contentType	string		sets the `Content-Type` of the request. Eg: `application/json`
processData	boolean	true	whether format data to string
timeout	number		timeout by seconds
beforeSend	(io) => void		A function called before the request
success	(data, status, io) => void		A function called when the request successfully completes
error	({message, status, xhr}) => void	true	A function called when the request successfully error
complete	(data, status, io) => void		A function called when the request completes
jsonpCallback	string	callback	specify the jsonp request query name

methods

abort():void

abort current request

then(data): Promise

use data in promise

catch(e:{message, status, xhr}): Promise

catch error in promise

always(data|e)

always process in promise

static methods

ajaxSetUp(config)

interceptors

You can intercept requests or responses like axios.

// Add a request interceptor
io.interceptors.request.use((config) => {
  // Do something before request is sent
  return config;
});

// Add a response interceptor
io.interceptors.response.use(function (response) {
    // Do something with response data
    return response;
}, function (error) {
    // Do something with response error
    return Promise.reject(error);
});

And what's fun is you can turn a response into error

io.interceptors.response.use(function (response) {
    if(response.notLogin) {
        const error = new Error('not login');
        error.isSystemError = true;
        return Promise.reject(error);
    }
});

If you may need to remove an interceptor later you can.

var myInterceptor = io.interceptors.request.use(function () {/*...*/});
io.interceptors.request.eject(myInterceptor);
