httperf to test an json rest api

Question

I have a file with this content:

helper?token=99999 method=POST contents='{"key1":99999, "key2":88888, "key3":55}'

and then I run this command:

httperf --print-reply --print-request --hog --client=0/1 --server=a_server --port=8080 --uri=/ --rate=25 --send-buffer=4096 --recv-buffer=16384 --add-header='Content-Type:application/json' --method=POST --wsesslog=1,1.000,entrada_carga

But the server is not getting any json. I already tried different escape options without success.

And the same post with curl it works perfectly.

Do you have any pointer in posting json with httperf?

thanks in advance

Answer 1

You have to add an explicit carriege return to the end of the header, like this:

--add-header='Content-Type:application/json\n'

Answer 2

Example with header, post and ssl

httperf --server yourhost.com.com --uri /smartlog --num-conns=500 --rate=500 --ssl  --method POST --wsesslog=100000,0,httprefpost_data.txt --add-header "sdk:3.0\nconfig:3.0\nzid:0\n"

create file (httprefpost_data.txt) with below content:

/smartlog method=POST contents='data=testing&uid=13'

Answer 3

Use the following to break the URL into server and URI:

httperf --print-reply --print-request --server "hostname.com" --uri="rest of url"
