这些信息也在我们的网站上显示 - AWS Lambda IronPDF 指南

AWS 指导

1. 查看 AWS .NET 5 Lambda 支持和容器镜像
2. 创建并使用以下 Dockerfile：

# Use the .NET 5 AWS Lambda runtime as the base image
FROM public.ecr.aws/lambda/dotnet:5.0
WORKDIR /var/task

# Install the necessary dependencies for IronPDF
RUN yum install -y pango.x86_64 \
                   libXcomposite.x86_64 \
                   libXcursor.x86_64 \
                   libXdamage.x86_64 \
                   libXext.x86_64 \
                   libXi.x86_64 \

# This COPY command copies the .NET Lambda project's build artifacts from the host machine into the image.
COPY "bin/Release/lambda-publish" .

3. 将 IronPdf.Linux 包添加到您的解决方案中。
4. 修改 _FunctionHandler 代码 - 此示例将从网页( IronPDF )创建 PDF 并将其保存到 /tmp。 要查看此 PDF，必须将其上传到另一个服务，例如 S3。(此处有官方 AWS 示例 - AWS S3 基础知识)

// Define the function handler for AWS Lambda
public Casing FunctionHandler(string input, ILambdaContext context)
{
    try
    {
        // Start logging the function process with input details
        context.Logger.LogLine($"START FunctionHandler RequestId: {context.AwsRequestId} Input: {input}");

        var awsTmpPath = @"/tmp/"; // AWS temporary storage path

        // Optional: Enable debugging for IronPdf
        // IronPdf.Logging.Logger.EnableDebugging = true;
        // IronPdf.Logging.Logger.LogFilePath = awsTmpPath;
        // IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All;

        // Set your license key for IronPDF
        IronPdf.License.LicenseKey = "YOUR_LICENSE_KEY";

        // Configuration for IronPDF rendering
        IronPdf.Installation.ChromeGpuMode = IronPdf.Engines.Chrome.ChromeGpuModes.Disabled;
        IronPdf.Installation.DefaultRenderingEngine = IronPdf.Rendering.PdfRenderingEngine.Chrome;
        Environment.SetEnvironmentVariable("TEMP", awsTmpPath, EnvironmentVariableTarget.Process);
        Environment.SetEnvironmentVariable("TMP", awsTmpPath, EnvironmentVariableTarget.Process);
        IronPdf.Installation.TempFolderPath = awsTmpPath;
        IronPdf.Installation.CustomDeploymentDirectory = awsTmpPath;
        IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = true;

        context.Logger.LogLine($"Creating IronPdf.ChromePdfRenderer");

        // Create instance of ChromePdfRenderer and render PDF from URL
        var renderer = new IronPdf.ChromePdfRenderer();
        context.Logger.LogLine($"Rendering PDF");
        using var pdfDoc = renderer.RenderUrlAsPdf("https://ironpdf.com/");
        var guid = Guid.NewGuid();
        var fileName = $"/tmp/{input}_{guid}.pdf"; // Name for the PDF file

        // Save the rendered PDF document
        context.Logger.LogLine($"Saving PDF name : {fileName}");
        pdfDoc.SaveAs(fileName);

        // Here you can upload the saved PDF file to anywhere such as AWS S3.
        context.Logger.LogLine($"COMPLETE!");
    }
    catch (Exception e)
    {
        // Log errors if any occur
        context.Logger.LogLine($"[ERROR] FunctionHandler : {e.Message}");
    }

    // Return a new instance of Casing with lower and upper case input strings
    return new Casing(input?.ToLower(), input?.ToUpper());
}

// Casing record to hold lower and upper case strings
public record Casing(string Lower, string Upper);

// Define the function handler for AWS Lambda
public Casing FunctionHandler(string input, ILambdaContext context)
{
    try
    {
        // Start logging the function process with input details
        context.Logger.LogLine($"START FunctionHandler RequestId: {context.AwsRequestId} Input: {input}");

        var awsTmpPath = @"/tmp/"; // AWS temporary storage path

        // Optional: Enable debugging for IronPdf
        // IronPdf.Logging.Logger.EnableDebugging = true;
        // IronPdf.Logging.Logger.LogFilePath = awsTmpPath;
        // IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All;

        // Set your license key for IronPDF
        IronPdf.License.LicenseKey = "YOUR_LICENSE_KEY";

        // Configuration for IronPDF rendering
        IronPdf.Installation.ChromeGpuMode = IronPdf.Engines.Chrome.ChromeGpuModes.Disabled;
        IronPdf.Installation.DefaultRenderingEngine = IronPdf.Rendering.PdfRenderingEngine.Chrome;
        Environment.SetEnvironmentVariable("TEMP", awsTmpPath, EnvironmentVariableTarget.Process);
        Environment.SetEnvironmentVariable("TMP", awsTmpPath, EnvironmentVariableTarget.Process);
        IronPdf.Installation.TempFolderPath = awsTmpPath;
        IronPdf.Installation.CustomDeploymentDirectory = awsTmpPath;
        IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = true;

        context.Logger.LogLine($"Creating IronPdf.ChromePdfRenderer");

        // Create instance of ChromePdfRenderer and render PDF from URL
        var renderer = new IronPdf.ChromePdfRenderer();
        context.Logger.LogLine($"Rendering PDF");
        using var pdfDoc = renderer.RenderUrlAsPdf("https://ironpdf.com/");
        var guid = Guid.NewGuid();
        var fileName = $"/tmp/{input}_{guid}.pdf"; // Name for the PDF file

        // Save the rendered PDF document
        context.Logger.LogLine($"Saving PDF name : {fileName}");
        pdfDoc.SaveAs(fileName);

        // Here you can upload the saved PDF file to anywhere such as AWS S3.
        context.Logger.LogLine($"COMPLETE!");
    }
    catch (Exception e)
    {
        // Log errors if any occur
        context.Logger.LogLine($"[ERROR] FunctionHandler : {e.Message}");
    }

    // Return a new instance of Casing with lower and upper case input strings
    return new Casing(input?.ToLower(), input?.ToUpper());
}

// Casing record to hold lower and upper case strings
public record Casing(string Lower, string Upper);

5. 增加内存和超时 - IronPDF 需要比 Lambda 默认值更多的时间和内存。 这可以在 aws-lambda-tools-defaults.json 中进行配置。 调整这些值以匹配您的函数需求。

在此示例中，我们设置为 512 MB 和 330 秒：

"function-memory-size": 512,
"function-timeout": 330,

此配置也可以通过 Lambda 控制台更新 - AWS Lambda 内存配置。

6. 请按照文档的最后部分发布并尝试 Lambda 函数 AWS .NET 5 Lambda 支持和容器镜像
7. Lambda 函数还可以通过 Lambda 控制台调用，AWS Lambda 控制台 或通过 Visual Studio 使用 AWS Toolkit for Visual Studio 进行调用。

如果收到"GPU 进程无法使用"消息，可能是安装时未使用管理员权限运行。 请尝试以管理员/根用户身份重新运行软件。 或者，将以下内容添加到您的 Dockerfile 中：

RUN chmod 755 "runtimes/linux-x64/native/IronCefSubprocess"
