Cómo ejecutar IronPDF for Java en AWS Lambda

Importante: Configuración necesaria

• Despliegue Zip no es compatible ya que IronPDF requiere la ejecución de binarios en tiempo de ejecución.
• Debe configurar PackageType en Image porque IronPDF for Java solo admite la implementación de Docker.
• Debes utilizar una imagen Docker AmazonLinux2.
• Debe establecer el siguiente IronPdfEngineWorkingDirectory:

import com.ironsoftware.ironpdf.Settings;
import java.nio.file.Paths;

// Setting the working directory for IronPDF engine
Settings.setIronPdfEngineWorkingDirectory(Paths.get("/tmp/"));

import com.ironsoftware.ironpdf.Settings;
import java.nio.file.Paths;

// Setting the working directory for IronPDF engine
Settings.setIronPdfEngineWorkingDirectory(Paths.get("/tmp/"));

Nota: Esto es necesario porque es el único camino que AWS permite para el entorno de ejecución.

• Aumentar el tamaño de /tmp. El valor predeterminado es 512 MB. Por favor configúrelo a al menos 1024 MB.
• Incluya la dependencia ironpdf-engine-linux-x64 en su proyecto:

<dependency>
    <groupId>com.ironsoftware</groupId>
    <artifactId>ironpdf-engine-linux-x64</artifactId>
    <version>2022.xx.x</version>
</dependency>

<dependency>
    <groupId>com.ironsoftware</groupId>
    <artifactId>ironpdf-engine-linux-x64</artifactId>
    <version>2022.xx.x</version>
</dependency>

• Configure el tiempo de espera Lambda a 330 segundos debido a un inicio lento.
• Configure el tamaño de memoria de Lambda en al menos 1024 MB.

5. Cambie el código de función handleRequest en App.java a:

import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.events.APIGatewayProxyRequestEvent;
import com.amazonaws.services.lambda.runtime.events.APIGatewayProxyResponseEvent;
import com.ironsoftware.ironpdf.PdfDocument;
import com.ironsoftware.ironpdf.Settings;

import java.nio.file.Paths;
import java.util.HashMap;
import java.util.Map;

// AWS Lambda function to generate a PDF from a URL using IronPDF.
public class App {
    public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
        APIGatewayProxyResponseEvent response = new APIGatewayProxyResponseEvent();

        // Enable debugging for IronPDF (optional)
        Settings.setDebug(true);

        // Set the working directory for the IronPDF engine (required)
        Settings.setIronPdfEngineWorkingDirectory(Paths.get("/tmp/"));

        try {
            context.getLogger().log("RENDER PDF");

            // Render the PDF from a URL
            PdfDocument pdf = PdfDocument.renderUrlAsPdf("https://www.google.com");

            context.getLogger().log("RENDER PDF SUCCESS");

            // Save the generated PDF to a file
            pdf.saveAs("/tmp/my-first-pdf.pdf");

            // Set HTTP response headers
            Map<String, String> headers = new HashMap<>();
            headers.put("Content-Type", "application/json");
            headers.put("X-Custom-Header", "application/json");

            // Return the successful response
            return response
                    .withHeaders(headers)
                    .withStatusCode(200)
                    .withBody("ENJOY IRON-PDF!");

        } catch (Exception e) {
            // Return the error response
            return response
                    .withBody("{" + e.getMessage() + "}")
                    .withStatusCode(500);
        }
    }
}

import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.events.APIGatewayProxyRequestEvent;
import com.amazonaws.services.lambda.runtime.events.APIGatewayProxyResponseEvent;
import com.ironsoftware.ironpdf.PdfDocument;
import com.ironsoftware.ironpdf.Settings;

import java.nio.file.Paths;
import java.util.HashMap;
import java.util.Map;

// AWS Lambda function to generate a PDF from a URL using IronPDF.
public class App {
    public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
        APIGatewayProxyResponseEvent response = new APIGatewayProxyResponseEvent();

        // Enable debugging for IronPDF (optional)
        Settings.setDebug(true);

        // Set the working directory for the IronPDF engine (required)
        Settings.setIronPdfEngineWorkingDirectory(Paths.get("/tmp/"));

        try {
            context.getLogger().log("RENDER PDF");

            // Render the PDF from a URL
            PdfDocument pdf = PdfDocument.renderUrlAsPdf("https://www.google.com");

            context.getLogger().log("RENDER PDF SUCCESS");

            // Save the generated PDF to a file
            pdf.saveAs("/tmp/my-first-pdf.pdf");

            // Set HTTP response headers
            Map<String, String> headers = new HashMap<>();
            headers.put("Content-Type", "application/json");
            headers.put("X-Custom-Header", "application/json");

            // Return the successful response
            return response
                    .withHeaders(headers)
                    .withStatusCode(200)
                    .withBody("ENJOY IRON-PDF!");

        } catch (Exception e) {
            // Return the error response
            return response
                    .withBody("{" + e.getMessage() + "}")
                    .withStatusCode(500);
        }
    }
}

6. Establezca la configuración de Lambda en template.yaml:

Globals:
  Function:
    Timeout: 400
    MemorySize: 2048
    EphemeralStorage:
      Size: 1024
# Do not modify other configurations

Globals:
  Function:
    Timeout: 400
    MemorySize: 2048
    EphemeralStorage:
      Size: 1024
# Do not modify other configurations

7. Actualice Dockerfile:
   • Nota: Para Java 8, utilice imágenes java8.al2 porque usan AmazonLinux2, mientras que java8 usa el antiguo AmazonLinux.
