在django中显示pdf文件

Posted 2021-05-06

嗨，我是django框架的新手当用户点击我需要显示我正在使用的代码的pdf文件

with open(file_path+file_name, 'rb') as pdf:
    response = HttpResponse(pdf.read(), mimetype='application/pdf', contenttype='application/pdf')
    response['Content-Disposition'] = 'inline;filename=some_file.pdf'

我得到的错误是

File "/usr/local/lib/python3.4/dist-packages/rest_framework/viewsets.py", line 90, in view
    return self.dispatch(request, *args, **kwargs)
  File "/usr/local/lib/python3.4/dist-packages/rest_framework/views.py", line 489, in dispatch
    response = self.handle_exception(exc)
  File "/usr/local/lib/python3.4/dist-packages/rest_framework/views.py", line 449, in handle_exception
    self.raise_uncaught_exception(exc)
  File "/usr/local/lib/python3.4/dist-packages/rest_framework/views.py", line 486, in dispatch
    response = handler(request, *args, **kwargs)
  File "/home/tritwdapp/tribalwelfare/inspection/inspectdataview.py", line 290, in getSubmitReport
    response = HttpResponse(pdf.read(), mimetype='application/pdf',contenttype='application/pdf')
  File "/usr/local/lib/python3.4/dist-packages/django/http/response.py", line 283, in __init__
    super(HttpResponse, self).__init__(*args, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'contenttype'

谁能帮帮我吗

答案

试试这个：

def pdf_view(request):
    with open('file.pdf', 'r') as pdf:
        response = HttpResponse(pdf.read(), content_type='application/pdf')
        response['Content-Disposition'] = 'inline;filename=some_file.pdf'
        return response

mimetype已被content_type取代。它被删除在Django 1.7。另外，你拼错了。请注意，这样的解决方案并非最佳。通常，出于性能原因，您的Web服务器将提供这些文件。
