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:
/** * 神馬搜尋資料結構化,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"); } /** * 神馬搜尋資料結構化,節點的具體內容 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; } ?>
