尝试通过JQuery的getJSON函数使用Google Places API

问题内容：

这可能是非常基本的，但是我正在尝试测试Google Places API。我正在阅读文档，并使用它们提供的一些示例。我正在尝试使用JQuery
getJSON函数，因为我已经能够成功地使用它与它异步异步地访问外部JSON文件，因此我认为这可能是获取Google
Places查询的JSON结果的一种好方法。这是我要使用的代码：

<body>
<div id="message"></div>
<script type="text/javascript">

    var requestURL = 'https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=false&key='my_google_places_key';
    $(document).ready(function () {
        $.getJSON(requestURL, function (data) {

            for (i = 0; i < data.results.length; i++) {
                myAddress[i] = data.results[i].formatted_address;
                document.getElementById("message").innerHTML += myAddress[i] + "<br>";
                console.log(myAddress[i]);
            }

        });
    });


</script>

</body>

根据文档，对查询的最终JSON响应应如下所示：

如果复制此JSON脚本并将其保存到文件中，则可以访问它，并且它在浏览器中显示以下结果：

529 Kent Street，Sydney NSW，Australia上层，海外客运大楼/ 5 Hickson Road，The Rocks
NSW，澳大利亚107 George Street，The Rocks NSW，澳大利亚483 George Street，Sydney
NSW，Australia

这意味着它有效。getJSON函数无法正确解析JSON脚本吗？

问题答案：

我会建议使用的商家信息库中的谷歌地图的JavaScript
API V3
。
