Echec de getJSON lorsque le paramètre est int

J'ai une fonction jQuery qui récupère une réponse JSON à partir d'une page PHP. L'un des paramètres passés à getJSON() est une année. Si je passe un int (2008) Firebug signale une erreur 404 et l'appel getJSON échoue, mais si je passe une chaîne (x2008) Firebug signale un code 200 et déclenche le callback. Dans les deux cas, la page PHP renvoie une réponse identique - elle détecte automatiquement x2008 comme invalide et utilise la valeur par défaut de 2010 à la place - et Firebug montre qu'elle a reçu la réponse. Il échoue si je passe l'int en tant que chaîne, aussi ('2008').Echec de getJSON lorsque le paramètre est int

est ici l'appel getJSON:


$mr.getJSON(controller, {call: 'getWeekList', year: '2008'}, function(data) 
{ 
    var newList = '';   
    $mr.each(data, function(index, value) 
    { 
     newList += '' + value + ''; 
    }); 
    newList += ''; 

    $mr("#selectWeekList").html(newList); 
});

Firebug signale une réponse correcte, même si elle dit qu'il y avait un 404:

La réponse semble identique quand ça marche et quand ça ne marche pas, et évidemment ce n'était pas vraiment un 404 depuis qu'il a eu la réponse, donc je ne peux pas comprendre pourquoi Firebug pense qu'il y a un 404 et échoue.

En fait, il semble que ce soit un problème de serveur ou de navigateur. Si je charge le fichier PHP directement, je peux obtenir un 200 dans Chrome, mais un 404 dans Firefox et IE. Vous pouvez voir ici: http://willingcook.com/wp-content/plugins/manage-recipes/controllers/ajax-controller.php?call=getWeekList&year=2007 - 404 http://willingcook.com/ wp-content/plugins/gérer-recettes/contrôleurs/ajax-controller.php? call = getWeekList & année = x2007 - 200 –

Avez-vous essayé de définir le code d'état des têtes lorsque vous construisez JSON dans le page php?

header($_SERVER["SERVER_PROTOCOL"]." 200 OK");

Cela a fonctionné, merci :) Je me demande pourquoi le serveur ne renverrait pas le bon code tout seul, cependant. –

Si vous retournez JSON, le type de contenu ne doit pas être text/html, il devrait être application/json

Merci epascarello. J'ai corrigé cela, mais cela n'a pas semblé affecter le problème du tout. –
