### Midtrans支付流程演示 为了展示Midtrans支付网关集成的过程，下面提供了一个简单的Python示例来初始化交易并重定向客户到付款页面。此过程涉及创建一个具有必要细节的有效负载并向Midtrans服务器发送请求以获取重定向URL。 ```python import requests import json def initiate_midtrans_payment(order_id, gross_amount, customer_details): server_key = 'YOUR_SERVER_KEY' # 替换为实际的Server Key url = "https://api.sandbox.midtrans.com/v2/charge" payload = { "payment_type": "redirect", "transaction_details": { "order_id": order_id, "gross_amount": gross_amount }, "customer_details": customer_details, "credit_card": { "secure": True } } headers = { "Content-Type": "application/json", "Accept": "application/json", "Authorization": f"Basic {server_key}" } response = requests.post(url, data=json.dumps(payload), headers=headers) if response.status_code == 201: redirect_url = response.json().get('redirect_url') print(f'Redirect to: {redirect_url}') return redirect_url else: raise Exception("Failed to create transaction", response.text) initiate_midtrans_payment( order_id="ORD-BIG-001", gross_amount=200_000, customer_details={ "first_name": "John", "last_name": "Doe", "email": "johndoe@example.com", "phone": "+628123456789" } ) ``` 上述代码展示了如何通过POST方法向Midtrans API提交一个新的支付请求[^1]。一旦成功处理了这个API调用，就会返回一个`redirect_url`字段给商户应用；之后应该把用户浏览器重定向至该链接完成后续操作[^2]。
