我正在写一个独立的机器人，登录JitJat，一个匿名的即时消息站点，并向用户发送消息。我成功地做到了这一点，我到达了the index，在那里我选择了我的收件人。
最后，我可以在the chat与某人聊天，但每当我尝试获取页面的形式时，我都会得到无。我尝试使用robobrowser，requests和mechanicalsoup多次这样做。
我的脚本在这里：
import mechanicalsoup
#Current url: https://jitjat.org/login.php
browser = mechanicalsoup.StatefulBrowser()
browser.open('https://jitjat.org/login.php')
print('Current url: ' + str(browser.get_url()))
browser.select_form()
browser['username'] = 'my username'
browser['password'] = 'my password'
browser.submit_selected()
print('Redirect: ' + str(browser.get_url()))
#Current url: https://jitjat.org/index.php
browser.follow_link("recipient username")
print('Redirect: ' + str(browser.get_url()))
#Current url: https://jitjat.org/chat.php?id=(recipient username)
browser.select_form()
print(browser.get_current_form().print_summary())
这里的页面来源：

</html>我解决了这个问题。对于所有那些有类似问题的人，由于特定的html代码，我建议使用robobrowser，一个智能的跨平台模块（有用的文档here）。
如果由于某种原因你无法获得页面的形式：
browser = RoboBrowser(id='FormId')import requests
mysession = requests.session()
open = mysession.get('website_url')
print(open.headers)
像这样添加标题：
mysession.headers = open.headers
browser = RoboBrowser(id='FormId', session=mysession, history=True)希望能帮助到你！
