管道管理
在开通服务时，系统会自动创建一个用户管道。您可以通过一系列接口管理管道（pipeline）。例如：SearchPipeline、QueryPipelineList、UpdatePipeline。
搜索管道
可以直接通过SearchPipeline接口搜索管道信息。
import os
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkcore.auth.credentials import AccessKeyCredential
from aliyunsdkmts.request.v20140618.SearchPipelineRequest import SearchPipelineRequest
# 读取环境变量中设置的ACCESS_KEY ACCESS_KEY_SECRET信息
credentials = AccessKeyCredential(os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID'], os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET'])
# region_id 为调用的服务地域ID，支持的地域参考 https://help.aliyun.com/document_detail/43248.html
client = AcsClient(region_id = 'cn-shanghai', credential = credentials)
request = SearchPipelineRequest()
request.set_accept_format('json')
response = client.do_action_with_exception(request);
# 输出打印
print(str(response, encoding='utf-8'))查询管道
如果已经知道pipelineId，可以通过pipelineId调用QueryPipelineList接口查询管道信息。
import os
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkcore.auth.credentials import AccessKeyCredential
from aliyunsdkmts.request.v20140618.QueryPipelineListRequest import QueryPipelineListRequest
# 读取环境变量中设置的ACCESS_KEY ACCESS_KEY_SECRET信息
credentials = AccessKeyCredential(os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID'], os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET'])
# region_id 为调用的服务地域ID，支持的地域参考 https://help.aliyun.com/document_detail/43248.html
client = AcsClient(region_id = 'cn-shanghai', credential = credentials)
request = QueryPipelineListRequest()
request.set_PipelineIds('9bad380c3d2cc4df9c6****')
request.set_accept_format('json')
response = client.do_action_with_exception(request);
# 输出打印
print(str(response, encoding='utf-8'))更新管道
通过UpdatePipeline更新管道信息，包括更新管道名称，状态。管道的状态包括Active、Paused。
import os

from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkcore.auth.credentials import AccessKeyCredential
from aliyunsdkmts.request.v20140618.UpdatePipelineRequest import UpdatePipelineRequest
# 读取环境变量中设置的ACCESS_KEY ACCESS_KEY_SECRET信息
credentials = AccessKeyCredential(os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID'], os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET'])
# region_id 为调用的服务地域ID，支持的地域参考 https://help.aliyun.com/document_detail/43248.html
client = AcsClient(region_id = 'cn-shanghai', credential = credentials)
request = UpdatePipelineRequest()
request.set_PipelineId('91c22c4df9c6****')
request.set_Name('update name')
request.set_State('Active')
response = client.do_action_with_exception(request);
# 输出打印
print(str(response, encoding='utf-8'))
