socket.io-java-client cookies / custom headers [英] socket.io-java-client cookies / custom headers

问题描述

我为网站做了一个移动应用程序，他们使用Socket.io和Websocket通信。

I'm doing a mobile app for a website and they use Socket.io and Websocket to comunicate.

我使用socket.io-java-client在Android上连接到Socket.io服务器，问题是，我不知道如何设置自定义标头/ cookie与它。

I'm using socket.io-java-client on Android to connect to the Socket.io server, the problem is, i don't know how to set custom headers / cookies with it.

这里是如何代码看起来像：

here is how the code looks like:

    public void runIO(){
        try {
            SocketIO socket = new SocketIO("http://192.168.1.60:1337");
            socket.connect(new IOCallback() {
                @Override
                public void onMessage(JSONObject json, IOAcknowledge ack) {
                    try {
                        System.out.println("Server said:" + json.toString(2));
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void onMessage(String data, IOAcknowledge ack) {
                    System.out.println("Server said: " + data);
                }

                @Override
                public void onError(SocketIOException socketIOException) {
                    System.out.println("an Error occured");
                    socketIOException.printStackTrace();
                }

                @Override
                public void onDisconnect() {
                    System.out.println("Connection terminated.");
                }

                @Override
                public void onConnect() {
                    System.out.println("Connection established");
                }

                @Override
                public void on(String event, IOAcknowledge ack, Object... args) {
                    System.out.println("Server triggered event '" + event + "'");
                }
            });

            // This line is cached until the connection is establisched.
            socket.send("Hello Server!");
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

推荐答案

事实上有一些简单的函数可以在连接之前用来设置头文件：

In fact there are simple functions that can be used to set headers before connection:

addHeader（String key，String value）和 setHeaders（Properties headers）

您也可以使用 SocketIO ，Properties headers）（而不是 SocketIO（final String url），我正在使用）：

You can also use SocketIO(final String url, Properties headers) (instead of SocketIO(final String url) that i was using):

// Haeader Properties initiation
    private Properties headers = new Properties();

，然后例如设置cookie：

and then for exemple to set cookies:

headers.setProperty("Cookie","key=data;key2=data2");

最后连接替换

this.socket = new SocketIO(val);

由

this.socket = new SocketIO(val,this.headers);
