How to set header and options in axios?

I use Axios to perform an HTTP post like this:

import axios from 'axios'
params = {'HTTP_CONTENT_LANGUAGE': self.language}
headers = {'header1': value}
axios.post(url, params, headers)

Is this correct? Or should I do:

axios.post(url, params: params, headers: headers)

There are several ways to do this:

  • For a single request:

    let config = {
      headers: {
        header1: value,
      }
    }
    
    let data = {
      'HTTP_CONTENT_LANGUAGE': self.language
    }
    
    axios.post(URL, data, config).then(...)
    
  • For setting default global config:

    axios.defaults.headers.post['header1'] = 'value' // for POST requests
    axios.defaults.headers.common['header1'] = 'value' // for all requests
    
  • For setting as default on axios instance:

    let instance = axios.create({
      headers: {
        post: {        // can be common or any other method
          header1: 'value1'
        }
      }
    })
    
    //- or after instance has been created
    instance.defaults.headers.post['header1'] = 'value'
    
    //- or before a request is made
    // using Interceptors
    instance.interceptors.request.use(config => {
      config.headers.post['header1'] = 'value';
      return config;
    });
