PHP - REST API - HTTP头 - 错误处理 [英] PHP - REST API - http headers - error handling
问题描述
我试图用XML声明的过程是否成功与否一起返回一个HTTP标头。
本都出现,而发展我的API是工作的罚款,我正在测试呼叫从同一个服务器的API,并与XML获得相关的头状态code一起。然而,当我再次测试这一点,但调用其他服务器的API和我遇到的一个问题。
如果响应是200然后我得到的响应XML。如果有错误,我收到了标题状态code OK,但得到没有错误XML。我身边有机智的错误信息功能发挥,并注意到,如果我注释掉头($ status_header);
错误XML发送。任何人都可以提供一些线索,为什么这可能发生?
静态函数errorResponse($状态= 400,$ =身体''){ $ STATUS_MESSAGE = APIResponse的getStatus :: codeMessage派生($状态);
$ status_header =HTTP / 1.1。 $状态。 ''。 $ STATUS_MESSAGE; //设置HTTP状态
头($ status_header); 如果($体==''){
//如果没有传递创建消息
$身体=''; 开关($状态)
{
案例401:
$身体='必须被授权查看该页。';
打破;
案例404:
$身体='请求的URL。 $ _ SERVER ['REQUEST_URI']。 ' 没找到。';
打破;
案例500:
$身体='服务器遇到一个错误处理您的请求。;
打破;
案例501:
$身体='请求的方法未实现。;
打破;
} } $ response_xml ='< XML版本=1.0编码=UTF-8&GT?;
<错误>
<日期和GT;' 。日期(D,D M Y H:我:秒,时间())。 '< /日期和GT;
<状态>' 。 $状态。 - 。 $ STATUS_MESSAGE。 '< /状态>
<&消息GT;<![CDATA [。 $身体。 ']]>< /消息>
< /错误>'; 返回$ response_xml;
出口;}
现在我已经整理这一点,这是我的包含类卷曲功能的错误,无关此类。
I am trying to return a HTTP header together with XML stating whether a process has been successful or not.
This all appeared to be working fine whilst developing my API, I was making test calls to the API from the same server and getting the relevant header status code together with the XML. However, when I test this again but calling the API from other server and am encountering a problem.
If the response is 200 then I get the response XML. If there is an error, I receive the header status code OK but get no error XML. I have played around wit the the error messaging function and noticed that if I comment out header($status_header);
the error XML is sent. Can anyone shed some light as to why this might be happening?
static function errorResponse($status = 400, $body = '') {
$status_message = APIResponse::getStatusCodeMessage($status);
$status_header = 'HTTP/1.1 ' . $status . ' ' . $status_message;
// set the HTTP status
header($status_header);
if($body == '') {
// create the message if none is passed
$body = '';
switch($status)
{
case 401:
$body = 'You must be authorized to view this page.';
break;
case 404:
$body = 'The requested URL ' . $_SERVER['REQUEST_URI'] . ' was not found.';
break;
case 500:
$body = 'The server encountered an error processing your request.';
break;
case 501:
$body = 'The requested method is not implemented.';
break;
}
}
$response_xml = '<?xml version="1.0" encoding="utf-8"?>
<error>
<date>' . date("D, d M Y H:i:s", time()) . '</date>
<status>' . $status . ' - ' . $status_message . '</status>
<message><![CDATA[' . $body . ']]></message>
</error>';
return $response_xml;
exit;
}
I've now sorted this, it was an error with my class containing CURL functions, nothing to do with this class.
