Feature overview
For information about VIN Code Recognition features and API parameters, see VIN Code Recognition.
Install the SDK package
For information about the SDK dependency packages for common languages, see SDK Overview.
Configure environment variables
Configure the ALIBABA_CLOUD_ACCESS_KEY_ID and ALIBABA_CLOUD_ACCESS_KEY_SECRET environment variables.
An Alibaba Cloud account has full access to all API operations. We recommend that you use a RAM user for API calls or routine O&M. For more information, see Create a RAM user.
Do not save your AccessKey ID or AccessKey Secret in project code. Otherwise, the AccessKey pair may be leaked and the security of all resources in your account may be compromised.
Configure environment variables on Linux and macOS
Open a terminal in IntelliJ IDEA.
Run the following commands to configure the environment variables.
Replace
<access_key_id>with the AccessKey ID of your RAM user and<access_key_secret>with the AccessKey Secret of your RAM user. If you need to configure more permissions, see Control access permissions using a RAM policy.export ALIBABA_CLOUD_ACCESS_KEY_ID=<access_key_id> export ALIBABA_CLOUD_ACCESS_KEY_SECRET=<access_key_secret>
Configure environment variables on Windows
Create a new environment variable file, add the environment variables
ALIBABA_CLOUD_ACCESS_KEY_IDandALIBABA_CLOUD_ACCESS_KEY_SECRET, and set them to the AccessKey ID and AccessKey Secret that you have prepared. Then, restart the Windows operating system. The following example uses Windows 10.Open File Explorer, right-click This PC, and then select Properties.
In the left-side navigation pane, click Advanced system settings.
On the Advanced tab of the System Properties dialog box, click Environment Variables.
In the Environment Variables dialog box, click New.
In the New System Variable dialog box, add the environment variables
ALIBABA_CLOUD_ACCESS_KEY_IDandALIBABA_CLOUD_ACCESS_KEY_SECRET, and set them to the AccessKey ID and AccessKey Secret that you have prepared.Restart the Windows operating system for the configurations to take effect.
