angular - ionic:添加到app.module.ts时FileUploadOptions抛出错误

我试图在aws s3上上传图片，因为我使用@ionic native/file transfer，但是当我试图添加fileuploadoptions时，我得到了错误。filetransfer和filetransferobject不会出现错误。对于AWS S3，我需要FileUploadOptions.params。
注意：我已经调查了node_modules/@ionic native/file transfer一些fileuploadoptions代码有注释。这是个问题吗？有人知道其他稳定的文件传输版本吗？我现在疯了
我已经用这些命令安装了脚本

$ ionic cordova plugin add cordova-plugin-file-transfer
$ npm install --save @ionic-native/file-transfer

然后我更新了app.module.ts：

import { FileTransfer, FileUploadOptions, FileTransferObject } from '@ionic-native/file-transfer';

在app.module.ts的provider数组中：

providers: [
        StatusBar,
        FileUploadOptions,
        FileTransfer,
        FileTransferObject,
        File,
        Camera,
        SplashScreen,
        {
            provide: ErrorHandler,
            useClass: IonicErrorHandler
        },
        {
            provide: AuthHttp,
            useFactory: getAuthHttp,
            deps: [Http]
        },
        DataServiceProvider,
        LocationServiceProvider,
        Geolocation,
        JwtHelper,
        AuthServiceProvider
    ]

当我在提供程序数组中添加fileuploadoptions时，会出现以下错误：
typescript错误'fileuploadoptions'只引用一个类型，但是
在这里被用作一个值。

最佳答案

您只需要在FileTransfer数组中包含providers：

providers: [
    StatusBar,
    // FileUploadOptions,
    // FileTransferObject,
    FileTransfer, // <--- This one!
    File,
    Camera,
    SplashScreen,
    {
        provide: ErrorHandler,
        useClass: IonicErrorHandler
    },
    {
        provide: AuthHttp,
        useFactory: getAuthHttp,
        deps: [Http]
    },
    DataServiceProvider,
    LocationServiceProvider,
    Geolocation,
    JwtHelper,
    AuthServiceProvider
]

FileUploadOptions和FileTransferObject不是提供程序，而是与插件交互时使用的类/接口。
