    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

    # 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
    2.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.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"
