Jekyll - 将多个URL映射到同一个Jekyll文件

Question

我有一个Jekyll的自定义页面:我有一个news.markdown如下文件:

{% assign posts_per_page = 5 %}
{% for post in site.categories.ro offset:pagination_skip limit:posts_per_page %}
    ...
    {{ post.content }}
    ...
{% endfor %}
{% include nav.html %}

凡nav.html在_includes目录中,它看起来是这样的:

{% if pagination_skip %}
  {% capture pagination_skip %}
    {{pagination_skip | plus: posts_per_page}}
  {% endcapture %}
{% else %}
  {% assign pagination_skip = posts_per_page %}
{% endif %}

<div class="next">
  <a rel="prev" href="{{site.basepath}}ro/news/{{ pagination_skip }}">Next</a>
</div>

我想是的URL .../ro/news/5映射到的内容news.markdown,从而pagination_skip存在5.同样适用于10,15,无论如何.而且,.../ro/news/0应该尽可能相同.../ro/news/.

我能这样做吗？怎么样？

我想尽可能少地使用扩展程序.

你试图做错事。您想要动态处理 URL 参数。Jekyll 是一个静态网页生成器。所以你需要生成所有将被访问的页面。你可以用一个发电机来实现。请查看页面上的生成器部分https://github.com/mojombo/jekyll/wiki/Plugins

我为你想做的事情开发了一个生成器，它工作得非常好，我还创建了“上一个”和“下一个”按钮。请看一下并尝试一下。它适用于所有类别（不仅是ro类别），但您可以根据需要对其进行自定义。

生成器news.rbruby​​ 代码

module Jekyll

  class NewsPage < Page
    def initialize(site, base, dir, category, posts_number, posts_per_page, pagination_skip)
      @site = site
      @base = base
      @dir = dir
      @name = "news_#{pagination_skip}.html"

      self.process(@name)
      self.read_yaml(File.join(base, '_layouts'), 'news.html')
      self.data['category'] = category
      self.data['posts_per_page'] = posts_per_page
      self.data['pagination_skip'] = pagination_skip
      if pagination_skip != 0
        self.data['prev_pagination_skip'] = pagination_skip - posts_per_page
      end
      if pagination_skip + posts_per_page < posts_number
        self.data['next_pagination_skip'] = pagination_skip + posts_per_page
      end
    end
  end

  class NewsGenerator < Generator
  safe true
    def generate(site)
      if site.layouts.key? 'news'
        dir = site.config['category_dir'] || 'categories'
        site.categories.keys.each do |category|
          posts_number = site.categories[category].length
          pagination_skip = 0;
          posts_per_page = 5;
          begin
            write_news_page(site, File.join(dir, category), category, posts_number, posts_per_page, pagination_skip)
            pagination_skip += posts_per_page;
          end while pagination_skip < posts_number
        end
      end
    end

    def write_news_page(site, dir, category, posts_number, posts_per_page, pagination_skip)
      index = NewsPage.new(site, site.source, dir, category, posts_number, posts_per_page, pagination_skip)
      index.render(site.layouts, site.site_payload)
      index.write(site.dest)
      site.pages << index
    end
  end
end

news.html文件的布局

{% for post in site.categories[page.category] offset:page.pagination_skip limit:page.posts_per_page %}
  {{ post.content }}
{% endfor %}
{% include nav.html %}

包括导航nav.html

<div class="nav">
  {% if page.prev_pagination_skip %}
    <a rel="prev" href="{{site.basepath}}categories/{{page.category}}/news_{{page.prev_pagination_skip}}.html">Prev</a>
  {% endif %}
  {% if page.next_pagination_skip %}
    <a rel="next" href="{{site.basepath}}categories/{{page.category}}/news_{{page.next_pagination_skip}}.html">Prev</a>
  {% endif %}
</div>

尝试一下，如果您喜欢，请告诉我。
