我想使用能够填写表单和处理重定向的python库:
{'username':'user', 'password':'pass'}
{'Field 1':'Data 1', 'Field 2':'Data 2'}
我想进入“最终”页面并填写表格。我已经查看了python-requests中SO的每个帖子,阅读了API文档和整个用户指南。
我已经能够使用mechanize来填写“主页”表单:
import mechanize
# Fill out Log In form
br = mechanize.Browser()
br.open('http://www.yourfavoritesite.com')
br.select_form(nr=0)
br['username'] = 'user'
br['password'] = 'pass'
br.submit()
此外 - 在禁用网页上的重定向后 - 我已经能够使用mechanize填写“新”页面表单:
# Click link
br.find_link(text='Admin')
req = br.click_link(text='Admin')
br.open(req)
# Fill out Final form
br.select_form(nr=0)
br['Field 1'] = 'Data 1'
br['Field 2'] = 'Data 2'
br.submit()
如果我不禁用重定向和页面重定向会发生什么,我不会进入“新”页面,当我尝试填写表单时出现以下错误:
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/mechanize/_mechanize.py", line 524, in select_form
raise FormNotFoundError("no form matching "+description)
mechanize._mechanize.FormNotFoundError: no form matching nr 0
我听说Python请求非常简单,我想使用这个库,假设我可以按照以下方式做一些事情:
import requests
# Fill out Log In form
data = {'username':'admin', 'password':'pass'}
r = requests.get('http://www.yourfavoritesite.com', allow_redirects=True)
r = requests.put(r.url, data=data)
# Follow redirect to "new" page
# Click link
# I haven't heard of this feature in requests
# Fill out Final form
data = {'Field 1':'Data 1', 'Field 2':'Data 2'}
r = requests.put(r.url, data=data)
答案 0 :(得分:1)
我知道这已经过时了,但我相信您在requests
寻找的答案(显然)不是get
,而是post
。
自: http://docs.python-requests.org/en/latest/user/quickstart/#more-complicated-post-requests
>>> payload = {'key1': 'value1', 'key2': 'value2'}
>>> r = requests.post("http://httpbin.org/post", data=payload)
>>> print r.text
{
...
"form": {
"key2": "value2",
"key1": "value1"
},
...
}
