rabbitmq-rpc 0.1.3

A modified rabbit-rpc of https://github.com/MidTin/rabbit-rpc

RPC based on rabbitmq, cloned from here

How To Use

The orignal code can just be runned in console and has problems in windows(Server side). So I modified some code. Now, the server side supports both pika.BlockConnection and pika.SelectionConnection. In BlockConnection mode, the server side can only be runned in single thread. In SelectionConnection mode, the server can be runned in multi-threads(Not in windows).

• Install:

pip install rabbitmq-rpc

• Usage:
  1.Create rabbitmq account in your rabbitmq server.
  2.Run server.py first and then run client.py

• Server.py

from rabbitmq_rpc import server as Server
server = Server.RPCServer(queue_name='default',
                          amqp_url = "amqp://yourname:yourpasswd@10.147.17.135:5672/",
                          threaded=False)

@server.consumer()
def add(a, b):
    return a+b

if __name__ == '__main__':
    server.run()

• Client.py

from rabbitmq_rpc.client import RPCClient
import time

def add(i):
    t1 = time.time()
    client = RPCClient(amqp_url='amqp://yourname:yourpasswd@10.147.17.135:5672/')
    res = client.call_add(0, i)
    t2= time.time()
    print(f"{0} + {i} = {res} RPC Time Cost: {t2-t1:.2f}")
    return res

for i in range(300):
    obj = add(i)

• Client with flask: client_with_flask.py

from rabbitmq_rpc.client import RPCClient
import flask
web = flask.Flask(__name__)
web.debug = True
import time

def add(i):
    t1 = time.time()
    client = RPCClient(amqp_url='amqp://yourname:yourpasswd@10.147.17.135:5672/')
    res = client.call_add(0, i)
    t2= time.time()
    print(f"{0} + {i} = {res} RPC Time Cost: {t2-t1:.2f}")
    return res

@web.route('/web/<n>')
def test_web(n):
    res = add(int(n))
    return str(res)
if __name__ == '__main__':
    # Notice, In default, flask enabled threading. 
    # If single-thread is needed, pass in 'threaded=False' option
    web.run(host = '0.0.0.0', use_reloader = False)

*Note: RPCClient is not thread-safe. This is because pika is not thread-safe. So, create a RPCClient object only in one thread. DO NOT use it in multi-threads. *

简述
----

这是对 RabbitMQ 的 Pika_ 库进行封装的，一套简易 RPC 客户端/服务端库。


安装说明
--------

::

    pip install rabbit-rpc
    


使用事例
--------

服务端
~~~~~~

::

    # project/consumers.py

    from rabbit_rpc.consumer import consumer

    @consumer(name='add')
    def add(a, b):
        return a + b


    # project shell
    rabbit_rpc worker --amqp 'amqp://guest:guest@localhost:5672/'


    # with django

    rabbit_rpc worker --amqp 'amqp://guest:guest@localhost:5672/' --django project
    


客户端
~~~~~~

::
    
    from rabbit_rpc.client import RPCClient

    client = RPCClient(amqp_url='amqp://guest:guest@localhost:5672/')
    ret = client.call_add(1, 1, timeout=1)

    # or ignore result
    client.call_add(1, 1, ignore_result=True)

    # specify routing_key
    client.call_add(1, 1, routing_key='default')
