Laravel router

构建基本路由只需要一个 URI 与一个 闭包

路由文件地址 routes文件夹 包含 api.php channels.php console.php web.php

web.php

Route::get('/', function () {
    return view('welcome');
});
方式
Route::get($uri, $callback);
Route::post($uri, $callback);
Route::put($uri, $callback);
Route::patch($uri, $callback);
Route::match(['请求方式']$uri, $callback);
Route::delete($uri, $callback);
Route::options($uri, $callback);
Route::any($uri, $callback);

根目录打开命令行

php artisan make:controller MyController

系统自动生成 app/Http/Controllers/MyController

//建立方法

	public function get(){
		return "get";
	}
	public function post(){
		return "post";
	}
	public function put(){
		return "put";
	}
	public function patch(){
		return "patch";
	}
	public function option(){
		return "option";
	}
	public function delete(){
		return "delete";
	}
	public function match(){
		return "match['post','get']";
	}
	public function any(){
		return "any ['all']";
	}

//定义路由 web.php
Route::get('/user/get','MyController@get');
Route::post('/user/post','MyController@post');
Route::put('/user/put','MyController@put');
Route::patch('/user/patch','MyController@patch');
Route::options('/user/option','MyController@option');
Route::delete('/user/delete','MyController@delete');
Route::match(['get','post'],'/user/match','MyController@match');
Route::any('/user/any','MyController@any');

因为有CSRF保护机制练习前需要关闭保护

https://learnku.com/docs/laravel/7.x/csrf/7460

中间件下的 app/Http/Middleware/VerifyCsrfToken.php

 protected $except = [
        //配置servername 
        'http://{servername}/user/*',
    ];
}

使用 PostMan请求

---

redirect 路由重定向

Route::get('log/here','LogController@here');
Route::get('log/there','LogController@there');
Route::redirect('log/here','/log/there');

view路由视图

Route::view('/view','view',['name'=>'jon']);

视图取值  {{ name }}

路由参数 正则验证 {name?}可为空，可设置默认值

Route::get('/get/{id}/{name?}',function($id,$name='tom'){
	return "UserID:".$id." Username:".$name;
});

设置全局正则 匹配 参数 id 必须整数 ‘[0-9]+’ 的正则

打开文件 app\Providers\RouteServiceProvider.php

public function boot(){
    //加入这个限制所有变量参数id 的验证
	Route::pattern('id','[0-9]+');
	parent::boot();
}

行内正则验证 aid

Route::get('/bl/{aid}',function($aid){
	return "UserID:".$aid;
})->where('aid','[0-9]+');

隐式绑定官方例子

Route::get('/user/{user}',function(App\User $user){
	return $user->name;
});

新建一个表测试一下

CREATE TABLE `contents` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` varchar(222) DEFAULT NULL,
  `content` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

创建model

php artisan make:model Content

打开model 设置绑定的条件

public function getRouteKeyName(){
	//这个地方可以定义任意contents表的段
	return 'id';
}

添加路由 ，有数据返回对应值，无数据 返回404

Route::get('/content/{content}',function(App\Content $content){	 
	return $content->title;
});

有隐式就有显示

显示绑定

//这里面定义的 $user 对应 
Route::get('/user/{user}',function($user){
	dd($user->name);
});

RouteServiceProvider.php 通过这里给{user}绑定 \App\User

public function boot()
{ 
	parent::boot();
    //顶一个 user 对应 \app\User
    Route::model('user', \App\User::class);
}
