Django实现文件上传和下载功能

def upload(request):
 if request.method == "POST": # 请求方法为POST时，进行处理
 myFile = request.FILES.get("myfile", None) # 获取上传的文件，如果没有文件，则默认为None
 if not myFile:
 return HttpResponse("no files for upload!")
 # destination=open(os.path.join('upload',myFile.name),'wb+')
 destination = open(
 os.path.join("你的文件存放地址", myFile.name),
 'wb+') # 打开特定的文件进行二进制的写操作
 for chunk in myFile.chunks(): # 分块写入文件
 destination.write(chunk)
 destination.close()
 return HttpResponse("upload over!")
 else:
 file_list = []
 files = os.listdir('D:\python\Salary management system\django\managementsystem\\file')
 for i in files:
 file_list.append(i)
 return render(request, 'upload.html', {'file_list': file_list})
