：Example of calling an API operation by using Simple Log Service SDK for Python

View the API documentation

Before you call an API operation, we recommend that you read the API documentation to learn about the parameters and permissions that are required to call the API operation. For more information, see List of operations by function.

Create a RAM user and grant permissions to the RAM user

If you have already created a RAM user and granted permissions to the RAM user, skip this step.

1. Log on to the RAM console.

2. Create a RAM user.

   1. In the left-side navigation pane, choose Identities > Users.

   2. On the Users page, click Create User.

   3. On the Create User page, set Logon Name and Display Name to config-openapi-operator, and select OpenAPI Access for Access Mode.

   4. Click OK.

      After you create a RAM user, the system automatically generates an AccessKey ID and an AccessKey secret for the RAM user. For more information, see Create an AccessKey pair. We recommend that you record the AccessKey pair. When you use the RAM user to call an API operation, you must enter the AccessKey pair.

3. Grant permissions to the RAM user.

   Note

   By default, a RAM user has no permissions. After you create a RAM user, you must attach system policies, such as AliyunLogFullAccess and AliyunLogReadOnlyAccess, or custom policies to the RAM user. For more information, see Overview. In this example, the AliyunLogReadOnlyAccess policy is attached to the RAM user. The AliyunLogReadOnlyAccess policy grants the read-only permissions on Simple Log Service resources.

   1. On the Users page, find the config-openapi-operator RAM user and click Add Permissions in the Actions column.

   2. In the Add Permissions panel, select AliyunLogReadOnlyAccess and click OK.

   3. Confirm the authorization result. Then, click Complete.

Call an API operation

In this example, Simple Log Service SDK for Python is used to call an API operation. If you use a Simple Log Service SDK in a different programming language, the following procedure also applies. For more information, see Simple Log Service SDKs.

Prepare a Python environment

Install Python. For more information, visit the official website of Python.

You can run the python -V command to view the version of Python that is installed.

Configure environment variables

To prevent security risks that are caused by hard coding the AccessKey pair into your business code, we recommend that you configure environment variables to manage the AccessKey pair.

• Linux or macOS operating system

  Replace <access_key_id> and <access_key_secret> in the following commands with the AccessKey ID and AccessKey secret of the RAM user. Then, run the following commands on your device:

  export ALIBABA_CLOUD_ACCESS_KEY_ID=<access_key_id>
  export ALIBABA_CLOUD_ACCESS_KEY_SECRET=<access_key_secret>

• Windows operating system

  Create an environment variable file, add the ALIBABA_CLOUD_ACCESS_KEY_ID and ALIBABA_CLOUD_ACCESS_KEY_SECRET environment variables, and write the AccessKey ID and AccessKey secret of the RAM user. Then, restart the Windows operating system.

Download the sample code

1. Visit ListProject.

2. On the Parameters tab, configure the parameters. For example, enter the name of the project whose information you want to query in the projectName field.

3. On the SDK Sample Code tab, select Python and click Download Project to download the sample code package.

4. Decompress the sample code package on your computer and go to the alibabacloud_sample directory.

Install dependencies

pip install alibabacloud-sls20201230

Run code

Run the sample.py file. The following sample response is returned:
