Command-line Tools

Casbin CLIs expose the Casbin API from the command line so you can load models and policies, run enforce checks, and manage policy from your shell. Implementations are available for Go, Java, Node.js, Python, .NET, and Rust.

Erste Schritte

• Verify if Alice can read data1:

  ./casbin enforce -m "examples/rbac_model.conf" -p "examples/rbac_policy.csv" "alice" "data1" "read"

  {"allow":true,"explain":null}

  ./casbin enforce -m "[request_definition]\nr = sub, obj, act\n[policy_definition]\np = sub, obj, act\n[role_definition]\ng = _, _\n[policy_effect]\ne = some(where (p.eft == allow))\n[matchers]\nm = g(r.sub, p.sub) && r.obj == p.obj && r.act == p.act" -p "p, alice, data1, read\np, bob, data2, write\np, data2_admin, data2, read\np, data2_admin, data2, write\ng, alice, data2_admin" "alice" "data1" "read"

  {"allow":true,"explain":null}

• Verify if Alice can write to data2 and show which policy grants the permission:

  ./casbin enforceEx -m "examples/rbac_model.conf" -p "examples/rbac_policy.csv" "alice" "data2" "write"

  {"allow":true,"explain":["data2_admin","data2","write"]}

• Add a new policy rule to the policy file (casbin-java-cli only):

  ./casbin addPolicy -m "examples/rbac_model.conf" -p "examples/rbac_policy.csv" "alice" "data2" "write"

  {"allow":true,"explain":null}

• Remove a policy rule from the policy file (casbin-java-cli only):

  ./casbin removePolicy -m "examples/rbac_model.conf" -p "examples/rbac_policy.csv" "alice" "data2" "write"

  {"allow":true,"explain":null}
