laravel框架和php怎么返回xml格式數(shù)據(jù)？

背景：

seo的同事要批量提交xml格式的數(shù)據(jù)到搜索引擎，目前項(xiàng)目用laravel框架開發(fā)的，所以就有了這篇文章的誕生了。網(wǎng)上有不少關(guān)于php輸出xml格式的例子，小弟不才也搬過，只是在php文件上面測(cè)試是沒問題的，把它搬到laravel框架里面，就有有坑了，主要原因是header頭的問題。

laravel框架怎么返回xml格式數(shù)據(jù)？

如果用header(“Content-type: text/xml”);

這樣的話是沒有效果的，會(huì)提示這樣的錯(cuò)誤：

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框架在輸出xml的時(shí)候會(huì)自行用text/html方式返回?cái)?shù)據(jù)，解決辦法：

需要return response($xml,200)->header(“Content-type”,“text/xml”);這樣的方式才能改變header頭

laravel返回xml數(shù)據(jù)格式例子：

/**
  * 神馬搜索數(shù)據(jù)結(jié)構(gòu)化，written:yangxingyi Data:2018-10-25 11:15
  */
 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['title'], $title_size, $data['content'], $data['pubdate']);
        }
        $xml .= "</article>\n";
        #echo $xml;
        return response($xml,200)->header("Content-type","text/xml");
    }
 /**
  * 神馬搜索數(shù)據(jù)結(jié)構(gòu)化，節(jié)點(diǎn)的具體內(nèi)容 written:yangxingyi
  */
    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格式的數(shù)據(jù)直接加上 header(“Content-type: text/xml”);頭就行了

<?php
 header("Content-type: text/xml");
$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) {
$xml .= create_item($data['title'], $title_size, $data['content'], $data['pubdate']);
}
$xml .= "</article>\n";
echo $xml;
//創(chuàng)建XML單項(xiàng)
function create_item($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;
}
?>
