Question

我刚刚更新到google-cloud-pubsub版本0.28，其中Google将Python客户端重组为PublisherClient和SubscriberClient。我试图连接到localhost上的Pubsub模拟器，但是尽管设置了环境变量，它仍然连接到cloud pubsub服务，它可以列出来自cloud pubsub的所有主题，但不能列出来自模拟器的主题。

以下是我用来连接模拟器的代码

from google.cloud import pubsub
import os
os.environ['PUBSUB_EMULATOR_HOST'] = 'localhost:8085'
os.environ['GOOGLE_CLOUD_PROJECT'] = 'my-project'
publisher = pubsub.PublisherClient()
topic = 'projects/my-project/topics/abc'
publisher.get_topic(topic)

以下是例外：

Traceback (most recent call last):
  File "<input>", line 5, in <module>
  File "/Users/sx5640/Envs/uie/lib/python2.7/site-packages/google/cloud/pubsub_v1/_gapic.py", line 42, in <lambda>
