我在抓取网页内容方面遇到困难。

为了解释这是我的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'})

这给了我一个包含表单(不包含最终页面)的HTML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,如果在浏览器中输入了这个URL,那么最终在HTML中的脚本加载完成后,你将获得此网页,并且必须对其进行修改:

# 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
