Symfony2 强制 twig 输出 XML 格式的数据 [英] Symfony2 force twig to output XML formated data

问题描述

我正在使用 Symfony2 并努力使用 twig 以 XML 格式输出数据.相反，twig 只是将大量文本块扔到浏览器上，只有当右键单击查看源代码时，我才能看到布局良好的 XML.

I am using Symfony2 and struggling to use twig to output data in a XML format. Instead what happens twig just throws massive block of text on to the browser it is only when right click to view source i can see nicely laid out XML.

有什么办法可以强制 Twig 实际输出格式化的 XML 而不是文本块，而不必查看页面源...?

Is there any way I can force Twig to actually output formatted XML instead blok of text without having to view page source...?

sitemap.xml.twig:

sitemap.xml.twig:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
    <url>
        {% for entry in sitemapresp %}
            <loc>{{ entry['url'] }}</loc>
            <lastmod>{{ entry['date'] }}</lastmod>
            <changefreq>{{ entry['frequency'] }}</changefreq>
            <priority>{{ entry['priority'] }}</priority>

        {% endfor %}
    </url>
</urlset>

浏览器输出:

http://www.sitemappro.com/2015-01-27T23:55:42+01:00daily0.5http://www.sitemappro.com/download.html2015-01-26T17:24:27+01:00daily0.5

源视图输出:

    <?xml version="1.0" encoding="UTF-8"?>
    <urlset xmlns="http://www.google.com/schemas/sitemap/0.90">
      <url>
        <loc>http://www.sitemappro.com/</loc>
        <lastmod>2015-01-27T23:55:42+01:00</lastmod>
        <changefreq>daily</changefreq>
        <priority>0.5</priority>
      </url>
      <url>
        <loc>http://www.sitemappro.com/download.html</loc>
        <lastmod>2015-01-26T17:24:27+01:00</lastmod>
        <changefreq>daily</changefreq>
        <priority>0.5</priority>
      </url>
</urlset>

有什么建议...?

推荐答案

如果需要页面为 XML，则需要设置响应的内容类型.

If you need the page to be XML, you will need to set the content type of the response.

$response = new Response($this->render('sitemap.xml.twig'));
$response->headers->set('Content-Type', 'application/xml; charset=utf-8');
return $response;

如果您只希望页面的一部分在 HTML 页面中呈现代码，请使用:

If you only want part of the page to render the code in an HTML page, use:

{% autoescape %}
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
    <url>
        {% for entry in sitemapresp %}
            <loc>{{ entry['url'] }}</loc>
            <lastmod>{{ entry['date'] }}</lastmod>
            <changefreq>{{ entry['frequency'] }}</changefreq>
            <priority>{{ entry['priority'] }}</priority>

        {% endfor %}
    </url>
</urlset>
{% endautoescape %}
