Question

我对用户身份验证缺乏经验，特别是通过restful apis。我正在尝试使用python登录parse.com中设置的用户。以下是我的代码：

  API_LOGIN_ROOT = 'https://api.parse.com/1/login'
  params = {'username':username,'password':password}
  encodedParams = urllib.urlencode(params)

  url = API_LOGIN_ROOT + "?" + encodedParams

  request = urllib2.Request(url)

  request.add_header('Content-type', 'application/x-www-form-urlencoded')

  # we could use urllib2's authentication system, but it seems like overkill for this
  auth_header =  "Basic %s" % base64.b64encode('%s:%s' % (APPLICATION_ID, MASTER_KEY))
  request.add_header('Authorization', auth_header)
  request.add_header('X-Parse-Application-Id', APPLICATION_ID)
  request.add_header('X-Parse-REST-API-Key', MASTER_KEY)

  request.get_method = lambda: http_verb


  # TODO: add error handling for server response
  response = urllib2.urlopen(request)
  #response_body = response.read()
  #response_dict = json.loads(response_body)

这是对用于访问解析休息接口的开源库的修改。

我收到以下错误：

Traceback (most recent call last):

    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
HTTPError: HTTP Error 404: Not Found

有人能指出我搞砸的地方吗？我不太清楚为什么我得到404而不是拒绝访问或其他问题。

Answer 1

确保在Parse.com上创建“User”类作为特殊用户类。添加类时，请确保将类类型更改为“用户”而不是“自定义”。一个小的用户头部图标将显示在左侧的班级名称旁边。

这让我困扰了很长时间，直到Parse团队的Matt向我展示了这个问题。

Answer 2

请将API_LOGIN_ROOT = 'https://api.parse.com/1/login'更改为以下内容：API_LOGIN_ROOT = 'https://api.parse.com/1/login**/**'

我在使用PHP时遇到了同样的问题，最后添加/修复了 404 错误。
