How to add a response from the server to a state with an object in react-CodePudding

I have user state with object:

{
'login': 'somelogin',
 'pass': 'somepass'
}

Using this data, I send a request and receive a response in the form of several keys

const res  = await post("/api/login", user);

Response comes an object:

{
'xsrf': 'qweqweqwe', 
'session': 'asdasdasd'
}

How do i merge the current state with the response so that in the user state it would be like this:

{
'login': 'somelogin', 
'pass': 'somepass', 
'xsrf': 'qweqweqwe', 
'session': 'asdasdasd'
}

I can't think of what to write in the state setUser

something like: setUser(user res.data)

I don't know much about javascript and can't figure it out

CodePudding user response：

You can merge multi object with below expression.

  const a = {'a': 1};
  const b = {'b': 2};

  const c = {...a, ...b};  // {'a': 1, 'b': 2}

In your case:

  const user = {
    'login': 'somelogin',
    'pass': 'somepass'
  };
  const response = {
    'xsrf': 'qweqweqwe', 
    'session': 'asdasdasd'
  };

  const result = {...user, ...response};
