1.使用容器模板创建 AWS Lambda(.NET 5)

请参考AWS此官方文件的第一部分:使用容器映像支持 .NET 5 AWS Lambda.

2.添加软件包依赖关系

这些依赖项是在此AWS环境中运行Chrome所必需的。

请根据以下指示修改 Docker 文件:

使用 .NET 5 的 AWS Lambda

<script src="https://gist.github.com/ironsoftwarebuild/7f2265f7751240398fb532bd318fc90c.js"></script>
<script src="https://gist.github.com/ironsoftwarebuild/7f2265f7751240398fb532bd318fc90c.js"></script>
HTML

AWS Lambda 与 .NET 7

<script src="https://gist.github.com/ironsoftwarebuild/ea399e109586f3ac29ebd43d1d0f6285.js"></script>

AWS Lambda 与 .NET 8

<script src="https://gist.github.com/ironsoftwarebuild/b700ca3ee47f405c257e72b2f8a33d52.js"></script>
<script src="https://gist.github.com/ironsoftwarebuild/b700ca3ee47f405c257e72b2f8a33d52.js"></script>

3.添加 IronPdf.Linux NuGet 软件包

安装 IronPdf.Linux

  1. 在解决方案资源管理器中,右键单击引用,管理NuGet程序包

  2. 选择浏览并搜索 "IronPdf.Linux

  3. 选择软件包并安装。

4.修改函数处理程序代码

此示例将从网页创建 PDF 文件IronPDF 网站并将其保存到 /tmp。 要查看此 PDF,您必须将其上传到 S3 等其他服务。

在 AWS Lambda 上使用 IronPDF 时,有必要配置临时文件夹。 请使用TempFolderPathCustomDeploymentDirectory属性进行翻译。

public Casing FunctionHandler(string input, ILambdaContext context)
{
    try
    {
        context.Logger.LogLine($"START FunctionHandler RequestId: {context.AwsRequestId} Input: {input}");

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

        //[optional] enable logging (please uncomment these code if you face any problem)
        //IronPdf.Logging.Logger.EnableDebugging = true;
        //IronPdf.Logging.Logger.LogFilePath = awsTmpPath;
        //IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All;

        //set your license key
        IronPdf.License.LicenseKey = "YOUR_LICENSE_KEY";

        //set ChromeGpuMode to Disabled
        IronPdf.Installation.ChromeGpuMode = IronPdf.Engines.Chrome.ChromeGpuModes.Disabled;

        //set IronPDF Temp Path
        IronPdf.Installation.TempFolderPath = awsTmpPath;
        IronPdf.Installation.CustomDeploymentDirectory = awsTmpPath;

        //set auto LinuxAndDockerDependenciesAutoConfig
        IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = true;

        context.Logger.LogLine($"creating IronPdf.ChromePdfRenderer");
        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"; //save file to /tmp

        context.Logger.LogLine($"saving pdf name : {fileName}");
        pdfDoc.SaveAs(fileName);

        //you can upload the saved PDF file to anywhere such as S3. 

        context.Logger.LogLine($"COMPLETE!");
    }
    catch (Exception e)
    {
        context.Logger.LogLine($"[ERROR] FunctionHandler : {e.Message}");
    }

    return new Casing(input?.ToLower(), input?.ToUpper());
}
public Casing FunctionHandler(string input, ILambdaContext context)
{
    try
    {
        context.Logger.LogLine($"START FunctionHandler RequestId: {context.AwsRequestId} Input: {input}");

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

        //[optional] enable logging (please uncomment these code if you face any problem)
        //IronPdf.Logging.Logger.EnableDebugging = true;
        //IronPdf.Logging.Logger.LogFilePath = awsTmpPath;
        //IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All;

        //set your license key
        IronPdf.License.LicenseKey = "YOUR_LICENSE_KEY";

        //set ChromeGpuMode to Disabled
        IronPdf.Installation.ChromeGpuMode = IronPdf.Engines.Chrome.ChromeGpuModes.Disabled;

        //set IronPDF Temp Path
        IronPdf.Installation.TempFolderPath = awsTmpPath;
        IronPdf.Installation.CustomDeploymentDirectory = awsTmpPath;

        //set auto LinuxAndDockerDependenciesAutoConfig
        IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = true;

        context.Logger.LogLine($"creating IronPdf.ChromePdfRenderer");
        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"; //save file to /tmp

        context.Logger.LogLine($"saving pdf name : {fileName}");
        pdfDoc.SaveAs(fileName);

        //you can upload the saved PDF file to anywhere such as S3. 

        context.Logger.LogLine($"COMPLETE!");
    }
    catch (Exception e)
    {
        context.Logger.LogLine($"[ERROR] FunctionHandler : {e.Message}");
    }

    return new Casing(input?.ToLower(), input?.ToUpper());
}
Public Function FunctionHandler(ByVal input As String, ByVal context As ILambdaContext) As Casing
	Try
		context.Logger.LogLine($"START FunctionHandler RequestId: {context.AwsRequestId} Input: {input}")

		Dim awsTmpPath = "/tmp/" ' AWS temporary storage

	End Try

	Return New Casing(input?.ToLower(), input?.ToUpper())
End Function

5. 增加内存和超时时间

IronPdf 需要比 Lambda 默认值更多的时间和内存。 您可以在 aws-lambda-tools-defaults.json 中进行配置。 请根据您的功能进行调整。 在本例中,我们将其设置为 512(MB)和 330(秒).

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

您还可以使用 Lambda 控制台更新此配置。 导航至AWS Lambda 内存配置指南文章获取更多信息。

6. 发布

请按照".NET "后半部分的说明进行翻译。使用容器映像支持 .NET 5 AWS Lambda'文档来发布和测试您的 Lambda 函数。

7.试用!

您可以使用AWS Lambda 控制台或通过 Visual Studio 使用用于 Visual Studio 的 AWS 工具包.
