Python使用请求提交web表单

Question

所以我需要使用python抓取这个网站，但是我在尝试提交表单时发现了一个问题。我得到的响应是与表单相同的页面，而不是提交表单后的结果。我尝试使用请求library/ mechanize / urllib。

带有请求的代码:

url = "http://www.justiceservices.gov.mt/courtservices/Judgements/search.aspx?func=selected"
payload = {'ctl00$ContentPlaceHolderMain$search_selected_panel$tb_date_from':'',
           'ctl00$ContentPlaceHolderMain$search_selected_panel$tb_date_to':'',
           'ctl00$ContentPlaceHolderMain$search_selected_panel$dd_court':108,
           'ctl00$ContentPlaceHolderMain$search_selected_panel$dd_judiciary':'',
           'ctl00$ContentPlaceHolderMain$search_selected_panel$tb_litigant1':'',
           'ctl00$ContentPlaceHolderMain$search_selected_panel$tb_litigant2':'',
           'ctl00$ContentPlaceHolderMain$search_selected_panel$tb_keywords':'',
           'ctl00$ContentPlaceHolderMain$search_selected_panel$keywords':'rb_keywords_matching_all',                    
           'ctl00$ContentPlaceHolderMain$search_selected_panel$bt_search':'Search',
           'ctl00$ContentPlaceHolderMain$search_selected_panel$result_count_panel$dd_result_count':10}
headers = {'content-type': 'application/x-www-form-urlencoded'}
r = requests.post(url,payload,allow_redirects=True)
print r.headers
print r.text

我需要张贴额外的数据吗?或者我的方法是错误的形式的类型。

如果您查看请求源，特别是https://github.com/kennethreitz/requests/blob/master/requests/api.py#L80，您将看到该帖子忽略了args。如果没有时间进行测试，您可能需要这样做:

r = requests.post(url, data=payload, allow_redirects=True
