阿里云SDK：代理配置

V2.0 SDK代理配置方式

• 支持通过运行时参数（RuntimeOption）配置当前请求的代理。

  import os
  
  from alibabacloud_ecs20140526.client import Client as EcsClient
  from alibabacloud_ecs20140526.models import DescribeRegionsRequest
  from alibabacloud_tea_openapi.models import Config
  from alibabacloud_tea_util.models import RuntimeOptions
  
  config = Config(
      access_key_id=os.environ.get('ALIBABA_CLOUD_ACCESS_KEY_ID'),
      access_key_secret=os.environ.get('ALIBABA_CLOUD_ACCESS_KEY_SECRET'),
      endpoint='ecs-cn-hangzhou.aliyuncs.com'
  )
  ecs_client = EcsClient(config)
  
  runtimeOptions = RuntimeOptions(
      http_proxy='http://127.0.0.1:9898',
      https_proxy='http://user:password@127.0.0.1:8989'
  )
  request = DescribeRegionsRequest()
  response = ecs_client.describe_regions_with_options(request, runtimeOptions)
  print(response.body)
  

• 在初始化客户端阶段，支持通过Config对请求的代理进行设置。

  import os
  
  from alibabacloud_ecs20140526.client import Client as EcsClient
  from alibabacloud_ecs20140526.models import DescribeRegionsRequest
  from alibabacloud_tea_openapi.models import Config
  from alibabacloud_tea_util.models import RuntimeOptions
  
  config = Config(
      access_key_id=os.environ.get('ALIBABA_CLOUD_ACCESS_KEY_ID'),
      access_key_secret=os.environ.get('ALIBABA_CLOUD_ACCESS_KEY_SECRET'),
      endpoint='ecs-cn-hangzhou.aliyuncs.com',
      http_proxy='http://127.0.0.1:9898',
      https_proxy='http://user:password@127.0.0.1:8989'
  )
  ecs_client = EcsClient(config)
  
  runtimeOptions = RuntimeOptions()
  request = DescribeRegionsRequest()
  response = ecs_client.describe_regions_with_options(request, runtimeOptions)
  print(response.body)
  

• 支持通过环境变量配置代理：

  • HTTP_PROXY 或者 http_proxy

  • HTTPS_PROXY或者 https_proxy
