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/")

刚开始学，里面做了一个login.html，

点击提交之后，文件没有上传，也没有反应，是什么原因啊？

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
</head>
<body>
<from action="/login/" method="POST" enctype="multipart/form-data">
<p>
男：<input type="radio" name="gender" value="1"/>
女：<input type="radio" name="gender" value="2"/>
</p>
<p>
男：<input type="checkbox" name="favor" value="11"/>
女：<input type="checkbox" name="favor" value="22"/>
</p>
<p>
<input type="file" name="fff"/>
</p>
<input type="submit" value="提交"/>
</from>
</body>
</html>
