Como executar o IronPDF for Java no AWS Lambda

Importante: Configurações obrigatórias

• A implantação em formato Zip não é suportada, pois o IronPDF requer a execução de binários em tempo de execução.
• Você deve definir PackageType para Image porque o IronPDF for Java suporta apenas implantação em Docker.
• Você deve usar uma imagem Docker AmazonLinux2.
• Você deve definir o seguinte 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/"));

Observação: Isso é necessário porque é o único caminho que a AWS permite para o ambiente de execução.

• Aumente o tamanho do arquivo /tmp. O valor padrão é 512 MB. Por favor, defina para pelo menos 1024 MB.
• Inclua a dependência ironpdf-engine-linux-x64 em seu projeto:

<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>

• Defina o tempo limite do Lambda para 330 segundos devido a uma inicialização lenta.
• Defina o tamanho da memória Lambda para pelo menos 1024 MB.

Guia de Início Rápido com o AWS Toolkit para IntelliJ IDEA (AWS SAM)

1. Instalar ferramentas:

   • IntelliJ IDEA - Baixe o IntelliJ IDEA
   • AWS Toolkit - Configurar o AWS Toolkit para JetBrains
   • SAM CLI - Instale o SAM CLI para aplicações sem servidor
   • Docker - Instalar o Docker Community Edition

   Opcional (para testes locais):

   • Java 8 - Baixe o Java SE Development Kit 8
   • Maven - Orientações para instalar o Maven
2. Criar projeto: (File -> New -> Project...)

3. Configuração:
   • Tipo de pacote: Image
   • Tempo de execução: java8 ou java11
   • Modelo SAM: Maven

4. Adicione as seguintes dependências ao seu pom.xml:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>2.0.3</version>

5. Altere o código da função handleRequest em App.java para:

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. Configure o Lambda em 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. Atualizar Dockerfile:
   • Nota: Para Java 8, use imagens java8.al2 porque elas usam AmazonLinux2, enquanto java8 usa o antigo AmazonLinux.
