[PHP] Laravel实用入门：路由和绑定模型

一、Laravel路由

写在routes的web.php

Route::get(‘/’,’[控制器]@[方法]’);
//如下：
Route::get('/posts','\App\Http\Controllers\PostController@index');

1.路由参数

Route::get('/posts/{id}','\App\Http\Controllers\PostController@index');

//在PostController里面
function index($id){
    //在PostController中$id就等于上面的
}

2.路由分组

分组前：

Route::get('/posts','\App\Http\Controllers\PostController@index');
Route::get('/posts/create','\App\Http\Controllers\PostController@index');
Route::get('/posts/{id}','\App\Http\Controllers\PostController@index');

分组后：

//参数一：共有属性
Route::group(['prefix'=>'posts'],function (){
    Route::get('/','\App\Http\Controllers\PostController@index');
    Route::get('/create','\App\Http\Controllers\PostController@index');
    Route::get('/{id}','\App\Http\Controllers\PostController@index');
});

3.绑定模型

绑定前:

Route::get('/posts/{id}','\App\Http\Controllers\PostController@show');

function show($id){
    //模型是user,查找模型实体
    $user = \App\User::find($id);
    //进行操作
}

绑定后：

//默认  user => 表：users => 主键：id 
Route::get('/posts/{user}','\App\Http\Controllers\PostController@show');

function show(\App\User $user){
    //进行操作
}
