如何用laravel生成sitemap
时间:2020-01-15 14:39
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
<?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'); } /** * 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"?' . '>'; $xml[] = '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:mobile="http://www.baidu.com/schemas/sitemap-mobile/1/">'; $xml[] = ' <url>'; $xml[] = " <loc>https://m.xxx.com</loc>"; $xml[] = " <lastmod>$lastmod</lastmod>"; $xml[] = ' <changefreq>daily</changefreq>'; $xml[] = ' <priority>0.8</priority>'; $xml[] = ' </url>'; foreach ($sitemapInfo as $sitemap) { $xml[] = ' <url>'; $xml[] = " <loc>{$sitemap['url']}</loc>"; $xml[] = " <mobile:mobile type=\"mobile\"/>"; $xml[] = " <lastmod>{$sitemap['pub_time']}</lastmod>"; $xml[] = " </url>"; } $xml[] = '</urlset>'; return join("\n", $xml); } /** * Return all the posts as $url => $date */ protected function getVideoInfo() { $videos = Video::where('pub_time', '<=', Carbon::now()) ->where('published', 2) ->where('is_del', 0) ->orderBy('id', 'desc') ->pluck('pub_time', 'id') ->all(); $res = $article = []; foreach ($videos as $id => $pub_time) { $article['id'] = $id; $article['pub_time'] = substr($pub_time, 0, 10); $article['url'] = "https://m.xxx.com/video_" . $id .
