尝试为项目测试 libcloud 的 ECS 驱动程序。

我写了一个简单的测试：

with open("conf.json") as f:
    data = json.loads(f.read())

driver = get_driver(getattr(Provider,'ECS'))

with open('.cloud_credentials/'+data['provider']+'/access_id', 'r') as myfile:
    ACCESS_KEY_ID = myfile.read().replace('\n', '')
    print ACCESS_KEY_ID

with open('.cloud_credentials/'+data['provider']+'/secret_key', 'r') as myfile:
    SECRET_KEY = myfile.read().replace('\n', '')
    print SECRET_KEY


timer.start()
conn = driver(access_id = ACCESS_KEY_ID,
              secret = SECRET_KEY,
              region = 'us-east-1')
timer.stop()


cluster = conn.create_cluster('pippo','us-east-1')

但是运行它会产生这个错误：

Traceback (most recent call last):
  File "launch.py", line 32, in <module>
    cluster = conn.create_cluster('pippo',data['region'])
  File "/home/sergio/anaconda2/lib/python2.7/site-packages/libcloud/container/drivers/ecs.py", line 151, in create_cluster
    headers=self._get_headers('CreateCluster')

    headers=headers, stream=stream)

    r = adapter.send(request, **kwargs)

    raise ConnectionError(e, request=request)

我认为问题在于包含该 %s 的主机字符串。在库中挖掘看起来该字符串是在文件中初始化的虚拟字符串：

/libcloud/container/drivers/ecs.py

我想这些文件中应该有一个函数应该覆盖基本字符串，由于某些原因可能不会被调用，但是作为 libcloud 库的新手，很难找到罪魁祸首。

奇怪的是，检查正在发送的标头，看起来它们包含正确的（？）地址：

headers: {'Host': u'ecs.us-east-1.amazonaws.com', 'User-Agent': 'libcloud/2.2.1 (Amazon Elastic Container Service) ', 'Content-Type': 'application/x-amz-json-1.1', 'Accept-Encoding': 'gzip,deflate', 'x-amz-target': 'AmazonEC2ContainerServiceV20141113.CreateCluster'}

有更多经验的人可以指出我正确的方向吗？将不胜感激。

这看起来像一个错误，这不是你做过的事情。
