這篇文章給大家分享的是有關RabbitMQ發送端接收端生產者消費者的示例分析的內容。小編覺得挺實用的，因此分享給大家做個參考，一起跟隨小編過來看看吧。

connection = pika.BlockingConnection(pika.ConnectionParameters(
    'localhost'))#rabbit默認端口5672 建立一個基本的 socket連接
channel = connection.channel()#聲明一個管道 在管道里面發消息

# 聲明queue
channel.queue_declare(queue='hello')

# n RabbitMQ a message can never be sent directly to the queue, it always needs to go through an exchange.
channel.basic_publish(exchange='',
                      routing_key='hello',#queue名字
                      body='Hello World!') #body 發送的消息
print(" [x] Sent 'Hello World!'")

# You may ask why we declare the queue again ? we have already declared it in our previous code.
# We could avoid that if we were sure that the queue already exists. For example if send.py program
# was run before. But we're not yet sure which program to run first. In such cases it's a good
# practice to repeat declaring the queue in both programs.

defcallback(ch, method, properties, body):#處理消息
    print("---->",ch,method,properties)#ch 管道內存對象地址 method:發給queue的信息
    print(" [x] Received %r"% body)

channel.basic_consume(#消費消息
              callback,#如果收到消息，就調用CALLBACK函數來處理消息
           queue='hello',#從哪個隊列里收消息
              #no_ack=True)#no acknowledgement 不確認 開啟的話表示不確認消息是否接收 接沒接收都不會給服務器端發消息 如果客戶端沒收到消息就忽略了
              #關閉的話就要服務器就要確認消息是否接收，沒有確認到接收消息就會一直保留消息,會自動轉到另一個客戶端，socket一斷，rabbitMQ就將消息轉給另一個客戶端
              #發送端生產者發送一條消息，被消費者接受者收到了，消費者接收端處理完之后自動給生產者發送端發一個確認，說消息處理完了，然后生產者發送端才會把消息從隊列里刪除，只要沒收到確認就不會刪除，如果生產者發送端沒收到確認，就會把消息轉給另一個消費者接收端
