压缩：

从index.html压缩成index.html.gz

const zlib = require('zlib');

const gzip = zlib.createGzip();
const fs = require('fs');
const inp = fs.createReadStream('index.html');
const out = fs.createWriteStream('index.html.gz');

inp.pipe(gzip)
.on('error', () => {
// 处理错误
})
.pipe(out)
.on('error', () => {
// 处理错误
});


解压：

从index.html.gz解压为index.html

const zlib = require('zlib');

const gzip = zlib.createGzip();
const fs = require('fs');
const inp = fs.createReadStream('index.html.gz');
const out = fs.createWriteStream('index.html');

inp.pipe(gzip)
.on('error', () => {
// 处理错误
})
.pipe(out)
.on('error', () => {
// 处理错误
});

node线上项目连接mysql出现 504 Gateway Time-Out

var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '123456',
port: '3306',
database: 'test'
});


一定别忘了加端口号 ↓

port: '3306',
