创建了django项目之后，创建app。

配置urls：

from django.conf.urls import url
from django.contrib import admin
from myapp01 import views
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^login/', views.login),
]

配置views(app01.views)：

from django.shortcuts import render
from django import forms
# Create your views here.
class InputForm(forms.Form):
    # 下面使用的变量名必须和html中input标签的name值相同
    username = forms.CharField(required=True)
    password = forms.CharField(required=True)
def login(request):
    if request.method == 'POST':
        obj = InputForm(request.POST)
        ret = obj.is_valid()
        print(ret,obj.data)
        if ret:
            print(obj.clean())
        else:
            print(obj.errors)
    return render(request, 'login.html')

配置tamplates（index.html）：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <div>
        <div>
            <input type="text" name="username" />
        </div>
        <div>
            <input type="password" name="password" />
        </div>
        <input type="button" value="提交" onclick="DoSubmit();"/>
    </div>
    <script src="/static/jquery-2.1.4.min.js"></script>
    <script>
        function DoSubmit() {
            var input_dic = {};
            $('input').each(function () {
                var v = $(this).val();
                var n = $(this).attr('name');
                input_dic[n] = v;
            });
            console.log(input_dic);
            $.ajax({
                url:'/login/',
                type:'POST',
                data:input_dic,
                success: function (rdata) {
                    console.log(rdata);
                },
                error: function () {
                    
                }
            })
        }
    </script>
</body>
</html>
