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/">';
