'react js send object to node js

I send the object to the backend(Node js) when API call. but I check objects using console log. I checked using POSTMAN. When I checked POSTMAN, I worked very well. But I try to pass an object in the frontend (react js) it is shown as undefined.

  getnotification(){
  const userdetails={
  userid:"1235",
  username:this.state.name
  }
  axios.get('http://localhost:4000/notification/',userdetails)
  .then((res)=>{ this.setState((cur) => ({ ...cur, notification: res.data.reverse() }));

  })
}

If you want to [POST], you need to use axios.post(url, body).

Following are the possible method signatures for axios.

axios.request(config)

axios.get(url[, config])

axios.delete(url[, config])

axios.head(url[, config])

axios.options(url[, config])

axios.post(url[, data[, config]])

axios.put(url[, data[, config]])

axios.patch(url[, data[, config]])

You ar missing the "{}". You can do something like this:

const userDetails = {
      userid:'1235',
      username:this.state.name
    }
axios.get('/user', {
    params: userDetails
  })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  })
  .then(function () {
    // always executed
  });

You can use the async / await syntax instead of the callback function, but it's not supported by all browsers. And you can add error handling to the async function in simple ways.

async getNotification() {
        const userDetails = {
            userid: "1235",
            username: this.state.name
        }

        try {
            const res = axios.get('http://localhost:4000/notification/', userDetails)
            this.setState((cur) => ({...cur, notification: res.data.reverse()}));
        } catch (error) {
            console.log(error);
        }
    }
