submit点击之后没有反应，是什么原因，萌新刚开始学

from django.shortcuts import HttpResponse

from django.shortcuts import render

from django.shortcuts import redirect

# Create your views here.

def index(request):
    return HttpResponse("index")

def login(request):
    print("@@@@@@@@@@@@@@@@@")
    if request.method == "GET":
        print("******************")
        return render(request,"login.html")
        # return redirect(request, "/index/")
    elif request.method == "POST":
        v = request.POST.get("gender")
        f = request.POST.getlist("favor")

        print(v)
        print(f)

        import os
        obj = request.FILES.get("fff")
        file_path = os.path.join("upload",obj.name)
        f = open(file_path,mode="wb")
        for i in obj.chunks():
            f.write(i)
        f.close()

        return render(request,"login.html")
        # return redirect(request, "/index/")
    else:
        return redirect(request,"/index/")

点击提交之后，文件没有上传，也没有反应，是什么原因啊？
