與snakemq蟒蛇斷言錯誤3.2.1

Question

我通過教程工作在這裏找到： http://www.snakemq.net/doc/tutorial.html

這裏是我的代碼：

import snakemq.link 
import snakemq.packeter 
import snakemq.messaging 
import snakemq.message 

#Build Stack 

my_link = snakemq.link.Link() 
my_packeter = snakemq.packeter.Packeter(my_link) 
my_messaging = snakemq.messaging.Message("tyler", "", my_packeter) 

#Tyler 

my_link.add_listener(("", 4000)) 
my_link.add_connector(("localhost", 4001)) 

#Sally 

my_link.add_connector(("localhost", 4000)) 
my_link.add_connector(("localhost", 4001)) 

#Paul 

my_link.add_connector(("localhost", 4000)) 
my_link.add_listener(("", 4001)) 

#Run link loop (it drives the whole stack) 

my_link.loop() 

#Tyler wants to send a message to Sally 
#drop after 30 seconds if the message can't be delivered 

message = snakemq.message.Message(b"Hello", ttl = 600) 
my_messaging.send_message("Sally", message) 

#receiving callback 

def on_recv(conn, ident, message): 
    print(ident, message) 

my_messaging.on_message_recv.add(on_recv) 

我收到的錯誤：

Traceback (most recent call last):
File "C:/Users/Owner/Desktop/snakemq tutorial/test.py", line 10, in my_messaging = snakemq.messaging.Message("tyler", "", my_packeter)
File "C:\Python32\lib\site-packages\snakemq-1.2-py3.2.egg\snakem\message.py",
line 30, in init assert type(data) == bytes

看起來您正在錯誤地構建Message。

根據商務部，http://www.snakemq.net/doc/api/messaging.html#message，構造函數是

class snakemq.message.Message(data, ttl=0, flags=0, uuid=None) 

但在這一行，

my_messaging = snakemq.messaging.Message("tyler", "", my_packeter) 

你逝去的"tyler"，""和my_packeter不函數定義相匹配。

你應該試試這個

my_messaging = snakemq.messaging.Message(b"tyler")
