Types

type AddPermissionInput 

type AddPermissionInput struct {
	// The AWS Lambda action you want to allow in this statement. Each Lambda action
	// is a string starting with "lambda:" followed by the API name (see Operations).
	// For example, "lambda:CreateFunction". You can use wildcard ("lambda:*") to
	// grant permission for all AWS Lambda actions.
	Action *string `type:"string" required:"true"`

	// Name of the Lambda function whose access policy you are updating by adding
	// a new permission.
	//
	//  You can specify an unqualified 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 only the account ID qualifier (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 character in length.
	FunctionName *string `location:"uri" locationName:"FunctionName" type:"string" required:"true"`

	// The principal who is getting this permission. It can be Amazon S3 service
	// Principal ("s3.amazonaws.com") if you want Amazon S3 to invoke the function,
	// an AWS account ID if you are granting cross-account permission, or any valid
	// AWS service principal such as "sns.amazonaws.com". For example, you might
	// want to allow a custom application in another AWS account to push events
	// to AWS Lambda by invoking your function.
	Principal *string `type:"string" required:"true"`

	// This is optional; however, when granting Amazon S3 permission to invoke your
	// function, you should specify this field with the bucket Amazon Resource Name
	// (ARN) as its value. This ensures that only events generated from the specified
	// bucket can invoke the function.
	//
	// If you add a permission for the Amazon S3 principal without providing the
	// source ARN, any AWS account that creates a mapping to your function ARN can
	// send events to invoke your Lambda function from Amazon S3.
	SourceARN *string `locationName:"SourceArn" type:"string"`

	// The AWS account ID (without a hyphen) of the source owner. If the SourceArn
	// identifies a bucket, then this is the bucket owner's account ID. You can
	// use this additional condition to ensure the bucket you specify is owned by
	// a specific account (it is possible the bucket owner deleted the bucket and
	// some other AWS account created the bucket). You can also use this condition
	// to specify all sources (that is, you don't specify the SourceArn) owned by
	// a specific account.
	SourceAccount *string `type:"string"`

	// A unique statement identifier.
	StatementID *string `locationName:"StatementId" type:"string" required:"true"`
	// contains filtered or unexported fields

	// contains filtered or unexported fields
}

type CreateEventSourceMappingInput 

type CreateEventSourceMappingInput struct {

	BatchSize *int64 `type:"integer"`

	// Indicates whether AWS Lambda should begin polling the event source.
	Enabled *bool `type:"boolean"`

	// The Amazon Resource Name (ARN) of the Amazon Kinesis or the Amazon DynamoDB
	// stream that is the event source. Any record added to this stream could cause
	// AWS Lambda to invoke your Lambda function, it depends on the BatchSize. AWS
	// Lambda POSTs the Amazon Kinesis event, containing records, to your Lambda
	// function as JSON.
	EventSourceARN *string `locationName:"EventSourceArn" type:"string" required:"true"`

	// The Lambda function to invoke when AWS Lambda detects an event on the stream.
	//
	//  You can specify an unqualified 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 only the account ID qualifier (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 character in length.
	FunctionName *string `type:"string" required:"true"`

	// The position in the stream where AWS Lambda should start reading. For more
	// information, go to ShardIteratorType (http://docs.aws.amazon.com/kinesis/latest/APIReference/API_GetShardIterator.html#Kinesis-GetShardIterator-request-ShardIteratorType)

	// AWS Lambda also allows you to specify only the account ID qualifier (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

	// function. The default value is 128 MB. The value must be a multiple of 64
	// MB.
	MemorySize *int64 `type:"integer"`

	// The Amazon Resource Name (ARN) of the IAM role that Lambda assumes when it

type Lambda 

type Lambda struct {
	*aws.Service
}

Lambda is a client for AWS Lambda.

func New 

func New(config *aws.Config) *Lambda

New returns a new Lambda client.

func (*Lambda) AddPermission 

func (c *Lambda) AddPermission(input *AddPermissionInput) (*AddPermissionOutput, error)

Adds a permission to the access policy associated with the specified AWS Lambda function. In a "push event" model, the access policy attached to the Lambda function grants Amazon S3 or a user application permission for the Lambda lambda:Invoke action. For information about the push model, see AWS Lambda: How it Works (http://docs.aws.amazon.com/lambda/latest/dg/lambda-introduction.html). Each Lambda function has one access policy associated with it. You can use the AddPermission API to add a permission to the policy. You have one access policy but it can have multiple permission statements.

