What are ROS SDKs - - Alibaba Cloud Documentation Center

Resource Orchestration Service (ROS) supports the following programming languages: Java, Python, PHP, .NET, Go, Node.js, and C++.

The following table lists the download links and usage notes of the SDKs for these languages. For more information, visit OpenAPI Explorer.

Configure access credentials

Linux and macOS

In this example, the ALIBABA_CLOUD_ACCESS_KEY_ID and ALIBABA_CLOUD_ACCESS_KEY_SECRET environment variables are configured. You can replace the variable names based on your business requirements, such as OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET.

Create the .bash_profile file.
Note
If you configure environment variables for the first time, you can run the touch ~/.bash_profile command to create the configuration file. If the configuration file already exists, run the vim ~/.bash_profile command to edit the configuration file.
```
touch ~/.bash_profile
vim ~/.bash_profile
```

Configure the .bash_profile file.

# Replace <ACCESS_KEY_ID> and <ACCESS_KEY_SECRET> in the following commands with your AccessKey ID and AccessKey secret. 
# Replace the variable names based on your business requirements, such as OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET. 
export ALIBABA_CLOUD_ACCESS_KEY_ID=<ACCESS_KEY_ID>
export ALIBABA_CLOUD_ACCESS_KEY_SECRET=<ACCESS_KEY_SECRET>

Save the file after the configuration.

Use the .bash_profile file.

# Run the following command in the configuration file.
source ~/.bash_profile
# Check whether the configuration takes effect.
echo $ALIBABA_CLOUD_ACCESS_KEY_ID

If the valid AccessKey pair is returned, the configuration is successful.

Important

After you configure the environment variables, restart your development tools or services, such as the integrated development environment (IDE). Otherwise, the new settings may not take effect as expected.

Windows

Use GUI

Procedure

If you want to use GUI to configure environment variables in Windows 10, perform the following steps:

On the Windows desktop, right-click This PC and select Properties. On the page that appears, click Advanced system settings. In the System Properties dialog box, click Environment Variables on the Advanced tab. In the Environment Variables dialog box, click New in the User variables or System variables section. Then, configure the variables described in the following table.

Variable	Example
AccessKey ID	Variable name: ALIBABA_CLOUD_ACCESS_KEY_ID Variable value: LTAI4GDty8ab9W4Y1D****
AccessKey Secret	Variable name: ALIBABA_CLOUD_ACCESS_KEY_SECRET Variable value: IrVTNZNy5yQelTETg0cZML3TQn****

Check whether the configuration is successful.
On the Windows desktop, click Start or press Win + R. In the Run dialog box, enter cmd. Then, click OK or press the Enter key. On the page that appears, run the echo %ALIBABA_CLOUD_ACCESS_KEY_ID% and echo %ALIBABA_CLOUD_ACCESS_KEY_SECRET% commands. If the valid AccessKey pair is returned, the configuration is successful.

Use CMD

Procedure
Open a Command Prompt window as an administrator and run the following commands to add environment variables in the operating system:
```
setx ALIBABA_CLOUD_ACCESS_KEY_ID LTAI4GDty8ab9W4Y1D**** /M
setx ALIBABA_CLOUD_ACCESS_KEY_SECRET IrVTNZNy5yQelTETg0cZML3TQn**** /M
```
/M indicates that the environment variable is of system level. You cannot use this parameter when you configure a user-level environment variable.
Check whether the configuration is successful.
On the Windows desktop, click Start or press Win + R. In the Run dialog box, enter cmd. Then, click OK or press the Enter key. On the page that appears, run the echo %ALIBABA_CLOUD_ACCESS_KEY_ID% and echo %ALIBABA_CLOUD_ACCESS_KEY_SECRET% commands. If the valid AccessKey pair is returned, the configuration is successful.

Use Windows PowerShell

In PowerShell, configure new environment variables. The environment variables apply to all new sessions.

[System.Environment]::SetEnvironmentVariable('ALIBABA_CLOUD_ACCESS_KEY_ID', 'LTAI4GDty8ab9W4Y1D****', [System.EnvironmentVariableTarget]::User)
[System.Environment]::SetEnvironmentVariable('ALIBABA_CLOUD_ACCESS_KEY_SECRET', 'IrVTNZNy5yQelTETg0cZML3TQn****', [System.EnvironmentVariableTarget]::User)

Configure environment variables for all users. You must run the following commands as a administrator.

[System.Environment]::SetEnvironmentVariable('ALIBABA_CLOUD_ACCESS_KEY_ID', 'LTAI4GDty8ab9W4Y1D****', [System.EnvironmentVariableTarget]::Machine)
[System.Environment]::SetEnvironmentVariable('ALIBABA_CLOUD_ACCESS_KEY_SECRET', 'IrVTNZNy5yQelTETg0cZML3TQn****', [System.EnvironmentVariableTarget]::Machine)

Configure temporary environment variables. The environment variables apply only to the current session.

$env:ALIBABA_CLOUD_ACCESS_KEY_ID = "LTAI4GDty8ab9W4Y1D****"
$env:ALIBABA_CLOUD_ACCESS_KEY_SECRET = "IrVTNZNy5yQelTETg0cZML3TQn****"

In PowerShell, run the Get-ChildItem env:ALIBABA_CLOUD_ACCESS_KEY_ID and Get-ChildItem env:ALIBABA_CLOUD_ACCESS_KEY_SECRET commands. If the valid AccessKey pair is returned, the configuration is successful.
