AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Returns the configuration information of the Lambda function and a presigned URL link to the .zip file you uploaded with CreateFunction so you can download the .zip file. Note that the URL is valid for up to 10 minutes. The configuration information is the same information you provided as parameters when uploading the function.

Using the optional Qualifier parameter, you can specify a specific function version for which you want this information. If you don't specify this parameter, the API uses unqualified function ARN which return information about the $LATEST version of the Lambda function. For more information, see AWS Lambda Function Versioning and Aliases.

This operation requires permission for the lambda:GetFunction action.

Note:

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginGetFunction and EndGetFunction. For Unity the operation does not take CancellationToken as a parameter, and instead takes AmazonServiceCallback<GetFunctionRequest, GetFunctionResponse> and AsyncOptions as additional parameters.

Namespace: Amazon.Lambda
Assembly: AWSSDK.Lambda.dll
Version: 3.x.y.z

Syntax

C#
public abstract Task<GetFunctionResponse> GetFunctionAsync(
         String functionName,
         CancellationToken cancellationToken
)
Parameters
functionName
Type: System.String

The Lambda function name. You can specify a function name (for example, Thumbnail) or you can specify Amazon Resource Name (ARN) of the function (for example, arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda also allows you to specify a partial ARN (for example, account-id:Thumbnail). Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 characters in length.

cancellationToken
Type: System.Threading.CancellationToken

A cancellation token that can be used by other objects or threads to receive notice of cancellation.

Return Value
The response from the GetFunction service method, as returned by Lambda.

Exceptions

ExceptionCondition
InvalidParameterValueException One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception. You will also get this exception if you have selected a deprecated runtime, such as Node v0.10.42.
ResourceNotFoundException The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.
ServiceException The AWS Lambda service encountered an internal error.
TooManyRequestsException
