Example of using Apache Bench (ab) to POST JSON to an API

cmd.sh

# post_loc.txt contains the json you want to post
# -p means to POST it
# -H adds an Auth header (could be Basic or Token)
# -T sets the Content-Type
# -c is concurrent clients
# -n is the number of requests to run in the test

ab -p post_loc.txt -T application/json -H 'Authorization: Token abcd1234' -c 10 -n 2000 http://example.com/api/v1/locations/

can someone share the actual post_loc.txt file. This command does not work with the json file used to post json data ?

I get Error : Could not stat POST data file (content.json/content.txt): Partial results are valid but processing is incomplete

Do we first need to write JSON data to the file post_loc.txt ? If the above code works, share the code to write JSON data to text file in command prompt.

Yeah~it's just JSON data in the file.
something like {"userid": XXX,"appid": "XXX","option": "XXX"}

Hai kinger310,
Do we need to specify the location of the same?What is its format ? (For example: D:/apacheload/post_loc.txt)

How we can pass parameters? along with url / in a separate format in this command?

I got the result ( different metrics to understand the various output values returned by ab) when I use the above with slight change. The command line statement should look like this : For example:

First install apache sever,then open bin folder inside apache,open command prompt and type the command as given below

ab -p C:\Users\Dell\Desktop\ab\smartinvoice.txt -T application/json -H '1ef632f7-02fe-41cd-beec-a1f9bb8cae03' -c 100 -n 1000 http://localhost:3036/app/smartinvoice/document/smartinvoice

where,
path of the text file --> C:\Users\Dell\Desktop\ab\smartinvoice.txt
URI path --> http://localhost:3036/app/smartinvoice/document/smartinvoice
token (different for each login) --> '1ef632f7-02fe-41cd-beec-a1f9bb8cae03'

The output is as follows:

Give small values for c and n. Then increase these values until we get failure cases to see different cases.

But records are not saved in the db.
If any one get the result..pls post here

Is it possible to store data from text file(in our post_loc.txt) into db using apache benchmarking command mentioned below:

ab -p post_loc.txt -T application/json -H 'Authorization: Token abcd1234' -c 10 -n 2000 http://example.com/api/v1/locations/

Do we need to specify db name or db related information to store json data in the text file ?

JSON data in the text file not saved into db. but it shows metrics in the output.Anyone knows about this issue? How to solve ?

I trying to replicate this example but I always get:

ab: Could not stat POST data file (data.txt): Partial results are valid but processing is incomplete. I can't see the problem, any idea?

NICE

Can Apache bench support dyamic values in post request ?

Thanks for sharing.

can someone share the actual post_loc.txt file. This command does not work with the json file used to post json data ?

I get Error : Could not stat POST data file (content.json/content.txt): Partial results are valid but processing is incomplete

This means it's unable to find the POST data file. specify the absolute path

Can Apache bench support dynamic values in post request ?

I have the same need .

According to this Changing POST data used by Apache Bench per iteration .

Maybe more specialized tool like Jmeter is a better option.
