Question

当我尝试通过GCM发送消息时，我总是得到一个空的json响应{}。

我正在使用python-gcm，这是我的代码：

from gcm import GCM

API_KEY = "AldaSyAwnh5jAAAAAAABvBTyqDdMITCoEE8GLZ"
my_gcm = GCM(api_key=API_KEY)
data = {'param1': 'value1', 'param2': 'value2'}


# JSON request
#reg_ids = ['12', '34', '69']
reg_ids = ['ALA91bE9QSkVKcmAAAAAAda8UsNs27R-29pJHDqwIiwqxSAStmhpFo2hKD0SipoCjgANvFJ7trdQZuJCjMaUAAAA6zmETYDncD9YTiVZ61eG1pwXdOJC7mozlt76OoyM81OasWi9_ibGklNfhWGhJpg']
response = my_gcm.json_request(registration_ids=reg_ids, data=data)

# Handling errors
if 'errors' in response:
    for error, reg_ids in response['errors'].items():
        # Check for errors and act accordingly
        if error is 'NotRegistered':
            # Remove reg_ids from database
            for reg_id in reg_ids:
                entity.filter(registration_id=reg_id).delete()

if 'canonical' in response:
    for reg_id, canonical_id in response['canonical'].items():
        # Repace reg_id with canonical_id in your database
        entry = entity.filter(registration_id=reg_id)
        entry.registration_id = canonical_id
        entry.save()

我做错了什么，我应该尝试另一种选择吗？另一个细节：

我正在使用烧瓶。
在我的开发者谷歌控制台中，我有谷歌地图

看起来不是直接使用python-gcm。然后，根据：

请记住标志dry_run=True用于测试。以下代码就像魅力一样：）

from flask import Flask
app = Flask(__name__)

from flask.ext.gcm import GCM
API_KEY = "AldaSyAwnh5jAAAAAAABvBTyqDdMITCoEE8GLZ"
gcm = GCM()
app.config['GCM_KEY'] = API_KEY
gcm.init_app(app)

data = {'param1': 'value1', 'param2': 'value2'}

multicast = JSONMessage(["ALA91bE9QSkVKcmAAAAAAda8UsNs27R-29pJHDqwIiwqxSAStmhpFo2hKD0SipoCjgANvFJ7trdQZuJCjMaUAAAA6zmETYDncD9YTiVZ61eG1pwXdOJC7mozlt76OoyM81OasWi9_ibGklNfhWGhJpg"], data, collapse_key='my.key', dry_run=False)

try:
    # attempt send
    res_multicast = gcm.send(multicast)

for res in [res_multicast]:
    # nothing to do on success
    for reg_id, msg_id in res.success.items():
        print "Successfully sent %s as %s" % (reg_id, msg_id)

    # update your registration ID's
    for reg_id, new_reg_id in res.canonical.items():
        print "Replacing %s with %s in database" % (reg_id, new_reg_id)

    # probably app was uninstalled
    for reg_id in res.not_registered:
        print "Removing %s from database" % reg_id

    # unrecoverably failed, these ID's will not be retried
    # consult GCM manual for all error codes
    for reg_id, err_code in res.failed.items():
        print "Removing %s because %s" % (reg_id, err_code)

    # if some registration ID's have recoverably failed
    if res.needs_retry():
        # construct new message with only failed regids
        retry_msg = res.retry()
        # you have to wait before attemting again. delay()
        # will tell you how long to wait depending on your
        # current retry counter, starting from 0.
        print "Wait or schedule task after %s seconds" % res.delay(retry)
        # retry += 1 and send retry_msg again

except GCMAuthenticationError:
    # stop and fix your settings
    print "Your Google API key is rejected"
except ValueError, e:
    # probably your extra options, such as time_to_live,
    # are invalid. Read error message for more info.
    print "Invalid message/option or invalid GCM response"
    print e.args[0]
except Exception:
    # your network is down or maybe proxy settings
    # are broken. when problem is resolved, you can
    # retry the whole message.
    print "Something wrong with requests library"

使用python-gcm清空json响应
