此文件的内容类型因Accept
标头或format
查询参数而异。看来您至少可以检索 XML 或 JSON。
您获得的默认值file_get_contents()
将是 JSON,因为它不包含请求标头,但来自浏览器的默认值将是 XML,因为浏览器通常在其请求标头Accept
中包含 XML mime 类型。Accept
要获取 JSON:
$url = 'http://sc2ranks.com/api/psearch/am/MxGPezz/1t/division/Felanis%20Sierra?appKey=sentinelgaming.net';
// &format=json is not strictly necessary,
// but it will give you fewer surprises
$json = file_get_contents($url.'&format=json');
$records = json_decode($json);
echo $records[0]->achievement_points, "\n";
要获取 XML:
$sxe = simplexml_load_file($url.'&format=xml');
echo (string) $sxe->record->{'achievement-points'}, "\n";
要使用该$sxe
对象,请参阅此 SimpleXML 备忘单。
format
您可以设置Accept
标题,而不是使用参数。您还可以添加一些抽象来获取 url,以便您也可以检索内容类型和编码。请参见下面的示例。
function get_url($url, $context=null) {
$response = file_get_contents($url, false, $context);
$ctypeheaders = preg_grep('/^Content-Type:\s/i', $http_response_header);
$ctype = NULL;
if ($ctypeheaders) {
$ctype = end($ctypeheaders);
$ctype = end(explode(':', $ctype, 2));
$ctype = explode(';', $ctype, 2);
$charset = isset($ctype[1]) ? $ctype[1] : '';
if ($charset && preg_match('/charset\s*=\s*([^\s]+)/i', $charset, $matches)) {
$charset = $matches[1];
}
$ctype[1] = $charset;
$ctype = array_map('trim', $ctype);
}
return array($response, $ctype);
}
然后你可以get_url()
像这样使用:
// With no accept header, just see what we get:
list($content, $contenttype) = get_url($url);
list($type, $encoding) = $contenttype;
// $type will be 'application/xml' or 'application/json'
// $encoding is very handy to know too
// Or we can specify an accept header:
$opt_accept_xml = stream_context_create(array(
'http' => array(
'header' => "Accept: application/xml\r\n"
)
));
list($content, $contenttype) = get_url($url, $opt_accept_xml);
