**Autobahn**|Java\n\nClient library providing [WAMP](http://wamp-proto.org/) on Java 8 ([Netty](https://netty.io/)) and Android, plus (secure) WebSocket for Android.\n\n[![Docker Hub](https://img.shields.io/badge/docker-ready-blue.svg)](https://hub.docker.com/r/crossbario/autobahn-java/)\n[![Travis](https://travis-ci.com/crossbario/autobahn-java.svg?branch=master)](https://travis-ci.com/crossbario/autobahn-java)\n[![Docs](https://javadoc.io/badge/io.crossbar.autobahn/autobahn-android.svg?label=docs)](https://javadoc.io/doc/io.crossbar.autobahn/autobahn-android)\n\n---\n\nAutobahn|Java is a subproject of the [Autobahn project](http://crossbar.io/autobahn/) and provides open-source client implementations for\n\n* **[The WebSocket Protocol](http://tools.ietf.org/html/rfc6455)**\n* **[The Web Application Messaging Protocol (WAMP)](http://wamp-proto.org/)**\n\nrunning on Android and Netty/Java8/JVM.\n\nThe WebSocket layer is using a callback based user API, and is specifically written for Android. Eg it does not run any network stuff on the main (UI) thread.\n\nThe WAMP layer is using Java 8 **[CompletableFuture](https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/CompletableFuture.html)** for WAMP actions (call, register, publish and subscribe) and the **[Observer pattern](https://en.wikipedia.org/wiki/Observer_pattern)** for WAMP session, subscription and registration lifecycle events.\n\nThe library is MIT licensed, maintained by the Crossbar.io Project, tested using the AutobahnTestsuite and published as a JAR to Maven and as a Docker toolchain image to Dockerhub.\n\n---\n\n\n## Download\n\nGrab via Maven:\n\n```xml\n\u003cdependency\u003e\n    \u003cgroupId\u003eio.crossbar.autobahn\u003c/groupId\u003e\n    \u003cartifactId\u003eautobahn-android\u003c/artifactId\u003e\n    \u003cversion\u003e21.7.1\u003c/version\u003e\n\u003c/dependency\u003e\n```\n\nGradle:\n```groovy\ndependencies {\n    implementation 'io.crossbar.autobahn:autobahn-android:21.7.1'\n}\n```\nFor non-android systems use artifactID `autobahn-java` or just\nDownload [the latest JAR](https://search.maven.org/remote_content?g=io.crossbar.autobahn\u0026a=autobahn-java\u0026v=LATEST)\n\n\n## Getting Started\n\nThe demo clients are easy to run, you only need `make` and `docker` installed to get things rolling. \u003c/br\u003e\n\n    $ make crossbar # Starts crossbar in a docker container\n    $ make python # Starts a python based WAMP components that provides calls for the Java demo client\n\nand finally\n\n    $ make java # Starts the java (Netty) based demo client that performs WAMP actions\n\n## Show me some code\n\nThe code in demo-gallery contains some examples on how to use the autobahn library, it also contains convenience methods to use. Below is a basic set of code examples showing all 4 WAMP actions.\n\n### Subscribe to a topic\n\n```java\npublic void demonstrateSubscribe(Session session, SessionDetails details) {\n    // Subscribe to topic to receive its events.\n    CompletableFuture\u003cSubscription\u003e subFuture = session.subscribe(\"com.myapp.hello\",\n            this::onEvent);\n    subFuture.whenComplete((subscription, throwable) -\u003e {\n        if (throwable == null) {\n            // We have successfully subscribed.\n            System.out.println(\"Subscribed to topic \" + subscription.topic);\n        } else {\n            // Something went bad.\n            throwable.printStackTrace();\n        }\n    });\n}\n\nprivate void onEvent(List\u003cObject\u003e args, Map\u003cString, Object\u003e kwargs, EventDetails details) {\n    System.out.println(String.format(\"Got event: %s\", args.get(0)));\n}\n```\nSince we are only accessing `args` in onEvent(), we could simplify it like:\n```java\nprivate void onEvent(List\u003cObject\u003e args) {\n    System.out.println(String.format(\"Got event: %s\", args.get(0)));\n}\n```\n### Publish to a topic\n\n```java\npublic void demonstratePublish(Session session, SessionDetails details) {\n    // Publish to a topic that takes a single arguments\n    List\u003cObject\u003e args = Arrays.asList(\"Hello World!