cocosjs使用http请求

var httpHelper = {};
httpHelper.get = function(url, callback){
    var xhr = cc.loader.getXMLHttpRequest();
    console.log("Status: Send Get Request to ", url);
    xhr.open("GET", url, true);

    xhr.onreadystatechange = function () {
        if (xhr.readyState == 4 && (xhr.status >= 200 && xhr.status <= 207)) {
            var httpStatus = xhr.statusText;
            var response = xhr.responseText;
            console.log("Status: Got GET response! " + httpStatus);
            callback(true, xhr);
        }else{
            callback(false, xhr);
        }
    };
    xhr.send();
};

使用时

var url = "xxxxxx";
httpHelper.get(url,function(isSuccess, data){});
