}

use jwt and EncodingAESKey Encode the data object to get the encrypted character string

const signedData = jwths256.encode(EncodingAESKey, {
      uid: "xjlsj33lasfaf", //Unique user id that identifies the user, which can be openid
      data: {}
    }
)

# Calling the Open Platform Semantic Interface
