RxWebSocket

招聘：我司正在招聘Android架构师职位，如有兴趣，请点击[email protected] 邮箱，期待你的到来！

RxWebSocket是一个基于okhttp和RxJava(RxJava1和RxJava2都有)封装的WebSocket客户端,此库的核心特点是 除了手动关闭WebSocket(就是RxJava取消订阅),WebSocket在异常关闭的时候(onFailure,发生异常,如WebSocketException等等),会自动重连,永不断连.其次,对WebSocket做的缓存处理,同一个URL,共享一个WebSocket.

RxJava2版本点我(RxJava2和RxJava1调用方式一样)

how to use

添加依赖:

在项目module下gradle加入:

    implementation 'com.dhh:websocket:2.1.2'

init

        //init config 在使用RxWebSocket之前设置即可，推荐在application里初始化
        Config config = new Config.Builder()
                .setShowLog(true)           //show  log
                .setClient(yourClient)   //if you want to set your okhttpClient
                .setShowLog(true, "your logTag")
                .setReconnectInterval(2, TimeUnit.SECONDS)  //set reconnect interval
                .setSSLSocketFactory(yourSSlSocketFactory, yourX509TrustManager) // wss support
                .build();
        RxWebSocket.setConfig(config);

WSS support,其实就是设置okhttp的SSL,请参照okhttp的设置，请参照上面Config配置

心跳检测：需要设置自己的okhttpClient，在上面的Config里设置心跳间隔：

        Config config = new Config.Builder()
                .setClient(new OkHttpClient.Builder()
                        .pingInterval(3, TimeUnit.SECONDS) // 设置心跳间隔，这个是3秒检测一次
                        .build())  //if you want to set your okhttpClient
                .build();

open WebSocket:和RxJava调用一样，回调请使用项目里提供的 WebSocketSubscriber，WebSocketSubscriber是一个没有抽象方法的抽象类，根据业务需求，重写你想使用的回调

        RxWebSocket.get("url")
                .subscribe(new WebSocketSubscriber() {
                    @Override
                    protected void onMessage(@NonNull String text) {

                    }
                });

        RxWebSocket.get("your url")
                //RxLifecycle : https://github.com/dhhAndroid/RxLifecycle
                .compose(RxLifecycle.with(this).<WebSocketInfo>bindToLifecycle())
                .subscribe(new WebSocketSubscriber() {
                    @Override
                    public void onOpen(@NonNull WebSocket webSocket) {
                        Log.d("MainActivity", "onOpen1:");
                    }

                    @Override
                    public void onMessage(@NonNull String text) {
                        Log.d("MainActivity", "返回数据:" + text);
                    }

                    @Override
                    public void onMessage(@NonNull ByteString byteString) {

                    }

                    @Override
                    protected void onReconnect() {
                        Log.d("MainActivity", "重连:");
                    }

                    @Override
                    protected void onClose() {
                        Log.d("MainActivity", "onClose:");
                    }
                });

如果你想将String类型的text解析成具体的实体类,请使用 WebSocketSubscriber2

        /**
         *
         *如果你想将String类型的text解析成具体的实体类，比如{@link List<String>},
         * 请使用 {@link  WebSocketSubscriber2}，仅需要将泛型传入即可
         */
        RxWebSocket.get("your url")
                .compose(RxLifecycle.with(this).<WebSocketInfo>bindToLifecycle())
                .subscribe(new WebSocketSubscriber2<List<String>>() {
                    @Override
                    protected void onMessage(List<String> strings) {

                    }
                });

发送消息

        //用WebSocket的引用直接发
        mWebSocket.send("hello word");
        //url 对应的WebSocket 必须打开,否则报错
        RxWebSocket.send(url, "hello");
        RxWebSocket.send(url, ByteString.EMPTY);
        //异步发送,若WebSocket已经打开,直接发送,若没有打开,打开一个WebSocket发送完数据,直接关闭.
        RxWebSocket.asyncSend(url, "hello");
        RxWebSocket.asyncSend(url, ByteString.EMPTY);

注销

RxJava的注销方式,就可以取消订阅.

    Subscription subscription = RxWebSocket.get("ws://sdfs").subscribe();
    //注销
    if(subscription!=null&&!subscription.isUnsubscribed()) {
        subscription.unsubscribe();
    }

更优雅的注销处理方式,请看我的另一个项目: RxLife,优雅地处理RxJava注销问题,和Activity生命周期绑定.
