本篇博客算是一个开头,接下来会持续更新使用Swift3.0开发服务端相关的博客.当然,我们使用目前使用Swift开发服务端较为成熟的框架Perfect来实现.Perfect框架是加拿大一个创业团队开发的,目前是Perfect2.0版本,关于Perfect框架,下方会详细的介绍.本篇博客会演示一个完整的Demo, 该Demo完全由Swift3.0开发,其中包括服务端和iOS客户端,数据库采用的是MySQL. 进一步说,本篇博客将会演示一个使用Swift3.0开发的记事本,当然该记事本的服务端和iO

Go语言有一个不(奇)错(葩)的设计,就是build constraints(构建约束).可以在源码中通过注释的方式指定编译选项,比如只允许在linux下,或者在386的平台上编译啊之类的:还可以通过文件名来约束构造,比如xxxx_linux.go,就是只允许在linux下编译,xxx_windows_amd64.go就是只允许在windows x64下编译. 构建约束可以在很多文件中使用,不单单是GO文件.但是必须要注意的是,通过注释实施构建约束的话,比如要放在文件的开头,要优先于空行或和其他
