Python中的Rest APIs获取身份验证令牌，然后将其设置为用于POST的变量

import requests

# 获取身份验证令牌
def get_access_token():
    token_url = "https://api.example.com/token"
    client_id = "your_client_id"
    client_secret = "your_client_secret"
    scope = "read write"  # 请求的范围

    # 使用OAuth 2.0进行身份验证
    response = requests.post(token_url, {
        "grant_type": "client_credentials",
        "client_id": client_id,
        "client_secret": client_secret,
        "scope": scope
    })

    # 检查响应状态码
    if response.status_code == 200:
        access_token = response.json()["access_token"]
        return access_token
    else:
        raise Exception("Failed to get access token")

# 设置身份验证令牌为POST变量
def set_token_for_post():
    post_url = "https://api.example.com/post"
    access_token = get_access_token()

    # 将访问令牌添加到请求的标头中
    headers = {
        "Authorization": "Bearer " + access_token,
        "Content-Type": "application/json"
    }

    # 发送POST请求
    response = requests.post(post_url, headers=headers, data={"key": "value"})

    # 处理响应
    if response.status_code == 200:
        print("POST request successful")
    else:
        print("POST request failed")

# 执行函数
set_token_for_post()
