Laravel是一种基于php的MVC web开发框架

php artisan make:controller NAME//创建一个名字为name的controller

路由：routes/web.php

Route::get('/students','StudentController@index');

控制器：app/HTTP/Controllers（可以直接用命令行生成）

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class testcontrol extends Controller
{
    //
}

模型：app/student.php

视图：resources/views/student/index.blade.php

 目录结构：

 

# 对参数局部约束
Route::get('user/{id}', function ($id) {
    //
})->where('id', '[0-9]+');

Route::get('user/{id}/{name}', function ($id, $name) {
    //
})->where(['id' => '[0-9]+', 'name' => '[a-z]+']);

# 全局约束
// RouteServiceProvider
public function boot()
{
    Route::pattern('id', '[0-9]+');

    parent::boot();
}

Route::get('user', [\App\Http\Controllers\UserController::class, 'index']);
//（laravel 8.0）

composer create-project laravel/laravel=8.* --prefer-dist blog
//创建项目

---

全局约束

// app/http/provider/RouteServiceProvider
public function boot()
{
    Route::pattern('id', '[0-9]+');

    parent::boot();
}

添加中间件

Route::middleware('throttle:60,1')->group(function () {
    Route::get('/user', function () {
        //
    });
});    //1分钟只能访问60次

 

Route::middleware('throttle:60,1')->group(function () {
    Route::get('/user', function () {
        //
    });
});     // middleware('throttle:10|60,1')

Route::get('/user', function () {
        //
})->middleware('auth:api');

Route::middleware(['first', 'second'])->group(function () {
    Route::get('/', function () {
        // 使用 `first` 和 `second` 中间件
    });

    Route::get('user/profile', function () {
        // 使用 `first` 和 `second` 中间件
    });
});
