python-qpid-proton示例,向azure发送消息不起作用 [英] python-qpid-proton examples, send message to azure not working
问题描述
我正在尝试使用python-qpid-proton版本0.9.1将消息发送到Azure服务总线队列.
I'm trying to use python-qpid-proton version 0.9.1 to send a message to a Azure Service Bus queue.
examples/python/messenger/
中的示例接受格式为amqps://<user>:<password>@<server>/<queue name>
的地址,因此我可以成功地将消息发送到我在Azure上拥有的队列中.问题是我无法控制很多事情,也就是说,我真的看不到发送是否失败.最终,我想保留这些消息,以防Internet连接暂时断开.
The examples in examples/python/messenger/
accept addresses of the form amqps://<user>:<password>@<server>/<queue name>
, and I can successfully send messages to the queue I have on Azure with it. The problem with this is that I can't control much of what's going on, namely I can't really see if the sending failed. Eventually I want to persist the messages in case the internet connection goes down temporarily.
示例代码examples/python/db_send.py
和examples/python/simple_send.py
在这方面似乎更有用,因为它们使用MessagingHandler
而不是Messenger
类.但是,当我运行它们时,出现此错误:
The example code examples/python/db_send.py
and examples/python/simple_send.py
seem to be more useful with this aspects, as they use the MessagingHandler
instead of the Messenger
class. But when I run them, I get this error:
./simple_send.py -a amqps://send:mxirestofmypassword@testsoton.servicebus.windows.net/queue2
Traceback (most recent call last):

raise ValueError("Not a valid port number or service name: '%s'" % value)
ValueError: Not a valid port number or service name: 'mxitheresto'
在我看来,它无法正确解析地址.我粘贴了与以前相同的地址.我也将其粘贴到python解释器中,如下所示:
Seems to me like it does not parse the address correctly. I pasted the same address as before. And I also pasted it into the python interpreter, like this:
>>> import proton
>>> u = proton.Url("amqps://send:mxirestofmypassword@testsoton.servicebus.windows.net/queue2")
>>> # no error, and I can access all the parameters:
>>> u.port
5671
>>> u.username
send
>>> # ...
如果我使用没有用户名和密码的本地连接,则可以正常工作.如果我不使用任何用户名和密码,但由于无法通过身份验证而显然无法正常工作,就会越过这一点.
It works fine if I use a local connection with no username and password. Gets past this point if I don't use any username and password but obviously does not work as it fails authentication.
我可以使用MessagingHandler
类并指定用户名和密码来将消息发送到远程(例如在Azure上)吗?
Is there any way I can use the MessagingHandler
class and specify username and password to send messages to a remote (like on Azure)?
推荐答案
我尝试运行qpid示例"simple_send.py",但没有任何错误.该示例程序可以请求Azure服务总线,但无法使用AMQPS方案建立发送方连接.
I tried to run the qpid example "simple_send.py", I don't got any error. The example program can request the Azure Service Bus, but it can't establish the sender connection with AMQPS scheme.
根据MSDF官方文档 https://msdn.microsoft. com/en-us/library/azure/jj841070.aspx ,则可以使用Messenger类将消息发送到Azure Service Bus.
According to MSDF offical document https://msdn.microsoft.com/en-us/library/azure/jj841070.aspx, you can use the Messenger class to send messages to Azure Service Bus.
简单而完整的示例代码如下:
The simple completed sample code is as follows:
from proton import Messenger, Message
messenger = Messenger()
message = Message()
message.address = "amqps://<shared_access_policy_name>:<shared_access_policy_key>@pandaservibus.servicebus.windows.net/testqueue"
message.body = u"This is a text string"
messenger.put(message)
messenger.send()
您可以获取共享访问策略名称&键在"Azure服务总线队列"页面的配置"选项卡上.
You can get the shared access policy name & key at the tab "CONFIGURE" of Azure Service Bus Queue page.
最好的问候.
示例代码(克服不可靠的互联网连接):
Sample code (Overcome unreliable internet connection):
from proton import Messenger, Message
from time import sleep
message = Message()
message.address = "amqps://<shared_access_policy_name>:<shared_access_policy_key>@pandaservibus.servicebus.windows.net/testqueue"
message.body = u"This is a text string"
print('start')
retry = True
print("Send Msg")
while retry:
try:
messenger = Messenger()
messenger.put(message)
messenger.send()
retry = False
print "Sent"
except:
print "Retry"
sleep(2)
print "End"
如果要成功检查已发送消息的单个,我建议使用Service Bus REST API.成功发送消息后,您可以获得响应状态代码201.关于服务总线REST API,请参考 https://msdn.microsoft .com/en-us/library/azure/hh780786.aspx 和 https://msdn.microsoft.com/library/dn170477.aspx .
If you want to check the singal of sent messages successfully, I suggest to use the Service Bus REST API. You can get the response status code 201 when send messages successfully. About Service Bus REST APIs, please refer to https://msdn.microsoft.com/en-us/library/azure/hh780786.aspx and https://msdn.microsoft.com/library/dn170477.aspx.
