本机传输插件 - 在 ionic2 中安装后不可用 [英] Native transfer plugin - not available after install in ionic2

问题描述

我分两步在我的 ionic 2 应用程序中安装了本机 TRANSFER 插件:
1. 离子插件添加cordova-plugin-file-transfer
2. npm install --save @ionic-native/transfer

I have installed native TRANSFER plugin in my ionic 2 app in 2 steps:
1. ionic plugin add cordova-plugin-file-transfer
2. npm install --save @ionic-native/transfer

之后，我在 home.ts 页面中导入了插件.
从 '@ionic-native/transfer' 导入 { Transfer }

After that i imported the plugin in my home.ts page.
Import { Transfer } from '@ionic-native/transfer'

我尝试使用插件上传文件var ft = new Transfer();

I tried to use the plugin to upload a file var ft = new Transfer();

但我不能使用 ft var，因为 Transfer 插件看起来不可用.如果我编写 ft.upload () 我会收到如下错误:Property 'upload' doesn't exist on type 'Transfer'.

But i can't use ft var, because Transfer plugin look like it's not avalable. If i write ft.upload () i receive an error like: Property 'upload' does not exist on type 'Transfer'.

我的技术:
科尔多瓦 CLI:6.4.0
离子框架版本:2.3.0
Ionic CLI 版本:2.2.1
离子应用程序库版本:2.2.0
离子应用脚本版本:1.1.4

My technologies:
Cordova CLI: 6.4.0
Ionic Framework Version: 2.3.0
Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
Ionic App Scripts Version: 1.1.4

在我的应用程序的以前版本中，使用 Ionic Framework Version: 2.0.0-rc.5/Ionic App Scripts Version: 1.0.0 一切正常.

In the previous version of my app when using Ionic Framework Version: 2.0.0-rc.5 /Ionic App Scripts Version: 1.0.0 all worked just fine.

有人对此有任何解决方案吗?提前致谢.

Does anyone has any solution for this? Thanks in advance.

推荐答案

在Ionic Native 3.1.0版本中，你必须像提供者一样使用插件.

In the 3.1.0 version of Ionic Native, you have to use the plugin like a provider.

1. 在app.module.ts中导入并设置为provider

1. Import it in app.module.ts and set as provider

 import {Transfer} from '@ionic-native/transfer'

 @ngModule({
   //...
   providers:[
       Transfer,
       ..]

在你需要使用的地方注入组件/提供者.

Inject in the component/provider where you need to use it.

constructor(private fileTransfer:Transfer){}

使用 fileTransfer 对象.
