Python SDK使用说明

本文介绍Python SDK使用说明。请您按照以下步骤操作。

环境准备

Python 2.7+

SDK安装

1.安装阿里云核心SDK

sudo pip install aliyun-python-sdk-core

1. 安装阿里云视频直播SDK

sudo pip install aliyun-python-sdk-live

SDK更新

1. 更新阿里云核心SDK

sudo pip install aliyun-python-sdk-core --upgrade

1. 更新阿里云视频直播SDK

sudo pip install aliyun-python-sdk-live --upgrade

SDK移除

sudo pip uninstall aliyun-python-sdk-core
sudo pip uninstall aliyun-python-sdk-live

接口说明

以 DescribeLiveStreamsFrameRateAndBitRateData接口为例。

以下是SDK中的DescribeLiveStreamsFrameRateAndBitRateDataRequest.py

该文件中对于DescribeLiveStreamsFrameRateAndBitRateDataRequest这个类，有若干组一一对应的get_X和set_X方法，分别用于设定该 API 请求的参数，具体每一个请求参数对应的意义，您可以在阿里云官网的直播 API 文档中找到。

SDK使用

以v20161101版本为例。

以调用DescribeLiveStreamsFrameRateAndBitRateDataRequest接口为例。

# 引入aliyunsdkcore包
from aliyunsdkcore import client
# 引入aliyunsdklie包
from aliyunsdklive.request.v20161101 import DescribeLiveStreamsFrameRateAndBitRateDataRequest
# 初始化client
# AK和Secrect需要自己提供(可以在阿里云控制台中找到)
# 以访问cn-hangzhou region为例
clt = client.AcsClient(AK, Secret, 'cn-hangzhou')
# 构造需发起的API请求调用
request = DescribeLiveStreamsFrameRateAndBitRateDataRequest.DescribeLiveStreamsFrameRateAndBitRateDataRequest()
request.set_DomainName('qt1.alivecdn.com')
request.set_AppName('caster')
request.set_StreamName('cc8d5e157f5d4146afd091e246efd1f6')
# 发起请求
result = clt.do_action_with_exception(request)
# 请求结果
# result为请求结果的ResponseBody字符串
print result
# 如果您需要进一步对result进行处理,可以根据每个接口的返回格式,进行格式化处理并进一步分析或使用
# 对于DescribeLiveStreamsFrameRateAndBitRateDataRequest来说,它返回一个json格式的数据,我们可以用json包来处理这些response
import json
x = json.loads(result)
print x['RequestId']
print x['FrameRateAndBitRateInfos']
