Google Calendar API 不断返回 400 错误请求

Question

我的代码：

import os
import json

import dotenv
import requests
import requests_oauthlib


class Calendar():
    def __init__(self):
        dotenv.load_dotenv()

        self.api_key = os.getenv("API_KEY")
        self.calendar_id = os.getenv("CALENDAR_ID")
        self.access_token = os.getenv("GOOGLE_CALENDAR_API_ACCESS_TOKEN")

    def auth(self, scopes):
        with open("./assets/credentials.json", "r") as json_file:
            credentials = json.load(json_file)

            client_id = credentials["web"]["client_id"]
            client_secret = credentials["web"]["client_secret"]
            redirect_uri = credentials["web"]["redirect_uris"][0]
            authorization_url = credentials["web"]["auth_uri"]
            token_url = credentials["web"]["token_uri"]

        scopes = scopes

        with requests_oauthlib.OAuth2Session(client_id=client_id, scope=scopes, redirect_uri=redirect_uri) as session:
            authorization_url, state = session.authorization_url(authorization_url, access_type="offline", prompt="select_account")
            print("click the link to auth", authorization_url)

        redirect_response = input("Paste the redirect URL here:")
        credentials = session.fetch_token(token_url=token_url, client_secret=client_secret, authorization_response=redirect_response)

        dotenv.set_key(".env", key_to_set="GOOGLE_CALENDAR_API_ACCESS_TOKEN", value_to_set=credentials["access_token"], quote_mode="never")
        self.access_token = credentials["access_token"]

    def add_event(self, summary, start_date, end_date, description="", recurrence=False):
        url = f"https://www.googleapis.com/calendar/v3/calendars/{self.calendar_id}/events"

        headers = {
            "Authorization": f"Bearer {self.access_token}",
            "Accept": "application/json",
            "Content-Type": "application/json"
        }
       
        payload = {
            "end": {
                "dateTime": end_date,
                "timeZone": "Asia/Taipei"
            },
            "start": {
                "dateTime": start_date,
                "timeZone": "Asia/Taipei"
            }
        }

        if recurrence:
            payload["recurrence"] = ["RRULE:FREQ=WEEKLY"]

        response = requests.post(url=url, data=payload, headers=headers)

        return response.text


if __name__ == "__main__":
    c = Calendar()
    c.auth(["https://www.googleapis.com/auth/calendar", "https://www.googleapis.com/auth/calendar.events"])
    print(c.add_event(summary="test", start_date="2024-09-05T01:00:00.000", end_date="2024-09-17T13:00:00.000"))

输出：

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "badRequest",
    "message": "Bad Request"
   }
  ],
  "code": 400,
  "message": "Bad Request"
 }
}

我已经在 Google 的 API Explorer 上尝试了该 API，它成功地将事件添加到日历中。然而，当我在 python 中做同样的事情时，它出错了。

一开始，我以为是因为“datetime”格式，但我尝试了很多不同的格式，它们都返回相同的“400 bad request”。

我认为在Calendar API的“Events: insert”的情况下，请求正文需要是从JSON转换而来的字符串。那么，下面的修改怎么样？

来自：

response = requests.post(url=url, data=payload, headers=headers)

致：

response = requests.post(url=url, json=payload, headers=headers)

或

response = requests.post(url=url, data=json.dumps(payload), headers=headers)

注：

• 当我测试此修改中反映的脚本时，我确认可以创建事件而不会出现

  Bad Request

  的错误。
