Django 入门

安装好后进入文件夹会看到里面Django为咱们建立好的文件里

 

manage.py 为咱们启动服务的文件  python manage.py runserver 8080(启动服务的时候默认是8000,后面加8080 能够给他设置启动服务的端口号)

db.sqlite3 这个文件是为咱们提取建立好的链接数据库的文件夹

 

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 

 

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

　#在自动化测试中，常常须要查找操做文件，好比说查找配置文件（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），常常要对大量文件和大量路径进行操做，这就依赖于os模块
