Question

我正在尝试从我的mongooseim服务器与rabbitmq服务器通信。为此，我首先将rabbitmq-client库（用于erlang）复制到我的apps目录，更新了我的makefile，然后重新编译了mongooseim代码。（根据here的指示）。这样我就可以编译没有错误的代码，并且可以看到amqp_client已经从mongooseim控制台启动了。现在，当我尝试从控制台运行amqp_connection：start（）时，我得到以下错误。如何解决这个问题？

(mongooseim@localhost)8> {ok, Connection} = amqp_connection:start(#amqp_params_network{}).

Answer 1

undef错误消息告诉我们rabbit_net模块或connection_string函数丢失，rabbit_net是rabbit_common包的一部分。我猜你没有添加rabbit_common。您可以在上一个问题 - here中找到您粘贴的网站上的包裹。使用rabbit_common.ez重复这些步骤，它应该有效。

从MongooseIM连接到RabbitMQ服务器
