.Net Core 开发电商后端API 从0到精通吃透RESTful

XZ:.Net Core 开发电商后端API 从0到精通吃透RESTful

随着前后端分离成为市场主流，使用RESTful风格构建企业级应用已经是行业共识，但市场上对RESTful风格的认知及开发能力却参差不齐。本课程通过开发“慕课旅游网”项目，带领大家吃透RESTful思想，真正掌握高成熟度（HATEOAS超媒体引擎）级别RESTful API的开发技能。课程项目采用.Net Core框架，以开源、轻量、跨平台优势受到技术市场欢迎，是极其适合网站后端开发的热门技术框架。

适合人群
向往极致RESTful风格开发；
对.Net Core开发感兴趣的在校学生、初或中级程序员
技术储备要求
熟悉C#基础语法
