php - 使用 Camel 从 ActiveMQ 发布 HTTP

Question

我们使用 Camel 路线将值从队列发布到 http 端点。

我已经使用 Camel 的 http component 成功设置了路线, 但我无法获取要发布的 jms 消息正文。

比如我的路由是这样设置的:

<route errorHandlerRef="dlc" autoStartup="true" id="route2" xmlns:ns2="http://camel.apache.org/schema/web" xmlns="http://camel.apache.org/schema/spring">
    <from uri="activemq:test"/>
    <setHeader headerName="CamelHttpMethod">
            <constant>POST</constant>
        </setHeader>
    <to uri="http://localhost/tim/camel/" id="to2"/>
</route>

这导致了一个 POST，但是消息正文没有出现在我的 POST 字符串中(作为来自 $_SERVER 的 print_r):

Array
(
    [instance] => local
    [HTTP_JMSDELIVERYMODE] => 1
    [HTTP_JMSDESTINATION] => queue://test
    [HTTP_JMSEXPIRATION] => 0
    [HTTP_JMSTYPE] => 
    [HTTP_JMSTIMESTAMP] => 1291468702773
    [HTTP_JMSPRIORITY] => 0
    [HTTP_JMSCORRELATIONID] => 
    [HTTP_JMSMESSAGEID] => ID:new-host-3.home-62248-1291465669089-4:3:1:1:4
    [HTTP_JMSREDELIVERED] => false
    [HTTP_USER_AGENT] => Jakarta Commons-HttpClient/3.1
    [HTTP_HOST] => localhost
    [HTTP_COOKIE] => $Version=0; PHPSESSID=32aa692c71e1003f2e540c1b80c3b363; $Path=/
    [CONTENT_LENGTH] => 44
    [CONTENT_TYPE] => text/html
    [PATH] => /usr/bin:/bin:/usr/sbin:/sbin
    [SERVER_SIGNATURE] => <address>Apache/2.0.59 (Unix) PHP/5.2.6 DAV/2 mod_ssl/2.0.59 OpenSSL/0.9.7l Server at localhost Port 80</address>

    [SERVER_SOFTWARE] => Apache/2.0.59 (Unix) PHP/5.2.6 DAV/2 mod_ssl/2.0.59 OpenSSL/0.9.7l
    [SERVER_NAME] => localhost
    [SERVER_ADDR] => 127.0.0.1
    [SERVER_PORT] => 80
    [REMOTE_ADDR] => 127.0.0.1
    [DOCUMENT_ROOT] => /wufoo/trunk/
    [SERVER_ADMIN] => you@example.com
    [SCRIPT_FILENAME] => /wufoo/trunk/tim/camel/index.php
    [REMOTE_PORT] => 62877
    [GATEWAY_INTERFACE] => CGI/1.1
    [SERVER_PROTOCOL] => HTTP/1.1
    [REQUEST_METHOD] => POST
    [QUERY_STRING] => 
    [REQUEST_URI] => /tim/camel/
    [SCRIPT_NAME] => /tim/camel/index.php
    [PHP_SELF] => /tim/camel/index.php
    [REQUEST_TIME] => 1291468702
    [argv] => Array
        (
        )

    [argc] => 0
)

注意 REQUEST_METHOD 是 POST，但 argv 不包含消息正文。

简而言之，我需要将消息正文从“发件人”路由传输到“收件人”路由，以便它可以作为 POST 发送，但我以某种方式失败了。

提前致谢。

我找到了答案。为了解决这个问题，我必须将 Content Type 节点添加到标题并将正文设置为名称/值对，如下所示:

<route errorHandlerRef="dlc" autoStartup="true" inheritErrorHandler="true" id="route2" xmlns:ns2="http://camel.apache.org/schema/web" xmlns="http://camel.apache.org/schema/spring">
    <from uri="activemq:test"/>
    <setBody inheritErrorHandler="true" id="setBody2">
        <simple>name=${body}</simple>
    </setBody>
    <setHeader headerName="Content-Type" inheritErrorHandler="true" id="setHeader3">
        <constant>application/x-www-form-urlencoded;</constant>
    </setHeader>
    <setHeader headerName="CamelHttpMethod" inheritErrorHandler="true" id="setHeader4">
        <constant>POST</constant>
    </setHeader>
    <to uri="http://localhost/tim/camel/" inheritErrorHandler="true" id="to2"/>
</route>
