今天写demo时，调用http.request方法时遇到服务端报错BadRequestError: request aborted，点击进入报错的位置：

 然后根据我写请求里有content-length:

 发现是content-length乜有设置成和发送的消息内容的长度一致，把长度改成消息内容的长度就行了，或者注释掉也可以。

const postMsg = JSON.stringify({'msg':'I come from demo!'})
const options = {
    hostname: 'localhost',
    port: 3000,
    path: '/testReq',
    method: 'GET',
    headers: {
      'Content-Type': 'application/json',
      'Content-Length':Buffer.byteLength(postMsg),
    },
  };
const req = request(options,(res)=>{
    console.log(`STATUS: ${res.statusCode}`);
    console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
    res.setEncoding('utf8');
    res.on('data', (chunk) => {
        console.log(`BODY: ${chunk}`);
    });
    res.on('end', () => {
        console.log('No more data in response.');
    });
}).on('error',(stream)=>{
    console.log('连接到了=======',stream)
})
req.write(postMsg)
req.end()
