Example 6 with FileProps

use of io.vertx.core.file.FileProps in project georocket by georocket.

the class FileStore method getOne.

@Override
public void getOne(String path, Handler<AsyncResult<ChunkReadStream>> handler) {
    String absolutePath = Paths.get(root, path).toString();
    // check if chunk exists
    FileSystem fs = vertx.fileSystem();
    ObservableFuture<Boolean> observable = RxHelper.observableFuture();
    fs.exists(absolutePath, observable.toHandler());
    observable.flatMap(exists -> {
        if (!exists) {
            return Observable.error(new FileNotFoundException("Could not find chunk: " + path));
        }
        return Observable.just(exists);
    }).flatMap(exists -> {
        // get chunk's size
        ObservableFuture<FileProps> propsObservable = RxHelper.observableFuture();
        fs.props(absolutePath, propsObservable.toHandler());
        return propsObservable;
    }).map(props -> props.size()).flatMap(size -> {
        // open chunk
        ObservableFuture<AsyncFile> openObservable = RxHelper.observableFuture();
        OpenOptions openOptions = new OpenOptions().setCreate(false).setWrite(false);
        fs.open(absolutePath, openOptions, openObservable.toHandler());
        return openObservable.map(f -> new FileChunkReadStream(size, f));
    }).subscribe(readStream -> {
        // send chunk to peer
        handler.handle(Future.succeededFuture(readStream));
    }, err -> {
        handler.handle(Future.failedFuture(err));
    });
}

Example 7 with FileProps

use of io.vertx.core.file.FileProps in project vert.x by eclipse.

the class CoreExamples method exampleFuture1.

public void exampleFuture1(Vertx vertx, Handler<HttpServerRequest> requestHandler) {
    FileSystem fs = vertx.fileSystem();
    Future<FileProps> future = fs.props("/my_file.txt");
    future.onComplete((AsyncResult<FileProps> ar) -> {
        if (ar.succeeded()) {
            FileProps props = ar.result();
            System.out.println("File size = " + props.size());
        } else {
            System.out.println("Failure: " + ar.cause().getMessage());
        }
    });
}

use of io.vertx.core.file.FileProps in project vertx-examples by vert-x3.

the class Client method start.

@Override

    String filename = "upload.txt";
    FileSystem fs = vertx.fileSystem();
    WebClient client = WebClient.create(vertx);
    fs.props(filename, ares -> {
        FileProps props = ares.result();
        System.out.println("props is " + props);
        long size = props.size();
        HttpRequest<Buffer> req = client.put(8080, "localhost", "/");
        req.putHeader("content-length", "" + size);
        fs.open(filename, new OpenOptions(), ares2 -> {
            req.sendStream(ares2.result(), ar -> {
                if (ar.succeeded()) {
                    HttpResponse<Buffer> response = ar.result();
                    System.out.println("Got HTTP response with status " + response.statusCode());
                } else {
                    ar.cause().printStackTrace();
                }
