Question

我正在尝试通过在本地运行ActiveMQ来调试一些JMS代码-使用Docker映像rmohr/activemq:5.15.4-alpine-并使用cURL读取发布到该主题的消息。这通常可以正常工作，但是我没有得到消息的实际内容。

我正在做的是：

curl -v -XGET http://admin:admin@localhost:8161/api/message?destination=topic://Events&json=true&oneShot=true

其工作方式如下：

> GET /api/message?destination=topic://Events&json=true&oneShot=true HTTP/1.1
> Host: localhost:8161
> Authorization: Basic YWRtaW46YWRtaW4=
> User-Agent: curl/7.54.0
> Accept: */*
>

< HTTP/1.1 200 OK
< Date: Tue, 20 Nov 2018 17:09:03 GMT
< X-FRAME-OPTIONS: SAMEORIGIN
< Set-Cookie: JSESSIONID=mcjaka6dsuz6534j0gj0gfnv;Path=/api
< Expires: Thu, 01 Jan 1970 00:00:00 GMT

< destination: topic://Events
< id: ID:b8b750274409-46243-1542707161912-1:23:1:1:6
< eventTime$iso8601: 2018-11-20T17:09:13.216Z
< eventTime$millis: 1542733753216
< eventName: ProcessItemEvent
< Transfer-Encoding: chunked
< Server: Jetty(9.2.22.v20170606)
<

但是，不会返回消息的实际有效负载。如果我摘下json=true&oneShot=true，则会得到以下提示：

{ [5 bytes data]

但仅此而已。这些消息的有效载荷数据应该超过5个字节。

使这些消息正确通过时我缺少什么？

Answer 1

您正在订阅topic://Events。可能所有事件信息都位于http响应的标头中，而ActiveMQ并未在正文中添加任何其他内容吗？

< destination: topic://Events
< id: ID:b8b750274409-46243-1542707161912-1:23:1:1:6
< eventTime$iso8601: 2018-11-20T17:09:13.216Z
< eventTime$millis: 1542733753216
< eventName: ProcessItemEven

如果要将消息发布到特定主题，请说“ foo.bar”，您需要订阅topic://foo.bar。

我尝试了您的命令。如下所示，我 am 收到消息正文。

是否正在接收终端中未显示的二进制数据？您可以尝试将邮件正文保存到文件中吗？例如curl -o body.dat -v -XGET ...

$ curl -v -XGET 'http://admin:admin@localhost:8161/api/message?destination=topic://bayCarrState'
> GET /api/message?destination=topic://bayCarrState HTTP/1.1
> Authorization: Basic YWRtaW46YnJva2VyYWRtaW4=
> User-Agent: curl/7.29.0
> Host: localhost:8161
> Accept: */*
