如何通过 Python 中的 Dialogflow fulfillment 从 google 助手发送推送通知

Question

我正在 google Dialogflow 中开发聊天机器人以获得 google 帮助，我已经关注了这个 Documentation for showing Push notifications。我已请求许可，但现在我停留在该文档的最后一步 (Exchange the key for an access token and send a notification)。

谁能帮我做一下。我应该从我的 Python 履行代码发送哪个 JSON 响应？

Answer 1

试试这个：

import io
import json

import requests
from google.oauth2 import service_account
import google.auth.transport.requests

PATH_TO_SERVICE_ACCOUNT = 'path/to/json/service/account'

REQUIRED_SCOPE = 'https://www.googleapis.com/auth/actions.fulfillment.conversation'

# Get access token
with io.open(PATH_TO_SERVICE_ACCOUNT, 'r', encoding='utf-8') as json_fi:
    credentials_info = json.load(json_fi)
credentials = service_account.Credentials.from_service_account_info(
            credentials_info,  scopes=[REQUIRED_SCOPE])
request = google.auth.transport.requests.Request()
credentials.refresh(request)

headers = {
    'Authorization': 'Bearer: ' + credentials.token
}

payload = {'customPushMessage': {
    'userNotification': {
      'title': '<NOTIFICATION_TITLE>',
    },
    'target': {
      'userId': '<USER_ID>',
      'intent': '<INTENT>',
      # Expects a IETF BCP-47 language code (i.e. en-US)
      'locale': '<LOCALE>'
    },
  }
}

r = requests.get('https://actions.googleapis.com/v2/conversations:send', json=payload, headers=headers)

print(str(r.status_code) + ': ' + r.text)

终于，问题解决了。 @matthewayne 发布的代码有一些错误，例如请求必须是 "POST" 方法并且需要更改 payload 和 header 中的一些参数，因此它有效！，这里我更改了一些代码并尝试请求并收到通知！

我提到了this documentation to make it worked!

import io
import json

import requests
from google.oauth2 import service_account
import google.auth.transport.requests

PATH_TO_SERVICE_ACCOUNT = 'path/to/json/service/account'

REQUIRED_SCOPE = 'https://www.googleapis.com/auth/actions.fulfillment.conversation'

# Get access token
with io.open(PATH_TO_SERVICE_ACCOUNT, 'r', encoding='utf-8') as json_fi:
    credentials_info = json.load(json_fi)
credentials = service_account.Credentials.from_service_account_info(
    credentials_info, scopes=[REQUIRED_SCOPE])
request = google.auth.transport.requests.Request()
credentials.refresh(request)

headers = {
    'Authorization': 'Bearer ' + credentials.token
}

payload = {
    'customPushMessage': {
        'userNotification': {
            'title': 'Notification title',
            'text': 'Simple Text'
        },
        'target': {
            'userId': '<USER_ID>',
            'intent': '<INTENT>',
            # Expects a IETF BCP-47 language code (i.e. en-US)
            'locale': 'en-US'
        }
    }
}

r = requests.request("POST", 'https://actions.googleapis.com/v2/conversations:send', data=json.dumps(payload), headers=headers)

print(str(r.status_code) + ': ' + r.text)
