背景:

seo的同事要批量提交xml格式的数据到搜索引擎,目前项目用laravel框架开发的,所以就有了这篇文章的诞生了。网上有不少关于php输出xml格式的例子,小弟不才也搬过,只是在php文件上面测试是没问题的,把它搬到laravel框架里面,就有有坑了,主要原因是header头的问题。

laravel框架怎么返回xml格式数据?

如果用header(“Content-type: text/xml”);

这样的话是没有效果的,会提示这样的错误:

This page contains the following errors:

error on line 14 at column 6: XML declaration allowed only at the start of the document

Below is a rendering of the page up to the first error.

laravel框架在输出xml的时候会自行用text/html方式返回数据,解决办法:

需要return response($xml,200)->header(“Content-type”,“text/xml”);这样的方式才能改变header头

laravel返回xml数据格式例子:

 public function index(Request $request){
        $data_array = array(
            array(
                'title' => 'title1',
                'content' => 'content1',
                'pubdate' => '2009-10-11',
            ),
            array(
                'title' => 'title2',
                'content' => 'content2',
                'pubdate' => '2009-11-11',
            )
        );
        $title_size = 1;
        $xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n";
        $xml .= "<article>\n";
        foreach ($data_array as $data) {
            $xml .= $this->create_item($data[&#39;title&#39;], $title_size, $data[&#39;content&#39;], $data[&#39;pubdate&#39;]);
        }
        $xml .= "</article>\n";
        #echo $xml;
        return response($xml,200)->header("Content-type","text/xml");
    }
 /**

  */
    private function create_item($title_data, $title_size, $content_data, $pubdate_data)
    {
        $item = "<item>\n";
        $item .= "<title size=\"" . $title_size . "\">" . $title_data . "</title>\n";
        $item .= "<content>" . $content_data . "</content>\n";
        $item .= " <pubdate>" . $pubdate_data . "</pubdate>\n";
        $item .= "</item>\n";
        return $item;
    }

PHP生成xml格式的数据直接加上 header(“Content-type: text/xml”);头就行了

<?php
 header("Content-type: text/xml");
$data_array = array(
    array(
    &#39;title&#39; => &#39;title1&#39;,
    &#39;content&#39; => &#39;content1&#39;,
        &#39;pubdate&#39; => &#39;2009-10-11&#39;,
    ),
    array(
    &#39;title&#39; => &#39;title2&#39;,
    &#39;content&#39; => &#39;content2&#39;,
    &#39;pubdate&#39; => &#39;2009-11-11&#39;,
    )
);
$title_size = 1;
$xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n";
$xml .= "<article>\n";
foreach ($data_array as $data) {
$xml .= create_item($data[&#39;title&#39;], $title_size, $data[&#39;content&#39;], $data[&#39;pubdate&#39;]);
}
$xml .= "</article>\n";
echo $xml;
//创建XML单项
function create_item($title_data, $title_size, $content_data, $pubdate_data)
{
    $item = "<item>\n";
    $item .= "<title size=\"" . $title_size . "\">" . $title_data . "</title>\n";
    $item .= "<content>" . $content_data . "</content>\n";
    $item .= " <pubdate>" . $pubdate_data . "</pubdate>\n";
    $item .= "</item>\n";
    return $item;
}
?>
