我正在尝试将视频上传到s3，并有一个预先签名的PUT网址。以下是执行此操作的代码。

import {Component} from '@angular/core';
import {NavController} from 'ionic-angular';
import {MediaCapture} from 'ionic-native';
import {Http} from '@angular/http';
import { Transfer } from 'ionic-native';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})

export class HomePage {

    public base64Image: string;

    constructor(private navController: NavController, public http: Http) {
        this.base64Image = "https://placehold.it/150x150";
    }

    public takeVideo() {
        MediaCapture.captureVideo({limit:2}).then(function(videoData){
            var link = "https://mysamplebucket.s3.amazonaws.com/non-tp/esx.mov?AWSAccessKeyId=TEMP_KEYY&Expires=1482290587&Signature=JUIHHI%2FcnLkqSVg%3D&x-amz-security-token=FQoDYXDGRfTXk6hma0Rxew6yraAX%2FlYGaQmYLwkvsuuB3%2F%2FtPvGDVs3dIQG0Ty3MeMjn0p%%26djt5xhAMk73pndJbZP0tCYYlvPvlUAyL8x7O%%2B3AwEa%%2B9b43yarIuPLCvujmKLTDyi%%3D%3Di";

            var options: any;

            options = {
             fileKey: 'file',
             fileName: 'esx.mov',
             httpMethod: 'PUT',
             chunkedMode: false,
             mimeType: 'video/quicktime',
             encodeURI: false,
             headers: {
                'Content-Type': 'video/quicktime'
              }
            };

            var …
