NetBackup API call format works in Unix but not Windows

I am running NetBackup 8.2 on a Solaris master. I am writing a script to run on my existing Windows clients for when the server needs to be reinstalled and it needs to have a re-issue token to allow automated installation of the NetBackup software. I have a working version of the script for Linux but I am having an issue converting it to run as a PowerShell script. I have been able to convert all the other API calls but not  the POST /security/securitytokens to create the new token. If I use the autogenerate API GUI when connecting to https://MASTER/api-docs/index.html in the security section it will only produce a Unix curl version. I even created a test Windows master server and it also only generates a Unix curl formatted output. I have checked the github site but I could not find a PowerShell example of this API command 

The generated code obtained is as follows:

curl -X POST "https://MASTER/netbackup/security/securitytokens" -H "accept: application/vnd.netbackup+json;version=3.0" -H "Authorization: ABCDEFGHIJKLMNOPQRSTUVWXYZ" -H "Content-Type: application/vnd.netbackup+json;version=3.0" -d "{ \"tokenName\": \"test1\", \"hostId\": \"testid\", \"reason\": \"Re-Issue\", \"allowedCount\": 1, \"validFor\": 3600, \"type\": 1}"

I had to change curl to curl.exe to use the true curl program not the alias to Invoke-WebRequest (which format is completely different) and add the -k option. This will produce the following error:

{"errorCode":9926,"errorMessage":"Input JSON is invalid","attributeErrors":{},"fileUploadErrors":[],"errorDetails":[]}

I have tried replacing the \" with ^" and also ' instead of \" but still get the JSON invalid message. 

Is there an option or any way to generate the output for Windows PowerShell? 

Any help will be greatly appreciated.

Thank you.

Re: NetBackup API call format works in Unix but not Windows

So I was finally able to resolve this issue by using the builtin Invoke-WebRequest command. Here is the syntax that I used (Note - auth_header, tokenName and hostId were defined earlier in the script):

$basepath="https://" + $NBU_master + "/netbackup/"

$uri = $basepath + "security/securitytokens"

$reason = "Re-Install"

$allowedCount = 1

$validFor = 3600

$reissue_token = 1

 

$type = @{

tokenName=$tokenName

hostId=$hostId

reason=$reason

allowedCount=$allowedCount

validFor=$validFor

type=$reissue_token

}

 

$response = Invoke-WebRequest `

-Headers $auth_header `

-Method POST `

-Uri $uri `

-Body (ConvertTo-Json -InputObject $type) `

-ContentType $content_header_3

 

$convert = (ConvertFrom-Json -InputObject $response)

$tokenValue=$convert.tokenValue

 

Thank you for your help.

Re: NetBackup API call format works in Unix but not Windows

you may want to change the "-d" to a "--data-urlencode" and then urlencode the data so that you don't have to escape the slashes...

Try something like (I've not tested it, but it will help you look in the right direction...)

curl -X POST "https://MASTER/netbackup/security/securitytokens" -H "accept: application/vnd.netbackup+json;version=3.0" -H "Authorization: ABCDEFGHIJKLMNOPQRSTUVWXYZ" -H "Content-Type: application/vnd.netbackup+json;version=3.0" --data-urlencode "%7B%20%22tokenName%22%3A%20%22test1%22%2C%20%22hostId%22%3A%20%22testid%22%2C%20%22reason%22%3A%20%22Re-Issue%22%2C%20%22allowedCount%22%3A%201%2C%20%22validFor%22%3A%203600%2C%20%22type%22%3A%201%7D"

Re: NetBackup API call format works in Unix but not Windows

Thank you for your response. I tried your suggestion but I am still getting the Input JSON is invalid. I ran the curl with the -v option to give some additional output:

curl.exe -v -k POST "https://MASTER/netbackup/security/securitytokens" -H "accept: application/vnd.netbackup+json;version=3.0" -H "Authorization: ABCDEFGHIJKLMNOPQRSTUVWXYZ" -H "Content-Type: application/vnd.netbackup+json;version=3.0" --data-urlencode "%7B%20%22tokenName%22%3A%20%22test1%22%2C%20%22hostId%22%3A%20%22testid%22%2C%20%22reason%22%3A%20%22Re-Issue%22%2C%20%22allowedCount%22%3A%201%2C%20%22validFor%22%3A%203600%2C%20%22type%22%3A%201%7D"

Re: NetBackup API call format works in Unix but not Windows

I did say that I hadn't tested it...

The key thing is that by using the "--data-urlencode" option you can focus on getting the json right and not worry about escaping "quotes" etc....

I encoded it using this site https://www.urlencoder.org/

I would start by going back to the curl command that you could run on linux, and check that the json string is the same.  

Did it use single quotes???


Share the command that works for unix, we can try and verify what string you need to pass...
