1,1 Django 缓存设置
django的六种缓存（mysql+redis） ：https://www.cnblogs.com/xiaonq/p/7978402.html#i6
1,2 安装Django缓存模块
pip install django-redis==4.12.1
1,3 syl/settings.py中配置缓存
CACHES = {
‘default‘: {
‘BACKEND‘:"django_redis.cache.RedisCache",
‘LOCATION‘:"redis://127.0.0.1:6379/0",
‘OPTIONS‘ : {
"CLIENT_CLASS" : "django_redis.client.DefaultClient",
} },
‘session‘ : {
‘BACKEND‘:"django_redis.cache.RedisCache",
‘LOCATION‘:"redis://127.0.0.1:6379/1",
‘OPTIONS‘ : {
"CLIENT_CLASS" : "django_redis.client.DefaultClient",
} },
"img_code": {
‘BACKEND‘:"django_redis.cache.RedisCache",
‘LOCATION‘:"redis://127.0.0.1:6379/2",
‘OPTIONS‘ : {
"CLIENT_CLASS" : "django_redis.client.DefaultClient",
}
}
SESSION_ENGINE = ‘django.contrib.sessions.backends.cache‘
# 配置session使用redis存储
SESSION_CACHE_ALIAS = "session"
#配置session存储的位置 : 使用cache中的 session配置
2, 新建应用verifications
1,图形验证码
2,短信验证码
3,邮件验证
在apps文件夹下新建应用: verifications
python ../manage.py startapp verifications
在 syl 下的settings里面配置应用
INSTALLED_APPS = [
‘verifications.apps.VerificationsConfig‘,
]
在urls中添加路由
path(‘verify‘, include(‘verifications.urls‘)),
添加子路由
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/ccaptcha/captcha.py 右键运行就可生成验证码
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):
uuid = request.GET.get(‘uuid‘)
if not uuid:
return HttpResponseForbidden(‘uuid无效‘)
text, image = captcha.generate_captcha()
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)
return HttpResponse(image, content_type=‘image/jpg‘)
