Django-simple-captcha模快
1.下载安装：
window命令行输入：pip install django-simple-captcha ; pip install pillow
2.添加captcha：在setting中找到app再添加。
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'app01.apps.App01Config',
'captcha',
]
# 执行命令进行数据迁徙，会发现数据库中多了一个 captcha_captchastore 的数据表 python manage.py migrate
3.添加路由：在urls.py中添加对应的路由。
from django.contrib import admin
from django.urls import path, include
from app01 import views
urlpatterns = [
path('admin/', admin.site.urls),
path('captcha', include('captcha.urls')),
path('home/', views.home)
]
4.添加form表单：在app目录下创建forms.py。
from django import forms
from captcha.fields import CaptchaField
class UserForm(forms.Form):
username = forms.CharField(
label='用户名', # 在表单里表现为 label 标签
max_length=128,
widget=forms.TextInput(attrs={'class': 'form-control'}) # 添加 css 属性
)
captcha = CaptchaField(
label='验证码',
required=True,
error_messages={
'required': '验证码不能为空'
}
)
5.视图函数：在view.py中完成home函数。
from django.shortcuts import render
# Create your views here.
from app01.forms import UserForm
def home(request):
register_form = UserForm(request.POST)
if register_form.is_valid():
pass
register_form = UserForm()
return render(request, 'index.html', {'register_form': register_form})
6.前端渲染：在templates目录下创建index.html。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="#" method="post">
{{ register_form.captcha.label_tag }}
{{ register_form.captcha }}
</form>
</body>
</html>
7. 运行结果：python manage.py runserver
