Xero : OAuth2: Python3:获取刷新令牌的示例代码

from requests_oauthlib import OAuth2Session

# 定义Xero OAuth2的授权和回调URL
authorization_base_url = 'https://login.xero.com/identity/connect/authorize'
token_url = 'https://identity.xero.com/connect/token'
redirect_uri = 'http://localhost:8000/callback'

# 定义Xero应用程序的客户端ID和客户端密钥
client_id = 'your_client_id'
client_secret = 'your_client_secret'

# 创建OAuth2会话
xero = OAuth2Session(client_id, redirect_uri=redirect_uri)

# 生成授权URL
authorization_url, state = xero.authorization_url(authorization_base_url)

# 打印授权URL，用户需要点击此URL进行授权
print('请访问以下URL进行授权：')
print(authorization_url)

# 获取回调URL中的授权码
authorization_code = input('请输入回调URL中的授权码：')

# 使用授权码获取访问令牌和刷新令牌
token = xero.fetch_token(token_url, code=authorization_code, client_secret=client_secret)

# 打印刷新令牌
print('刷新令牌：', token['refresh_token'])
