Node-Casbin bug

我用两个 in 操作 && 串联起来，如果是 true && true , 实际得到的结果是 false, 这个是什么问题呀？

将 多个 in 拆成单独的 matchers 是正常的，&& 起来就非预期了.

const fs = require ('fs') const path = require ('path') const Casbin = require ('casbin')

const model1Text = `request_definition r = sub, obj, act

policy_definition p = sub, obj, act

policy_effect e = some (where (p.eft == allow))

matchers m = r.act in "('In', 'Out')"`

const model2Text = `request_definition r = sub, obj, act

policy_definition p = sub, obj, act

policy_effect e = some (where (p.eft == allow))

matchers m = r.sub in "('root', 'guest')"`

const model3Text = `request_definition r = sub, obj, act

policy_definition p = sub, obj, act

policy_effect e = some (where (p.eft == allow))

matchers m = r.act in "('In', 'Out')" && r.sub in "('root', 'guest')"` ; (async () => { //initial models const path1 = path.resolve (dirname, './model1.conf') const path2 = path.resolve (dirname, './model2.conf') const path3 = path.resolve (__dirname, './model3.conf') fs.writeFileSync (path1, model1Text) fs.writeFileSync (path2, model2Text) fs.writeFileSync (path3, model3Text)

//loading enforcer const enforcer1 = await Casbin.newEnforcer (path1) const enforcer2 = await Casbin.newEnforcer (path2) const enforcer3 = await Casbin.newEnforcer (path3)

//test const result1 = await enforcer1.enforce ('root', {}, 'In') const result2 = await enforcer2.enforce ('root', {}, 'In') const result3 = await enforcer3.enforce ('root', {}, 'In') console.log ('result1 : ', result1) //true console.log ('result2 : ', result2) //true console.log ('result3 : ', result3) //false })();
