我有一个应用程序,需要将一个非常简单的消息放到远程队列。 使用的队列由第三方及其IBM WebSphere MQ(版本7.5)提供。
我尝试将amqmdnet.dll
与下面的示例代码一起使用,但我知道应该在我的服务器上安装MQ客户端来执行此操作。
所以我的问题: 有没有办法在没有所有这些要求的情况下将消息放入队列?像一个简单的REST或SOAP客户端? 我愿意使用不同的语言来实现这样一个组件,我只是不想在服务器上安装第三方应用程序(它的托管环境)

您可以选择MQC.TRANSPORT_MQSERIES_CLIENT
以使其在托管中运行,而不是选择会导致amqmdnet.dll
在非托管模式下运行并依赖其他非.NET dll的MQC.TRANSPORT_MQSERIES_MANAGED
模式,这意味着它不需要任何其他dll来运行。
即使在托管模式下,在MQ v7.5中,您也无法单独使用amqmdnet.dll
,在该版本中,IBM不支持此配置。在IBM MQ v8及更高版本中,IBM确实支持单独使用amqmdnet.dll
。您可以从以下链接之一下载MQ v8或MQ v9可再发行客户端。只需从zip文件中找到amqmdnet.dll
并使用它。
MQ完全向后兼容,从较高版本的客户端连接到MQ 7.5队列管理器不应该是一个问题。另请注意,MQ v7.5在2018年4月30日失去支持,为了保持IBM的支持,第三方需要升级或支付额外的资金以获得扩展支持。
