媒体处理PythonSDK如何使用_媒体处理(MPS)-阿里云帮助中心

本文介绍Python SDK初始化Client的流程。

系统变量读取

阿里云SDK支持通过定义ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET环境变量来创建默认的访问凭证。调用接口时，程序直接访问凭证，读取您的访问密钥（即AccessKey）并自动完成鉴权。详细配置方式，请参见在Linux、macOS和Windows系统配置环境变量。

初始化

创建AcsClient实例。

# 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)

创建request，并设置参数。

# 以查询管道接口为例
request = QueryPipelineListRequest()
request.set_PipelineIds("9bad31a2b3c22c4df9c6****")
request.set_accept_format('json')

发起API请求并显示返回值。

response = client.do_action_with_exception(request)
# 输出打印
print(str(response, encoding='utf-8'))
