Logserver

Simple service for logging all incoming requests

Install

As binary

go install github.com/negasus/logserver@latest

Or you can use docker image

docker pull negasus/logserver

Params

• -a or env variable LISTEN_ADDR for define listen address (default: :2000)
• -b or env variable RESPONSE_BODY for define response body (default: empty)
• -c or env variable RESPONSE_CODE for define response status code (default: 200)
• -t or env variable CONTENT_TYPE for define response content type header (default: empty)
• -f or env variable FILE_SERVER for define file server path (default: empty)

If you define the response body, \n will be replaced to new line separator, and \t will be replaced to tab

You can specify filename for response body. You should define response body as file://<filename_path>

If you use -f, you should not use -b, -c and -t params

Example:

# use /home/user/demo.json for response body

$ logserver -b file:///home/user/demo.json
