GoFrame 是一个开源的、高性能的 Web 开发框架,它是基于 Go 语言实现的,可以帮助开发者快速构建出高性能的 Web 应用。GoFrame 提供了一系列 API,可以帮助开发者快速实现各种功能。
GoFrame 的 API 主要分为三大部分:应用程序框架、数据库访问层和 Web 服务器。应用程序框架包含了一些常用的工具,如日志记录、配置文件读写、HTTP 请求处理、JSON 数据处理等;数据库访问层包含了对 MySQL、PostgreSQL 等数据库的访问封装;Web 服务器包含了对 HTTP 和 HTTPS 的封装,以及对 URL 路由的处理。
// 初始化 App app := goframe.NewApp() // 注册路由 app.RegisterRouter("/", &IndexController{}) // 运行 App app.Run()
GoFrame 的 API 非常易用,使用者只需要几行代码就能实现一个 Web 应用。上面这个例子中,我们使用 goframe.NewApp() 方法来初始化一个 App 对象;然后使用 app.RegisterRouter() 方法来注册一个 URL 路径到 IndexController 的映射关系;最后使用 app.Run() 方法来运行 App。
GoFrame 的 API 非常强大而且易于使用,它不仅可以帮助开发者快速实现 Web 功能,而且还有很多高性能特性。例如 GoFrame 有一套优化的 HTTP 处理流程;还有一套优化的数据库访问流程;还有一套优化的 URL 路径处理流程。所有这些特性都是 GoFrame API 的重要部分。
框架校验组件内置了数十项常用的校验规则。
校验规则涉及到联合校验的场景时,规则中关联的参数名称会自动按照不区分大小写且忽略特殊字符的形式进行智能匹配。
