Question

我正在尝试将表单数据发布到服务器（节点）但是当我将控制台放到后端的数据时它没有到达那里它说undefined.Data已经从客户端发送但未在服务器中到达。我想我标题错了，任何人都可以建议帮助。我的，

    var headers = new Headers();
    headers.append('Content-Type', 'application/x-www-form-urlencoded')
    this.http.post(this.header1+'login', JSON.stringify(form), { headers: headers })

我的服务器，

exports.login = function( req, res ) {
 console.log("Params:"+req.body.email);
  //console.log('email:'+params.email);
  var query = 'select * from profile where email = ? and password = ?'; 
 connection.query(query,[req.body.email,req.body.password],function(error,result,rows,fields){
    if(!!error){console.log(error)
      console.log('fail');
    }else{
      console.log(result);
      res.send(result);
    }
  // }

  });}

我的路线（快递）

 router.post('/login', admin.login);

你需要

Observable

让this.http.post(this.header1+'login', JSON.stringify(form), { headers: headers }) .subscribe(response => console.log(response.json()); this.http.post(this.header1+'login', JSON.stringify(form), { headers: headers }) .toPromise();发送请求。

数据已从客户端发送，但未在服务器angular2和nodejs中到达
