在Python中获取访问令牌，就像Postman中一样

import requests

client_id = "YOUR_CLIENT_ID"
client_secret = "YOUR_CLIENT_SECRET"
redirect_uri = "YOUR_REDIRECT_URI"
authorization_url = "https://example.com/oauth/authorize"

# 构建授权请求的URL
auth_params = {
    "client_id": client_id,
    "redirect_uri": redirect_uri,
    "response_type": "code",
    "scope": "YOUR_SCOPES"
}
auth_url = requests.Request('GET', authorization_url, params=auth_params).prepare().url

# 在浏览器中打开授权请求的URL，用户将被要求登录并授权应用访问其资源

token_url = "https://example.com/oauth/token"

# 构建获取访问令牌的请求
token_params = {
    "grant_type": "authorization_code",
    "code": "YOUR_AUTHORIZATION_CODE",
    "client_id": client_id,
    "client_secret": client_secret,
    "redirect_uri": redirect_uri
}
response = requests.post(token_url, data=token_params)

# 解析响应获取访问令牌
access_token = response.json()["access_token"]

api_url = "https://example.com/api/endpoint"

# 构建API请求并添加访问令牌
headers = {
    "Authorization": f"Bearer {access_token}"
}
response = requests.get(api_url, headers=headers)

# 处理API响应
