fasthttpadaptor

This package contains a fork of https://github.com/valyala/fasthttp/tree/v1.41.0/fasthttpadaptor with some Dapr-specific changes.

These changes are only needed to support the hybrid state in which Dapr's HTTP server is using fasthttp, and the HTTP channel (and its middlewares) are using net/http. This package will be obsolete when #4979 is addressed.

Overview

Package fasthttpadaptor provides helper functions for converting net/http request handlers to fasthttp request handlers.

  • func (w *NetHTTPResponseWriter) WriteHeader(statusCode int)

Functions

func ConvertRequest

func ConvertRequest(ctx *fasthttp.RequestCtx, r *http.Request, forServer bool) error

ConvertRequest converts a fasthttp.Request to an http.Request. forServer should be set to true when the http.Request is going to passed to a http.Handler.

The http.Request must not be used after the fasthttp handler has returned! Memory in use by the http.Request will be reused after your handler has returned!

func NewFastHTTPHandler

func NewFastHTTPHandler(h http.Handler) fasthttp.RequestHandler

NewFastHTTPHandler wraps net/http handler to fasthttp request handler, so it can be passed to fasthttp server.

While this function may be used for easy switching from net/http to fasthttp, it has the following drawbacks comparing to using manually written fasthttp request handler:

• A lot of useful functionality provided by fasthttp is missing from net/http handler.
• net/http -> fasthttp handler conversion has some overhead, so the returned handler will be always slower than manually written fasthttp handler.

So it is advisable using this function only for quick net/http -> fasthttp switching. Then manually convert net/http handlers to fasthttp handlers according to https://github.com/valyala/fasthttp#switching-from-nethttp-to-fasthttp .

func NewFastHTTPHandlerFunc

func NewFastHTTPHandlerFunc(h http.HandlerFunc) fasthttp.RequestHandler

NewFastHTTPHandlerFunc wraps net/http handler func to fasthttp request handler, so it can be passed to fasthttp server.

While this function may be used for easy switching from net/http to fasthttp, it has the following drawbacks comparing to using manually written fasthttp request handler:
