对于作业,我们需要制作一个恒温应用程序。我想在离子中做这个,但我现在正在努力使用提供的API。我们已经提供了一个API.js文件,其中包含一组函数,用于与我们从中获取数据的服务器进行通信。我试图通过提供程序自己创建这些函数但是因为服务器返回xml数据我到目前为止还没有成功。所以我想通过将它包含在我的项目中来使用给定的API.js,但我现在也在努力做到这一点。因此,我想了解如何将此外部API包含到我的离子项目中并使用已有的函数,或者如何使用返回的xml数据(在应用程序中显示它并将更改后的数据发回)。
由于这两个文件都很大,我在下面提供了一些代码段,并在pastebin链接中提供了完整的文件。
我们可以使用的get和put命令是day,time,currentTemperature,targetTemperature,dayTemperature,nightTemperature,weekProgramState和weekProgram。
提前多多感谢!!

我要做的是创建一个名为API.ts
的文件。在其中我将创建一个包含API.js
的属性和函数的API类,以纠正Typesctipt语法。
看起来好像写这个文件的人也想使用jquery
但是它没有导入,所以我也导入了它。我想你得到了这个文件,所以一定要把它放在src/assets
里面并更正我代码中的导入路径,以便得到匹配的文件名。
所以这就是我拥有的东西:
import * as $ from '.assets/jquery.js';
export class API {

Saturday: 'Saturday',
Sunday: 'Sunday'
};

现在,您想要使用API的任何离子组件,只需将其导入即可:
import { API } from './API'
然后在你的代码中使用它:
export class yourPage {
constructor(public api: API){}
yourFunction() {
this.api.setDefault();
}
}
