图片验证思维导图

 

 

 

 

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.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
