使用 Node.js 将文件上传到 SFTP 服务器时出现故障代码 4

Question

我已经编写了代码来建立 SFTP 连接并使用 Node.js

sftp.put

命令将文件传输到 SFTP 服务器。我在传输文件时收到以下错误。我可以成功建立连接。但我无法向服务器读取/写入文件。我附上了下面的代码

代码

let sftp = new client();

  let filename = "sound.mp3";
  const filePath = path.join(__dirname, '../audio', filename)
  
   const putConfig = {
    flags: 'w', // w - write and a - append
    encoding: null, // use null for binary files
    mode: 0o666, // mode to use for created file (rwx)
    autoClose: true // automatically close the write stream when finished
  };
  
  sftp.connect({
      host: 'host',
      port: '22',
      username: 'xxxx',
      password: 'xxx'
    }).then(() => {
      return sftp.put(filePath, '/', putConfig)
    }).then(data => {
      console.log(data, 'the data info');
    }).catch(err => {
      console.log(err, 'catch error');
    });

错误

Answer 1

SftpClient.put

的第二个参数是目标远程文件的路径，而不仅仅是目标远程文件夹的路径。

所以应该是这样的：

return sftp.put(filePath, '/' + filename, putConfig)
