如何将对象从客户端传递到服务器Nodejs

var obj = { name: "John", age: 30 };
var json = JSON.stringify(obj);

var http = require('http');

var options = {
  hostname: '服务器地址',
  port: 80,
  path: '/api',
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Content-Length': json.length
  }
};

var req = http.request(options, function(res) {
  res.setEncoding('utf8');
  res.on('data', function(chunk) {
    console.log('服务器响应：' + chunk);
  });
});

req.on('error', function(e) {
  console.log('请求出错：' + e.message);
});

req.write(json);
req.end();

var http = require('http');

var server = http.createServer(function(req, res) {
  var body = '';
  req.on('data', function(chunk) {
    body += chunk;
  });

  req.on('end', function() {
    var obj = JSON.parse(body);
    console.log('接收到客户端对象：', obj);
    // 对象处理逻辑
    res.end('服务器已接收到对象');
  });
});

server.listen(80, function() {
  console.log('服务器已启动');
});
