1.用户认证
1.auth模块
from django.contrid import auth
2.authenticate()
提供了用户认证,验证用户名和密码是否正确,一般使用username password两个关键字参数
user_obj=auth.authenticate(username=user,password=pwd)
如果认证信息有效，会返回一个 User 对象。authenticate()会在User 对象上设置一个属性标识那种认证后端认证了该用户，且该信息在后面的登录过程中是需要的。
当我们试图登陆一个从数据库中直接取出来不经过authenticate()的User对象会报错的！！
3.用户登录
视图部分:
def login(request): if request.method=="GET": return render(request,"index.html") else: user=request.POST.get("user") pwd=request.POST.get("pwd") user_obj=auth.authenticate(username=user,password=pwd) if user_obj: auth.login(request,user_obj) return redirect("/books/") else: return redirect("/login/")

4.用户注册视图部分:
def reg(request): if request.method=="GET": return render(request,"reg.html") else: user=request.POST.get("user") pwd=request.POST.get("pwd") User.objects.create_user(username=user,password=pwd) return redirect("/login/")
