Question

我正在使用此视图功能来提供下载文件，

from django.http import FileResponse
def sendFiles(request): 
    filename = request.GET['filename']
    pathToFile = os.path.join(filesDir, filename)
    response = FileResponse(open(pathToFile, 'rb'))

    response['Content-Type'] = 'application/octet-stream'
    response[
        'Content-Disposition'] = 'attachment; filename="{}"'.format(filename)
    response['Content-Length'] = os.path.getsize(pathToFile)
    # HttpResponse(open(os.path.join(os.getcwd(), 'LYYDownloaderServer.log'), 'r'), content_type='text/plain')
    return response

将http://127.0.0.1:8000/VideoParser/files/?filename=Git-2.8.4-32-bit.exe粘贴到浏览器地址栏并输入后，然后文件开始下载，当我暂停下载，然后服务器控制台输出以下异常，任何人都可以在这里弄清楚什么是错的？使用Python 3.5.1和Django 1.9在Win10上测试
