推荐答案

除了 Mechanize 和 Selenium David 提到的，也可以通过 请求 和 BeautifulSoup.

Aside from Mechanize and Selenium David has mentioned, it can also be achieved with Requests and BeautifulSoup.

为了更清楚，使用 Requests 向服务器发送请求和从服务器检索响应，并使用 BeautifulSoup 解析响应 html 以了解要发送给服务器的参数服务器.

To be more clear, use Requests to send request to and retrieve responses from server, and use BeautifulSoup to parse the response html to know what parameters to send to the server.

这是我编写的示例脚本，它使用 Requests 和 BeautifulSoup 提交用户名和密码以登录维基百科:

Here is an example script I wrote that uses both Requests and BeautifulSoup to submit username and password to login to wikipedia:

import requests
from bs4 import BeautifulSoup as bs


def get_login_token(raw_resp):
    soup = bs(raw_resp.text, 'lxml')
    token = [n['value'] for n in soup.find_all('input')
             if n['name'] == 'wpLoginToken']
    return token[0]

payload = {
    'wpName': 'my_username',
    'wpPassword': 'my_password',
    'wpLoginAttempt': 'Log in',
    #'wpLoginToken': '',
    }

with requests.session() as s:
    resp = s.get('http://en.wikipedia.org/w/index.php?title=Special:UserLogin')
    payload['wpLoginToken'] = get_login_token(resp)

    response_post = s.post('http://en.wikipedia.org/w/index.php?title=Special:UserLogin&action=submitlogin&type=login',
                           data=payload)
    response = s.get('http://en.wikipedia.org/wiki/Special:Watchlist')

更新:

对于您的具体情况，以下是工作代码:

For your specific case, here is the working code:

import requests
from bs4 import BeautifulSoup as bs


def get_session_id(raw_resp):
    soup = bs(raw_resp.text, 'lxml')
    token = soup.find_all('input', {'name':'survey_session_id'})[0]['value']
    return token

payload = {
    'f213054909': 'o213118718',  # 21st checkbox
    'f213054910': 'Ronald',  # first input-field
    'f213054911': '[e-mail]',
    }

url = r'https://app.e2ma.net/app2/survey/39047/213008231/f2e46b57c8/?v=a'

with requests.session() as s:
    resp = s.get(url)
    payload['survey_session_id'] = get_session_id(resp)
    response_post = s.post(url, data=payload)
    print response_post.text
