Atom XML Parsing Error: prefix not bound to a namespace

Question

我正在尝试根据 Laracasts 教程编写一个 XML 馈线。我需要添加博客 post 缩略图作为媒体元素，但我在 media:content

开头收到错误消息

    XML Parsing Error: prefix not bound to a namespace
                 <media:content url="https:/sirtcantalilar.com/uploads/img/posts/2/Paris_train_station.jpg">
   --------------^

我的 XML 视图与 Laracast 中的一样：

{{ '<?xml version="1.0" encoding="utf-8" ?>' }}
<feed xmlns="http://www.w3.org/2005/Atom">
    <title>Sirtcantalilar Topluluğu</title>
    <subtitle></subtitle>
    <updated>{{ Carbon\Carbon::now()->toATOMString() }}</updated>
    <author>
        <name></name>
    </author>
    <id>tag:sirtcantalilar.com, {{date('Y')}}:/feed</id>

    @foreach($posts as $post)
        <entry>
            <author>
                <name>{{$post->author->name}}</name>
            </author>
            <title>{{ $post->title }}</title>
            <link> {{ URL::route('view-post', $post->slug) }}</link>
            <id>{{ post_tag_uri($post)}}</id>
            <summary>{{$post->minicontent}}</summary>
             <category term="Blog"/>
             <content type="html"><![CDATA[{{$post->content}}]]></content>

                 <media:content url="https:/sirtcantalilar.com/uploads/img/posts/{{$post->id}}/{{$post->thumbnail->name}}">
                  <media:thumbnail url="https:/sirtcantalilar.com/uploads/img/posts/{{$post->id}}/thumb-{{$post->thumbnail->name}}" type="image/jpeg"/>
                <media:credit>Image{{$post->id}} attribution</media:credit>
                  <media:title>Image{{$post->id}} caption</media:title>
                  <media:text>Image{{$post->id}} alt-text</media:text>
                </media:content> 
        </entry>
    @endforeach

</feed>

你能帮帮我吗？

Answer 1

Atom 提要中的 media 前缀应引用 MediaRSS namespace。您将默认命名空间定义为带有 xmlns="http://www.w3.org/2005/Atom" 的 Atom，但没有定义 media 前缀。您需要添加定义..

<feed 
  xmlns="http://www.w3.org/2005/Atom" 
  xmlns:media="http://search.yahoo.com/mrss/">
