Hi,

I try to reach the jenkins script console using a curl command on Windows CMD, because I want to give Jenkins through the script console commands from outside to execute.

But when I try this I always get error messages like this:

curl: (3) URL rejected: Bad hostname
curl: (3) URL rejected: Bad hostname
curl: (6) Could not resolve host: default-src
curl: (3) URL rejected: Bad hostname
curl: (6) Could not resolve host: img-src
curl: (3) URL rejected: Bad hostname
curl: (3) URL rejected: Port number was not a decimal number between 0 and 65535
curl: (3) URL rejected: Bad hostname

The command I use is:

curl -d "script=<System.setProperty("hudson.model.DirectoryBrowserSupport.CSP","sandbox allow-scripts; default-src 'none'; img-src 'self' data: ; style-src 'self' 'unsafe-inline' data: ; script-src 'self' 'unsafe-inline' 'unsafe-eval' ;")>" http://192.XXX.XX.XXX:8080/script

In this case I want to integrate this command in a startup script to get this JavaScript error message when trying to open .html or .xml reports and logs and so on.

I tried a lot workarounds I’ve found on the entire internet, but no one fixed this JavaScript issue. Thats why I want to try to use this curl command workaround on start up to fix it. Or do you have any ideas how to solve this problem in another way?

Hope someone could help me and would be very thankful.

Check Groovy Hook Scripts how to create an init groovy script
Note that you shouldn’t set a system property for what you want to achieve, but just use

hudson.model.DirectoryBrowserSupport.CSP="sandbox allow-scripts; default-src 'none'; img-src 'self' data: ; style-src 'self' 'unsafe-inline' data: ; script-src 'self' 'unsafe-inline' 'unsafe-eval'"

in the groovy script.

Thanks for your solution on this :slight_smile: ! Unfortunately it doesn’t work, Created an init.groovy script, gave execute permission, putted in your command line, placed it at path “/var/lib/jenkins” and restarted Jenkins, but didn’t have any effect.

You need to get your quoting right, your first string ends t ...(" You need to escape the inner quotes, possibly multiple times.

And you need to authenticate the call most probably anyway.

Thank you! But normally quoting should be okay. Just used the Jenkins script console command surrounded by the curl command. And would’t escaping be needed in other szenarios? Or what did you mean exactly?
