编写你的视图¶
FileResponse
下面是一个“你好世界”的例子:
import io
from django.http import FileResponse
from reportlab.pdfgen import canvas
def some_view(request):
# Create a file-like buffer to receive PDF data.
buffer = io.BytesIO()
# Create the PDF object, using the buffer as its "file."
p = canvas.Canvas(buffer)
# Draw things on the PDF. Here's where the PDF generation happens.
# See the ReportLab documentation for the full list of functionality.
p.drawString(100, 100, "Hello world.")
# Close the PDF object cleanly, and we're done.
p.showPage()
p.save()
# FileResponse sets the Content-Disposition header so that browsers
# present the option to save the file.
buffer.seek(0)
return FileResponse(buffer, as_attachment=True, filename='hello.pdf')
代码和注释应该是不言自明的,但有几点值得一提:

备注
ReportLab不是线程安全的。我们的一些用户报告了构建生成django视图的PDF时出现的一些奇怪问题,这些视图可同时被许多人访问。
