var iconv = require('iconv-lite');

var oriText = '你';

var encodedBuff = iconv.encode(oriText, 'gbk');
console.log(encodedBuff);
// <Buffer c4 e3>

var decodedText = iconv.decode(encodedBuff, 'gbk');
console.log(decodedText);
// 你

var wrongText = iconv.decode(encodedBuff, 'utf8');
console.log(wrongText);
// "htmlcode">

var http = require('http');
var iconv = require('iconv-lite');

// 假设客户端采用post方法，编码为gbk
var server = http.createServer(function (req, res) {
  var chunks = [];
  
  req.on('data', function (chunk) {
    chunks.push(chunk)
  });

  req.on('end', function () {
    chunks = Buffer.concat(chunks);

    // 对二进制进行解码
    var body = iconv.decode(chunks, 'gbk');
    console.log(body);

    res.end('HELLO FROM SERVER');
  });

});

server.listen(3000);




对应的客户端代码如下：


var http = require('http');
var iconv = require('iconv-lite');

var charset = 'gbk';

// 对字符"你"进行编码
var reqBuff = iconv.encode('你', charset);

var options = {
  hostname: '127.0.0.1',
  port: '3000',
  path: '/',
  method: 'POST',
  headers: {
    'Content-Type': 'text/plain',
    'Content-Encoding': 'identity',
    'Charset': charset // 设置请求字符集编码
  }
};

var client = http.request(options, function(res) {
  res.pipe(process.stdout);
});

client.end(reqBuff);
