How to execute POST - load-testing

Question

Using curl I have:
$ curl -v -d "userName=user1&password=passwd1&language=en" http://myhost:23094/api/v2/authToken
...
> POST /api/v2/authToken HTTP/1.1
> User-Agent: curl/7.30.0
> Host: myhost:23094
> Accept: */*
> Content-Length: 39
> Content-Type: application/x-www-form-urlencoded
>
* upload completely sent off: 39 out of 39 bytes
< HTTP/1.1 200 OK
I try to build a yandex tank script using this query:
My load.ini:
[phantom]
address=my.ip.v4.here
port=8094
rps_schedule=line(1, 10, 1m)
ammo_type=uripost
My ammo.txt
133 login
POST /api/v2/authToken HTTP/1.1
User-Agent: tank
Host: somemyhost.com
Content-Length: 39
userName=user1&password=passwd1&language=en
When I run yandex-tank ammo.txt, I get the 400 Bad Request error.
It seems to me, that tank can't use the body parameters. How to make it use them? What do I do wrong?

Answer 1

Your ammo is not in uripost format. Don't specify ammo_type at all and it should work properly. If you want to use uripost format, specify your headers in load.ini and write something like the following in your ammo file:
39 /api/v2/authToken login
userName=user1&password=passwd1&language=en
Here is the description of the uripost format.
