HuaweiCloud Python Software Development Kit (Python SDK)

The HuaweiCloud Python SDK allows you to easily work with Huawei Cloud services such as Elastic Compute Service (ECS) and Virtual Private Cloud(VPC) without the need to handle API related tasks.

This document introduces how to obtain and use HuaweiCloud Python SDK.

Getting Started

• To use HuaweiCloud Python SDK, you must have Huawei Cloud account as well as the Access Key and Secret key of the HuaweiCloud account.

  The accessKey is required when initializing {Service}Client. You can create an AccessKey in the Huawei Cloud console. For more information, see My Credentials.

• HuaweiCloud Python SDK requires python 3 or later.

Install Python SDK

HuaweiCloud Python SDK supports Python 3 or later. Run python --version to check the version of Python.

• Use python pip

  Run the following command to install the individual libraries of HuaweiCloud services:

   # Install the core library
   pip install huaweicloudsdkcore
  
   # Install the VPC management library
   pip install huaweicloudsdkvpc
  

• Install from source

  Run the following command to install the individual libraries of HuaweiCloud services:

   # Install the core library
   cd huaweicloudsdkcore-${version}
   python setup.py install
  
   # Install the VPC management library
   cd huaweicloudsdkvpc-${version}
   python setup.py install
  

Use Python SDK

1. Import the required modules as follows:

   from huaweicloudsdkcore.auth.credentials import BasicCredentials
   from huaweicloudsdkcore.exceptions import exceptions
   from huaweicloudsdkcore.http.http_config import HttpConfig
   from huaweicloudsdkvpc.v2 import VpcClient
   

2. Config {Service}Client Configurations

   # Using the default configuration
   config = HttpConfig.get_default_config()
   
   # Set Proxy if needed
   config.proxy_protocol = 'http'
   config.proxy_host = 'proxy.huaweicloud.com'
   config.proxy_port = 80
   config.proxy_user = 'test'
   config.proxy_password = 'test'
   
   # Skip ssl certifaction checking while using https protocal if needed
   config.ignore_ssl_verification = True
   

3. Initialize the {Service}Client instance:

   credentials = BasicCredentials(ak, sk, project_id)
   
   vpc_client = VpcClient.new_builder(VpcClient) \
       .with_config(config) \
       .with_credentials(credentials) \
       .with_endpoint(endpoint) \
       .build()
   

   where:

   • ak is the access key id for your account.
   • sk is the secret access key for your account.
   • project_id is the id of the project.
   • endpoint is the service specific endpoints, see Regions and Endpoints

4. Send a request and print response.

   # Initialize a request and set parameters
   response = client.list_vpcs()
   print(respones)
   

Code example

The following example shows how to query a list of VPC in a specific region. Substitute the values for {your ak string}, {your sk string}, {your endpoint} and {your project id}.

# coding: utf-8


from huaweicloudsdkcore.auth.credentials import BasicCredentials
from huaweicloudsdkcore.exceptions import exceptions
from huaweicloudsdkcore.http.http_config import HttpConfig
from huaweicloudsdkvpc.v2 import VpcClient


def list_vpc(client):
    try:
        response = client.list_vpcs()
        print(response)
    except exceptions.ClientRequestException as e:
        print(e.status_code)
        print(e.request_id)
        print(e.error_code)
        print(e.error_msg)


if __name__ == "__main__":
    ak = "{your ak string}"
    sk = "{your sk string}"
    endpoint = "{your endpoint}"
    project_id = "{your project id}"

    config = HttpConfig.get_default_config()
    config.ignore_ssl_verification = True
    credentials = BasicCredentials(ak, sk, project_id)

    vpc_client = VpcClient.new_builder(VpcClient) \
        .with_config(config) \
        .with_credentials(credentials) \
        .with_endpoint(endpoint) \
        .build()

    list_vpc(vpc_client)
