Question

我们使用Django建立了一个前端网站来提供文件处理，但是如果有很多人（超过2个人）上载文件或下载文件，将导致系统错误。错误的原因很多，通常没有这样的文件，...等。请求和重新绑定存在问题。是有什么解决办法吗？

def download(request):
from django.http import FileResponse
file=open('kmeans/static/upload/example/example.zip','rb')
response =FileResponse(file)
response['Content-Type']='application/octet-stream'
response['Content-Disposition']='attachment;filename="example.zip"'
return response

def zip():
import zipfile
os.chdir(path)
with zipfile.ZipFile(current_time + '-kmeans.zip', 'w') as zf:
    zf.write('Cluster_result.xlsx')
    #zf.write('LDA_visual.html')
os.chdir(os_path)
     return True

 def handle_uploaded_file(file, filename):
    if not os.path.exists('kmeans/static/upload/'+ current_time + '/'):
    os.mkdir('kmeans/static/upload/'+ current_time + '/')
    global path
    path = 'kmeans/static/upload/'+ current_time + '/'

    with open(path + filename, 'wb+') as destination:
        for chunk in file.chunks():
            destination.write(chunk)
