如何使用config选项测试axios

import axios from 'axios';

const instance = axios.create({
  baseURL: 'http://api.example.com',
  timeout: 5000,
  headers: {'Content-Type': 'application/json'}
});

instance.get('/api/users')
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });

instance.get('/api/users', {
  headers: {'Authorization': 'Bearer token'},
  params: {page: 1, limit: 10}
})
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });
