沙箱账号链接 沙箱账号链接

---

1. 创建沙箱应用

2. 记录 Client ID和 Secret 后面有用 然后点击进去创建回调url和回调事件，可以全选事件也可以选择你需要的

3.拿沙箱账号信息去登录

4.登录后创建订阅产品内容。记住产品id

5.配置django后端信息和创建订阅链接进行支付

python">import requests
from datetime import datetime# 配置 PayPal 凭据和环境
PAYPAL_CLIENT_ID_SANDBOX = '沙箱SANDBOX'
PAYPAL_SECRET_KEY_SANDBOX = '沙箱密钥'
PAYPAL_CLIENT_ID_PRODUCTION = ''  # 替换为实际生产环境的客户端 ID
PAYPAL_SECRET_KEY_PRODUCTION = ''  # 替换为实际生产环境的密钥
PAYPAL_MODE = 'sandbox'  # 'sandbox' 或 'live'
PAYPAL_BASE_URL = "https://api.sandbox.paypal.com" if PAYPAL_MODE == "sandbox" else "https://api.paypal.com"# 工具函数：生成自定义订单号
def generate_order_id():"""根据当前时间生成唯一订单号格式：P-YYYYMMDD-HHMMSS"""current_time = datetime.now().strftime("%Y%m%d-%H%M%S")return f"P-{current_time}"# 工具函数：获取 PayPal 访问令牌
def get_paypal_access_token():"""获取 PayPal API 访问令牌"""url = f"{PAYPAL_BASE_URL}/v1/oauth2/token"auth = (PAYPAL_CLIENT_ID_SANDBOX, PAYPAL_SECRET_KEY_SANDBOX)headers = {"Accept": "application/json", "Accept-Language": "en_US"}data = {"grant_type": "client_credentials"}response = requests.post(url, headers=headers, data=data, auth=auth)if response.status_code == 200:return response.json().get("access_token")else:raise Exception(f"获取访问令牌失败: {response.text}")# 创建 PayPal 订阅链接
def create_paypal_subscription_link(plan_id):"""使用 PayPal API 创建订阅链接:param plan_id: 示例计划 ID (如: P-4KL07437GC7241026M5AW2JY):return: 订阅链接 URL"""try:# 获取访问令牌access_token = get_paypal_access_token()# PayPal 订阅 API URLsubscription_url = f"{PAYPAL_BASE_URL}/v1/billing/subscriptions"# 自定义订单号custom_order_id = generate_order_id()# 构建订阅请求的 payloadpayload = {"plan_id": plan_id,"custom_id": custom_order_id,"application_context": {"brand_name": "Your Brand Name","user_action": "SUBSCRIBE_NOW","landing_page": "BILLING","return_url": f"支付成功跳转的url","cancel_url": f"取消支付跳转的url",}}headers = {"Authorization": f"Bearer {access_token}","Content-Type": "application/json"}# 发送请求以创建订阅response = requests.post(subscription_url, json=payload, headers=headers)if response.status_code in [200, 201]:# 提取审批链接subscription_data = response.json()approval_url = next(link["href"] for link in subscription_data["links"] if link["rel"] == "approve")print(f"订阅链接生成成功: {approval_url}")return approval_urlelse:print(f"创建订阅链接失败: {response.text}")return Noneexcept Exception as e:print(f"创建订阅链接时发生错误: {e}")return None# 示例调用

6.订阅成功后回调

当用户进入approval_url 付款成功后会回调到给个前面创建的回调链接。测试付款的账号也在开发者后台生成自行付款测试。最后后端再根据不同的回调类型操作数据库即可

python">def paypal_webhook(request):"""PayPal Webhook 回调入口"""try:# 解析请求体webhook_data = json.loads(request.body.decode("utf-8"))print("[Webhook] 收到数据:", json.dumps(webhook_data, indent=4))event_type = webhook_data.get("event_type")resource = webhook_data.get("resource")webhook_id = webhook_data.get("id")print(f"[Webhook] 事件类型: {event_type}, Webhook ID: {webhook_id}")handle_webhook_event(event_type, resource, webhook_id)except Exception as e:print(f"[Webhook] 错误: {str(e)}")return JsonResponse({"code": 500, "message": f"服务器错误: {str(e)}"})def handle_webhook_event(event_type, resource, webhook_id):"""处理 PayPal Webhook 回调事件:param event_type: 回调事件类型（如 BILLLING.SUBSCRIPTION.ACTIVATED）:param resource: 事件的资源数据（JSON 格式）:param webhook_id: PayPal Webhook ID，用于验证请求合法性"""print(f"[Webhook 回调] 收到事件: {event_type}, Webhook ID: {webhook_id}")if event_type == "BILLING.SUBSCRIPTION.ACTIVATED":# 处理订阅激活事件print("[Webhook 回调] 事件类型: 订阅已激活")print(f"[Webhook 回调] 资源数据: {resource}")handle_subscription_activated(resource, webhook_id)elif event_type == "BILLING.SUBSCRIPTION.UPDATED":# 处理订阅更新事件print("[Webhook 回调] 事件类型: 订阅已更新")print(f"[Webhook 回调] 资源数据: {resource}")handle_subscription_updated(resource, webhook_id)elif event_type == "BILLING.SUBSCRIPTION.CANCELLED":# 处理订阅取消事件print("[Webhook 回调] 事件类型: 订阅已取消")print(f"[Webhook 回调] 资源数据: {resource}")handle_subscription_cancelled(resource, webhook_id)elif event_type == "PAYMENT.SALE.COMPLETED":# 处理付款完成事件print("[Webhook 回调] 事件类型: 付款已完成")print(f"[Webhook 回调] 资源数据: {resource}")handle_payment_completed(resource, webhook_id)else:# 未知的事件类型print(f"[Webhook 回调] 未知事件类型: {event_type}")print(f"[Webhook 回调] 资源数据: {resource}")

7.最后为了安全性建议在生产环境对回调进行验签再操作。有其它疑问可以互相交流
