django 框架實現的使用者註冊、登入、退出功能示例
阿新 • • 發佈：2020-01-09
本文例項講述了django 框架實現的使用者註冊、登入、退出功能。分享給大家供大家參考，具體如下：
1 使用者註冊：
from django.contrib import auth
from django.contrib.auth.models import User
from django.views.decorators.csrf import csrf_exempt
from django.http import HttpResponseRedirect
# 使用者註冊
@csrf_exempt
def register(request):
errors = []
account = None
password = None
password2 = None
email = None
CompareFlag = False
if request.method == 'POST':
if not request.POST.get('account'):
errors.append('使用者名稱不能為空')
else:
account = request.POST.get('account')
if not request.POST.get('password'):
errors.append('密碼不能為空')
else:
password = request.POST.get('password')
if not request.POST.get('password2'):
errors.append('確認密碼不能為空')
else:
password2 = request.POST.get('password2')
if not request.POST.get('email'):
errors.append('郵箱不能為空')
else:
email = request.POST.get('email')
if password is not None:
if password == password2:
CompareFlag = True
else:
errors.append('兩次輸入密碼不一致')
if account is not None and password is not None and password2 is not None and email is not None and CompareFlag :
user = User.objects.create_user(account,email,password)
user.save()
userlogin = auth.authenticate(username = account,password = password)
auth.login(request,userlogin)
return HttpResponseRedirect('/blog')
return render(request,'blog/register.html',{'errors': errors})
2 使用者登入：
@csrf_exempt
def my_login(request):
errors =[]
account = None
password = None
if request.method == "POST":
if not request.POST.get('account'):
errors.append('使用者名稱不能為空')
else:
account = request.POST.get('account')
if not request.POST.get('password'):
errors = request.POST.get('密碼不能為空')
else:
password = request.POST.get('password')
if account is not None and password is not None:
user = auth.authenticate(username=account,password=password)
if user is not None:
if user.is_active:
auth.login(request,user)
return HttpResponseRedirect('/blog')
else:
errors.append('使用者名稱錯誤')
else:
errors.append('使用者名稱或密碼錯誤')
return render(request,'blog/login.html',{'errors': errors})
3 使用者退出：
def my_logout(request):
auth.logout(request)
return HttpResponseRedirect('/blog')
URL：
urlpatterns = [ url(r'^$',views.index,name='index'),url(r'^p/(?P<article_id>[0-9]+)/$',views.detail,name='detail'),url(r'^register/$',views.register,name='register'),url(r'^login/$',views.my_login,name='my_login'),url(r'^logout/$',views.my_logout,name='my_logout'),]
註冊 HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
{% if errors %}
<li>
{% for error in errors %}
<p style="color: red;">
{{error}}
</p>
{% endfor %}
</li>
{% endif %}
<table>
<form action="" method="post">{% csrf_token %}
<tr>
<td>
<label >使用者名稱:</label>
</td>
<td>
<input type = 'text' placeholder="輸入使用者名稱" name = 'account'>
</td>
</tr>
<tr>
<td>
<label >密碼:</label>
</td>
<td>
<input type = 'password' placeholder="輸入密碼" name = 'password'>
</td>
</tr>
<tr>
<td>
<label >確認密碼:</label>
</td>
<td>
<input type = 'password' placeholder="再次輸入密碼" name ='password2'>
</td>
</tr>
<tr>
<td>
<label>郵箱:</label>
</td>
<td>
<input type="email" placeholder="輸入郵箱" name = 'email'>
</td>
</tr>
<tr>
<td>
<input type = 'submit' placeholder="Login" value="登入">
</td>
</tr>
</form>
</table>
</body>
</html>
登入HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>登入</title>
</head>
<body>
{% if errors %}
<li>
{% for error in errors %}
<p style="color: red;">
{{error}}
</p>
{% endfor %}
</li>
{% endif %}
<table>
<form action="" method="post">{% csrf_token %}
<tr>
<td>
<label >使用者名稱:</label>
</td>
<td>
<input type = 'text' placeholder="輸入使用者名稱" name = 'account'>
</td>
</tr>
<tr>
<td>
<label >密碼:</label>
</td>
<td>
<input type = 'password' placeholder="輸入密碼" name = 'password'>
</td>
</tr>
<tr>
<td>
<input type = 'submit' placeholder="Login" value="登入">
</td>
</tr>
</form>
</table>
</body>
</html>
</body>
</html>
