通話を録音する

着信に応答し、録音するように設定する方法を示すコード・スニペット。録音し、通話に接続します。通話が完了すると eventUrl で指定した record NCCOのアクションは、ダウンロード用の録画URLを含むウェブフックを受け取ります。

We can use the アプリケーション plugin for Gradle to simplify the running of our application. Update your build.gradle with the following:

apply plugin: 'application'
mainClassName = project.hasProperty('main') ? project.getProperty('main') : ''

Run the following gradle command to execute your application, replacing com.vonage.quickstart.kt.voice with the package containing RecordCall:

gradle run -Pmain=com.vonage.quickstart.kt.voice.RecordCall

/*
 * Route to answer and connect incoming calls with recording.
 */
Route answerRoute = (req, res) -> {
    String recordingUrl = String.format("%s://%s/webhooks/recordings", req.scheme(), req.host());

    RecordAction record = RecordAction.builder().eventUrl(recordingUrl).build();

    ConnectAction connect = ConnectAction.builder(PhoneEndpoint.builder(VOICE_TO_NUMBER).build())
            .from(VONAGE_VIRTUAL_NUMBER).build();

    res.type("application/json");

    return new Ncco(record, connect).toJson();
};

/*
 * Route which prints out the recording URL it is given to stdout.
 */
Route recordingRoute = (req, res) -> {
    System.out.println(EventWebhook.fromJson(req.body()).getRecordingUrl());

    res.status(204);
    return "";
};

Spark.port(3000);
Spark.get("/webhooks/answer", answerRoute);
