django 验证码

1.django 缓存设置

django的六种缓存(mysql+redis) :https://www.cnblogs.com/xiaonq/p/7978402.html#i6

1.1 安装Django缓存模块

pip install django-redis==4.12.1

1.2 syl/settings.py 中配置缓存

 

 

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}

  

# 缓存配置
CACHES = {
  # django存缓默认位置,redis 0号库
  # default: 连接名称
    "default": {
    "BACKEND": "django_redis.cache.RedisCache",
    "LOCATION": "redis://127.0.0.1:6379/0",
    "OPTIONS": {
      "CLIENT_CLASS": "django_redis.client.DefaultClient",
    }
  },
  # django session存 reidis 1 号库(现在基本不需要使用)
  "session": {
    "BACKEND": "django_redis.cache.RedisCache",
    "LOCATION": "redis://127.0.0.1:6379/1",
    "OPTIONS": {
      "CLIENT_CLASS": "django_redis.client.DefaultClient",
    }
  },
  # 图形验证码,存redis 2号库
  "img_code": {
    "BACKEND": "django_redis.cache.RedisCache",
    "LOCATION": "redis://127.0.0.1:6379/2",
    "OPTIONS": {
      "CLIENT_CLASS": "django_redis.client.DefaultClient",
    }
  }
}
# 配置session使用redis存储
SESSION_ENGINE = "django.contrib.sessions.backends.cache"
# 配置session存储的位置: 使用cache中的 session配置
SESSION_CACHE_ALIAS = "session

 2.新建应用verifications 

  • 图形验证码
  • 短信验证码
  • 邮件验证
'''2.1 在apps文件夹下新建应用: verifications'''
python ../manage.py startapp verifications # 切换到apps文件夹下执行创建命令

  

'''2.2 在syl/settings.py中添加应用'''
INSTALLED_APPS = [
'verifications.apps.VerificationsConfig',
]
'''2.3 在syl/urls.py主路由中添加'''
path('verify/', include('verifications.urls')),
'''2.4 添加子路由: verifications/urls.py'''
from django.urls import path
from . import views
urlpatterns = [
# path('image_codes/', views.ImageCodeView.as_view())
]

  3.图形验证码captcha使用

  • 1.下载captcha压缩包captcha.zip,放到项目packages文件夹下
  • capecha在我的文件下载
  • .解压captcha.zip放到syl/libs文件夹下
  • 3.解压文件中的syl/libs/captcha/captcha.py 右键运行即可生成图片验证码 unzip xxx.zip

4.在verifications/views.py中使用

from django.http import HttpResponse, HttpResponseForbidden
from django.views import View
from django_redis import get_redis_connection
from libs.captcha.captcha import captcha
class ImageCodeView(View):
  def get(self, request):
    # 1.接收数据
    uuid = request.GET.get('uuid')
    # 2.校验数据
    if not uuid:
      return HttpResponseForbidden('uuid无效')
    # 3.处理业务
    # 获取图片文本内容和图片二进制代码
    text, image = captcha.generate_captcha()
    # 4.把uuid和图片文本存入redis
    redis_client = get_redis_connection('img_code') # 获取redis客户端
    # 5.写入redis(是字符串)
    redis_client.setex(uuid, 60 * 5, text)
    # 6.返回响应图片
    return HttpResponse(image, content_type='image/jpg')

 5.测试验证码接口 

http://192.168.56.100:8888/verify/image_codes/?uuid=66ea64aa-fbe6-11ea-a3d3-
005056c00008

  

127.0.0.1:6379># select 2
OK
127.0.0.1:6379[2]># keys *
1) "66ea64aa-fbe6-11ea-a3d3-005056c00008"
127.0.0.1:6379[2]># get 66ea64aa-fbe6-11ea-a3d3-005056c00008
"JEZ6
