Basic concepts of phpamqp Message Queue RabbitMQ (2)

Connection: AMQPConnection first look at the server's existing link rabbitmqctl. The bat-qlist_connections is displayed as the air line below the code and then view the link connect. php? Php $ connectnewAMQPConnection (); $ connect-connect (); while (true) {} rabbitmqctl. bat-qlist_connections now serves

Connection: AMQPConnection first check the existing Server link rabbitmqctl. bat-q list_connections. It is displayed as null. Run the following code and check the link connect. php? Php $ connect = new AMQPConnection (); $ connect-connect (); while (true) {} rabbitmqctl. bat-q list_connections services

Connection: AMQPConnection

Check the existing connection of the server.

Rabbitmqctl. bat-q list_connections is blank

Run the following code and check the link.

Connect. php

 connect();while (true) {    }

Rabbitmqctl. bat-q list_connections current server Link

Channel: AMQPChannel

Rabbitmqctl. bat-q list_channels is blank

Run the Code channel. php.

 connect();$channel = new AMQPChannel($connect);while (true) {    }

Rabbitmqctl. bat-q list_channels:

Switch: Exchange

Rabbitmqctl. bat-q list_exchanges:

Run exchange. php

 connect();$channel = new AMQPChannel($connect);$exchange = new AMQPExchange($channel);$exchange->setName('exchange_name');$exchange->setType(AMQP_EX_TYPE_DIRECT);$exchange->declare();while (true) {    }

Rabbitmqctl. bat-q list_exchanges:

If the queue service is not restarted, The exchange_name switch will always exist.

Queue: AMQPQueue

Rabbitmqctl. bat-q list_queues:

Run queue. php In cmd.

 connect();$channel = new AMQPChannel($connect);$exchange = new AMQPExchange($channel);$exchange->setName('exchange_name');$exchange->setType(AMQP_EX_TYPE_DIRECT);$exchange->declare();$queue = new AMQPQueue($channel);$queue->setName('queue_name');$queue->declare();while (true) {    }

Run rabbitmqctl. bat-q list_queues.

Bind & routing_key

Rabbitmqctl. bat-q list_bindings:

Run the following php code bind. php:

 connect();$channel = new AMQPChannel($connect);$exchange = new AMQPExchange($channel);$exchange->setName('exchange_name');$exchange->setType(AMQP_EX_TYPE_DIRECT);$exchange->declare();$queue = new AMQPQueue($channel);$queue->setName('queue_name');$queue->declare();$queue->bind('exchange_name', 'routing_key');while (true) {    }

Run rabbitmqctl. bat-q list_bindings again.

Information: Envelope

Next we will change the above bind. php to an acceptor (Information processing end)

 connect();$channel = new AMQPChannel($connect);$exchange = new AMQPExchange($channel);$exchange->setName('exchange_name');$exchange->setType(AMQP_EX_TYPE_DIRECT);$exchange->declare();$queue = new AMQPQueue($channel);$queue->setName('queue_name');$queue->declare();$queue->bind('exchange_name', 'routing_key');while (true) {    $queue->consume('functionName');}function functionName($envelope,$queue) {    var_dump($envelope->getBody());}

Run the following in dos:

Let's write another sender, envelope. php.

 connect();$channel = new AMQPChannel($connect);$exchange = new AMQPExchange($channel);$exchange->setName('exchange_name');$exchange->setType(AMQP_EX_TYPE_DIRECT);$exchange->declare();$exchange->publish('hello world','routing_key');$connect->disconnect();

After running envelope. php, you can see that the receiving end has received the message.
