PHP DIY系列–一起手写一个api框架
我们已经开发完成,但我们还需要更多。比如自定义配置和路由。
app文件夹下新建Config.php
<?php /** *自定义配置 */ return [ 'debug' => false, 'route' => [ '' => 'demo/welcome', 'test' => 'demo/test', ], ];
|
新建DemoController(app/Https/Controllers目录下)
<?php /** * Demo控制器 */
namespace App\Https\Controllers;
use Library\Https\Controller;
class DemoController extends Controller { public function welcome($params) { return $this->response->json(['hello' => 'welcome']); }
public function test($params) { return $this->response->json($params); } }
|
修改入口文件index.php,加入加载配置代码:
... 省略代码
// 加载配置 $config = require SF_LIBRARY_PATH.'Config.php';
$appConfig = file_exists($appConfigPath = SF_APP_PATH.'Config.php') ? require $appConfigPath : []; $config = array_merge($config, $appConfig);
$config['debug'] = ($config['debug']?? SF_DEBUG);
...省略代码
|
解析路由部分也加入自定义路由处理:
// Application ...省略代码 public function handleRequest(Request $request) { $route = $request->resolve($this->_config['route']??[]);
$response = $request->runAction($route); /** * 执行结果赋值给$response->data,并返回给response对象 */ if ($response instanceof Response) { return $response; }
throw new SaiException('Content format error'); } ...省略代码
// Request ...省略代码 public function runAction($route) { if (array_key_exists($route, $this->_route)) { $route = $this->_route[$route]; }
$match = explode('/', $route); $match = array_filter($match); ...省略代码
|
保存后打开浏览器看看效果:


这里虽然有自定义路由,但是我们有时候需要禁止默认路由,所以我们不妨增加配置参数defaultRoute,用来控制是否开启默认路由。
我们修改一下路由解析的代码:
...省略代码
public function handleRequest(Request $request) { $route = $request->resolve($this->_config['route']??[]);
$response = $request->runAction($route, $this->_config['defaultRoute']??true);
if ($response instanceof Response) { return $response; }
throw new SaiException('Content format error'); }
...省略代码
|
...省略代码
public function runAction($route, $defaultRoute) { if (array_key_exists($route, $this->_route)) { $route = $this->_route[$route]; } elseif (!$defaultRoute) { throw new NotFoundException("route not found:".$route); } ...省略代码
|
我们在app下面的Config,加入:
return [ 'debug' => false, 'route' => [ '' => 'demo/welcome', 'test' => 'demo/test', ], 'defaultRoute' => false, ];
|
我们打开浏览器输入http://saif.com/login
报错如下:
Array
(
[line] => 137
[msg] => route not found:login
[code] => 404
[file] => library/Https/Request.php
)
