I'll recommend using wrk2
instead of wrk
since wrk2 provides better support for concurrent requests. When content-type
header is application/json
then please escape the special characters like \n
with \\n
and all other special characters present. Not doing this will send an invalid json to the upstream API, which will waste your time debugging.
Create a file with extension lua
and paste the following in it. Save it and pass it along with -s
flag to wrk2 command.
wrk.method = "POST"
wrk.body = "{\"firstKey\": 'somedata', \"secondKey\": 'somedata'}"
wrk.headers["Content-Type"] = "application/json"
Also you can add multiple header as
wrk.headers["Header1"] = "Header1_Val"
wrk.headers["Header2"] = "Header2_Val"
wrk.headers["Header3"] = "Header3_Val"
wrk.headers["Header4"] = "Header4_Val"
