send advanced http request and capture response using wrk/wrk2 about wrk2

[wandenberg]

@suni1mp and @GrayedFox you can write a lua script and configure the wrk.body and wrk.headers.
something like

wrk.headers["Content-Type"] = "application/json"
wrk.body = '{"my":"json"}'

or in a dynamic way

request = function()
wrk.format(method, path, headers, body)
    -- you can create the values dynamically here using lua
    return wrk.format('POST','/resource/path', {["Content-Type"]= "application/json"}, '{"my":"json"}')
end

I got this information from here
It also recommends for performance to create your requests first if they have a lot of logic.

Thanks man will give that a go when I'm next doing some stress testing

@wandenberg should {"Content-Type": "application/json"} actually be {["Content-Type"]= "application/json"}?

[wandenberg]

Correct @rex-remind101
Thanks for noticing. I edited the example to make it easier.
