Use MPS SDK for Python - ApsaraVideo Media Processing - Alibaba Cloud Documentation Center

This topic describes how to initialize the client of ApsaraVideo Media Processing (MPS) SDK for Python.

Obtain an AccessKey pair from environment variables

You can define the environment variables ALIBABA_CLOUD_ACCESS_KEY_ID and ALIBABA_CLOUD_ACCESS_KEY_SECRET to configure the default credentials. When you call an API operation, the system reads the AccessKey pair from the default credentials and uses the AccessKey pair to complete authentication. For more information, see Configure environment variables in Linux, macOS, and Windows.

Initialize the client

Initialize the alibabacloud_tea_openapi.Config object.

import os
from alibabacloud_tea_openapi import models as open_api_models

config = open_api_models.Config(
    // Required. Make sure that the ALIBABA_CLOUD_ACCESS_KEY_ID environment variable is configured in the code runtime environment. 
    access_key_id=os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID'],
    // Required. Make sure that the ALIBABA_CLOUD_ACCESS_KEY_SECRET environment variable is configured in the code runtime environment. 
    access_key_secret=os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET']
)
# Specify the endpoint.
config.endpoint = 'mts.cn-hangzhou.aliyuncs.com'

Instantiate a client object from the alibabacloud_mts20140618.Client class.

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

client = Client(config)

Sample code:

import os
import sys
