【问题描述】：

我正在尝试制作一个简单的 rss 提要，但问题是当我运行文件时说你想打开 rss.php ...

这里的代码可能是我做错了什么？我把它放在这种格式只是为了看看它的工作原理。

<?php
header('Content-Type: application/rss+xml; charset=utf-8');
?>
&#60;?xml version='1.0' encoding='ISO-8859-1'?&#62;
<rss version='2.0'>
<channel>
<title>feed title</title>

【参考方案1】：

你应该输出真实的<?xml version='1.0' encoding='ISO-8859-1'?>，而不是实体化的版本。既然是php自带的<?，echo就在header后面有问题：

<?php
//header('Content-Type: application/xml');
header('Content-Type: application/rss+xml; charset=utf-8');
echo '<?xml version="1.0" encoding="utf-8"?>';
?>
<rss version='2.0'>

【讨论】：

我需要在刚买的这台 MacBook 上磨练我的打字速度。 +1

【参考方案2】：

Firefox 没有在标头中获取内容类型：application/rss+xml

虽然是正确的，formally、text/xml 似乎仍然是相当多的 rss 生成器和浏览器的标准

尝试将标题更改为

header('Content-Type: text/xml; charset=utf-8');