\", 900, \"UNIQUE\");\n    CompletableFuture\u003cPublication\u003e pubFuture = session.publish(\"com.myapp.hello\", args);\n    pubFuture.thenAccept(publication -\u003e System.out.println(\"Published successfully\"));\n    // Shows we can separate out exception handling\n    pubFuture.exceptionally(throwable -\u003e {\n        throwable.printStackTrace();\n        return null;\n    });\n}\n```\nA simpler call would look like:\n```java\npublic void demonstratePublish(Session session, SessionDetails details) {\n    CompletableFuture\u003cPublication\u003e pubFuture = session.publish(\"com.myapp.hello\", \"Hi!\");\n    ...\n}\n```\n\n### Register a procedure\n\n```java\npublic void demonstrateRegister(Session session, SessionDetails details) {\n    // Register a procedure.\n    CompletableFuture\u003cRegistration\u003e regFuture = session.register(\"com.myapp.add2\", this::add2);\n    regFuture.thenAccept(registration -\u003e\n            System.out.println(\"Successfully registered procedure: \" + registration.procedure));\n}\n\nprivate CompletableFuture\u003cInvocationResult\u003e add2(\n        List\u003cObject\u003e args, Map\u003cString, Object\u003e kwargs, InvocationDetails details) {\n    int res = (int) args.get(0) + (int) args.get(1);\n    List\u003cObject\u003e arr = new ArrayList\u003c\u003e();\n    arr.add(res);\n    return CompletableFuture.completedFuture(new InvocationResult(arr));\n}\n```\nA very precise `add2` may look like:\n```java\nprivate List\u003cObject\u003e add2(List\u003cInteger\u003e args, InvocationDetails details) {\n    int res = args.get(0) + args.get(1);\n    return Arrays.asList(res, details.session.getID(), \"Java\");\n}\n```\n\n### Call a procedure\n\n```java\npublic void demonstrateCall(Session session, SessionDetails details) {\n    // Call a remote procedure.\n    CompletableFuture\u003cCallResult\u003e callFuture = session.call(\"com.myapp.add2\", 10, 20);\n    callFuture.thenAccept(callResult -\u003e\n            System.out.println(String.format(\"Call result: %s\", callResult.results.get(0))));\n}\n```\n\nCalling procedure with variable data type parameters\n\n```java\npublic void demonstrateCall(Session session, SessionDetails details) {\n    // Call a remote procedure.\n    byte[] var1 = new byte[20];\n    String var2 = \"A sample text\";\n    int var3 = 99;\n    List\u003cObject\u003e args = new ArrayList\u003c\u003e();\n    args.add(var1);\n    args.add(var2);\n    args.add(var3);\n    CompletableFuture\u003cCallResult\u003e callFuture = session.call(\"com.myapp.myproc\", args);\n    callFuture.thenAccept(callResult -\u003e\n            System.out.println(String.format(\"Call result: %s\", callResult.results.get(0))));\n}\n```\n\n### Connecting the dots\n\n```java\npublic void main() {\n    // Create a session object\n    Session session = new Session();\n    // Add all onJoin listeners\n    session.addOnJoinListener(this::demonstrateSubscribe);\n    session.addOnJoinListener(this::demonstratePublish);\n    session.addOnJoinListener(this::demonstrateCall);\n    session.addOnJoinListener(this::demonstrateRegister);\n\n    // finally, provide everything to a Client and connect\n    Client client = new Client(session, url, realm);\n    CompletableFuture\u003cExitInfo\u003e exitInfoCompletableFuture = client.connect();\n}\n```\n\n### Authentication\n\nAuthentication is simple, we just need to create an object of the desired authenticator and\npass that to the Client\n\n#### Ticket Auth\n```java\npublic void main() {\n    ...\n    IAuthenticator authenticator = new TicketAuth(authid, ticket);\n    Client client = new Client(session, url, realm, authenticator);\n    CompletableFuture\u003cExitInfo\u003e exitInfoCompletableFuture = client.connect();\n}\n```\n\n#### Challenge Response Auth\n```java\npublic void main() {\n    ...\n    IAuthenticator authenticator = new ChallengeResponseAuth(authid, secret);\n    Client client = new Client(session, url, realm, authenticator);\n    CompletableFuture\u003cExitInfo\u003e exitInfoCompletableFuture = client.connect();\n}\n```\n\n#### Cryptosign Auth\n```java\npublic void main() {\n    ...\n    IAuthenticator authenticator = new CryptosignAuth(authid, privkey, pubkey);\n    Client client = new Client(session, url, realm, authenticator);\n    CompletableFuture\u003cExitInfo\u003e exitInfoCompletableFuture = client.connect();\n}\n```\n\nYou can also provide a list of Authenticators\n\n```java\npublic void main() {\n    ...