How can I get the status code from an http error i

问题:

This may seem stupid, but I'm trying to get the error data when a request fails in Axios.

axios.get('foo.com')
    .then((response) => {})
    .catch((error) => {
        console.log(error) //Logs a string: Error: Request failed with status code 404
    })

Instead of the string, is it possible to get an object with perhaps the status code and content? For example:

Object = {status: 404, reason: 'Not found', body: '404 Not found'}

回答1:

What you see is the string returned by the toString method of the error object. (error is not a string.)

If a response has been received from the server, the error object will contain the response property:

axios.get('/foo')
  .catch(function (error) {
    if (error.response) {
      console.log(error.response.data);
      console.log(error.response.status);
      console.log(error.response.headers);
    }
  });

As @Nick said, the results you see when you console.log a JavaScript Error object depend on the exact implementation of console.log, which varies and (imo) makes checking errors incredibly annoying.

If you'd like to see the full Error object and all the information it carries bypassing the toString() method, you could just use JSON.stringify:

axios.get('/foo')
  .catch(function (error) {
    console.log(JSON.stringify(error))
  });

I am using this interceptors to get the error response.

const HttpClient = axios.create({
  baseURL: env.baseUrl,
});

HttpClient.interceptors.response.use((response) => {
  return response;
}, (error) => {
  return Promise.resolve({ error });
});

This is a known bug, try to use "axios": "0.13.1"

I had the same problem so I ended up using "axios": "0.12.0". It works fine for me.
