Django基于客户端下载文件实现方法

import os
from django.http import HttpResponse
def file_download(request, file_path):
  # do something...
  with open(file_path) as f:
    c = f.read()
  return HttpResponse(c)

import os
from django.http import HttpResponse, Http404


def media_file_download(request, file_path):
  with open(file_path, 'rb') as f:
    try:
      response = HttpResponse(f)
      response['content_type'] = "application/octet-stream"
      response['Content-Disposition'] = 'attachment; filename=' + os.path.basename(file_path)
      return response
    except Exception:
      raise Http404

import os
from django.http import HttpResponse, Http404, StreamingHttpResponse

def stream_http_download(request, file_path):
  try:
    response = StreamingHttpResponse(open(file_path, 'rb'))
    response['content_type'] = "application/octet-stream"
    response['Content-Disposition'] = 'attachment; filename=' + os.path.basename(file_path)
    return response
  except Exception:
    raise Http404

import os
from django.http import HttpResponse, Http404, FileResponse
def file_response_download1(request, file_path):
  try:
    response = FileResponse(open(file_path, 'rb'))
    response['content_type'] = "application/octet-stream"
    response['Content-Disposition'] = 'attachment; filename=' + os.path.basename(file_path)
    return response
  except Exception:
    raise Http404
