如何在ssh2sftp客户端中使用npmcli-progress

Question

我有一个使用npmsh2-sftp客户端从远程服务器下载文件的项目，所以我想在控制台中显示下载进度。下载文件很好，但我不知道如何在下载文件时使用cli progress来显示下载进度。

function getConnect(ip, name, pwd, remotepath, localpath) {
const sftp = new SftpClient();
sftp.connect({
host: ip,
port: 22,
username: name,
password: pwd
}).then(async () => {
const files = await sftp.list(remotepath, '.');
for (var j = 0; j < files.length; j++) {
var e =files[j];
await sftp.fastGet(remotepath + "/" + e.name, localpath + "\" + e.name);
}
}); 

Answer 1

我已经修改了，希望会更好

function getConnect(ip, name, pwd, remotepath, localpath) { 
const sftp = new SftpClient();
sftp.connect({
host: ip,
port: 22,
username: name,
password: pwd
}).then(async () => {
const files = await sftp.list(remotepath, '.');
for (var j = 0; j < files.length; j++) {
var e =files[j];
//=================================================
const Throttle = require('throttle');  
const progress = require('progress-stream'); 
const throttleStream = new Throttle(1); // create a "Throttle " instance that reads at 1 bps
const progressStream = progress({
length: e.size,
time: 100, // ms
});
progressStream.on('progress', (progress) => {
process.stdout.write("r" + " [" +e.name+"] downloaded ["+progress.percentage.toFixed(2)+"%]");
});
const outStream = createWriteStream(localpath);
throttleStream.pipe(progressStream).pipe(outStream);
try {
await sftp.get(remotepath + "/" + e.name, throttleStream,  { autoClose: false }); 
} catch {
console.log('sftp error', e);
} finally {
await sftp.end();
}
}
}
}

我遵循了@Abbas Agus Basari的建议，喜欢：

await sftp.fastGet(secondPath + "/" + e.name, localPath + "\" + e.name,  {
step: step=> {
const percent = Math.floor((step / e.size) * 100);
process.stdout.write("r" + "【"+e.name+"】downloaded【"+percent+'%】');
}
});
