A HTTP tracing tool, created after re-visiting this Stack Overflow question one too many times. Send a HTTP request, get the response and a trace report back.
Heavily based off rakyll/hey which is fantastic and highly recommended if you need a tool to send load to a web server.
Usage: http-trace [options...] <url>
Options:
-H
HTTP headers to send with the request
-d
The HTTP request body data
-m
The HTTP method to use (default "GET")
-suppress-body
Suppress the response body in the output
-suppress-headers
Suppress the response headers in the output
-t
Timeout for the HTTP request in seconds (default 5)
Send a GET request to https://pkg.go.dev/net/http/httptrace, add a couple of headers, and suppress the response headers and body from the output:
http-trace -m GET -suppress-headers -suppress-body -H 'X-One: hello' -H 'X-Two: one two three' https://pkg.go.dev/net/http/httptraceThe output of that command would look like this:
> GET pkg.go.dev/net/http/httptrace HTTP/1.1
> X-One: hello
> X-Two: one two three
>
< 200 OK
