django使用django-simple-captcha完成图片验证码

1:需要下载包:

pip install  django-simple-captcha

2: 然后在settings的INSTALLED_APPS添加:

'captcha'

3: 需要生成数据库表

python manage.py migrate

4: 然后在urls中注册路由:

from captcha.views import captcha_refresh
from django.conf.urls import url,include

url("^captcha/",include('captcha.urls'))
url:地址是可以进行正则表达式的

5.在相应的app下创建一个forms文件:

from django import forms
from captcha.fields import CaptchaField     
class DynamicLoginForm(forms.Form):
    captcha=CaptchaField()

6:在处理图片验证码的view文件:
导入刚刚创建的forms类

from apps.users.forms import LoginForm,DynamicLoginForm
login_form=DynamicLoginForm()
        return render(request,"html/login.html",{
            "login_form":login_form
        })

7:在前端中渲染

{{ login_form.captcha }}
