我在抓取网页内容时遇到了困难。
在这里解释一下我的Python代码:
response = requests.post('http://a836-acris.nyc.gov/bblsearch/bblsearch.asp?borough=1&block=733&lot=66',{'User-Agent' : 'Mozilla/5.0'})
这为我提供了一个包含表单的HTML页面(不包含最终页面):
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>Untitled Page</title>
</head>
<body>
<form name="bbldata" action="https://a836-acris.nyc.gov/DS/DocumentSearch/BBLResult" method="post">
<input type="hidden" name="hid_borough" value="1"/>
<input type="hidden" name="hid_borough_name" value="MANHATTAN / NEW YORK" />
<input type="hidden" name="hid_block" value="733"/>
<input type="hidden" name="hid_block_value" value="733"/>
<input type="hidden" name="hid_lot" value="66"/>
<input type="hidden" name="hid_lot_value" value="66"/>
<input type="hidden" name="hid_unit" value=""/>
<input type="hidden" name="hid_selectdate" value=""/>
<INPUT TYPE="HIDDEN" NAME="hid_datefromm" VALUE="">
<INPUT TYPE="HIDDEN" NAME="hid_datefromd" VALUE="">
<INPUT TYPE="HIDDEN" NAME="hid_datefromy" VALUE="">
<INPUT TYPE="HIDDEN" NAME="hid_datetom" VALUE="">
<INPUT TYPE="HIDDEN" NAME="hid_datetod" VALUE="">
<INPUT TYPE="HIDDEN" NAME="hid_datetoy" VALUE="">
<input type="hidden" name="hid_doctype" value=""/>
<input type="hidden" name="hid_doctype_name" value="All Document Classes"/>
<input type="hidden" name="hid_max_rows" value="10"/>
<input type="hidden" name="hid_page" value="1" />
<input type="hidden" name="hid_ReqID" value=""/>
<input type="hidden" name="hid_SearchType" value="BBL"/>
<input type="hidden" name="hid_ISIntranet" value="N"/>
<input type="hidden" name="hid_sort" value=""/>
</form>
<script language="JavaScript">
document.bbldata.submit();
</script>
</body>
</html>
但是,如果您在浏览器中输入此网址,则在加载HTML中的脚本后,您最终会获得此网页,并且必须将其删除:
任何帮助将不胜感激!

示例中的HTML表格显示了您需要发布的数据。我认为您已经意识到,您正在使用的网址实际上是 referer 。所以,你需要:
# 1. Create a payload
payload = {
'hid_borough': 1,
'hid_borough_name': 'MANHATTAN / NEW YORK',
'hid_block': 733,
'hid_block_value': 733,
'hid_lot': 66,
'hid_lot_value': 66,
'hid_doctype_name': 'All Document Classes',
'hid_max_rows': 10,
'hid_page': 1,
'hid_SearchType': 'BBL',
'hid_ISIntranet': 'N'
}
# 2. Add the correct referer to your headers
header = {'User-Agent': 'Mozilla/5.0',
'referer': 'http://a836-acris.nyc.gov/bblsearch/bblsearch.asp?borough=1&block=733&lot=66'}
# 3. Add payload and headers to the post
redirect = 'https://a836-acris.nyc.gov/DS/DocumentSearch/BBLResult'
result = requests.post(redirect, data=payload, headers=header)
print result.url
https://a836-acris.nyc.gov/DS/DocumentSearch/BBLResult
