使用适配器身份验证的Worklight推送通知不起作用

Question

我在Worklight测试应用中使用推送通知。我通过Worklight Adapter进行了身份验证。但是通过这种方式，我总是会收到来自PushAdapter的响应“找不到用户的订阅:: [sample_username]”

设备已通过身份验证：

我的测试Android设备订阅了通知。

我简单的AuthAdapter：

function onAuthRequired(headers, errorMessage) {
    errorMessage =  errorMessage ? errorMessage : null;
    return {
        authRequired: true,
        errorMessage: errorMessage
    };
}
function submitAuthentication(username, password) {
    var userIdentity = {
            userId: username,
            displayName: username,
            attributes: {
                foo: "bar"
            }
    };
    WL.Server.setActiveUser("AdapterAuthRealm", null);
    WL.Server.setActiveUser("AdapterAuthRealm", userIdentity);

    return {
        authRequired: false
    };
}

也许，我的推送通知服务代码对帮助很有用（Angular JS）：

    console.log(services.service('PushService'));
    if (WL.Client.Push){

        WL.Client.Push.onReadyToSubscribe = function(){

            WL.Client.Push.registerEventSourceCallback(
                "myPush",
                "PushAdapter",
                "PushEventSource",
                angular.element(document.body).injector().get('PushService').pushNotificationReceived);
        };

    }

    services.service('PushService', function($q) {

        var self = this;
        self.send = function(userID, text) {
            console.info("PushService:: send ",userID, text);
            var deferred = $q.defer();
            if (typeof WL !== 'undefined') {
                WL.Client.invokeProcedure({
                    adapter : 'PushAdapter',
                    procedure : 'submitNotification',
                    parameters : [userID, text]
                },{
                    onSuccess: function(response) {
                        deferred.resolve(response);
                        console.log("PushService:: push response: ",response);
                    },
                    onFailure: function(response) {
                        deferred.reject();
                    }
                });
            } else {
                deferred.reject();
                console.warn("WL is undefined");
            }
            return deferred.promise;
        };

        self.isSupported = function() {
            var isSupported = false;
            if (WL.Client.Push){
                console.log(WL.Client.Push);
                isSupported = WL.Client.Push.isPushSupported();
            }
            return isSupported;
        };
        self.isSubscribed = function() {
            var isSubscribed = false;
            if (WL.Client.Push){
                isSubscribed = WL.Client.Push.isSubscribed('myPush');
            }
            return isSubscribed;
        };
        self.subscribe = function() {
            var deferred = $q.defer();
            WL.Client.Push.subscribe("myPush", {
                onSuccess: function(response) { console.info("Push:: subscribe success"); deferred.resolve(response); },
                onFailure: function() { console.warn("Push:: subscribe failture"); deferred.reject(); }
            });
            return deferred.promise;
        };
        self.unsubscribe = function() {
            var deferred = $q.defer();
            WL.Client.Push.unsubscribe("myPush", {
                onSuccess: function(response) { console.info("Push:: unsubscribe success"); deferred.resolve(response); },
                onFailure: function() { console.warn("Push:: unsubscribe failture"); deferred.reject(); }
            });
            return deferred.promise;
        };
        self.pushNotificationReceived = function(props, payload) {
            console.info("pushNotificationReceived invoked:: ", JSON.stringify(props), JSON.stringify(payload));
        };

        return self;
    });

Answer 1

您的问题的一个可能方案是您尝试向用户发送会话已结束的推送。 例如，如果您有以下情形：

“conf \ server \ worklight.properties”中的“serverSessionTimeout = 3”（会话将在3分钟后结束）

和“apps \”“\ common \ js \ _ initOptions.js”：

// # How often heartbeat request will be sent to Worklight Server
heartBeatIntervalInSecs: -1,

移动应用程序不会发送心跳，因此在您的服务器超时（会话结束）之后就像您在服务器端注销了应用程序一样。所以，你取消订阅。这可能是推送通知失败的原因。

可能的解决方案是启用心跳或增加服务器端会话超时。

如果您还可以共享配置文件，那将会很有帮助：conf \ server \ worklight.properties和“apps \\ common \ js \ _ initsptions.js”以检查是否是这种情况。无论如何，如果是这种情况，第一次PUSH将在登录后持续3分钟然后您将开始得到错误。
