How are exceptions handled in Axios?

Normal requests in Axios

When the request service returns normally in Axios, it falls into the. then() method.

axios.get('https://httpstat.us/200')
  .then(res => {
    console.log(res)
  })

The effect is as follows:

Axios will wrap the response result in the data property of the returned Response object, in addition to:

1. Config: Request configuration
2. Headers: Response header data (AxiosHeader object)
3. Request: Request an instance. The browser environment is the XMLHttpRequest object
4. Status: HTTP status code. This case is 200, indicating that the request has been successfully processed
5. StatusText: Text description of the status code

Abnormal requests in Axios

There are two types of abnormal requests in Axios: responsive abnormal requests and unresponsive abnormal requests.

Responsive exceptions

When the returned HTTP status code is a dog outside of 2xx, it will enter axios’. match() method.

403 response:

axios.get('https://httpstat.us/403')
  .catch(err => {
    console.log(err)
  })
