在Django中批准付款后从Paypal脚本提交表单

# forms.py
from django import forms

class PaymentForm(forms.Form):
    amount = forms.DecimalField()
    description = forms.CharField()

# views.py
from django.shortcuts import render
from paypal import PayPalClient

def process_payment(request):
    if request.method == 'POST':
        form = PaymentForm(request.POST)
        if form.is_valid():
            amount = form.cleaned_data['amount']
            description = form.cleaned_data['description']
            
            # 调用Paypal的API进行付款操作
            paypal_client = PayPalClient()
            payment_result = paypal_client.process_payment(amount, description)
            
            if payment_result.success:
                # 付款成功，进行相应的处理
                # 更新数据库，发送邮件等
                return render(request, 'payment_success.html')
            else:
                # 付款失败，返回错误信息给用户
                error_message = payment_result.error_message
                return render(request, 'payment_error.html', {'error_message': error_message})
    else:
        form = PaymentForm()
    
    return render(request, 'payment_form.html', {'form': form})
