我安装了 SeoBundle 并配置了 bundle 以构建站点地图 ( docs)。

AppKernel.php:

new Sonata\SeoBundle\SonataSeoBundle(),
new Symfony\Cmf\Bundle\CoreBundle\CmfCoreBundle(),
new Symfony\Cmf\Bundle\SeoBundle\CmfSeoBundle(),

完整的包配置(config.yml):

sonata_seo:
    page:
        title: Erasmus internship – Training Experience
        metas:
            name:
                keywords: Erasmus Internships, Internship in Europe, International Internships, Erasmus+, Erasmus Entrepreneur, Student Internships, Internships Abroad, Student Placements
                description: Find Internships with Training Experience: Students can find internships & employment opportunities in Europe’s platform for internships. Search paid internships and placements abroad.
                viewport: width=device-width, initial-scale=1
                format-detection: telephone=no
                robots: index, follow
            property:
                'og:site_name': Training Experience
                'og:title': Erasmus internship – Training Experience
                'og:description': Find Internships with Training Experience: Students can find internships & employment opportunities in Europe’s platform for internships. Search paid internships and placements abroad."
                'og:url': https://www.trainingexperience.org
                'og:image': https://www.trainingexperience.org/bundles/index/images/tx-orange.png
            http-equiv:
                'Content-Type':         text/html; charset=utf-8
        head:
            'xmlns':              http://www.w3.org/1999/xhtml
            'xmlns:og':           http://opengraphprotocol.org/schema/

cmf_seo:
    title: seo.title
    description: seo.description
    sitemap:
        enabled: true
    content_listener:
        enabled: false

将路由添加到 routing.yml:

sitemaps:
    prefix: /sitemaps
    resource: "@CmfSeoBundle/Resources/config/routing/sitemap.xml"

现在，当我访问 /sitemaps/sitemap.xml 时，它已打开，但未列出任何网址:

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xhtml="http://www.w3.org/1999/xhtml"></urlset>

我可能遗漏了什么？

最佳答案

对于 sitemat 上的项目来说重要的是，它们有一个匹配的(允许的，和站点地图名称)作为内容。大多数内容未加载。为此，您的内容必须实现 \Symfony\Cmf\Bundle\SeoBundle\SitemapAwareInterface，这会强制您实现并填充标志。您可以在测试中找到示例:SitemapAwareContent:

<?php

    /**

     */
    protected $locale;

    /**

    protected $routes;

    /**

    protected $title;

    public function __construct()
    {
        $this->routes = new ArrayCollection();
    }

    /**
     * @param string $sitemap
     *
     * @return bool
     */
    public function isVisibleInSitemap($sitemap)
    {
        return $this->isVisibleForSitemap;
    }

    /**

     */
    public function setIsVisibleForSitemap($isVisibleForSitemap)
    {
        $this->isVisibleForSitemap = $isVisibleForSitemap;

        return $this;
    }

    /**
     * Add a route to the collection.
     *
     * @param Route $route
     */
    public function addRoute($route)
    {
        $this->routes->add($route);
    }

    /**
     * Remove a route from the collection.
     *
     * @param Route $route
     */
    public function removeRoute($route)
    {
        $this->routes->removeElement($route);
    }

    /**
     * Get the routes that point to this content.
     *
     * @return Route[] Route instances that point to this content
     */
    public function getRoutes()
    {
        return $this->routes;
    }

    /**
     * @return string|bool the locale of this model or false if
     *                     translations are disabled in this project
     */
    public function getLocale()
    {
        return $this->locale;
    }

    /**
     * @param string|bool $locale the local for this model, or false if
     *                            translations are disabled in this project
     */
    public function setLocale($locale)
    {
        $this->locale = $locale;
    }
}

您还会看到实现接口(interface)并不是唯一的任务，您还必须设置原则映射。这样做，默认加载程序将获取您的文档并查看它们(它们现在可见)。 但是你可以自己实现加载器、投票器(另一个要选择的决策项)和猜测器(填充额外数据)。因此，您可以决定哪些内容在哪个(您可以有多个)站点地图上可见。

documentation目前仅显示加载器、投票器和猜测器的过程，因此我们应该为默认可见性标志和默认用法插入一些提示。所以我创建了一个 issue .如果能在那里得到一些反馈也很好。
