我正在尝试从Slim框架中定义的路径构建动态下拉菜单，这是我的问题 - 有没有办法从某种数组访问所有定义的静态路由？
例如，如果我像这样定义我的路线：
// Index page: '/'
require_once('pages/main.php');
// Example page: '/hello'
require_once('pages/hello.php');
// Example page: '/hello/world'
require_once('pages/hello/world.php');
// Contact page: '/contact'
require_once('pages/contact.php');
每个文件都是一个单独的页面，看起来像这样
// Index page
$app->get('/', function ($request, $response, $args) {
// Some code
})->setName('index');
我想从某种数组中访问所有这些已定义的路由，然后使用该数组在我的模板文件中创建一个无序的HTML列表。
<ul>
<li><a href="/">Index</a></li>
<li><a href="/hello">Hello</a>
<ul>
<li><a href="/hello/world">World</a></li>
</ul>
</li>
<li><a href="/contact">Contact</a></li>
</ul>
每当我更改已定义的路线时，我希望此菜单随之改变。有没有办法实现这个目标？

快速搜索Router class in GitHub project for Slim会显示一个公共方法getRoutes()，它返回$this->routes[]路由对象数组。从路径对象中，您可以使用getPattern()方法获取路径模式：
$routes = $app->getContainer()->router->getRoutes();
// And then iterate over $routes
foreach ($routes as $route) {
echo $route->getPattern(), "<br>";
}

