Custom attribute cannot be obtained in the config of interceptors

[zhuwenqi001]

Is your feature request related to a problem? Please describe.
For a request, it is necessary to record the status of the request. I want to add a loadkey parameter to each request, process it centrally in the Axios instance, and modify the value corresponding to the loadkey in the interceptors, but I can't get this custom parameter now. Previous versions of 0.17 were available

Describe the solution you'd like
