Question

我正在使用文件传输插件将文件上传到服务器。在这里我也想发送其他参数。

下面是代码。

public uploadVideo(path:any,name:any,filetype:any){
  const fileTransfer: FileTransferObject = this.transfer.create();
  let options1: FileUploadOptions = {
    fileKey: 'video_upload_file',
    fileName: name,
    headers: {},
    mimeType: 'mp4/webm',
    params: {"storage":filetype},
    chunkedMode: false
  };

  fileTransfer.upload(path, 'http://forcast.co.in:8888/api/v1/uploadVideo', options1)
 .then((data) => {
  const alert = this.alertCtrl.create({
    title: 'Success',
    subTitle: 'data saved successfully',
    buttons: ['OK']
  });
  alert.present();
 }, (err) => {
  const alert = this.alertCtrl.create({
    title: 'Error',
    subTitle:JSON.stringify(err),
    buttons: ['OK']
  });
  alert.present();
 })
}

以上代码将文件上传到服务器，但是 params：{“ storage”：filetype}， 在这里，我在类型为options的参数中传递了一个键值对 FileUploadOptions 。

如何在服务器端访问或显示此键值。我在服务器端使用节点js。下面是服务器端代码。

public uploadVideo(req: any, res: any) {
    if (!req.files) {
      console.log('No files uploaded');
      return res.status(400).send('No files were uploaded.');
    }

    let document = req.files.video_upload_file;
    console.log(document.name);
    console.log(document,"Checking for all params")
    let docfiles = req.files;
    console.log(docfiles,"all parameters in uploadvideo")
    let docfiletype = req.files.params;
    console.log(docfiletype,"parameters in uploadvideo")
    const uploadDir = '/home/forcast/forcast2443/media-repo/';
    if (!fs.existsSync(uploadDir)) {
      fs.mkdirSync(uploadDir);
    }

    document.mv(uploadDir + document.name, err => {
      if (!err) {
        console.log('Upload successful!');
        res.status(200).send({
          message: 'Upload successful!'
        });
      } else {
        console.log('Error saving file: ' + err);
        return res.status(500).send(err);
      }
    });
  }

如何显示在选项内传递的参数值？如您所见，甚至我正在显示console.log（req.files），但这不包含params的值。

请帮助我
