我使用rest api发送推送通知。 文档are here. 我使用金字塔并使用芹菜安排这些推送通知。
这是我的代码示例:
result = urllib2.urlopen(urlRequest, headers={
"X-Parse-Application-Id": settings["parse.application.id"],
"X-Parse-REST-API-Key": settings["parse.restapi.key"],
"Content-Type": "application/json"
})
connection = httplib.HTTPSConnection('api.parse.com', 443)
connection.connect()
connection.request('POST', '/1/push', json.dumps(data), )
result = json.loads(connection.getresponse().read())
但是芹菜记录了这个错误:

有什么问题?
答案 0 :(得分:6)
urllib2.urlopen
没有名为headers
的参数:
urllib2.urlopen :( url,data = None,timeout = socket._GLOBAL_DEFAULT_TIMEOUT)
打开URL网址,可以是字符串或请求对象。
使用urllib2.Request
传递headers
:
req = urllib2.Request(url, headers={
"X-Parse-Application-Id": settings["parse.application.id"],
"X-Parse-REST-API-Key": settings["parse.restapi.key"],
"Content-Type": "application/json"
})
result = urllib2.urlopen(req)
答案 1 :(得分:3)
<强>问题强>
方法urllib2.urlopen
没有headers
参数。这是错误消息
TypeError:urlopen()得到了一个意外的关键字参数&#39; headers&#39;
<强>解决方案强>
connection.request
是您定义headers
。
