在 AWS Lambda 上使用 IronPdf 创建 PDF 文件

Translated

View the article in English

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

AWS Lambda with .NET 7

AWS Lambda with .NET 8

3. Add the IronPDF (Linux) NuGet Package

Install IronPdf.Linux

In Solution Explorer, right-click References, Manage NuGet Packages
Select Browse and search IronPdf.Linux
Select the package and install.

4. Modify FunctionHandler Code

This example will create a PDF file from a webpage IronPDF website and save it to /tmp. In order to view this PDF, you must upload it to another service such as S3.

It is necessary to configure the temporary folder when using IronPDF on AWS Lambda. Please use the TempFolderPath and CustomDeploymentDirectory properties to do this.

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;

		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. Increase Memory and Timeout

IronPDF requires more time and memory than the default value of Lambda. You can configure it in aws-lambda-tools-defaults.json. Please adjust this to match your function. In this example, we will set it to 512 (MB) and 330 (seconds).

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

You also can update this configuration using the Lambda console. Navigate to the AWS Lambda Memory Configuration Guide article for more information.

6. Publish

Please follow the instructions in the latter part of the '.NET 5 AWS Lambda Support with Container Images' document to publish and test your Lambda function.
