laravel輸出xml資料,php輸出xml格式資料

2020-07-16 10:06:06
背景:

seo的同事要批次提交xml格式的資料到搜尋引擎,目前專案用laravel框架開發的,所以就有了這篇文章的誕生了。網上有不少關於php輸出xml格式的例子,小弟不才也搬過,只是在php檔案上面測試是沒問題的,把它搬到laravel框架裡面,就有有坑了,主要原因是header頭的問題。

laravel框架怎麼返回xml格式資料?

如果用header(「Content-type: text/xml」);

這樣的話是沒有效果的,會提示這樣的錯誤:

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的時候會自行用text/html方式返回資料,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資料格式例子:

 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['title'], $title_size, $data['content'], $data['pubdate']);
        }
        $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格式的資料直接加上 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 $xml;
//建立XML單項
function create_item($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;
}
?>
