token存入前端的请求头中,后端获取【秒杀项目】

token存入前端的请求头中

function set_login_status() {
    var $A = $(".user-name");
    if (!$A) return false;

    $.ajax({
        type: "GET",
        url: SERVER_PATH + "/user/status",
        xhrFields: {withCredentials: true},
        beforeSend: function(xhr) {
            xhr.setRequestHeader('Authorization', 'Bearer ' + window.sessionStorage.getItem("token"));
        },
        success: function (result) {
            if (result.status == "0" && result.data) {
                $A.text(result.data.nickname);
                $("#user-info").show();
            } else {
                $("#user-info").hide();
            }
        }
    });    
}

function logout() {
    $.ajax({
        type: "GET",
        url: SERVER_PATH + "/user/status",
        xhrFields: {withCredentials: true},
        beforeSend: function(xhr) {
            xhr.setRequestHeader('Authorization', 'Bearer ' + window.sessionStorage.getItem("token"));
        },
        success: function (result) {
            if (result.status) {
                alertBox(result.data.message);
                return false;
            }
            alertBox("已经注销！", function(){
                window.location.href = "./login.html"
            });
        }
    });    
}

        String token = request.getHeader("Authorization");
        User user = null;
        if (StringUtils.isNotEmpty(token)) {
            user = (User) redisTemplate.opsForValue().get(token);
        }

        return new ResponseModel(user);
