[英]Google Cloud Messaging HTTP Error 400: Bad Request
我正在嘗試通過GCM(Google雲消息傳遞)發送消息。 我已通過Google API注冊,我可以從多個Android測試手機向我的網站(這是一個Google App Engine后端)發送一個regID。 但是,我無法從Google App Engine向GCM發送任何內容。 這是我想要使用的。
regId = "APA91b..."
json_data = {"collapse_key" : "Food-Promo", "data" : {
"Category" : "FOOD",
"Type": "VEG",
}, "registration_ids": [regId],
}
url = 'https://android.googleapis.com/gcm/send'
apiKey = "AI..."
myKey = "key=" + apiKey
headers = {'Content-Type': 'application/json', 'Authorization': myKey}
data = urllib.urlencode(json_data)
data2 = {"title": title}
data3 = urllib.urlencode(data2)
req = urllib2.Request(url, data, headers)
f = urllib2.urlopen(req)
response = f.read()
f.close()
logging.debug("***!!!!!!!WriteEntry TEST ----- Response: " + response)
這是我收到的錯誤。

謝謝!
data2和data3用於什么? 你發布的數據不是正確的json所以你需要使用json.dumps(data).Code應該是這樣的:
json_data = {"collapse_key" : "Food-Promo", "data" : {
"Category" : "FOOD",
"Type": "VEG",
}, "registration_ids": [regId],
}
url = 'https://android.googleapis.com/gcm/send'
apiKey = "AI..."
myKey = "key=" + apiKey
data = json.dumps(json_data)
headers = {'Content-Type': 'application/json', 'Authorization': myKey}
req = urllib2.Request(url, data, headers)
f = urllib2.urlopen(req)
response = json.loads(f.read())
reply = {}
if response ['failure'] == 0:
reply['error'] = '0'
else:
response ['error'] = '1'
return HttpResponse(json.dumps(reply), mimetype="application/javascript")
嘗試使用python-gcm 。 它也可以處理錯誤。
以下是我最終解決問題的方法,但上述方法也適用。
def sendGCM(self, regid, email, entry_id, date_modified, kind):
url = 'https://android.googleapis.com/gcm/send'
apiKey = _MY_API_KEY
myKey = "key=" + apiKey
json_data = { "registration_id": regid, "data" : {
"entry_id" : entry_id,
"email": email,
"date_modified": date_modified,
"kind": kind,
"reg_id": regid,
},
}
### Get regids
registration_data = {
"registration_ids": [regid],
}
headers = {'Content-Type': 'application/json', 'Authorization': myKey}
data = urllib.urlencode(json_data)
req = urllib2.Request(url, data)
req.add_header("Authorization", myKey)
f = urllib2.urlopen(req)
response = f.read()
f.close()
