Python 瓶子框架生成pdf

我需要使用

瓶子

框架生成PDF文档

我尝试了与Django类似的方法，但没有成功：

@bottle.route('/pd')
def create_pdf():
    response.headers['Content-Type'] = 'application/pdf; charset=UTF-8'
    response.headers['Content-Disposition'] = 'attachment; filename="test.pdf"'
    from io import BytesIO
    buffer = BytesIO()
    from reportlab.pdfgen import canvas
    p = canvas.Canvas(buffer)
    p.drawString(100,100,'Hello World')
    p.showPage()
    p.save()
    pdf = buffer.getvalue()
    buffer.close()
    response.write(pdf)
    return response

---

瓶子函数不应该返回

响应

对象，它们应该返回一个iterable（字符串、列表、生成器等）

所以你想要这个：

from io import BytesIO
from reportlab.pdfgen import canvas

@bottle.route('/pd')
def create_pdf():
    response.headers['Content-Type'] = 'application/pdf; charset=UTF-8'
    response.headers['Content-Disposition'] = 'attachment; filename="test.pdf"'

    buffer = BytesIO()
    p = canvas.Canvas(buffer)
    p.drawString(100,100,'Hello World')
    p.showPage()
    p.save()

    return buffer.getvalue()
