drf+vue实现文件下载

 

后端代码：

   re_path(r'^package/download/(?P<file_path>.*)/$', views.PackageDownload.as_view({'post': 'file_download'}))

from django.http import Http404, FileResponse

class PackageDownload(viewsets.ModelViewSet):
    permission_classes = [IsAuthenticated]

    def file_download(self, request, file_path):
        ext = os.path.basename(file_path).split('.')[-1].lower()
        # cannot be used to download py, db and sqlite3 files.
        if ext not in ['py', 'db', 'sqlite3']:
            response_file = FileResponse(open(file_path, 'rb'))
            response_file['content_type'] = "application/octet-stream"
            response_file['Content-Disposition'] = 'attachment; filename=' + os.path.basename(file_path)
            return response_file
        else:
            raise restful.params_error("不允许的请求")

这里要判断一下文件类型，保证安全。
