基于ZeroMQ的高性能分布式RPC框架：Zerorpc

Zerorpc是一個基于ZeroMQ和MessagePack開發的遠程過程調用協議（RPC）實現。和 Zerorpc 一起使用的 Service API 被稱為 zeroservice。Zerorpc 可以通過編程或命令行方式調用。

它允許你：

• 不用修改代碼即可顯露python模塊
• 通過命令行遠程調用這些模塊

如何把你代碼中的對象暴露為一個zeroservice？

class Cooler(object):
    """ Various convenience methods to make things cooler. """

    def add_man(self, sentence):
        """ End a sentence with ", man!" to make it sound cooler, and
        return the result. """
        return sentence + ", man!"

    def add_42(self, n):
        """ Add 42 to an integer argument to make it cooler, and return the
        result. """
        return n + 42

    def boat(self, sentence):
        """ Replace a sentence with "I'm on a boat!", and return that,
        because it's cooler. """
        return "I'm on a boat!"

import zerorpc

s = zerorpc.Server(Cooler())
s.bind("tcp://0.0.0.0:4242")
s.run()

運行以上代碼，在另一個終端，嘗試連接這個zeroservice

$ zerorpc -j tcp://localhost:4242 add_42 1
43
$ zerorpc tcp://localhost:4242 add_man 'I own a mint-condition Volkswagen Golf'
"I own a mint-condition Volkswagen Golf, man!"
$ zerorpc tcp://localhost:4242 boat 'I own a mint-condition Volkswagen Golf, man!'
"I'm on a boat!"
