urllib2.HTTPError: HTTP Error 400: Bad Request - Python
我正在尝试 POST 使用 urllib 和 urllib2，但它一直给我这个错误

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？
我的通灵能力建议您将 body 作为 json 的字符串发送，而不是作为转换为字符串的字典发送。
body = '{"where" : {"deviceType" : "ios"}, "data" : {"alert" : "vvv"}}'
注意 json 元素使用双引号。
我怀疑您的负载编码不正确。他们没有说 "urlencoded"。尝试改用他们自己的示例。 https://parse.com/docs/rest#push urrlib2 是一个相当原始的库 - 使用例如请求会更方便。
这取决于json数据格式是否正确，或者问题出在header内容上。因此 urllib2.HTTPError: HTTP Error 400: Bad Request 通常会发生。
下面的一小段代码，带有 headers 的 basic64 身份验证和 PUT/POST 方法的 json 数据：
import urllib2
import base64
import json
url = 'Your_URL'
auth = 'Basic ' + base64.encodestring('%s:%s' % ('username','password'))[:-1]
content_header = {'Authorization': auth,
'Content-Type':'application/json',
'Accept':'application/json'}
json_data = YOUR_DATA
request = urllib2.Request(url=url, data=json.dumps(json_data), headers=content_header)
request.get_method = lambda: 'PUT' #If you will not provide this, then it will be POST
response = urllib2.urlopen(request)
