AWS Translate using AWS JS SDK

 In this post, I will discuss how to use AWS Javascript SDK V3 for AWS Translate.

Prerequisite: Node.js should be pre-installed

Steps:

• Create a folder e.g. AWSTranslateApp
• From command prompt navigate to folder "AWSTranslateApp"
• Type npm init
• This will create Node project
• Install AWS JS SDK by typing "npm install @aws-sdk/client-translate" under folder "AWSTranslateApp"
• Now open the "AWSTranslateApp" folder in VS Code
• Create a file translateExample.js

Below is the code snippet for translateExample.js

const { TranslateClient, TranslateTextCommand } = require("@aws-sdk/client-translate");

 async function getTranslatedData(){

  const client = new TranslateClient({ region: "<region_name>", 

  credentials: {

    accessKeyId: '<access_key>', 

    secretAccessKey: '<secret_key>'

  } 

});

  const params = {

    SourceLanguageCode: "en",

    TargetLanguageCode: "es",

    Text: "Hello, world"

  };

      const command = new TranslateTextCommand(params);

      const data = await client.send(command);   

      const jsonData =await data.TranslatedText;

      console.log(jsonData);

  }

 getTranslatedData();

• Replace the region, access key, secret key with the actual values. In my case the region was 'us-east-1'.
• Once done, you can now run the program using below command from command prompt

        node translateExample

AWS Service Call from Java SDK

 Here in this post I will discuss how to use AWS Translate Service from Java Code.

Steps:

1. Add the below dependency in pom.xml

<dependency>

    <groupId>com.amazonaws</groupId>

    <artifactId>aws-java-sdk-translate</artifactId>

    <version>1.12.194</version>

</dependency>

2. Add below imports in Java File

import com.amazonaws.auth.AWSStaticCredentialsProvider;

import com.amazonaws.auth.BasicAWSCredentials;

import com.amazonaws.regions.Regions;

import com.amazonaws.services.translate.AmazonTranslate;

import com.amazonaws.services.translate.AmazonTranslateClient;

import com.amazonaws.services.translate.model.TranslateTextRequest;

import com.amazonaws.services.translate.model.TranslateTextResult;

3. Below is the code snippet; provide the accessKey & secretKey to access the service

BasicAWSCredentials credentials = new BasicAWSCredentials("<access_key>",

"<secret_key>");

AmazonTranslate translate = AmazonTranslateClient.builder()

.withCredentials(new AWSStaticCredentialsProvider(credentials)).withRegion(Regions.US_EAST_1).build();

TranslateTextRequest request = new TranslateTextRequest().withText("Hello, world").withSourceLanguageCode("en")

.withTargetLanguageCode("es");

TranslateTextResult result = translate.translateText(request);

System.out.println(result.getTranslatedText());

AWS Service Call from Postman

Many of the times you need to use AWS services via Postman for testing.

I am using Amazon Translate Service, below are the configuration made to call the service:

In Postman choose the Post method for call

Service URL: https://translate.us-east-1.amazonaws.com/

In "Authorization" tab choose "Type" "AWS Signature"

Provide AccessKey, SecretKey, AWS Region, Service Name

The region I am using is "us-east-1" , Service Name will be "translate"

Then Move to "Headers" tab & add the following Headers

Content-Type: application/x-amz-json-1.1

X-Amz-Target: AWSShineFrontendService_20170701.TranslateText

N.B. X-Amz-Date will be generated by Postman automatically

Under "Body", select "raw", and added the following sample body:

{

    "SourceLanguageCode": "en",

    "TargetLanguageCode": "es",

    "Text": "Hello, world"

}

Now hit the Send button & check the result.

Clicking on the "Code" in Postman you can also get the cod for Java/Node JS and many other languages.
