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

初始化配置对象 alibabacloud_tea_openapi.Config。

import os
from alibabacloud_tea_openapi import models as open_api_models

config = open_api_models.Config(
    // 必填，请确保代码运行环境设置了环境变量 ALIBABA_CLOUD_ACCESS_KEY_ID。
    access_key_id=os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID'],
    // 必填，请确保代码运行环境设置了环境变量 ALIBABA_CLOUD_ACCESS_KEY_SECRET。
    access_key_secret=os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET']
)
# 访问的域名
config.endpoint = 'mts.cn-hangzhou.aliyuncs.com'

实例化一个客户端，从 alibabacloud_mts20140618.Client 类生成对象 client 。

from alibabacloud_mts20140618.client import Client as Client
from alibabacloud_mts20140618 import models as models

client = Client(config)
