OptionalafterThis method will be invoked after the server responded to a request. The implementor may substitute a custom response instead.
OptionalbeforeThis method will be invoked before a request is sent to the server. The implementor may alter the input arguments (e.g. query parameters in BeforeInterceptorData.target).
An interceptor can intercept and manipulate requests (and their responses) before or after they have been sent to the server.
