python - 用于跟踪 Google Drive 上的更改的 Webhook

Question

我正在尝试创建 webhook 来跟踪 GDrive 上的一堆文件以获取以下信息：谁以及何时更改了文件。因此，使用本指南，我创建了侦听 webhook 并通过 NGROK 服务公开它的 python 服务器。

from flask import json
from flask import request
import requests
from flask import Flask, request, url_for, redirect, render_template

app = Flask(__name__)

@app.route('/')
def api_root():
    return "WEBHOOK"

@app.route('/*MyHtmlVerificationFile*')
def admin():
    return render_template('*MyHtmlVerificationFile*')

@app.route('/notif', methods=['POST'])
def api_gd_message():
    data = request.get_data()
    header = request.headers
    print(data)
    print(header)
    return ''

if __name__ == '__main__':
    app.run(debug=True)

然后，根据这个例子，我验证了 URL 域的所有权并注册了它，获得了凭证并编写了脚本来跟踪更改。

from oauth2client.service_account import ServiceAccountCredentials
from oauth2client.client import OAuth2Credentials
from pygdrive3 import service
import uuid
import requests
import json

channel_id = str(uuid.uuid4())
JSON_KEY_FILE = "creds.json"
SCOPES = ['https://www.googleapis.com/auth/drive.file',
         'https://www.googleapis.com/auth/drive.readonly',
         'https://www.googleapis.com/auth/drive']
credentials = ServiceAccountCredentials.from_json_keyfile_name(JSON_KEY_FILE, SCOPES)
access_token_info = credentials.get_access_token()

token = access_token_info.access_token

header = {
    'Authorization': f'Bearer ' + token,
    'Content-Type': 'application/json',
}

body = {
    "id": channel_id,
    "type": "web_hook",
    "address": "https://*MyDomain*/notif"
}

r = requests.post(url='https://www.googleapis.com/drive/v3/changes/watch?pageToken=101',
                  data=json.dumps(body), headers=header)

print(r.content)

结果是：

b'{\n 
"kind": "api#channel",\n 
"id": "MyId",\n 
"resourceId": "*MyResourceId*",\n 
"resourceUri": "*MyRsourceUri*",\n 
"expiration": "1612820606000"\n
}\n'

Process finished with exit code 0

并且 Webhook 启动时有服务器的消息。

问题是当我对 Gdrive 上的文件执行某些操作（编辑、删除、重命名等）时没有消息。
