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['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格式的数据直接加上 header(“Content-type: text/xml”);头就行了
"Content-type: text/xml"); | header(|
$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; | |
} | |
