javascript axios json response code example

Example 1: axios get

const axios = require('axios');

// Make a request for a user with a given ID
axios.get('/user?ID=12345')
  .then(function (response) {
    // handle success
    console.log(response);
  })
  .catch(function (error) {
    // handle error
    console.log(error);
  })
  .then(function () {
    // always executed
  });

// Optionally the request above could also be done as
axios.get('/user', {
    params: {
      ID: 12345
    }
  })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  })
  .then(function () {
    // always executed
  });  

// Want to use async/await? Add the `async` keyword to your outer function/method.
async function getUser() {
  try {
    const response = await axios.get('/user?ID=12345');
    console.log(response);
  } catch (error) {
    console.error(error);
  }
}

Example 2: Using axios send a GET request to the address:

// Send a POST request
axios({
  method: 'post',
  url: '/user/12345',
  data: {
    firstName: 'Fred',
    lastName: 'Flintstone'
  }
});

Example 3: axios api post request

import qs from 'qs';
const data = { 'bar': 123 };
const options = {
  method: 'POST',
  headers: { 'content-type': 'application/x-www-form-urlencoded' },
  data: qs.stringify(data),
  url,
};
axios(options);

Example 4: axios response.json

const axios = require('axios');

const res = await axios.get('https://httpbin.org/get', { params: { answer: 42 } });

res.constructor.name; // 'Object', means `res` is a POJO

// `res.data` contains the parsed response body
res.data; // { args: { answer: 42 }, ... }
res.data instanceof Object; // true

Example 5: Using axios send a GET request to the address:

// GET request for remote image
axios({
  method: 'get',
  url: 'http://bit.ly/2mTM3nY',
  responseType: 'stream'
})
  .then(function(response) {
  response.data.pipe(fs.createWriteStream('ada_lovelace.jpg'))
});

Example 6: react axios post method

import React from 'react';
import axios from 'axios';

export default class PersonList extends React.Component {
  state = {
    name: '',
  }

  handleChange = event => {
    this.setState({ name: event.target.value });
  }

  handleSubmit = event => {
    event.preventDefault();

    const user = {
      name: this.state.name
    };

    axios.post(`https://jsonplaceholder.typicode.com/users`, { user })
      .then(res => {
        console.log(res);
        console.log(res.data);
      })
  }

  render() {

      <div>
        <form onSubmit={this.handleSubmit}>
          <label>
            Person Name:
