SOrry, I've not understood how to set environnmental variables to print out the body of my post requests
Hello! Thank you for this project.
I used it for comparing different requests I was making from vanilla fetch
API and through a proxy service I do not have direct control over.
The problem I faced with was a CORS, because I worked with Electron-based app (which is a browser under the hood):
Access to fetch at 'http://localhost:8080/' from origin 'app://obsidian.md' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
To fix the error I've added the following line to serveHTTP
:
wr.Header().Set("Access-Control-Allow-Origin", "*")
wr.Header().Set("Access-Control-Allow-Methods", "*")
wr.Header().Set("Access-Control-Allow-Headers", "*")
Consider adding those headers with an option you can configure on startup.
Thanks for making this! This might be obvious, but I was confused at first when PORT
by itself didn't work for me, but adding --publish
fixed it. Maybe an example in the README of the correct usage?
$ docker run --detach -P -e PORT=80 --name echo1 jmalloc/echo-server
$ docker logs echo1
Echo server listening on port 80.

I noticed that the latest tag has a different architecture then the previous. This change breaks thing in a project i am working on. Was this intentional?
The server sends an unsolicited initial WebSocket message
echo-server/cmd/echo-server/main.go
Lines 106 to 113 in b9eb3f7
Would you be open to add an option to skip it?
Refs: markthethomas/ws-echo#1
wss from generated self signed cert/key or from mount folder with cert/key
Would you feel comfortable having version tags on DockerHub, in addition to latest? I don't expect the behavior will change radically, but I'm a bit more comfortable if dependencies are pinned.
In
echo-server/cmd/echo-server/main.go
Line 254 in 695e6e6
HTTP-Version Method Request-URI
, while the RFC https://www.rfc-editor.org/rfc/rfc2616#section-5.1 states it is Method Request-URI HTTP-Version
This confused me as I thought the reverse proxy I was trying to debug was mangling the request.
I realised when looking at the code that the line needs to be re-created from the request. I think it should be rebuilt in the expected order.
How do you open a shell?
kubectl exec -ti POD /bin/bash
does not work
I don't see any headers get output
eg:
# start
PORT=8080 APP_ROOT=/app echo-server
# access
curl localhost:8080/app/
Thx.
This would be similar to the existing LOG_HTTP_BODY environment variable.
The server should support serving HTTPS/WSS using a configurable cert chain. If no such configuration is provided it should generate a self-signed certificate on-the-fly.
Hi.
I am using your echo server (wss://ws.ifelse.io/) as a test to check my library for web-socket connection. The language is C# and I use .Net Framework 4.5 platform (there is some requirement to use deprecated stack). Internally I use ClientWebSocket and all works fine from my local PC.
But, as I call the same (just establish websocket connection ) from the GitHub workflow (I have some simple CI test automation on GutHub) I got the following error:
System.Exception: At method OpenConnection was occured exeption:The server returned status code '403' when status code '101' was expected.
I can't have any idea of what causing this behaviour. I looked at the source code and didn't find any that could cause this. So maybe any suggestions or ideas I would give here. Thanks
Hi ๐๐ผ In order to combat dockerhub's imposed rate limits it would be great to host these images on GHCR.
Push echo-server to an additional registry like GHCR
Thanks!
