Overview ¶
Package lambdaurl serves requests from Lambda Function URLs using http.Handler.
This package allows you to use standard Go http.Handler implementations with Lambda Function URLs, making it easy to adapt existing HTTP applications to run on Lambda.

Functions ¶
func RequestFromContext ¶
func RequestFromContext(ctx context.Context) (*events.LambdaFunctionURLRequest, bool)
RequestFromContext returns the *events.LambdaFunctionURLRequest from a context.
func Start ¶
Start wraps a http.Handler and calls lambda.StartHandlerFunc Only supports:
- Lambda Function URLs configured with `InvokeMode: RESPONSE_STREAM`
- Lambda Functions using the `provided` or `provided.al2` runtimes.
- Lambda Functions using the `go1.x` runtime when compiled with `-tags lambda.norpc`
func WithDetectContentType ¶ added in v1.42.0
WithDetectContentType sets the behavior of content type detection when the Content-Type header is not already provided. When true, the first Write call will pass the intial bytes to http.DetectContentType. When false, and if no Content-Type is provided, no Content-Type will be sent back to Lambda, and the Lambda Function URL will fallback to it's default.
Note: The http.ResponseWriter passed to the handler is unbuffered. This may result in different Content-Type headers in the Function URL response when compared to http.ListenAndServe.
Usage:
lambdaurl.Start(
http.HandlerFunc(func (w http.ResponseWriter, r *http.Request) {
w.Write("<!DOCTYPE html><html></html>")
}),
lambdaurl.WithDetectContentType(true)
)
func Wrap ¶
func Wrap(handler http.Handler) func(context.Context, *events.LambdaFunctionURLRequest) (*events.LambdaFunctionURLStreamingResponse, error)
Wrap converts an http.Handler into a Lambda request handler.
Only Lambda Function URLs configured with `InvokeMode: RESPONSE_STREAM` are supported with the returned handler. The response body of the handler will conform to the content-type `application/vnd.awslambda.http-integration-response`.
