我试图在AWS s3上上传图像，因为我使用的是@ionic-native/file-transfer，但是当我试图添加FileUploadOptions时，我会得到错误。FileTransfer和FileTransferObject不会出现错误。我需要FileUploadOptions.params为AWS s3。

注意:我已经研究过node_/@离子型本机/文件传输-一些FileUploadOptions代码被注释了。这有问题吗？有没有人知道其他稳定的文件传输版本。我现在疯了

我使用以下命令安装了脚本

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

比我更新我的app.module.ts：

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

在app.module.ts的提供者数组中：

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，我会得到以下错误：

类型记录错误“FileUploadOptions”仅指类型，但在此处用作值。C:/xampp/htdocs/ionic/tellworld-mobile/src/app/app.module.ts StatusBar，FileUploadOptions，FileTransfer，

只需在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 
]
