julb/http-reqtrace repository overview
http-reqtrace
Description
The application starts a Web server which logs details of all incoming HTTP requests such as:
- HTTP Method & URL
- Query params
- Headers
- Body
The application accepts all HTTP methods and URIs. The routing is defined like this:
/status/:statusCode: return an HTTP response with status code statusCode and body{"message":"OK|KO"}/**/*: return an HTTP response with status code 200 OK and body{"message":"OK"}/metrics: return Prometheus metrics regarding HTTP requests
Following query parameters are also supported:
?latencyInMs=60000: wait for the given period in milliseconds before responding. This time cannot exceed 5 minuts.
This service can be used to :
- See very quickly what are the requests received and inspect their content.
- Have a quick way to simulate specific cases with particular HTTP response codes.
How to use
Starts the service
- Run container as root:
$ docker run -ti --name http-reqtrace -p 80:80 julb/http-reqtrace:latest
- Run container as non-root:
$ docker run -ti --name http-reqtrace -p 80:8080 -e PORT=8080 -u 65534:65534 julb/http-reqtrace:latest
Note: the PORT environment variable can be set to customize listening port.
Request the service with any method, URI and parameters
$ curl http://localhost/context/uri?param1=value1¶m2=value2 -H "Authorization: Bearer jwt"
{"statusCode": 200,"message":"OK"}
