为什么我的小部件不能在 Wirecloud 中工作？

Question

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：

当我借助 fispace 在 eclipse 中的附加组件将其转换为小部件，然后继续将其上传到 fiware lab 或 fispace 的 wirecloud 时，它显示缺少 api 键的错误。所以我得到了 google 的 api 键并像这样附加它：

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

然而我最终还是在线云中看到了一张灰色的地图。 谁能帮我解决这个问题？谢谢你。

Answer 1

我在使用原始 HTML 文件时因混合内容而出错。使用“https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" and "https://maps.googleapis.com/maps/api/js”加载 jquery 和 google 地图（考虑到 https 的 s）解决了这个问题。至少当我搜索 peach 时，小部件显示 Arsen Agro 公司。

为什么我的小部件不能在 Wirecloud 中工作？
