1. 使用容器模板創建 AWS Lambda (.NET 5)

請參閱AWS官方文件的第一部分:.NET 5 AWS Lambda 支援容器映像文件.

2. 添加封裝相依性

這些依賴項是在此AWS環境中運行Chrome所必需的。

請根據以下說明修改 Docker 文件:

使用 .NET 5 的 AWS Lambda

AWS Lambda 與 .NET 7

AWS Lambda 與 .NET 8

3. 添加 IronPDF (Linux) NuGet 套件

安裝IronPdf.Linux

  1. 在方案總管中,右鍵點擊參考,管理 NuGet 套件

  2. 選擇瀏覽並搜尋 IronPdf.Linux

  3. 選擇套件並安裝。

4. 修改 FunctionHandler 代碼

此範例將從網頁建立 PDF 檔案IronPDF 網站並將其儲存到 /tmp。 為了查看此 PDF,您必須將其上傳至其他服務,如 S3。

在使用 IronPDF 於 AWS Lambda 時,有必要配置臨時文件夾。 請使用 TempFolderPathCustomDeploymentDirectory 屬性來執行此操作。

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

		'[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

		Dim Renderer = New IronPdf.ChromePdfRenderer()

		context.Logger.LogLine($"rendering Pdf")
		Dim pdfDoc = Renderer.RenderUrlAsPdf("https://ironpdf.com/")

		Dim guid As System.Guid = System.Guid.NewGuid()
		Dim 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($"COMPLETE!")
	Catch e As Exception
		context.Logger.LogLine($"[ERROR] FunctionHandler : {e.Message}")
	End Try

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

5. 增加記憶體和超時时间

IronPDF 需要比 Lambda 的預設值更多的時間和記憶體。 您可以在 aws-lambda-tools-defaults.json 中進行配置。 請調整此內容以符合您的功能。 在此範例中,我們將其設置為 512(MB)和 330(秒钟).

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

您也可以使用 Lambda 控制台更新此配置。 導航至AWS Lambda 記憶體配置指南文章了解更多信息。

6. 發布

請遵循 " 後半部分的指示。.NET 5 AWS Lambda 支援容器映像文件發布和測試您的 Lambda 函數的文件。

7. 試試看吧!

您可以使用 Lambda 函數來啟動此功能AWS Lambda 控制台或通過 Visual Studio 使用適用於 Visual Studio 的 AWS 工具包.
