Interceptor -interceptors

What is the interceptor:

Axios interceptor is sent to the server request and response back experienced two pass

Request interceptor:

axios every start , when requested to perform logic here, you can make a pre-configured to send axios in this place, you can also make inspections before the hair, in the case of checks ok started thinking the server send request

 

1  // request interceptor 
2 axios.interceptors.request.use ( function (config) {
 . 3    // place business logic code 
. 4    return config;
 . 5 }, function (error) {
 . 6    // Axios occurred error handling 
. 7    return Promise .reject (error);
 . 8 });

 

 

 

In response interceptor:

axios completed with the server back to the client after the interaction to perform this logic, in this place can do some follow-up issues finishing, e.g. axios determines whether the request is successful, data filtering, or

 

// response blocker 
axios.interceptors.response.use ( function (Response) {
   // place business logic code 
  // Response is returned to the server data, the data obtained is consistent with Promise 
  return Response; 
}, function (error) {
   // Axios requests the server error handling occurs 
  return Promise.reject (error); 
});
