Question

这是网站“ https://www.interlinecenter.com/”，该网站正在向“ http://cs.cruisebase.com/cs/forms/hotdeals.aspx?skin=605&nc=y”发出请求，以将HTML内容加载到“ I-FRAME”中。我正在使用浏览器发送的相同标头发出完全相同的请求，但是我没有获得相同的内容。

这是我正在使用的代码：

url='http://cs.cruisebase.com/cs/forms/hotdeals.aspx?skin=605&nc=y'

header = {

'Cache-Control': 'max-age=0'
}

response = requests.get(url, timeout=10, headers=header)

byte_data = response.content 
source_code = html.fromstring(byte_data)
print(response)
print(byte_data)

这是我得到的答复：

<Response [200]>
<html style="height:100%"><head><META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"><meta name="format-detection" content="telephone=no"><meta name="viewport" content="initial-scale=1.0"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"></head><body style="margin:0px;height:100%"><iframe id="main-iframe" src="/_Incapsula_Resource?SWUDNSAI=9&xinfo=10-99927380-0%200NNN%20RT%281575456049298%202%29%20q%280%20-1%20-1%200%29%20r%281%20-1%29%20B12%284%2c316%2c0%29%20U2&incident_id=500000240101726326-477561257670738314&edet=12&cinfo=04000000&rpinfo=0" frameborder=0 width="100%" height="100%" marginheight="0px" marginwidth="0px">Request unsuccessful. Incapsula incident ID: 500000240101726326-477561257670738314</iframe></body></html>

我需要在“ https://cs.cruisebase.com/cs/forms/hotdeals.aspx?skin=605&nc=y”处提取/抓取数据。

注意：我不想使用Selenium Webdriver来获取数据，任何帮助将不胜感激，谢谢！

您是否尝试通过直接加载目标URL来获取标题？

我向https://cs.cruisebase.com/cs/forms/hotdeals.aspx?skin=605&nc=y发送了一个带有以下标头的GET请求，并获得了完整的响应。

headers = { 
'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3',
'Accept-Encoding':'gzip, deflate',
'Accept-Language':'en-GB,en;q=0.9,en-US;q=0.8,hi;q=0.7,la;q=0.6',
'Cache-Control':'no-cache',
'Connection':'keep-alive',
'Cookie':'ENTER COOKIES',
'DNT':'1',
'Host':'cs.cruisebase.com',
'Pragma':'no-cache',
'Upgrade-Insecure-Requests':'1',
'User-Agent':'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36',
 }

我将Cookie字段留为空白，您将必须输入Cookie，否则该页面将无法加载。您可以从Chrome浏览器获取Cookie。

当我复制浏览器发出的确切请求时，为什么会被检测为机器人？
