在线云评测系统的登陆与注册界面的实现

django 框架中 url.py 的python代码，主要表面页面访问的路径，红色的代码是与登陆注册的路径相关的配置

页面的访问类似于“judgeOL/register”,“judgeOL/login”的路径。

from django.conf.urls import urlfrom . import viewsapp_name = 'judgeOL'urlpatterns = [    # ex: /judgeOL/    url(r'^login/$', views.LoginView.as_view(), name='login'),    url(r'^login_method/$', views.login, name='login_method'),    url(r'^register_method/$', views.register, name='register_method'),    url(r'^register/$', views.RegisterView.as_view(), name='register'),    url(r'^problems/$', views.ProblemsView.as_view(), name='problems'),    url(r'^(?P<problem_id>[0-9]+)/coding/$', views.CodingView.as_view(), name='coding'),    url(r'^discussions/$', views.DiscussionView.as_view(), name='discussions'),    url(r'^responses/$', views.ResponseView.as_view(), name='responses'),    url(r'^edit/$', views.editView.as_view(), name='edit'),    ]

django 框架中 view.py 的python代码,实现了登陆与注册的处理逻辑，还未实现cookie 或者 session,暂时先处理到这里。

def login(request):    if request.method == 'GET':        userform = LoginForm()        return render_to_response('judgeOL/login.html',RequestContext(request))    else:        userform = LoginForm(request.POST)        if userform.is_valid():            email = userform.cleaned_data['email']            password = userform.cleaned_data['password']            success = User.objects.filter(mail=email,password=password)            if success:                """response.set_cookie('email',email,3600)                return HttpResponseRedirect('judgeOL:problems',RequestContext(request))"""                return HttpResponseRedirect(reverse('judgeOL:problems'))            else:                return HttpResponseRedirect(reverse('judgeOL:login'))def register(request):    if request.method == 'GET':        userform = RegisterForm()        return HttpResponseRedirect(reverse('judgeOL:register'))    else:        userform = RegisterForm(request.POST)        if userform.is_valid():            email = userform.cleaned_data['email']            username = userform.cleaned_data['username']            password = userform.cleaned_data['password']            check_email = User.objects.filter(mail = email)            check_username = User.objects.filter(name = username)            if check_email and check_username:                return HttpResponseRedirect(reverse('judgeOL:register'))            else:                User.objects.create(name=username, password=password, mail=email)                return HttpResponseRedirect(reverse('judgeOL:login'))

bootstrap 写的登陆与注册界面，简洁高效，因为用户管理不是重点，这几个方面都尽量实现尽可能少的功能，后期可以逐步添加。

html 页面 form 表单的提交：

登陆界面html:

<div class="well form-sign-in-well" ><form class="form-signin" action="{% url 'judgeOL:login_method' %}" method="post">{% csrf_token %}<br/><h2 class="form-signin-heading">Please sign in</h2><br/><label for="inputEmail" class="sr-only">Email address</label><input type="email" name="email" id="inputEmail" class="form-control" placeholder="Email address" required autofocus><br/><label for="inputPassword" class="sr-only">Password</label><input type="password" name="password" id="inputPassword" class="form-control" placeholder="Password" required><br/><button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button></form></div>

注册界面html:

    <div class="well form-sign-up-well" >        <form class="form-signin" action="{% url 'judgeOL:register_method' %}" method="post">            {% csrf_token %}            <br/>            <h2 class="form-signin-heading">Please sign up</h2>            <br/>            <label for="inputName" class="sr-only">User Name</label>            <input type="name" name="username" id="inputName" class="form-control" placeholder="User Name" required autofocus>            <br/>            <label for="inputEmail" class="sr-only">Email address</label>            <input type="email" name="email" id="inputEmail" class="form-control" placeholder="Email address" required>            <br/>            <label for="inputPassword" class="sr-only">Password</label>            <input type="password" name="password"id="inputPassword" class="form-control" placeholder="Password" required>            <br/>            <button class="btn btn-lg btn-primary btn-block" type="submit">Sign up</button>        </form>    </div>
