Je suis confronté à des problèmes dans l'envoi de réponse json à php que je reçois de twitter. J'avais passé beaucoup de temps mais je ne pouvais pas comprendre la source de l'erreur. La console ne génère aucune erreur mais mon code jquery pour POST json est en cours de blocage. J'ai validé json de lintjson & son valide. Quelqu'un peut-il dire gentiment ce qui pourrait causer des erreurs lors de l'envoi de JSON qui est reçu d'une source Web comme Twitter dans ce cas. Cela peut m'aider à affiner ma recherche de problèmes. Quelles sont les sources possibles d'erreurs lors de l'envoi d'un site Web à un serveur?

<?php
function searchResults($q) {
$host = "http://search.twitter.com/search.atom?q=" . urlencode($q) . "&rpp=100";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
//Raw xml
$result = curl_exec($ch);
curl_close($ch);
$xml = simplexml_load_string($result);
return json_encode($xml);
}
?>

N'est-ce pas une demande JSONP? Vous devriez utiliser 'jsonp' comme type de données –
@Pekka, lequel? Si vous demandez au json puis je l'ai copié depuis la console, la console remplace php par une instruction d'affectation js avec ceci. En fait, quand il a montré une erreur, c'est-à-dire «manquant». alors il l'a remplacé avec ceci en soulignant l'erreur. Je l'ai copié à partir de là. – XCeptable
@XCeptable ce n'est pas une réponse JSON, c'est JSONP, donc il contient '
