首先将其转换为Base64

setVideoToUpload(video){
    let platform = (Platform.OS === 'ios') ? 'ios' : 'android'
    let originalHeight = video.height
    let originalWidth = video.width
    let path = video.uri;
    var filename = Date.now().toString();



        MovToMp4.convertMovToMp4(path, filename + ".mp4", function (data) {
            //here you can upload the video...

            let videoToUpload = [{
                data: data,
                width: originalWidth ,
                height: originalHeight,
                imageOrVideo: 'video',
                type: '.mp4',
                platform: 'ios',
                duration: video.duration,
                uri: this.props.route.lastCaptured.path,

            }]

        });

}
