javascript - 如何从 API 访问数据？

Question

我正在设置一个小脚本供我个人使用，通过测试 Nike API 来了解 Ajax 和 jQuery，以获取有关任何产品的信息。

我做了一个小循环来获取有关实际 API 的信息，但当我想传递秒对象时我陷入困境

function getSnkrs() {
    var test = $('.test');
    $.ajax({
        type: "GET",
        url: "https://api.nike.com/product_feed/threads/v2/?filter=marketplace%28FR%29&filter=language%28fr%29&filter=channelId%28010794e5-35fe-4e32-aaff-cd2c74f89d61%29&&filter=exclusiveAccess%28true%2Cfalse%29",
        async: false,

        success: function(data) {
            for (i = 0; i < 10; i++) {
                for (y = 0; y < 10; y++) {

                //<br><img src="'+ data._embedded.objects[i].publishedContent[i].nodes[i].properties[i].portraitURL[i].url +'"style="width: 20%; height=auto;><br>
                test.append('<br><a>'+    data.objects[i].publishedContent[y].marketplace   +'</a><br>');

            }
        }
    }
});

}

在控制台上我有这个:

jquery-1.9.1.js:7985 Uncaught TypeError: Cannot read property 'marketplace' of undefined
at Object.success (script.js:36)
at fire (jquery-1.9.1.js:1037)

如果有人可以帮助我，我想要“市场”元素，谢谢! :

    "prev": "",

我看到publisherContent不是一个数组？ (如果我错了，请纠正我)，它是一个 json 对象。尝试删除“y”循环:

for (var i = 0; i < data.objects.length; i++) {

//<br><img src="'+ data._embedded.objects[i].publishedContent[i].nodes[i].properties[i].portraitURL[i].url +'"style="width: 20%; height=auto;><br>
test.append('<br><a>'+ data.objects[i].publishedContent.marketplace   +'</a><br>');
}
