RabbitMQ API
RabbitMQ Server提供了丰富的http api。
举个列子
需要HTTP基本身份验证。默认的用户名/密码为guest/guest。
这些返回值得意义我从官网搬来解释,为了避免翻译的问题导致大家理解的误差这里直接给出原文
cluster_name | The name of the entire cluster, as set with rabbitmqctl set_cluster_name . |
erlang_full_version | A string with extended detail about the Erlang VM and how it was compiled, for the node connected to. |
erlang_version | A string with the Erlang version of the node connected to. As clusters should all run the same version this can be taken as representing the cluster. |
exchange_types | A list of all exchange types available. |
listeners | All (non-HTTP) network listeners for all nodes in the cluster. (See contexts in /api/nodes for HTTP). |
management_version | Version of the management plugin in use. |
message_stats | A message_stats object for everything the user can see - for all vhosts regardless of permissions in the case of monitoring and administrator users, and for all vhosts the user has access to for other users. |
node | The name of the cluster node this management plugin instance is running on. |
object_totals | An object containing global counts of all connections, channels, exchanges, queues and consumers, subject to the same visibility rules as for message_stats . |
queue_totals | An object containing sums of the messages , messages_ready and messages_unacknowledged fields for all queues, again subject to the same visibility rules as for message_stats . |
rabbitmq_version | Version of RabbitMQ on the node which processed this request. |
statistics_db_node | Name of the cluster node hosting the management statistics database. |
statistics_level | Whether the node is running fine or coarse statistics. |
又或者通过api查询虚拟主机
许多api的URI需要一个虚拟主机路径的一部分的名字,因为名字只有唯一在一个虚拟主机识别物体。作为默认的虚拟主机称为“/”,这??将需要被编码为“%2F”。
在我的demo程序中对应的api功能可以通过这里的功能来实现
其更丰富的功能可以参考官网说明文档 http://hg.rabbitmq.com/rabbitmq-management/raw-file/3646dee55e02/priv/www-api/help.html
以及 http://hg.rabbitmq.com/rabbitmq-management/raw-file/rabbitmq_v3_3_5/priv/www/api/index.html
一般来说我们常用的我在应用程序中已经给出 例如查看所有队列等
RabbitMQ CommandLine
除了丰富的http api,rabbitmq server自然也有其很全面命令行。
例如查询所有exchange。
查询所有队列以及他们包含的消息数目
rabbitmqctl更多的命令说明参考 http://www.rabbitmq.com/man/rabbitmqctl.1.man.html
Message的BasicGet于consume的区别
consume的功能上一张介绍过,basicget更偏向于我们平时用过的其他类型的MessageQueue,它就是最基本的接受消息,consume的消费针对basicget来说属于一个长连接于短连接的区别。
消费者关系一旦确定,基本上默认它就是在侦听通道的消息是否在生产。而basicget则是由客户端手动来控制。
在demo中在下图所示处区分
如果你选择了消费消息,那么基本上代码层面是这样来完成的
1 2 3 4 5 6 7 8 9 | var consumer = new QueueingBasicConsumer(channel); channel.BasicQos(0, 1, false ); channel.BasicConsume(queue.name, rbAckTrue.Checked, consumer); while ( true ) { var e = consumer.Queue.Dequeue(); MessageBox.Show( string .Format( "队列{0}获取消息{1},线程id为{2}" , queue.name, Encoding.ASCII.GetString(e.Body), Process.GetCurrentProcess().Id)); Thread.Sleep(1000); } |
