Service activation and resource plan purchase

Before you use the service, confirm that it is activated. After the service is activated, you can purchase a resource plan.

• Service activation: Activation page

• Resource plan purchase: Purchase page

Service invocation and debugging

Configure access credentials (AKSK) using environment variables

1. Notes:

   1. An Alibaba Cloud account AccessKey has full permissions for all APIs, which poses a high security risk. We strongly recommend that you create and use a Resource Access Management (RAM) user for API access or daily operations and maintenance (O&M). To create a RAM user, log on to the RAM console.

   2. Do not hard-code your AccessKey ID and AccessKey secret in your code. This practice can lead to key leakage. Instead, configure environment variables to store and access your AccessKey pair.

2. Configuration method for 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 for an account.

3. Method for configuring Windows

   1. Create an environment variable file. Add the NLP_AK_ENV and NLP_SK_ENV environment variables, and set their values to your AccessKey ID and AccessKey secret.

   2. Restart the Windows operating system.

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;
            }
        }
