Question

我正在使用ASP.Net网络应用程序，我正在尝试在我的网站上查看谷歌地图，但无论我在哪里运行网站，我都会收到此错误：

此页面无法显示Google地图元素。提供商 Google API密钥无效或此网站无权使用它。错误代码：InvalidKeyOrUnauthorizedURLmapError

Answer 1

此错误通常发生，因为密钥参数是无效或此网站未被授权使用。在您的情况下，它很可能是您尝试重用其他资源中现有密钥的第二个原因。

基本上你有两个选择：

选项1

省略关键参数，因此请替换以下行：

 <script src="//maps.googleapis.com/maps/api/js?v=3&amp;sensor=false&amp;key=AIzaSyBs1MVxS8kIxL9BXrxYE0lfvDP-iF_cmeA&amp;callback=loadmap" defer></script>

带

<script src="//maps.googleapis.com/maps/api/js?v=3&amp;sensor=false&amp;callback=loadmap" defer></script>

选项2

Acquire a new key并用新的替换现有的。
