmlHttp.setRequestHeader "Referer", "https://www.google.com/"
xmlHttp.setRequestHeader "User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3"
xmlHttp.setRequestHeader "Cookie", "SESSIONID=1234567890abcdef"
' 发送请求并获取响应
xmlHttp.send
' 解析响应内容
Set htmlDoc = CreateObject("HTMLfile")
htmlDoc.body.innerHTML = xmlHttp.responseText
' 输出响应结果
Debug.Print htmlDoc.body.innerHTML
End Sub
```
请注意,上述示例代码仅供参考,并且具体的请求头信息需要根据实际情况进行调整。同时,还需要注意网站是否允许爬虫访问,否则可能会触发反爬虫机制。
