Question

我正在尝试发送http请求，但我总是得到http错误400

我该怎么办？

这是代码：

def login(params):
    url = "https://cps-inbararan.c9users.io/DBI/listener.php?func_name=%s&params=%s"%("exists_user",json.dumps(params))
    ans = urllib2.urlopen(url).read()
    return ans.split("::")[0]

这是错误

   Traceback (most recent call last):
File "UMC_Handler.py", line 22, in <module>
  ans = uf.login(params)
File "/home/ubuntu/workspace/UMC_func.py", line 60, in login
  ans = urllib2.urlopen(url).read()
File "/usr/lib/python2.7/urllib2.py", line 127, in urlopen
  return _opener.open(url, data, timeout)
File "/usr/lib/python2.7/urllib2.py", line 410, in open
  response = meth(req, response)
File "/usr/lib/python2.7/urllib2.py", line 523, in http_response
  'http', request, response, code, msg, hdrs)
File "/usr/lib/python2.7/urllib2.py", line 448, in error
  return self._call_chain(*args)
File "/usr/lib/python2.7/urllib2.py", line 382, in _call_chain
  result = func(*args)
File "/usr/lib/python2.7/urllib2.py", line 531, in http_error_default
  raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 400: Bad request
