HTTP错误500：内部服务器错误

I'm trying to make a POST request script in Python which will send data to database automatically. Since my web application (made in Django) is still in progress (on localhost) I tried to send this POST request from another computer on same network via IPv4:port.

我正在尝试在Python中创建一个POST请求脚本,它将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。

While doing this I get HTTP Error 500: Internal server error with traceback to the line "response = urllib2.urlopen(req)" My script looks like this:

执行此操作时,我收到HTTP错误500:内部服务器错误,回溯到“response = urllib2.urlopen(req)”行我的脚本如下所示:

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()

On the other computer that is hosting the server I get the following error:

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):

error: [Errno 10054] An existing connection was forcibly closed by the remote host

EDIT: I'd like to let you know that I can post data from the other computer to my database if I connect to my app with my browser.

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

You will need to get a session cookie and then read the generated cookie for that session.

您需要获取会话cookie,然后阅读该会话生成的cookie。

The best way to go about that is to fetch the page with the form first, saving all cookies. You can use cookielib for that as demonstrated here. If you want to make life easier for yourself, use requests as well instead of urllib. The code then becomes a lot simpler.

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,如此处所示。如果你想让自己的生活更轻松,也可以使用请求而不是urllib。然后代码变得简单得多。

To get the CSRF token, you can scrape the form page with BeautifulSoup. There are lots of tutorials for this which you can easily find on Google.

要获取CSRF令牌,您可以使用BeautifulSoup刮取表单页面。有很多教程可以在Google上轻松找到。
