示例1: unTarGz
private async unTarGz(zipLocation: string, unzipLocation: string): Promise<void> {
return Promise.resolve(
fs
.createReadStream(zipLocation)
.pipe(zlib.createGunzip())
.pipe(tar.extract(unzipLocation))
);
}示例2: downloadJDK
https.get(url, (res) => {
if (res.statusCode === 302) {
// Redirected.
ended = true;
downloadJDK(res.headers['location'], destPath, cb);
return;
}
// Will be NaN if not given by server.
let contentLength = parseInt(res.headers['content-length']);
let progressBytes = 0;
let startTime = new Date().getTime();
function printStatus() {
let percent = "??";
if (!isNaN(contentLength)) {
percent = ((progressBytes/contentLength)*100).toFixed(0);
}
let lastPrint = new Date().getTime();
// bytes => kbytes
let dlSoFar = progressBytes >> 10;
let rate = dlSoFar / ((lastPrint - startTime) / 1000);
console.log(`[${percent}%] Received ${dlSoFar} KB [${rate.toFixed(2)} KB/s]`);
}
let interval = setInterval(function() {
printStatus();
}, 5000);
function end(err?: Error) {
if (!ended) {
ended = true;
clearInterval(interval);
cb(err);
}
}
res.pipe(gunzip()).pipe(tarFs.extract(destPath)).on('error', end).on('finish', end);
res.on('data', (d: Buffer) => {
progressBytes += d.length;
});
}).on('error', (err: Error) => {示例3: resolve
.on('response', response => {
if (response.statusCode === 200) {
stream

map: header => {
header.name = header.name.substring(header.name.indexOf('/'));
