[FIXED] Trigger parameterized build with curl and crumb

Issue

I've seen similar posts to this on SO, but not quite exactly what I am trying to do (or at least no full examples of a command to run).

I am trying to remotely trigger a parameterized build on Jenkins using curl. I have 'Prevent Cross Site Request Forgery' enabled so I also need to pass a valid crumb.

The script I have is below:

#!/bin/bash

json="{\"parameter\": [{ \"P1\": \"param1\", \"P2\": \"param2\", \"P3\": \"param3\" }]}"
crumb=`curl "http://SERVER/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,%22:%22,//crumb)"`

curl -v -H $crumb -X POST http://SERVER/job/JOB_NAME/buildWithParameters -d token=runme --data-urlencode json="$json"

I've also tried modifying the URL I'm passing to curl to either:

USERNAME:APITOKEN@SERVER

and

USERNAME:PASSWORD@SERVER

Output from curl is:

* About to connect() to SERVER port 8080 (#0)
*   Trying SERVER... connected
* Connected to SERVER (SERVER) port 8080 (#0)
* Server auth using Basic with user 'USERNAME'

> Host: SERVER:8080

So it looks like I'm not passing the crumb properly, but I'm not sure what the correct format of the command should be.

Solution

The correct format is as follows:

curl -H ".crumb:xxxxxxxxxxxxxxxxxxxxxx"
