如何在 AWS Lambda 中运行 IronPDF for Java.

重要：必要设置

• 由于 IronPDF 需要在运行时执行二进制文件，因此不支持 Zip 部署。
• 您必须将 PackageType 设置为 Image ，因为 IronPDF for Java 仅支持 Docker 部署。
• 您必须使用 AmazonLinux2 Docker 镜像。
• 您必须设置以下 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/"));

注意：这是必须的，因为这是 AWS 允许的唯一执行环境路径。

• 增加 /tmp 大小。默认值为 512 MB。 请将其设置为至少 1024 MB。
• 在您的项目中包含 ironpdf-engine-linux-x64 依赖关系：

<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>

• 由于启动缓慢，将 Lambda 超时设置为 330 秒。
• 将 Lambda 内存大小至少设置为 1024 MB。

使用AWS Toolkit for IntelliJ IDEA (AWS SAM) 的快速入门

1.安装工具：

• IntelliJ IDEA - 下载 IntelliJ IDEA
• AWS 工具包 - 为 JetBrains 设置 AWS 工具包。
• SAM CLI - 为无服务器应用程序安装 SAM CLI

• Docker - Install Docker Community Edition

  可选项（用于本地测试）：

• Java 8 - 下载 Java SE 开发工具包 8
• Maven - 安装 Maven 的指南

2.创建项目： （<代码>文件</代码> -> <代码>新建</代码> -> <代码>项目...</代码）

3. 配置：
   • 包类型：Image
   • 运行时：<代码>java8</代码>或<代码>java11</代码
   • SAM 模板：<代码>Maven</代码

4. 将以下依赖项添加到你的 pom.xml：

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

5. 将 handleRequest 函数代码更改为 App.java：

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. 在 template.yaml 中设置 Lambda 配置：

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.更新 Dockerfile：

• 注意：对于 Java 8，使用 java8.al2 镜像，因为它们使用 AmazonLinux2，而 java8 使用旧的 AmazonLinux。
