将其转换为Base64第一

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, 

      }] 

     }); 

}
