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:
/** * 神马搜索数据结构化,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"); } /** * 神马搜索数据结构化,节点的具体内容 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( '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 $xml; //创建XML单项 function create_item($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; } ?>
