JavaScript 简单的实现 sleep功能 .

function start(){
    // console.log("Request handle 'start' was called.");

    function sleep(milliSeconds){
        var startTime = new Date().getTime();
        while(new Date().getTime() < startTime + milliSeconds);
    }

    sleep(10000);
    console.log("Request handle 'start' was called.");
    return "Hello Start.";
}


function upload(){
    console.log("Request handle 'upload' was called.");
    return "Hello upload.";
}

exports.start = start;
exports.upload = upload;

中的:

    function sleep(milliSeconds){
        var startTime = new Date().getTime();
        while(new Date().getTime() < startTime + milliSeconds);
    }

    sleep(10000);
