使用 ReportLab 生成 PDF
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas
from reportlab.lib.units import inch
def create_invoice(data: dict, output_path: str):
c = canvas.Canvas(output_path, pagesize=letter)
width, height = letter
# 页眉
c.setFont("Helvetica-Bold", 24)
c.drawString(1*inch, height - 1*inch, "INVOICE")
# 发票详情
c.setFont("Helvetica", 12)
c.drawString(1*inch, height - 1.5*inch, f"Invoice #: {data['invoice_number']}")
c.drawString(1*inch, height - 1.75*inch, f"Date: {data['date']}")
# 发件人/收件人
y = height - 2.5*inch
c.drawString(1*inch, y, f"From: {data['from']['name']}")
c.drawString(4*inch, y, f"To: {data['to']['name']}")
# 项目表格
y = height - 4*inch
c.setFont("Helvetica-Bold", 10)
c.drawString(1*inch, y, "Description")
c.drawString(4*inch, y, "Qty")
c.drawString(5*inch, y, "Rate")
c.drawString(6*inch, y, "Amount")
c.setFont("Helvetica", 10)
subtotal = 0
for item in data['items']:
y -= 0.3*inch
amount = item['quantity'] * item['rate']
subtotal += amount
c.drawString(1*inch, y, item['description'])
c.drawString(4*inch, y, str(item['quantity']))
c.drawString(5*inch, y, f"${item['rate']:.2f}")
c.drawString(6*inch, y, f"${amount:.2f}")
# 总计
tax = subtotal * data['tax_rate']
total = subtotal + tax
y -= 0.5*inch
c.drawString(5*inch, y, f"Subtotal: ${subtotal:.2f}")
y -= 0.25*inch
c.drawString(5*inch, y, f"Tax ({data['tax_rate']*100}%): ${tax:.2f}")
y -= 0.25*inch
c.setFont("Helvetica-Bold", 12)
c.drawString(5*inch, y, f"Total: ${total:.2f}")
c.save()
return output_path
