如何授权一名Solr用户使用一个Solr 7的内核

如何解决如何授权一名Solr用户使用一个Solr 7的内核

我想创建多个用户，每个用户可以访问一个或多个核心，我有两个核心[Solr_sample和name核心]我试图创建以下文件，但没有用

   "authentication":{
      "class":"solr.BasicAuthPlugin","blockUnkNown": true,"credentials":{
         "solr":"IV0EHq1OnNrj6gvRCwvFwTrZ1+z1oBbnQdiVC3otuq0= Ndd7LKvVBAaZIF0QAVi1ekcfAJXr1GGfLtRUXhgrF8c=","devuser":"IV0EHq1OnNrj6gvRCwvFwTrZ1+z1oBbnQdiVC3otuq0= Ndd7LKvVBAaZIF0QAVi1ekcfAJXr1GGfLtRUXhgrF8c="
      }
   },"authorization":{
      "class":"solr.RuleBasedAuthorizationPlugin","permissions":[
       {
            "name":"core-admin-read","path": "/admin/cores/Solr_sample/select?q=*:*","role":"admin"
         }
         
      ],"user-role":{
         "solr":"admin","devuser":"dev"
      }
   }
}
