如何使用相同的端口运行python脚本 [英] How to run python script with the same port

问题描述

现在，我正在通过Gmail设置oauth2，以通过python脚本发送邮件.

Right now I am setting up oauth2 from Gmail to send mail from my python script.

我正在使用Google的快速入门代码来验证授权代码，但是我遇到的情况是，当我运行python脚本时，端口总是在变化.

I am using a quick start code from Google to verify the authorize code but I am facing a situation where the port always changes when I am running the python script.

from __future__ import print_function
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

# If modifying these scopes, delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/gmail.readonly']

def main():
    """Shows basic usage of the Gmail API.
    Lists the user's Gmail labels.
    """
    creds = None
    # The file token.pickle stores the user's access and refresh tokens, and is
    # created automatically when the authorization flow completes for the first
    # time.
    if os.path.exists('token.pickle'):
        with open('token.pickle', 'rb') as token:
            creds = pickle.load(token)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                '../credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.pickle', 'wb') as token:
            pickle.dump(creds, token)

    service = build('gmail', 'v1', credentials=creds)

    # Call the Gmail API
    results = service.users().labels().list(userId='me').execute()
    labels = results.get('labels', [])

    if not labels:
        print('No labels found.')
    else:
        print('Labels:')
        for label in labels:
            print(label['name'])

if __name__ == '__main__':
    main()

此代码的问题是，每当我运行脚本时，它总是会更改端口，并且无法在Google控制台中设置重定向的URI.

My problem with this code is that whenever I run the script, it always changes the port and I cannot set the redirected URI in google console.

我的问题是如何在python脚本上设置运行端口?

My question is that how can I set the running port on python script?

推荐答案

例如，如何进行以下修改?

For example, how about the following modification?

creds = flow.run_local_server(port=0)

收件人:

creds = flow.run_local_server()

• 在这种情况下，每次使用端口 8080 .

或

creds = flow.run_local_server(port=8000)

• 在这种情况下，每次使用端口 8000 .
• run_local_server
