[Laravel] Laravel的基本HTTP路由

?

使用Laravel的基本路由，實(shí)現(xiàn)get請求響應(yīng)，找到文件app/Http/routes.php

調(diào)用Route的靜態(tài)方法get()，實(shí)現(xiàn)get響應(yīng)，參數(shù)：string類型的路徑，匿名函數(shù)function(){}

匿名函數(shù)內(nèi)部，返回string數(shù)據(jù)

?

實(shí)現(xiàn)post，put，delete的請求，同上

?

實(shí)現(xiàn)get傳遞參數(shù)的路由，調(diào)用Route的靜態(tài)方法get()，參數(shù)：路徑，匿名函數(shù)

路徑，大括號包裹參數(shù)名，不含$，例如：’/user/{id}’

匿名函數(shù)，接收參數(shù)，例如：function($id){}

?

[Laravel] Laraval的基本控制器

?

在app/Http/Controllers目錄下，新建一個Index/IndexController.php

定義命名空間，namespace App\Http\Controllers\Index

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

定義IndexController繼承Controller

實(shí)現(xiàn)方法index，返回數(shù)據(jù)

定義路由指定控制器的行為，例如：Route::get("/index","Index\IndexController@index");，

注意命名空間部分，新建的控制器是在根命名空間下面，指定的時候添加自己新加的命名空間

[Laravel] Laravel的基本視圖

在目錄resources/views/下面，創(chuàng)建index/index.php

在控制器中使用函數(shù)view()來調(diào)用模板，參數(shù)：文件路徑（.分隔目錄），數(shù)據(jù)

路由：routes.php

控制器：IndexController.php

<?<span>php
