Adding the trailing slash allows to trigger the bench handler for performance measurements in situations where a trailing slash character '/' is added to the request. For example, in traefik addPrefix middleware, if you specify a "/bench" prefix, a request on "http://localhost" will be transformed from "GET /" to "GET /bench/" with no way to remove the trailing '/' (at least without adding another rewrite rule, which would modify measurements).
whoami
Tiny Go webserver that prints os information and HTTP request to output
Usage
Paths
/data?size=n[&unit=u]: creates a response with a sizen. The unit of measure, if specified, accepts the following values:KB,MB,GB,TB(optional, default: bytes)./echo: webSocket echo./bench: always return the same response (1)./[?wait=d]: returns the whoami information (request and network information). The optionalwaitquery parameter can be provided to tell the server to wait before sending the response. The duration is expected in Go'stime.Durationformat (e.g./?wait=100msto wait 100 milliseconds)./api: returns the whoami information as JSON./health: heath checkGET,HEAD, ...: returns a response with the status code defined by thePOSTPOST: changes the status code of theGET(HEAD, ...) response.
Flags
cert: give me a certificate.key: give me a key.port: give me a port number. (default: 80)name: give me a name. (it can be also defined withWHOAMI_NAMEenvironment variable)
