Question

我试图在Python中创建一个POST请求脚本，它会自动将数据发送到数据库。由于我的Web应用程序（在Django中制作）仍在进行中（在localhost上），我试图通过IPv4：port从同一网络上的另一台计算机发送此POST请求。

执行此操作时，我收到HTTP错误500：内部服务器错误，回溯到该行＆＃34; response = urllib2.urlopen（req）＆＃34; 我的脚本看起来像这样：

import urllib, urllib2, cookielib
import re

cookie_jar = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookie_jar))
urllib2.install_opener(opener)

url_1 = 'http://192.168.1.104:8000/legacy'
req = urllib2.Request(url_1)
rsp = urllib2.urlopen(req)


url_2 = 'http://192.168.1.104:8000/legacy'
params = {
    'temperature_max' : '186',
    'temperature_min' : '88',
    'submit': 'Submit',
    }

data = urllib.urlencode(params)
req = urllib2.Request(url_2, data)
response = urllib2.urlopen(req)
the_page = response.read()
pat = re.compile('Title:.*')
print pat.search(the_page).group()

在托管服务器的另一台计算机上，我收到以下错误：

    Exception happened during processing of request from ('192.168.1.65', 56996)
    Traceback (most recent call last):
  File "c:\python27\Lib\SocketServer.py", line 599, in process_request_thread

self._sock.sendall(view[write_offset:write_offset+buffer_size])
error: [Errno 10054] An existing connection was forcibly closed by the remote host

编辑：如果我使用浏览器连接到我的应用程序，我想告诉您我可以将数据从其他计算机发布到我的数据库。

Answer 1

您需要获取会话cookie，然后阅读该会话生成的cookie。

最好的方法是首先使用表单获取页面，保存所有cookie。您可以使用cookielib作为演示here。如果你想让自己的生活更轻松，也可以使用请求而不是urllib。然后代码变为a lot simpler。

要获取CSRF令牌，您可以使用BeautifulSoup抓取表单页面。您可以在Google上轻松找到很多tutorials。

试试：

import urllib.request
from urllib.error import HTTPError

url = "<enter_URL_here>"

try:
   res = urllib.request.urlopen(url)
except HTTPError as e:
    content = e.read()
    print("HTTP error encountered while reading URL")
