使用Node.js将文件上载到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.jssftp.put命令将文件传输到SFTP服务器。传输文件时出现以下错误。我可以成功建立连接。但是我无法向服务器读取/写入文件。我在下面附上了代码

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)
