Requirements: judge the user's activity, and log out directly if the user is inactive for more than 30 minutes.

I wanted to record the time of the last request at the beginning, and use the time of the last request to judge the user's activity. It's a little limited.

Search the Internet, said to use the mouse movement state to detect whether the operation page. It's not bad at all, but it's a way. So...

// Detect user activity
function isActive() {
    var arr = ['index', 'login']
    var result = arr.some(function(item) {
        return window.location.href.indexOf(item) > 0
    })
    // result indicates that the current page may be index or registration page 
    // It's not the index page, it's not the registration page to detect the user's active state (mouse moving state)
    if (!result) {
        var lastTime = new Date().getTime();
        var currentTime = new Date().getTime();
        //Set timeout: 10 points
        var timeOut = 10 * 60 * 1000; 

        window.onload = function() {
            /* Detect mouse movement events */
            document.addEventListener('mousemove', function() {
                // Update last action time
                console.log('The mouse is moving')
                lastTime = new Date().getTime();
            })
        }

        /* Timer interval 1 minute, check whether the page has not been operated for a long time  */
        var quitTime = window.setInterval(testTime, 60000);

        // Timeout function
        function testTime() {
            //Update current time
            currentTime = new Date().getTime();
            console.log('currentTime', currentTime)
            //Judge whether it is timeout
            if (currentTime - lastTime > timeOut) {
                // console.log('timeout pull ')
                // Overtime operation
                axios.post(logoutUrl,params)
                .then(function (res) {
                  // Write time-out code, such as logout and so on
                })
                .catch(function (error) {
                  console.log(error);
                });
                // Clear timer
                window.clearInterval(quitTime)
            }
        }
    }
}

isActive()
