收到“错误请求”错误，HTTP 错误代码为 400

Question

我尝试通过 Google Calendar API 执行自动化任务并收到以下错误消息：

C:\Users\Documents\Calendar Add-On>python calendar_v2.py
Traceback (most recent call last):
  File "C:\Users\Documents\Calendar Add-On\calendar_v2.py", line 68, in <module>
    create_events(calendar_id)
  File "C:\Users\Documents\Calendar Add-On\calendar_v2.py", line 46, in create_events
    events_result = service.events().list(
  File "C:\Users\anaconda3\lib\site-packages\googleapiclient\_helpers.py", line 130, in positional_wrapper
    return wrapped(*args, **kwargs)
  File "C:\Users\anaconda3\lib\site-packages\googleapiclient\http.py", line 938, in execute
    raise HttpError(resp, content, uri=self.uri)
googleapiclient.errors.HttpError: <HttpError 400 when requesting https://www.googleapis.com/calendar/v3/calendars/primary/events?timeMin=2024-05-15T20%3A43%3A15.671352&timeMax=2024-06-14T20%3A43%3A15.671352&singleEvents=true&alt=json returned "Bad Request". Details: "[{'domain': 'global', 'reason': 'badRequest', 'message': 'Bad Request'}]">

我似乎不明白为什么它给我这个错误消息。

我已经尝试了很多次代码，但总是回到这个问题。我的代码的简短片段（我显然省略了日历 ID 和 .json 文件名）：

from google.oauth2 import service_account
from googleapiclient.discovery import build
from datetime import datetime, timedelta

# Define the service account credentials
SERVICE_ACCOUNT_FILE = r'path_to_service_account_file.json'
SCOPES = ['https://www.googleapis.com/auth/calendar']

# Authenticate and build the Calendar API client
credentials = service_account.Credentials.from_service_account_file(
    SERVICE_ACCOUNT_FILE, scopes=SCOPES)
service = build('calendar', 'v3', credentials=credentials)

# Function to add buffer before and after each event
def add_event_buffer(event):
    start_time = event['start'].get('dateTime')
    end_time = event['end'].get('dateTime')
    
    if start_time and end_time:
        start_dt = datetime.fromisoformat(start_time)
        end_dt = datetime.fromisoformat(end_time)
        buffer_time = timedelta(minutes=10)
        buffered_start_time = (start_dt - buffer_time).strftime('%Y-%m-%dT%H:%M:%S.%fZ')
        buffered_end_time = (end_dt + buffer_time).strftime('%Y-%m-%dT%H:%M:%S.%fZ')
        event['start']['dateTime'] = buffered_start_time
        event['end']['dateTime'] = buffered_end_time
        event['summary'] = 'Travel Time - ' + event['summary']
        
    return event

# Function to create buffered events on the calendar
def create_buffered_events(calendar_id):
    try:
        start_time = datetime.now().isoformat()
        end_time = (datetime.now() + timedelta(days=30)).isoformat()
        events_result = service.events().list(
            calendarId=calendar_id,
            timeMin=start_time,
            timeMax=end_time,
            singleEvents=True
        ).execute()
        
        events = events_result.get('items', [])
        if not events:
            print('No events found.')
        else:
            for event in events:
                if 'Travel Time' in event.get('summary', ''):
                    print(f'Skipping buffered event for: {event["summary"]} (already buffered)')
                    continue
                buffered_event = add_event_buffer(event)
                if 'id' in event:
                    service.events().update(calendarId=calendar_id, eventId=event['id'], body=buffered_event).execute()
                    print(f'Buffered event updated for: {buffered_event["summary"]}')
                else:
                    service.events().insert(calendarId=calendar_id, body=buffered_event).execute()
                    print(f'Buffered event created for: {buffered_event["summary"]}')
    except Exception as e:
        print("An error occurred:", e)
        raise

在你的脚本中，进行以下修改怎么样？请修改

create_buffered_events

如下。

来自：

start_time = datetime.now().isoformat()
end_time = (datetime.now() + timedelta(days=30)).isoformat()

致：

start_time = datetime.now().isoformat() + "Z"
end_time = (datetime.now() + timedelta(days=30)).isoformat() + "Z"

• 当我测试你的脚本时，我确认了同样的错误消息。并且，当我测试脚本反映上述修改时，没有发生错误，并且事件已更新。
