框架篇:5.自定义配置与路由
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:
//Application
...省略代码
public function handleRequest(Request $request)
{
$route = $request->resolve($this->_config['route']??[]);
$response = $request->runAction($route, $this->_config['defaultRoute']??true);
/**
* 执行结果赋值给$response->data,并返回给response对象
*/
if ($response instanceof Response) {
return $response;
}
throw new SaiException('Content format error');
}
...省略代码
...省略代码
public function runAction($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 )
