Echo server

HTTP echo server, that's it.

Installation

cargo install echo-server

Usage

Defaults:

• HTTP server listens to 0.0.0.0:8080.
• HTTP request headers return with the response.
• GET requests have no body content.

echo-server [-p|--port=8080]

All HTTP verbs are supported.

Configuration options

Set static response body.

echo server [-b|--body="Custom GET response body"] 

Set (repeated) static response headers key:value pairs.

echo server [-h|--header="key1:value1"] [-h|--header="key2:value2"]

GET request

curl -vvv -X GET localhost:8080
curl -vvv -X GET -H "x-random-header: test" localhost:8080

POST request

curl -vvv -X POST -H "Content-Type: application/json" -d '{"hello": "world"}' localhost:8080

Docker

You can run a precompiled image from Docker hub:

docker run --rm -p 8080:8080 --name echo swaagie/echo-server:latest

Or build the image local:

docker build -t echo-server .
docker run --rm -p 8080:8080 --name echo echo-server

Listen on a different port:

docker run --rm -p 8081:8081 --name echo echo-server --port=8081
