python - Bottle框架生成pdf

Question

我需要使用 Bottle 框架生成 PDF 文档。

我尝试了类似于 Django 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

Answer 1

Bottle 函数不应该返回 response 对象，它们应该返回一个可迭代对象(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()
