在我的代码中，我希望有一个主机列表，并向每个主机发送不同的参数。
目前我在数组中找到索引并使用它来确定输入
index = env.hosts.index(env.host_name)
在面料3中不再使用主机和host_name。
The primary API is now properly OOP: instantiate Connection objects and call their methods. These objects encapsulate all connection state (user, host, gateway, etc) and have their own SSH client instances.

在Fabric 2中，通过实例化SELECT z.*
FROM
(
SELECT *,
ROW_NUMBER() OVER (PARTITION BY [id] ORDER BY [action_timestamp] DESC) AS rowNum,
[new_state] AS [Last_State],
DATEADD(MONTH, 0, @date) AS [date]
FROM [dbo].[CR_hist_Data]
WHERE [action_timestamp_formatted] < DATEADD(MONTH, -1, @date)
) z
WHERE z.rowNum = 1
UNION
SELECT z.*
FROM
(
SELECT *,
ROW_NUMBER() OVER (PARTITION BY [id] ORDER BY [action_timestamp] DESC) AS rowNum,
[new_state] AS [Last_State],
DATEADD(MONTH, -1, @date) AS [date]
FROM [dbo].[CR_hist_Data]
WHERE [action_timestamp_formatted] < DATEADD(MONTH, -2, @date)
) z
WHERE z.rowNum = 1
UNION
SELECT z.*
FROM
(
SELECT *,
ROW_NUMBER() OVER (PARTITION BY [id] ORDER BY [action_timestamp] DESC) AS rowNum,
[new_state] AS [Last_State],
DATEADD(MONTH, -2, @date) AS [date]
FROM [dbo].[CR_hist_Data]
WHERE [action_timestamp_formatted] < DATEADD(MONTH, -3, @date)
) z
WHERE z.rowNum = 1;
etc....for 12 times
对象连接到主机。您可以通过调用Connection属性访问其主机：
host如果您需要连接到多个服务器，则需要实例化由多个连接组成的conn = Connection('192.168.11.12')
print(conn.host)
