Apache Camel:使用Twilio发送文本消息

[英]Apache Camel: Send Text Message with Twilio

我正在尝试使用camel-twilio组件通过Apache Camel发送文本消息。 由于我从未使用过Twilio API(既未使用本机也未使用过Apache Camel),因此我不确定参数是否正确。 这是我写的方法:

/**
 * Sends a text message to the given recipient's number (parameter to)
 * 
 * @param username:
 *            Twilio username (email)
 * @param password:
 *            Twilio password (in plain text)
 * @param accountSid:
 *            Twilio account sid (from the dashboard)
 * @param from:
 *            registered phone number (starting with country prefix +XX)
 * @param to:
 *            the recipient's phone number (starting with country prefix +XX)
 * @param message:
 *            the message to be sent (plain text)
 * @throws Exception
 */
public static void sendTextMessage(String username, String password, String accountSid, String from, String to,
        String message) throws Exception {
    String route = String.format("twilio:message/creator?username=%s&password=%s&accountSid=%s&from=%s&to=%s",
            username, password, accountSid, from, to);
    CamelContext context = new DefaultCamelContext();
    context.addRoutes(new RouteBuilder() {
        @Override
        public void configure() throws Exception {
            from("direct:message").to(route);
        }
    });
    context.start();
    ProducerTemplate producer = context.createProducerTemplate();
    producer.sendBody("direct:message", message);
    context.stop();
}

最重要的一行是方法的创建,即路线的创建。 当我根据JavaDoc使用参数运行此方法时,出现以下错误:

Caused by: org.apache.camel.RuntimeCamelException: Missing properties for creator, need one or more from [pathAccountSid, mediaUrl, messagingServiceSid, body]

所以我想添加参数messagingServiceSid ,再次提供我的accountSid

String route = String.format("twilio:message/creator?username=%s&password=%s&accountSid=%s&from=%s&to=%s&messagingServiceSid=%s",
            username, password, accountSid, from, to, accountSid);

现在,我收到此错误消息:

Caused by: java.lang.IllegalArgumentException: No matching method for message/creator, with arguments [messagingServiceSid, from, to]

我究竟做错了什么?

编辑:这些是我的Maven依赖项:

<dependencies>
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-core</artifactId>
        <version>2.20.1</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-twilio</artifactId>
        <version>2.20.1</version>
    </dependency>
</dependencies>

编辑2:这是该方法的修改和工作版本:

/**
 * Sends a text message to the given recipient's number (parameter to)
 * 
 * @param accountSid:
 *            Twilio account sid (from the dashboard)
 * @param authToken:
 *            Twilio auth token (from the dashboard)
 * @param from:
 *            registered phone number (starting with country prefix +XX)
 * @param to:
 *            the recipient's phone number (starting with country prefix +XX)
 * @param message:
 *            the message to be sent (plain text)
 * @throws Exception
 */
public static void sendTextMessage(String accountSid, String authToken, String from, String to, String message)
        throws Exception {
    CamelContext context = new DefaultCamelContext();
    TwilioComponent twilio = context.getComponent("twilio", TwilioComponent.class);
    twilio.getConfiguration().setUsername(accountSid);
    twilio.getConfiguration().setPassword(authToken);
    context.addRoutes(new RouteBuilder() {
        @Override
        public void configure() throws Exception {
            from("direct:message")
                    .setHeader("CamelTwilioTo", constant(new PhoneNumber(to)))
                    .setHeader("CamelTwilioFrom", constant(new PhoneNumber(from)))
                    .setHeader("CamelTwilioBody", constant(message))
                    .to("twilio://message/creator");

        }
    });
    context.start();
    ProducerTemplate producer = context.createProducerTemplate();
    producer.sendBody("direct:message", message);
    context.stop();
}

我必须说,要有效地使用camel-twilio,您需要对Twilio Java API有很好的了解。 在您的情况下,让我们在这里熟悉MessageCreator API:
https://www.twilio.com/docs/libraries/reference/twilio-java/7.17.0/com/twilio/rest/api/v2010/account/MessageCreator.html

话虽如此,首先,由于username (即accountSid )和password应该在camel-twilio组件中共享,因此让我们在该组件上进行设置:

TwilioComponent twilio = context.getComponent("twilio", TwilioComponent.class);
twilio.getConfiguration().setUsername(username);
twilio.getConfiguration().setPassword(password);

(请注意,大多数时候twilio用户名和accoundSid指的是同一件事,因此您只能使用其中之一。)

设置用户名/密码后,让我们使用MessageCreator 你可以用最简单的构造是MessageCreator(PhoneNumber to, PhoneNumber from, String body) ,但因为tofrom必须PhoneNumber情况下,很容易将它们传递到端点骆驼邮件头而不是将它们嵌入到端点的URI作为端点参数。 (注意:可以在带有CamelTwilio前缀的消息头中提供任何camel-twilio端点选项。)

看起来类似于以下内容:

    public void configure() throws Exception {
        from("direct:message")
            .setHeader("CamelTwilioTo", constant(new PhoneNumber(to)))
            .setHeader("CamelTwilioFrom", constant(new PhoneNumber(from)))
            .setHeader("CamelTwilioBody", constant(message))
            .to("twilio://message/creator");
    }

注意,此时,端点URI可以像twilio://message/creator一样简单。

现在您应该可以将文本发送到Twilio。

仅供参考,在Spring Boot中有一个camel-twilio的有效示例:
