之前用yaf和yii框架写过sitemap：思路是根据需求生成.xml文件保存到项目指定目录中。
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
<?phpnamespace 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'); } /** * build the site map */ protected function buildsitemap($type) { $sitemapinfo = []; switch ($type) { case 'video': $sitemapinfo = $this->getvideoinfo(); break; case 'article': $sitemapinfo = $this->getarticleinfo(); break; case 'bbs': $sitemapinfo = $this->getbbsinfo(); break; case 'ask': $sitemapinfo = $this->getaskinfo(); break; case 'series': $sitemapinfo = $this->getseriesinfo();//车型库 break; } $lastmod = $sitemapinfo[0]['pub_time']; $xml = []; $xml[] = '<?xml version="1.0" encoding="utf-8"?' .
