我试图通过一个简单的 python 代码提交我的解决方案，该代码使用我的用户名、密码、文件名、语言选择和问题代码代表我将解决方案提交给 spoj。

到目前为止，我已经走了，

import httplib,urllib
import urllib2
params=urllib.urlencode({'login_user':'username','password':'yourpassword','lang':'C (gcc 4.3.2)','problemcode':'TEST','subm_file':'/home/mj/code/uu.c'})
headers={"Content-type": "multipart/form-data"}
req=urllib2.Request("http://www.spoj.com/submit/",params)
thepage=urllib2.urlopen(req)
data=thepage.read()
newf=open("wer.html","w")
newf.write(data)
newf.close()`

我期望显示“已提交解决方案”，但我得到了需要授权。但是当我尝试登录时，它确实如此。

有没有办法在登录后输入提交，即我正在使用的 POST 方法应该在它成功登录的页面上恢复，换句话说，python 中有没有办法“记住”“我已经登录”成功，现在让我提交问题”，这样就不会看到“需要授权”提示。

您提交文件的方法不正确。您传递的是带有文件名的字符串，而不是实际文件作为subm_file. 您需要发布文件的内容。

我个人使用posterPOST 文件：http ://atlee.ca/software/poster/

这是一个相关的 SO 问题：Send file using POST from a Python script

另外，查看源代码，我认为您想将其发布到http://www.spoj.com/submit/complete/，而不是.../submit/. .../submit/是左侧登录表单的操作。.../submit/complete/是表单提交代码的动作。

您params没有使用Content-type "multipart/form-data". 我尝试使用"application/x-www-form-urlencoded"内容类型发送请求，它可以工作：

#!/usr/bin/env python
import re
import webbrowser
from netrc import netrc
from urllib import urlencode, quote
from urllib2 import urlopen

user, _, password = netrc().authenticators('spoj.com')  # read from ~/.netrc
r = urlopen("https://www.spoj.com/submit/complete/",  # no certificate test
            data=urlencode(dict(
            login_user=user,
            password=password,
            problemcode="TEST",  # problem id
            lang="116",  # Python 3 (see languages below)
            submit="Send",
            file="for s in iter(input, '42'): print(s)")))
m = re.search(r'"newSubmissionId" value="(\d+)"/>', r.read())  # XXX dirty
print("submission id %d" % int(m.group(1)))
webbrowser.open("https://www.spoj.com/status/%s/" % quote(user))
