模拟实现web版微信
1. 新建一个django项目 wechat
2. 在wechat项目下新建一个文件夹 static
3. 在wechat应用下的settings.py文件新增静态文件路径
STATICFILS_DIRS = (
os.path.join(BASE_DIR,'static')
)
4. 将jquery拷贝到static文件夹中
5. 新建一个应用 web
6. 在wechat应用下的urls.py文件中配置路由
from django.conf.urls import url
from django.contrib import admin
from web import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^login/$', views.login),
url(r'^polling/$', views.long_polling),
url(r'^index/$', views.index),
url(r'^contact_list/$', views.contact_list),
url(r'^send_msg/$', views.send_msg),
url(r'^get_msg/$', views.get_msg),
]
7. 在web应用下的views.py文件中书写相关函数
