Is there a unified jump tool at the front end?

Development environment:
Front-end react
back-end java

it turns out that it is to see what the code is in the return value to decide whether to jump to the login interface. The jump is only set on a few interfaces.
if you are not logged in, the backend APIs will return 401.
whether there are any tools that can be set uniformly. For all interfaces, jump to the login page if the request interface returns a status of 401?

react I don't know if there is, but there should be. The axios, used by vue can use the returned http status code to make related jumps

does every interface call XMLHttpRequest directly?
it is recommended that XMLHttpRequest be encapsulated as an ajax method and provided to the calling interface. In this ajax method, the status code of the returned body json is judged and redirected

add a response interceptor with axios, for example: 

axios.interceptors.response.use(response => {
//
    if (response.status && response.status == 200 && response.data.status == 'error') { 
        return;
    }
        return response;
    }, err => {
    if (err && err.response) {
        switch (err.response.status) {
            case 400:
                err.message = ''
                break;
            case 401:
                err.message = ''
                break;
            case 403:
                err.message = ''
                break;
            case 404:
                err.message = ','
                break;
            case 405:
                err.message = ''
                break;
            case 408:
                err.message = ''
                break;
            case 500:
                err.message = ''
                break;
            case 501:
                err.message = ''
                break;
            case 502:
                err.message = ''
                break;
            case 503:
                err.message = ''
                break;
            case 504:
                err.message = ''
                break;
            case 505:
                err.message = 'http'
                break;
            default:
                err.message = '' + err.response.status
        }
    }
    else {
        err.message = ""
    }
    return Promise.resolve(err.response)
})

want to see the details of axios: https://www.kancloud.cn/yunye.

you can encapsulate the request method yourself, and then set the intercept. 

// ajax
$(document).ajaxComplete((event, xhr, settings) => {
    if (xhr.status === 200) {
        if (settings.dataType === 'json' && xhr.responseJSON !== void 0) {
            let result = xhr.responseJSON;
            if (2001 === result.code) {
                // session
                global.location.href = "/main-login.html";
            }
        }
    } else if (xhr.status === 401) {} else {
         global.location.href = "/main-login.html";
    }
});
export default function(options) {
    const defaultOptions = {
        dataType: 'json',
        cache: true,
        jsonp: 'callback'
    };
    options.data = processRequest(options);
    //url
    options.url = options.url;

    options.headers = {
        "Accept": "application/json",
        "Content-Type": "application/json"
    };

    return $.ajax({...defaultOptions, ...options }).then(processResponse);
};
// 
function processRequest(r) {
    const str = r.data || {};
    if ('get' == r.method) {
        if ($.isEmptyObject(str) || null == str) {
            return {
                t: new Date().getTime()
            };
        } else {
            return {
                //
                params: JSON.stringify(str),
                t: new Date().getTime()
            };
        }
    } else {
        return JSON.stringify(str);
    }
}

// 
function processResponse(r) {
    let str = {};
    if (r.rows) {
        str = r;
        str.code = 0;
        str.list = r.rows;
        delete str.rows;
    } else {
        if (!r.error) {
            if (0 <= r.code) {
                str = r;
            } else {
                str.code = 0;
                str.data = r;
            }
        } else {
            str.code = -1;
            str.message = r.message || r.error;
        }
    }
    return str;
}