\n    List\u003cIAuthenticator\u003e authenticators = new ArrayList\u003c\u003e();\n    authenticators.add(new TicketAuth(authid, ticket));\n    authenticators.add(new CryptosignAuth(authid, privkey, pubkey));\n    Client client = new Client(session, url, realm, authenticators);\n    CompletableFuture\u003cExitInfo\u003e exitInfoCompletableFuture = client.connect();\n}\n```\n\nAutobahn also supports POJOs\n\nHere is how to call a remote procedure that returns a list of Person POJOs\n\n```java\n// Call a remote procedure that returns a Person with id 1\nCompletableFuture\u003cPerson\u003e callFuture = mSession.call(\"com.example.get_person\", 1);\ncallFuture.whenCompleteAsync((person, throwable) -\u003e {\n    if (throwable != null) {\n        // handle error\n    } else {\n        // success!\n        // do something with person\n    }\n}, mExecutor);\n```\n\n```java\n// call a remote procedure that returns a List\u003cPerson\u003e\nCompletableFuture\u003cList\u003cPerson\u003e\u003e callFuture = mSession.call(\n        // remote procedure to call\n        \"com.example.get_persons_by_department\",\n\n        // positional call arguments\n        new ArrayList\u003cObject\u003e() {List.of(\"department-7\")},\n\n        // call return type\n        new TypeReference\u003cList\u003cPerson\u003e\u003e() {}\n);\n\ncallFuture.whenCompleteAsync((persons, throwable) -\u003e {\n    if (throwable != null) {\n        // handle error\n    } else {\n        // success!\n        for (Person person: persons) {\n            // do something with person\n        }\n    }\n}, mExecutor);\n```\n\nAlso register a procedure that returns a Person\n\n```java\nprivate Person get_person() {\n    return new Person(\"john\", \"doe\", \"hr\");\n}\n\nprivate void main() {\n    CompletableFuture\u003cRegistration\u003e regFuture = session.register(\n            \"io.crossbar.example.get_person\", this::get_person);\n    regFuture.whenComplete((registration, throwable) -\u003e {\n        System.out.println(String.format(\n                \"Registered procedure %s\", registration.procedure));\n    });\n}\n```\n\n### WebSocket on Android\n\nEcho example\n\n```java\nWebSocketConnection connection = new WebSocketConnection();\nconnection.connect(\"wss://echo.websocket.org\", new WebSocketConnectionHandler() {\n    @Override\n    public void onConnect(ConnectionResponse response) {\n        System.out.println(\"Connected to server\");\n    }\n\n    @Override\n    public void onOpen() {\n        connection.sendMessage(\"Echo with Autobahn\");\n    }\n\n    @Override\n    public void onClose(int code, String reason) {\n        System.out.println(\"Connection closed\");\n    }\n\n    @Override\n    public void onMessage(String payload) {\n        System.out.println(\"Received message: \" + payload);\n        connection.sendMessage(payload);\n    }\n});\n```\n\n---\n\n### Building from source\n\nBuilding Autobahn is pretty simple\n\n#### Android build\n\nFor Android, we recommend to use Android Studio. Just import the project in\nAndroid Studio, it will tell you if there are any missing dependencies, install them\nand then just build the project from `Build \u003e Rebuild Project` and you will have the\naar artifact in `autobahn/build/outputs/aar/`\n\n#### Netty build\n\nTo produce a build for non-android systems make sure you have docker and make\ninstalled then just use run below command on the root directory of the project\n```shell\nmake build_autobahn\n```\nand that will output the jar file in `autobahn/build/libs/`.\n\n\n\n## Get in touch\n\nGet in touch by joining our [forum](https://crossbar.discourse.group/).\n\n---\n\n\n## Version 1\n\nVersion 1 of this library is still in the repo [here](https://github.com/crossbario/autobahn-java/tree/version-1), but is no longer maintained.\n\nVersion 1 only supported non-secure WebSocket on Android and only supported WAMP v1.\n\nBoth of these issues are fixed in the (current) version of Autobahn|Java.\n\n---\n","funding_links":[],"categories":["网络编程","Networking"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcrossbario%2Fautobahn-java","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcrossbario%2Fautobahn-java","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcrossbario%2Fautobahn-java/lists"}
