Controller definition
The class name is the same as the file name,
Rendering output
Rendering output uses return output
<?php namespace app\admin\controller;
use app\admin\model\User;
class Index
{
public function Index(){
$data = array(
'ming' => 'ming',
'ming' => 'xiao'
);
return json($data);
}
}Copy after login
At this time, the page renders a json file
The code cannot be interrupted in the controller. .
Use halt output
<?php namespace app\admin\controller;
use app\admin\model\User;
class Index
{
public function Index(){
$data = array(
'ming' => 'ming',
'ming' => 'xiao'
);
halt("输出测试");
return json($data);
}
}Copy after login
Use halt output
Multi-level controller
Multi-level controller Multi-level controller directly Use
<?php namespace app\admin\controller\Index;
class Blog
{
public function index(){
}
public function read($id){
var_dump(url('index/blog/read', ['id' => 5, 'name' => 'ming']));
return $id;
}
}Copy after login
in the namespace to define the sub-controller Blog under the Index namespace
Directory structure
Define routing rules
<?php use think\facade\Route; Route::rule('blog/:id', 'index.blog/read'); Route::rule('/', 'Index/index');
Copy after login
Access the blog directory under the index route
Basic Controller
The controller will have a basic controller
The system will provide a
app\BaseController
Copy after login
Basic Controller
The directory files are as follows
All controls have a basic control class
appBaseController
Because it is a multi-application mode. . Move the basic class to the directory
Change the namespace
namespace app\index\controller; use think\App; use think\exception\ValidateException; use think\Validate;
Copy after login
<?php namespace app\index\controller;
use think\Request;
class Index extends BaseController
{
/**
* 显示资源列表
*
* @return \think\Response
*/
public function index()
{
$action = $this->request->action();
$path = $this->app->getBasePath();
var_dump($action);
var_dump($path);
}
/**

* @return \think\Response
*/
public function create()
{
//

/**

public function save(Request $request)

public function update(Request $request, $id)
{
//
}
/**
* 删除指定资源
*
* @param int $id
* @return \think\Response
*/
public function delete($id)
{
//
}
}Copy after login
Output content
string(5) "index" string(43) "/home/ming/PhpstormProjects/untitled12/app/"
Copy after login

Register resource routing
Route::resource('blog', 'Blog');Copy after login
Controller middleware
Write the controller
<?php namespace app\index\middleware;
class Hello
{
public function handle($request, \Closure $next){
$request->hello = 'ming';
return $next($request);
}
}Copy after login
Use routing to register the controller
<?php use think\facade\Route; Route::rule('ming', 'index/index')->middleware( [ app\index\middleware\Hello::class ] );
Copy after login
Visit http://localhost:8082/index/ming
If ming
appears, it means the middleware registration is successful .
