How to identify admins on Jenkins using groovy scripts

问题

I want to be able to check whether the current build user who is running the job is admin or not. I used some APIs to figure out the admins user list as shown below

import jenkins.model.Jenkins
import hudson.model.User
import hudson.security.Permission

allUsers = User.getAll()
adminList = []
for (u in allUsers) {
 if (u.hasPermission(Jenkins.ADMINISTER)) {
 // if (u.canDelete()) {
   adminList.add(u)
  }
}
println allUsers 
println adminList

but always both the list of users (admins and average-joes) are same, yes i am sure, not all users are admin in my jenkins server :)

回答1:

import jenkins.model.Jenkins
import hudson.model.User

allUsers = User.getAll()
adminList = []
authStrategy = Jenkins.instance.getAuthorizationStrategy()

for (u in allUsers) {
    if (authStrategy.hasPermission(u.toString(), Jenkins.ADMINISTER)) {
        adminList.add(u)
    }
}

println(adminList)
