Service activation and resource plan purchase

Before you start, ensure that the service is activated. After the service is activated, you can purchase a resource plan.

• Activate service: Activation link

• Purchase resource plan: Purchase link

Service invocation and debugging

For more information about model invocation, see Model invocation.

For more information about software development kit (SDK) examples, see SDK examples.

Configure access credentials using environment variables

1. Notes:

   1. The AccessKey pair of an Alibaba Cloud account has permissions to call all API operations. This poses a high security risk. For improved security, we recommend that you create and use a Resource Access Management (RAM) user to call API operations or perform routine O&M. To create a RAM user, log on to the RAM console.

   2. To prevent security risks that arise from key leaks, do not hard-code your AccessKey ID and AccessKey secret in your code. Instead, configure them as environment variables.

2. Configuring Linux and macOS

   export NLP_AK_ENV=<access_key_id>
   export NLP_SK_ENV=<access_key_secret>

   Replace <access_key_id> with your AccessKey ID and <access_key_secret> with your AccessKey secret. For more information about how to obtain an AccessKey ID and an AccessKey secret, see Step 2: Obtain an AccessKey pair.

3. Configure a Windows system

   1. Create an environment variable file. Add the NLP_AK_ENV and NLP_SK_ENV environment variables and write your AccessKey ID and AccessKey secret to the file.

   2. Restart Windows.

Java code example

class MsgDO{
            private String role;
            private String words;
            public MsgDO(String role,String words) {
                this.role = role;
                this.words = words;
            }
            public String getRole() {
                return role;
            }
            public void setRole(String role) {
                this.role = role;
            }
            public String getWords() {
                return words;
            }
            public void setWords(String words) {
                this.words = words;