是。您可以在Slim中name your routes。这是以一种非常简单的方式完成的：
jQuery(function () {
// Create the chart
var chart = Highcharts.chart('container', {
credits: {
enabled: false
},
exporting: { enabled: true },
chart: {
type: 'column',
renderTo: 'sampleChart',
},
credit:{enabled:false},
title: {
text: 'Reviews'
},
lang: {
drillUpText: '◁ Back'
},
subtitle: {
text: 'Details of reviews'
},
xAxis: {
type: 'category',
labels:{
formatter: function() {
return (this.value.toString()).replace(/[^\da-zA-Z]/g,' ');
},
showInLegend: true,
},
title: {
text: 'Date of Reviews'
}
},
yAxis: {
allowDecimals: false,
title: {
text: 'Number of Reviews'
}
},
legend: {
// layout: 'vertical',
// backgroundColor: '#FFFFFF',
enabled: true,
floating: false,
shadow :false,
// align: 'left',
// verticalAlign: 'top',
// x: 90,
// y: 45,
labelFormatter: function () {
return (this.name).replace(/[^a-zA-Z0-9]/g,' ');
}
},
plotOptions: {
series: {
borderWidth: 2,
cursor: 'pointer',
groupPadding: 0.125,
dataLabels: {
enabled: true,
format: '{point.y}'
},
point: {
events: {
click: function (e) {
console.log(this)
}
}
}
},
},
tooltip: {
useHtml:true,
headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
//pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y}</b> of total<br/>',
formatter: function() {
if(this.point.text)
return '<b>'+this.point.text+'</b>';
return '<b>'+ this.point.name+'</b>';
}
},
series: [{
name: 'Years',
colorByPoint: true,
data:[{"name":"Audio-2016","y":64,"drilldown":"audio_2016"},{"name":"Text-2016","y":8,"drilldown":"text_2016"},{"name":"Video-2016","y":10,"drilldown":"video_2016"}] }],
drilldown: {
series: [{"name":"AUDIO_2016","id":"audio_2016","data":[{"name":"October-2016","y":54,"drilldown":"october_audio_2016"},{"name":"November-2016","y":10,"drilldown":"november_audio_2016"}]},{"name":"TEXT_2016","id":"text_2016","data":[{"name":"October-2016","y":7,"drilldown":"october_text_2016"},{"name":"November-2016","y":1,"drilldown":"november_text_2016"}]},{"name":"VIDEO_2016","id":"video_2016","data":[{"name":"October-2016","y":8,"drilldown":"october_video_2016"},{"name":"November-2016","y":2,"drilldown":"november_video_2016"}]},{"name":"OCTOBER_AUDIO_2016","id":"october_audio_2016","data":[{"name":"week-4","y":50,"drilldown":"week_4_october_audio_2016"},{"name":"week-1","y":4,"drilldown":"week_1_october_audio_2016"}]},{"name":"NOVEMBER_AUDIO_2016","id":"november_audio_2016","data":[{"name":"week-1","y":10,"drilldown":"week_1_november_audio_2016"}]},{"name":"OCTOBER_TEXT_2016","id":"october_text_2016","data":[{"name":"week-4","y":7,"drilldown":"week_4_october_text_2016"}]},{"name":"NOVEMBER_TEXT_2016","id":"november_text_2016","data":[{"name":"week-1","y":1,"drilldown":"week_1_november_text_2016"}]},{"name":"OCTOBER_VIDEO_2016","id":"october_video_2016","data":[{"name":"week-4","y":8,"drilldown":"week_4_october_video_2016"}]},{"name":"NOVEMBER_VIDEO_2016","id":"november_video_2016","data":[{"name":"week-1","y":2,"drilldown":"week_1_november_video_2016"}]},{"name":"WEEK_4_OCTOBER_AUDIO_2016","id":"week_4_october_audio_2016","data":[{"name":"26-October-2016_Inactive","y":13,"color":"#D6CBC9","text":""},{"name":"26-October-2016_Active","y":29,"color":"#FFD700","text":"Winner of the week"},{"name":"27-October-2016_Active","y":8,"color":null,"text":""}]},{"name":"WEEK_1_OCTOBER_AUDIO_2016","id":"week_1_october_audio_2016","data":[{"name":"02-October-2016_Inactive","y":1,"color":"#D6CBC9","text":""},{"name":"02-October-2016_Active","y":3,"color":"#FFD700","text":"Winner of the week"}]},{"name":"WEEK_4_OCTOBER_TEXT_2016","id":"week_4_october_text_2016","data":[{"name":"26-October-2016_Active","y":7,"color":"#FFD700","text":""}]},{"name":"WEEK_4_OCTOBER_VIDEO_2016","id":"week_4_october_video_2016","data":[{"name":"27-October-2016_Active","y":8,"color":"#FFD700","text":""}]},{"name":"WEEK_1_NOVEMBER_AUDIO_2016","id":"week_1_november_audio_2016","data":[{"name":"01-November-2016_Active","y":6,"color":"#FFD700","text":""},{"name":"03-November-2016_Inactive","y":2,"color":"#D6CBC9","text":""},{"name":"03-November-2016_Active","y":2,"color":null,"text":""}]},{"name":"WEEK_1_NOVEMBER_TEXT_2016","id":"week_1_november_text_2016","data":[{"name":"03-November-2016_Active","y":1,"color":"#FFD700","text":""}]},{"name":"WEEK_1_NOVEMBER_VIDEO_2016","id":"week_1_november_video_2016","data":[{"name":"07-November-2016_Active","y":2,"color":"#FFD700","text":""}]}],
}
});
现在您可以按名称获取URL：
$app->get('/hello', function($request, $response) {
// Processing request...
})->setName('helloPage'); // setting unique name for route
您也可以使用占位符命名路径：
$url = $app->getContainer()->get('router')->pathFor('helloPage');
echo $url; // Outputs '/hello'
这是确定的方法，因为如果您在模板中按名称引用路由，那么如果您需要更改URL，则只需要在路由防御中执行此操作。我发现这个特别酷。

根据沃尔夫的回答，我已经找到了解决办法。
在您定义路线的页面中，在所有路线下方，我们将使用我们定义的路线制作一个容器。
// Get ALL routes
// --------------
$allRoutes = [];
$routes = $app->getContainer()->router->getRoutes();
foreach ($routes as $route) {
array_push($allRoutes, $route->getPattern());
}
$container['allRoutes'] = $allRoutes;
这将创建一个包含所需路径的数组，以后我们可以在项目中使用。
然后，在您定义的路线中，您可以这样调用：
$app->get('/helloWorld', function ($request, $response, $args) {
print_r ($this->allRoutes);
})->setName('helloWorld');
这将输出
Array
(
[0] => /
[1] => /helloWorld
[2] => /someOtherRoute
...
)
这样我们就可以使用这个数组创建我们想要的任何东西。再次感谢沃尔夫！

正如我在亭亭玉立的issue中评论的那样：
$routes = array_reduce($this->app->getContainer()->get('router')->getRoutes(), function ($target, $route) {
$target[$route->getPattern()] = [
'methods' => json_encode($route->getMethods()),
'callable' => $route->getCallable(),
'middlewares' => json_encode($route->getMiddleware()),
'pattern' => $route->getPattern(),
];
return $target;
}, []);
die(print_r($routes, true));
