CRUD nodejs/express服务器:app.put req.body为空 [英] CRUD nodejs/express server: app.put req.body is empty

问题描述

我刚刚用基本的Crud操作编写了一个超简单的nodejs后端.但是，在put语句上，我没有收到请求的正文:

I just wrote a ultrasimple nodejs backend with basic crud operations. However on the put statement i don't receive the body of my request:

 app.put('/note-update/:id', function (req, res) {
  var noteId = req.params.id;
  console.log(req.body)
  db.collection('notes').update({
    _id: noteId
  }, req.body, (err, result) => {
    res.send(
      (err === null) ? {
        msg: req.body
      } : {
        msg: err
      }
    );
  });
});

这是我使用ajax执行的呼叫:

Here is the call i execute with ajax:

var note = {
    _id: "599e660cbc845b4e2952715f",
    name: "Genauer Detailbeschrieb",
    note: "Ey-10"
}

$.ajax({
    type: 'PUT',
    url: '/note-update/599e660cbc845b4e2952715f',
    dataType: 'JSON',
    contentType: "application/json; charset=utf-8",
    data: JSON.stringify(note)
})

如您所见，我有一个console.log(req.body)，我得到的只是{}

as you can see i have a console.log(req.body) and all i get is {}

推荐答案

您在使用bodyparser吗?

Are you using the bodyparser?

app.use(bodyParser.json());

如果不起作用，请为您的节点设置显示更多代码.

Plz show more code for your node setup if it doesn't work.
