Django 入门

安装好后进入文件夹会看到里面Django为我们创建好的文件里

manage.py 为我们启动服务的文件  python manage.py runserver 8080(启动服务的时候默认是8000,后面加8080 可以给他设置启动服务的端口号)

db.sqlite3 这个文件是为我们提取创建好的连接数据库的文件夹

进入mysite内

 __init__.py 为初始化文件

settings.py 是配置文件

urls.py 是设置路由文件

wsgi.pt 

我们进入settings.py看一下相关配置（我在下图已经把相关配置对应的作用标准上备注）

　#在自动化测试中，经常需要查找操作文件，比如说查找配置文件（从而读取配置文件的信息），查找测试报告（从而发送测试报告邮件），经常要对大量文件和大量路径进行操作，这就依赖于os模块

#定义根目录
