urllib2.HTTPError:HTTP 错误 400:错误请求 - Python [英] urllib2.HTTPError: HTTP Error 400: Bad Request - Python

问题描述

我正在尝试使用 urllib 和 urllib2 进行 POST，但它一直给我这个错误

I'm trying to POST using urllib and urllib2 but it keeps giving me this error

    Traceback (most recent call last):
  File "/Users/BaDRaN/Desktop/untitled text.py", line 39, in <module>
    response = urllib2.urlopen(request)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 127, in urlopen
    return _opener.open(url, data, timeout)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 410, in open
    response = meth(req, response)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 523, in http_response
    'http', request, response, code, msg, hdrs)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 448, in error
    return self._call_chain(*args)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 382, in _call_chain
    result = func(*args)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/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

这是我的代码

body    = {'where' : {'deviceType' : 'ios'}, 'data' : {'alert' : 'vvv'}}
headers = { 'X-Parse-Application-Id' : 'someID', 'X-Parse-REST-API-Key' : 'someKey', 'Content-Type' : 'application/json' }

data     = urllib.urlencode(body)
request  = urllib2.Request('https://api.parse.com/1/push', data, headers)
response = urllib2.urlopen(request)
call     = response.read()

有人可以帮我吗?

推荐答案

我的超能力建议您希望将 body 作为 json 字符串发送，而不是作为转换为字符串的字典发送.

My psychic powers suggest you want to send body as a string of json, not as a dictionary that's converted to a string.

body = '{"where" : {"deviceType" : "ios"}, "data" : {"alert" : "vvv"}}'

注意对 json 元素使用双引号.

Notice the use of double-quotes for the json elements.
