This topic describes how to install and use ApsaraDB RDS SDK for Python.

Debugging

Alibaba Cloud provides OpenAPI Explorer, which simplify API usage. You can use OpenAPI Explorer to search for API operations, call API operations, and dynamically generate SDK sample code.

Prerequisites

  • An AccessKey pair is created. For more information, see Create an AccessKey.
    Note We recommend that you create a RAM user and grant the RAM user the permissions to access ApsaraDB RDS instances. Then, you can use the AccessKey pair of the RAM user to call ApsaraDB RDS SDK for Python. This allows you to protect the AccessKey pair of your Alibaba Cloud account. For more information, see Implement access control by using RAM.
  • Python is installed.

Precautions

Make sure that the logged-on account has the required permissions. For more information, see Use RAM for resource authorization.

Install ApsaraDB RDS SDK for Python

  1. Visit the Python SDK page at the official GitHub.
  2. Download the ApsaraDB RDS SDK for Python software package. Then, install ApsaraDB RDS SDK for Python by following the instructions that are provided in the README file.

Use ApsaraDB RDS SDK for Python

  1. Import the ApsaraDB RDS SDK for Python software package. 
    from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkrds.request.v20140815.DescribeSQLLogRecordsRequest import DescribeSQLLogRecordsRequest
  2. Create an AcsClient. 
    client = AcsClient(
"<access-key-id>", 
"<access-key-secret>",
"<region-id>")
    Note You can call the DescribeRegions operation to query the most recent region list.
  3. Configure the endpoint that is used to connect to your RDS instance. 
    client.addEndpoint(
"<region-id>", 
"<product>", 
"<endpoint>");
    Note For more information about endpoints, see the "Table 1" table.

  4. Create a request to query details about your RDS instance. Then, configure the request parameters. 
    request =DescribeDBInstanceAttributeRequest();
request.set_DBInstanceId("The name of your RDS instance");
  5. Initialize the AcsClient. 
    response = client.do_action_with_exception(request)
  6. View the response. 
    print response

Examples

  1. Create a primary RDS instance.

    Sample request:

    from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkrds.request.v20140815.DescribeDBInstancePerformanceRequest import DescribeDBInstancePerformanceRequest
from aliyunsdkrds.request.v20140815.CreateDBInstanceRequest import CreateDBInstanceRequest

client = AcsClient(
        "<access-key-id>",
        "<access-key-secret>",
        "cn-hangzhou"
        );
request =CreateDBInstanceRequest();
request.set_Engine("PostgreSQL");
request.set_EngineVersion("10.0");
request.set_DBInstanceClass("pg.n1.micro.1");
request.set_DBInstanceStorage("20");
request.set_DBInstanceNetType("Intranet");
request.set_DBInstanceDescription("aaa");
request.set_SecurityIPList("127.0.0.1");
request.set_PayType("Postpaid");
request.set_ZoneId("cn-hangzhou-b");
request.set_InstanceNetworkType("Classic");
request.set_Period("Month");
request.set_UsedTime("2");
try:
        response = client.do_action_with_exception(request)
        print response
except ServerException as e:
        print e
except ClientException as e:
        print e

    Sample response:

    {
  "OrderId":"20279634xxxxxxx",
  "DBInstanceId":"pgm-xxxxxxx",
  "RequestId":"BAF2A62B-804B-4C6C-BEE4-BAD2CA4C79E1"
}
  2. Change the specifications of an RDS instance.

request.set_ZoneId("cn-hangzhou-b");
request.set_InstanceNetworkType("Classic");
try:
        response = client.do_action_with_exception(request)
        print response
except ServerException as e:
        print e
except ClientException as e:
        print e

    Sample response:

    {
        "OrderId": "1214369xxxxxxx", 
        "ConnectionString": "rr-bpxxxxxxx.mysql.rds.aliyuncs.com", 
        "DBInstanceId": "rr-bpxxxxxxx", 
        "Port": "3306", 
        "RequestId": "1E43AAE0-BEE8-43DA-860D-EAF2AA0724DC"

}
