php教程_如何用laravel生成sitemap

用laravel换一个思路，生成.xml动态链接，而不是保存文件到目录

1.配置routes，生成xml访问链接

2.根据项目逻辑生成sitemap

上代码：

配置routes

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

核心代码

<?php
namespace App\Http\Controllers\M;
use App\Http\Controllers\BaseController;
use App\Model\Bbs\Article;
use App\Model\Bbs\Ask;
use App\Model\Bbs\Thread;
use App\Model\Main\Video;
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('Content-type', 'text/xml');
    }
