检查是否作为“离子服务"运行在程序中使用条件 [英] Check if running as "ionic serve" to use a conditional in the program

问题描述

有没有办法在程序中检测 ionic serve CLI 正在运行(然后不在真实设备上)并将其用作条件.

Is there a way to detect that ionic serve CLI is running (and then not on a real device) in the program and use it as a conditional.

我的问题:我有一个 Cordova 插件，可以将答案发送回 Cordova.

My issue: I have a Cordova plugin that sends back an answer to Cordova.

当我使用 Ripple 时，它​​提供了选择要发送回 JavaScript 的回调值(以模拟插件结果).

When I was using Ripple, it offered to chose the value of the callback to be sent back to JavaScript (to emulate the plugin result).

我注意到，当我在浏览器中运行时，Ionic2 并没有这样做.因此，为了简化我的开发并使其能够在浏览器上进行测试(而不是不断构建到真实设备)，如果 ionic serve CLI 是，我希望能够检查程序跑步.换句话说:检查它是在真实设备还是普通浏览器上运行.

I notice that Ionic2 does not do that when I run in a browser. So to ease my dev and make it possible to test it on a browser (and not build to the real device constantly), I would like to be able to check in the program if the ionic serve CLI is running. In other words: Check if it is running on a real device or a regular browser.

如果它在浏览器上运行，那么我会使用提示来要求用户为 Cordova 插件结果输入一个虚拟值，而不是真正的 Cordova 插件.

If it runs on the browser then I'd used a prompt to ask the user to enter a dummy value for the Cordova plugin result instead of the real Cordova plugin.

推荐答案

查看平台 文档:

检查它是在真实设备还是普通浏览器上运行.

Check if it is running on a real device or a regular browser.

您可以使用平台信息来执行此操作:

You can use the platform information in order to do so:

Platform Name   Description
android         on a device running Android.
cordova         on a device running Cordova.
core            on a desktop device.
ios             on a device running iOS.
ipad            on an iPad device.
iphone          on an iPhone device.
mobile          on a mobile device.
mobileweb       in a browser on a mobile device.
phablet         on a phablet device.
tablet          on a tablet device.
windows         on a device running Windows.

所以你可以这样做:

import { Platform } from 'ionic-angular';

@Component({...})
export MyPage {
  constructor(public platform: Platform) {

    if (this.platform.is('mobileweb') || this.platform.is('core')) {
      // This will only print when running on desktop
      console.log("I'm a regular browser!");
    }
  }
}
