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 AppHttpControllersM;
use AppHttpControllersBaseController;
use AppModelBbsArticle;
use AppModelBbsAsk;
use AppModelBbsThread;
use AppModelMainVideo;
use AppModelGarageSeriesInfoModel;
//todo 补充其他模块
use CarbonCarbon;
use IlluminateSupportFacadesCache;
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');
 }