This operation requires permission for the lambda:AddPermission action.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/awserr"
	"github.com/aws/aws-sdk-go/aws/awsutil"
	"github.com/aws/aws-sdk-go/service/lambda"
)

		FunctionName:  aws.String("FunctionName"), // Required
		Principal:     aws.String("Principal"),    // Required
		StatementID:   aws.String("StatementId"),  // Required
		SourceARN:     aws.String("Arn"),
		SourceAccount: aws.String("SourceOwner"),
	}
	resp, err := svc.AddPermission(params)

	if err != nil {
		if awsErr, ok := err.(awserr.Error); ok {
			// Generic AWS Error with Code, Message, and original error (if any)
			fmt.Println(awsErr.Code(), awsErr.Message(), awsErr.OrigErr())
			if reqErr, ok := err.(awserr.RequestFailure); ok {
				// A service error occurred
				fmt.Println(reqErr.Code(), reqErr.Message(), reqErr.StatusCode(), reqErr.RequestID())
			}
		} else {
			// This case should never be hit, the SDK should always return an
			// error which satisfies the awserr.Error interface.
			fmt.Println(err.Error())
		}
	}

	// Pretty-print the response data.
	fmt.Println(awsutil.StringValue(resp))
}

Output:

func (*Lambda) AddPermissionRequest 

func (c *Lambda) AddPermissionRequest(input *AddPermissionInput) (req *aws.Request, output *AddPermissionOutput)

AddPermissionRequest generates a request for the AddPermission operation.

func (*Lambda) CreateEventSourceMapping 

func (c *Lambda) CreateEventSourceMapping(input *CreateEventSourceMappingInput) (*EventSourceMappingConfiguration, error)

Identifies a stream as an event source for a Lambda function. It can be either an Amazon Kinesis stream or an Amazon DynamoDB stream. AWS Lambda invokes the specified function when records are posted to the stream.

This is the pull model, where AWS Lambda invokes the function. For more information, go to AWS Lambda: How it Works (http://docs.aws.amazon.com/lambda/latest/dg/lambda-introduction.html) in the AWS Lambda Developer Guide.

This association between an Amazon Kinesis stream and a Lambda function is called the event source mapping. You provide the configuration information (for example, which stream to read from and which Lambda function to invoke) for the event source mapping in the request body. 

Each event source, such as an Amazon Kinesis or a DynamoDB stream, can

be associated with multiple AWS Lambda function. A given Lambda function can be associated with multiple AWS event sources.

This operation requires permission for the lambda:CreateEventSourceMapping action.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/awserr"

			fmt.Println(err.Error())
		}
	}

	// Pretty-print the response data.

}

Output:

func (*Lambda) CreateEventSourceMappingRequest 

func (c *Lambda) CreateEventSourceMappingRequest(input *CreateEventSourceMappingInput) (req *aws.Request, output *EventSourceMappingConfiguration)

CreateEventSourceMappingRequest generates a request for the CreateEventSourceMapping operation.

func (*Lambda) CreateFunction 

func (c *Lambda) CreateFunction(input *CreateFunctionInput) (*FunctionConfiguration, error)

Creates a new Lambda function. The function metadata is created from the request parameters, and the code for the function is provided by a .zip file in the request body. If the function name already exists, the operation will fail. Note that the function name is case-sensitive.

This operation requires permission for the lambda:CreateFunction action.
