iOS集成Rabbit MQ 记录

参考文章

Rabbit MQ url配置示例，更多配置细则请查看(需要科学上网)
或者：http://bit.ly/ks8MXK

AMQP::Client.parse_connection_uri("amqp://dev.rabbitmq.com")            # => vhost is nil, so default ("/") will be used
AMQP::Client.parse_connection_uri("amqp://dev.rabbitmq.com/")           # => vhost is an empty string
AMQP::Client.parse_connection_uri("amqp://dev.rabbitmq.com/%2Fvault")   # => vhost is "/vault"
AMQP::Client.parse_connection_uri("amqp://dev.rabbitmq.com/production") # => vhost is "production"
AMQP::Client.parse_connection_uri("amqp://dev.rabbitmq.com/a.b.c")      # => vhost is "a.b.c"
AMQP::Client.parse_connection_uri("amqp://dev.rabbitmq.com/foo/bar")    # => ArgumentError

NSString *url5 = @"amqp://登录用户名:登录密码@ip地址或域名:端口号/虚拟主机名";
eg:
NSString *url5 = @"amqp://guest:guest@localhost:5672/Vhost";

代码很简单 基本上只要url配置对了，就可以了
发送

        let conn = RMQConnection(uri: url5,delegate: RMQConnectionDelegateLogger()
        conn.start()
        let ch = conn.createChannel()
        let q = ch.queue("test_queue_name") //随便起个就可以，与接收时保持一致即可
        let message = "Hello iOS!"
        guard let data = message.data(using: .utf8) else{
            return
        }
        ch.defaultExchange().publish(data,routingKey: q.name)
        print("[x] Send message:\(message)")
        conn.close()

接收

        let conn = RMQConnection(uri: url5, delegate: RMQConnectionDelegateLogger())
        conn.start()
        let ch = conn.createChannel()
        let q = ch.queue("test_queue_name") //与发送时保持一致即可
        
        print("[*] Waiting for messages.")
        q.subscribe({(_ message: RMQMessage) -> Void in
            print("[x] Received \(String(data: message.body, encoding: .utf8))")
            conn.close()
        })

Tips:
服务器给了相关配置之后一直没办法连接成功，尝试通过Android端接入，发现可以正常接入。
Android端配置如下：

        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("ip地址或域名");
        factory.setVirtualHost("/");
        factory.setPort(端口号);
        factory.setUsername("用户名");
        factory.setPassword("密码");

最后发现VirtualHost是"/",按照文档可以忽略，但实际上忽略无法连接成功
正确配置是

let url5 = "amqp://guest:guest@localhost:5672/%2F"

实际上"/"转义之后是%2F,改成这种格式之后就可以正常连接了

用户名，密码，domain，vhost 中如果包含特殊符号都需要经过转义之后再拼接到url中 才能正常访问
let uri = "amqp://\(mq_username):\(mq_password)@\(mq_domain):\(mq_port)/\(mq_vhost)"
