ballerinax/googleapis.cloudnaturallanguage Ballerina library

Overview

This is a generated connector for Google Cloud Natural Language API v1 OpenAPI specification. Provides natural language understanding technologies, such as sentiment analysis, entity recognition, entity sentiment analysis, and other text annotations, to developers.

Prerequisites

Before using this connector in your Ballerina application, complete the following:

• Create a Google account
• Obtain tokens - Follow this link

Quickstart

To use the Google Cloud Natural Language connector in your Ballerina application, update the .bal file as follows:

Step 1: Import connector

First, import the ballerinax/googleapis.cloudnaturallanguage module into the Ballerina project.

import ballerinax/googleapis.cloudnaturallanguage;

Step 2: Create a new connector instance

Create a cloudnaturallanguage:ClientConfig with the OAuth2 tokens obtained, and initialize the connector with it.

cloudnaturallanguage:ClientConfig clientConfig = {
    auth: {
        clientId: <CLIENT_ID>,
        clientSecret: <CLIENT_SECRET>,
        refreshUrl: <REFRESH_URL>,
        refreshToken: <REFRESH_TOKEN>
    }
};

cloudnaturallanguage:Client baseClient = check new Client(clientConfig);

Step 3: Invoke connector operation

1. Now you can use the operations available within the connector. Note that they are in the form of remote operations.

   Following is an example on how to classify a document into categories using the connector.

   Classifies a document into categories

   public function main() {
       cloudnaturallanguage:Document document = {
           content: "<content>"
       };
       cloudnaturallanguage:ClassifyTextRequest classifyTextRequest = {
           document: document
       };
   
       cloudnaturallanguage:ClassifyTextResponse|error response = baseClient->classifytextDocuments(classifyTextRequest);
       if (response is cloudnaturallanguage:ClassifyTextResponse) {
           log:printInfo(response.toString());
       } else {
           log:printError(response.message());
       }
   }

2. Use bal run command to compile and run the Ballerina program.
