phplarval胖模型,[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]&＃64;[方法]’);

//如下&＃xff1a;

Route::get(&＃39;/posts&＃39;,&＃39;\App\Http\Controllers\PostController&＃64;index&＃39;);

1.路由参数

Route::get(&＃39;/posts/{id}&＃39;,&＃39;\App\Http\Controllers\PostController&＃64;index&＃39;);

//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&＃xff1a;

Route::get(&＃39;/posts&＃39;,&＃39;\App\Http\Controllers\PostController&＃64;index&＃39;);

Route::get(&＃39;/posts/create&＃39;,&＃39;\App\Http\Controllers\PostController&＃64;index&＃39;);

Route::get(&＃39;/posts/{id}&＃39;,&＃39;\App\Http\Controllers\PostController&＃64;index&＃39;);

分组后&＃xff1a;

//参数一&＃xff1a;共有属性

Route::group([&＃39;prefix&＃39;&＃61;>&＃39;posts&＃39;],function (){

Route::get(&＃39;/&＃39;,&＃39;\App\Http\Controllers\PostController&＃64;index&＃39;);

Route::get(&＃39;/create&＃39;,&＃39;\App\Http\Controllers\PostController&＃64;index&＃39;);

Route::get(&＃39;/{id}&＃39;,&＃39;\App\Http\Controllers\PostController&＃64;index&＃39;);

});

3.绑定模型

绑定前:

Route::get(&＃39;/posts/{id}&＃39;,&＃39;\App\Http\Controllers\PostController&＃64;show&＃39;);

function show($id){

//模型是user,查找模型实体

$user &＃61; \App\User::find($id);

//进行操作

}

绑定后&＃xff1a;

//默认 user &＃61;> 表&＃xff1a;users &＃61;> 主键&＃xff1a;id

Route::get(&＃39;/posts/{user}&＃39;,&＃39;\App\Http\Controllers\PostController&＃64;show&＃39;);

function show(\App\User $user){

//进行操作

}
