angular http 客户端发布缺少响应

Question

I have a method in my angular 8 app like this:

this.http.post(url, body, options).subscribe(
  res => {
    console.log('here')
    console.log(res)
  }
)

If the backend is setup like this:

res.status(201).send({ msg: 'User created' });

The block inside the subscribe call gets executed.

However, if the backend is setup like this:

res.status(201).send('User created');

The block inside the subscribe call doesn't get executed (even though the backend processed the request).

Why is this so?

Answer 1

Angular http call expects object from backend while you are sending a string. Use response type in http options to get string in response

Answer 2

You are missing the parenthesis in the Subscribe.

. subscribe (res => {})
