问题描述
我正在使用以下代码:
function GetTwitterAvatar($username){
$xml = simplexml_load_file("http://twitter.com/users/".$username.".xml");
$imgurl = $xml->profile_image_url;
return $imgurl;
}
function GetTwitterAPILimit($username, $password){
$xml = simplexml_load_file("http://$username:$password@twitter.com/account/rate_limit_status.xml");
$left = $xml->{"remaining-hits"};
$total = $xml->{"hourly-limit"};
return $left."/".$total;
}
并在流无法连接时收到这些错误:
and getting these errors when the stream cannot connect:
Warning: simplexml_load_file(http://twitter.com/users/****.xml) [function.simplexml-load-file]: failed to open stream: HTTP request failed! HTTP/1.0 503 Service Unavailable
Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "http://twitter.com/users/****.xml"
Warning: simplexml_load_file(http://...@twitter.com/account/rate_limit_status.xml) [function.simplexml-load-file]: failed to open stream: HTTP request failed! HTTP/1.0 503 Service Unavailable
Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "http://***:***@twitter.com/account/rate_limit_status.xml"
我该如何处理这些错误，以便显示用户友好的消息而不是上面显示的消息?
How can I handle these errors so I can display a user friendly message instead of what is shown above?
推荐答案
我在 php 文档.
所以代码是:
libxml_use_internal_errors(true);
$sxe = simplexml_load_string("<?xml version='1.0'><broken><xml></broken>");
if (false === $sxe) {
echo "Failed loading XML
";
foreach(libxml_get_errors() as $error) {
echo " ", $error->message;
}
}
以及我们/我预期的输出:
加载 XML 失败
Blank needed here
parsing XML declaration: '?>' expected
Opening and ending tag mismatch: xml line 1 and broken
Premature end of data in tag broken line 1
