Question

我遇到了在JS Fiddle中显示地图的问题。就是这个例子：

https://developers.google.com/maps/documentation/javascript/examples/directions-waypoints

我通过粘贴到一个空白的html文档中使用了我的api密钥，但是当我将完整的JavaScript + HTML粘贴到JS Fiddle中时（所有这些都进入了HTML字段，不是理想的格式，但它应该仍然有效，对吧？）它给出了控制台错误“Google Maps API错误：RefererNotAllowedMapError。”

我尝试将https://maps.googleapis.com/maps/api/js粘贴到外部资源中，但这并未改变任何内容。

如果我确实添加了外部资源，我还需要

<script async defer
    src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
</script>

HTML中的

还是我可以摆脱它？

感谢您提供有关在JS Fiddle中使用此功能的任何提示！

Answer 1

您获得的error：Google Maps API error: RefererNotAllowedMapError.表示您没有该域的有效密钥。

RefererNotAllowedMapError错误

加载Google Maps JavaScript API的当前网址尚未添加到允许的引荐来源列表中。请在Google Developers Console上查看API密钥的引荐来源设置。

请参阅Google Developers Console中的API密钥。有关详细信息，请参阅安全使用API密钥的最佳做法。

最简单的修复（特别是对于您不喜欢jsfiddle.net的网站）是从网址中删除key=YOUR_API_KEY&（这不是有效密钥，而密钥不是必需，推荐）。
