系列文章---框架篇:5.自定义配置与路由


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, $this->_config['defaultRoute']??true);
/**
* 执行结果赋值给$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
)
