Bidding announcement type classification service

This service is used as a preprocessing step for the Bidding Parsing Service (Premium Edition) and the Bid-winning Parsing Service (Premium Edition).

Debugging

Configure access credentials using environment variables

1. Notes:

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

   2. Do not save your AccessKey ID and AccessKey secret in your code. This practice poses a high risk of key leakage. Instead, use environment variables to store and access your credentials.

2. Configuration 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. Windows configuration

   1. Create a file for the environment variables. Add the NLP_AK_ENV and NLP_SK_ENV environment variables, and then write your AccessKey ID and AccessKey secret to the corresponding variables.

   2. Restart Windows.

To call the bidding announcement type classification service, set ServiceName to classify-type-bid.

Java code example

 * This example shows how to store the AccessKey ID and AccessKey secret in environment variables. You can also store them in a configuration file as needed.
 * Do not hardcode your AccessKey ID and AccessKey secret in your code. This practice poses a security threat from leaked keys.
