如何在Loopback ACL中使用静态角色进行身份验证

Question

在模型中使用静态角色访问控制进行身份验证时遇到问题。当使用ACL与主要类型$ authenticated和$ everyone时，事情似乎正在起作用。因此，登录和注销时，访问控制已就位并按预期运行。当ACL被移动到静态角色时，身份验证失败并返回401。正在使用内置于角色，角色映射和用户的模型的环回。我已经尝试使用ROLE和USER作为principalTypes。 使用RoleMapping创建用户，角色和主体：

User.create({
    username: 'admin',
    email: '[email protected]',
    password: 'password',
    active: true
}, 
function (err, user) {
    Role.create({
        name: 'Admin'
    }, 
    function (err, role) {
        if (err) throw err;

        console.log('Created role:', role);

        //make user an admin
        role.principals.create({
            principalType: RoleMapping.USER,
            //principalType: RoleMapping.ROLE,
            principalId: user.id,
            active: true
        }, 
        function (err, principal) {
            if (err) throw err;

            console.log('Principal:', principal);
        });
    });
});

客户模型：

"name": "Customer",
"base": "PersistedModel",
"strict": false,
"idInjection": false,
"options": {
    "validateUpsert": true
},

    },

    },
    {
        WORKS AS EXPECTED
        "accessType": "*",

        "principalId": "$authenticated",
        "permission": "ALLOW"
    },
    {
        RETURNS 401 AFTER LOGGING IN AS USER ASSIGNED TO ROLE
        "accessType": "*",
        "principalType": "ROLE",
        "principalId": "Admin",
        "permission": "ALLOW"
    }
],
"methods": []

创建的用户记录：

"_id" : ObjectId("55b7c34d6033a33758038c3b"),
"username" : "admin",
"password" : ....,
"email" : "[email protected]",
"active" : true

角色记录：

"_id" : ObjectId("55b7c34d6033a33758038c3e"),
"name" : "Admin",
"created" : ISODate("2015-07-28T18:00:45.336Z"),
"modified" : ISODate("2015-07-28T18:00:45.336Z")

RoleMapping记录：

"_id" : ObjectId("55b7c34d6033a33758038c41"),
"principalType" : "USER",
"principalId" : "55b7c34d6033a33758038c3b",
"roleId" : ObjectId("55b7c34d6033a33758038c3e"),
"active" : true

在此之前感谢您的帮助！

Answer 1

在principalId中定义用户时，请尝试改为：

principalId: user[0].id,

Answer 2

请注意：

RoleMapping.principalType：USER（表示用户，不是ROLE）

RoleMapping.principalId：USER_ID（因为定义RoleMapping.principalType是USER）

acls：[{“principalType”：“ROLE”，“principalId”：“admin”，}]

我测试过，它正在工作

Role
