python通過captcha實作驗證碼的功能

1、安裝django-simple-captcha

pip install django-simple-captcha
           

2、打開settings.py在INSTALLED_APPS中配置

INSTALLED_APPS = [
	'captcha',
]
           

3、打開urls.py在urlpatterns中配置url

urlpatterns = [
    path('captcha',include('captcha.urls')),
]
           

4、遷移同步，生成captcha所依賴的表

python manage.py makemigrations
python manage.py migrate
           

5、将captcha字段在form類當中進行設定

from django import forms
from captcha.fields import CaptchaField
class UserRegisterForm(forms.Form):
    email = forms.EmailField(required=True)
    password = forms.CharField(required=True,min_length=3,max_length=15,error_messages={
        'required':'密碼必須填寫',
        'min_length':'密碼不得小于3位',
        'max_length':'密碼不得大于15位'
    })
    captcha = CaptchaField(error_messages={
        'invalid': '驗證碼錯誤'
    })
           

6、背景邏輯裡面，在get請求中執行個體化form,将form對象傳回到頁面

def user_register(request):
	if request.method == 'GET':
		user_register_form = UserRegisterForm()
		return render(request,'register.html',{
			'user_register_form':user_register_form
		})
           

7、在前端頁面上通過{{ user_register_form.captcha }}擷取驗證碼
