Invoking the /build endpoint for a job with curl dropping parameters not explicitly passed via json

[Jay Hayes]

Hello,

This seems like a bug to me but, if so, I don't know how it hasn't been reported which makes me think I'm overlooking something obvious.

When I invoke a jenkins job via curl and send the parameters as JSON data\payload to the job's /build endpoint any parameters I don't pass in the payload disappear from the invoked build for that job (even if the parameters omitted have default values).

For instance, say I have a job test-job with the following parameters defined:

String Parameter
	Name
	Default Value
	Description	[Safe HTML] Preview
		Trim the string
Delete

String Parameter
	Name
	Default Value
	Description	[Safe HTML] Preview

If i invoke said job via curl using the /build endpoint:

curl --location --request POST 'http://XXXXXXXXXXXXXXX:8080/job/test-job/build' \

--header 'Content-Type: application/x-www-form-urlencoded' \

--header 'Authorization: XXXXXXXXXXXXXXXXXXXXXXX' \

--data-urlencode 'json={"parameter":[{"name":"required_param","value":"myValue"}]}'

The default_param is dropped entirely from the resultant build:

Build #8

Parameters

	required_param

Instead if I invoke the job via curl with url query params using the /buildWithParameters endpoint it works as I would expect:

curl --location --request POST 'http://XXXXXXXXXXXXXXX:8080/job/test-job/buildWithParameters?required_param=myValue' \

--header 'Content-Type: application/x-www-form-urlencoded' \

--header 'Authorization: XXXXXXXXXXXXXXXXXXXXXXX'

Build #9

Parameters

	required_param
	default_param

Is there a bug with the /build endpoint WRT passing parameters as json data?

Thanks,

Jay

I suspect that is intentional.  I assume that the '/build' end point is not intended for use with parameters.  If you want to pass parameters, use the /buildWithParameters end point.

Fair enough but, for whatever reason, I can only get the parameters passed as JSON data when I use the /build endpoint.  If I POST to the /buildWithParameters endpoint, all parameters show up in the invoked build but with no values (other than defaults).

Using the same example with the following curl:

curl --location --request POST 'http://XXXXXXXXXXXXXXXXXXX:8080/job/test-job/buildWithParameters' \

--header 'Content-Type: application/x-www-form-urlencoded' \

--header 'Authorization: XXXXXXXXXXXXXXXXXXXXX' \

--data-urlencode 'json={"parameter":[{"name":"required_param","value":"myValue"}]}'

Yields:

Build #11

Parameters

	required_param
	default_param

The default_param is now included with the correct default value but the value passed for the required_param is missing?

Hai.. I need to send the whole json string to the jenkin's parameter. Do u have any idea how to do that.
