1、models

if user:
back_message['user'] = name
return JsonResponse(back_message) 后面类推
else:
return HttpResponse('用户名或密码错误')
else:

return render(request,'login.html')
def get_random_color():

4、urls
from django.conf.urls import url
from django.contrib import admin
from mybbs import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^login/', views.login),
url(r'^get_code/', views.get_code),
]
5、login.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="/static/bootstrap-3.3.7-dist/css/bootstrap.min.css">
<script src="/static/jquery-3.3.1.js"></script>

</div>
<script>
$("#submit").click(function () {
$.ajax({
url: '/login/',
type: 'post',
data: {
'name': $("#id_name").val(),
'pwd': $("#id_pwd").val(),
'code': $("#code").val(),
'csrfmiddlewaretoken':'{{csrf_token}}'
},
success: function (data) {
console.log(data)
if(data.user){
location.href='/index/'}
else{
$(".errors").text(data.msg)} #可在顶端style上加css样式，变红色
}
})
})
</script>
</body>
</html>
