如何用laravel生成sitemap

之前用yaf和yii框架寫過sitemap：想法是根據需求產生.xml檔保存到專案指定目錄中。

用laravel換一個思路，生成.xml動態鏈接，而不是保存文件到目錄

1.配置routes，產生xml訪問鏈接

2.根據專案邏輯產生sitemap

上程式碼：

設定routes

    //sitemap
    Route::get('/sitemap/m/{type}.xml', 'SitemapController@siteMap');

核心程式碼

<?php

use App\Http\Controllers\BaseController;
use App\Model\Bbs\Article;
use App\Model\Bbs\Ask;
use App\Model\Bbs\Thread;

use App\Model\Garage\SeriesInfoModel;
//todo 补充其他模块
use Carbon\Carbon;
use Illuminate\Support\Facades\Cache;
class SitemapController extends BaseController
{
    //todo 写一个汇总文件
    public function siteMap($type)
    {
        $cacheKey = "site-" . $type;
        //2小时缓存 保证加载速度
        if (Cache::has($cacheKey)) {
            $siteMap = Cache::get($cacheKey);
        } else {
            $siteMap = $this->buildSiteMap($type);
            Cache::add($cacheKey, $siteMap, 120);
        }
        return response($siteMap)
            ->header(&#39;Content-type&#39;, &#39;text/xml&#39;);
