我只使用 html、css 和 js 制作了以下小部件。当您搜索我们数据库中存在的关键字（例如桃子或草莓）时，这本身就可以正常工作：

当我在 eclipse 中借助 fispace 的 add on 将其转换为小部件然后继续将其上传到 fiware lab 或 fispace 的 wirecloud 时，它显示错误缺少 api 密钥。所以我得到了谷歌的 api 密钥并像这样附加它：

<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBGrI_BKBCPZfOCskNEH5B5wiJhuV1yKeI"></script>

然而，我最终还是在线云内部得到了一张灰色的地图。 谁能帮我解决这个问题？谢谢你。

使用原始 HTML 文件时出现混合内容导致的错误。使用“ https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js ”和“ https://maps.googleapis.com/maps/api/js ”加载jquery和谷歌地图（考虑到shttps）解决了这个问题。至少当我搜索peach小部件时，它会显示一家Arsen Agro公司。
