getting error, but command works for changing server power state

[BradV]

The command is working, but I am getting a parse error: Invalid numeric literal at line 1, column 9

DATA='{"powerState":"Off","powerControl":"MomentaryPress"}'
curl --insecure \
       --header "content-type: application/json" \
       --header "X-API-Version: ${currentVersion}" \
       --header "auth: ${sessionID}" \
       --include \
       --data "${DATA}" \
       --request PUT ${OneView}/rest/server-hardware/{id}/powerState | jq -r '.'

The server is powering off, but I'm getting that error.  If I change the powerState to On and apply, that works also, but with the same parse error.  Anyone have a clue what could be wrong?

This is an error within Bash, and your use of jq.  I found a thread on this over on Stackoverflow.  The HTTP response from this request will be either an HTTP Error (400-, 500- series code) or HTTP 202 for success.  There will be no JSON response until you get the Location HTTP header for the async task from the HTTP 202 response.  Otherwise, what are you trying to parse with jq in your pipeline?

Hi Chris,

I have no idea. 

It's my standard response when sending a command to the REST API.  I'll remove it and see what messages I'm receiving.  It is working.  So, that part is good.

Thanks!

I'm no Bash expert, but I can't see why one would use jq here when the reply doesn't include a JSON reply. If it did, and you wanted to parse the response, then it could be used.

No, totally my fault.  I did not look at the specs close enough to notice it was not a json output.  Sorry!

I fixed with:

DATA='{"powerState":"Off","powerControl":"MomentaryPress"}'
TASKURI=$(curl --insecure \
       --header "content-type: application/json" \
       --header "X-API-Version: ${currentVersion}" \
       --header "auth: ${sessionID}" \
       --include \
       --data "${DATA}" \
       --request PUT ${OneView}/rest/server-hardware/{id}/powerState |  grep '^Location:' | awk '{ print $2})

Can then check the status of the task with:

curl --insecure \
       --header "X-API-Version: ${currentVersion}" \
       --header "auth: ${sessionID}" \
       --request GET ${OneView}${TASKURI} | jq -r '.'
