重要:必要設定

  • Zip 部署不受支持,因为 IronPDF 需要在运行时执行二进制文件。
  • 您必須將 PackageType 設置為 Image。 因為 IronPDF for Java 僅支持 Docker 部署。
  • 您必須使用 AmazonLinux2 docker 映像檔。
  • 您必須設置以下的 IronPdfEngineWorkingDirectory:
Setting.setIronPdfEngineWorkingDirectory(Paths.get("/tmp/"));
JAVA

必需,因為這是 AWS 允許的執行環境唯一路徑。

  • 增加 /tmp 的大小,預設值為512 MB。 請將其設定為至少 1024 MB。
  • ironpdf-engine-linux-x64 依賴項包括在您的項目中:
 <dependency>
    <groupId>com.ironsoftware</groupId>
    <artifactId>ironpdf-engine-linux-x64</artifactId>
    <version>2022.xx.x</version>
</dependency>
XML
  • 將 Lambda 逾時設定為 330 秒,因為啟動緩慢。
  • 將 Lambda 記憶體大小設置為至少 1024 MB。

快速開始使用 IntelliJ IDEA 的 AWS Toolkit(AWS SAM)

  1. 安裝工具:

    您可能也需要以下工具進行本地測試:

  2. 創建項目。 (文件 -> 新建 -> 專案...)

  3. 配置:

    • 套件類型:影像

    • Runtime:java8java11

    • SAM 模板:Maven

  4. 在您的 pom.xml 中添加以下依賴項:
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>2.0.3</version>
</dependency>

<dependency>
    <groupId>com.ironsoftware</groupId>
    <artifactId>ironpdf-engine-linux-x64</artifactId>
    <version>2022.11.1</version>
</dependency>

<dependency>
    <groupId>io.perfmark</groupId>
    <artifactId>perfmark-api</artifactId>
    <version>0.26.0</version>
</dependency>

<dependency>
    <groupId>io.grpc</groupId>
    <artifactId>grpc-okhttp</artifactId>
    <version>1.50.2</version>
</dependency>

<dependency>
    <groupId>io.grpc</groupId>
    <artifactId>grpc-netty-shaded</artifactId>
    <version>1.50.2</version>
</dependency>
XML
  1. App.java 中的 handleRequest 函數代碼更改為:
import com.ironsoftware.ironpdf.*;
public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
        APIGatewayProxyResponseEvent response = new APIGatewayProxyResponseEvent();
        Settings.setDebug(true); //optional
        Settings.setIronPdfEngineWorkingDirectory(Paths.get("/tmp/")); //requried!
        try {
            context.getLogger().log("RENDER PDF");
            PdfDocument pdf = PdfDocument.renderUrlAsPdf("https://www.google.com");
            context.getLogger().log("RENDER PDF SUCCESS");
            pdf.saveAs("/tmp/my-first-pdf.pdf");
            //Done! Now you can do anything with the pdf such as upload this pdf to S3.
            //return something..
            Map<String, String> headers = new HashMap<>();
            headers.put("Content-Type", "application/json");
            headers.put("X-Custom-Header", "application/json");
            APIGatewayProxyResponseEvent response = new APIGatewayProxyResponseEvent()
                    .withHeaders(headers);
            return response
                    .withStatusCode(200)
                    .withBody("ENJOY IRON-PDF!");
        } catch (Exception e) {
            return response
                    .withBody("{" + e.getMessage() + "}")
                    .withStatusCode(500);
        }
    }
JAVA
  1. template.yaml 中設定 Lambda 配置:
Globals:
  Function:
    Timeout: 400
    MemorySize: 2048
    EphemeralStorage:
      Size: 1024
#don't touch the other config    
YAML
  1. 將 Dockerfile 更新為以下內容:
  • 注意:對於Java8,請使用java8.al2映像檔,因為它使用AmazonLinux2,但java8使用舊的AmazonLinux

  1. 使用以下方式建構:
sam build -u
  1. 部署使用:
sam deploy --guided
