[Laravel] Laravel的根本使用

[Laravel] Laravel的基本使用

[Laravel] Laravel的基本HTTP路由

 

使用Laravel的基本路由，实现get请求响应，找到文件app/Http/routes.php

调用Route的静态方法get()，实现get响应，参数：string类型的路径，匿名函数function(){}

匿名函数内部，返回string数据

 

实现post，put，delete的请求，同上

 

实现get传递参数的路由，调用Route的静态方法get()，参数：路径，匿名函数

路径，大括号包裹参数名，不含$，例如：’/user/{id}’

匿名函数，接收参数，例如：function($id){}

 

[Laravel] Laraval的基本控制器

 

在app/Http/Controllers目录下，新建一个Index/IndexController.php

定义命名空间，namespace App\Http\Controllers\Index

引入Controller基本控制器，use App\Http\Controllers\Controller

定义IndexController继承Controller

实现方法index，返回数据

定义路由指定控制器的行为，例如：Route::get("/index","Index\[email protected]");，

注意命名空间部分，新建的控制器是在根命名空间下面，指定的时候添加自己新加的命名空间

 

[Laravel] Laravel的基本视图

在目录resources/views/下面，创建index/index.php

在控制器中使用函数view()来调用模板，参数：文件路径（.分隔目录），数据

 

路由：routes.php
