将自定义回送用户模型与回送组件密码一起使用 [英] Using custom Loopback user model with loopback-component-passport

问题描述

我正在尝试将扩展的回送用户模型与loopback-component-passport一起用于Facebook登录.登录本身正在运行，但我无法使用其自定义用户模型而不是内置的用户".

我采取的步骤:

-使用slc环回创建自定义用户模型:扩展用户"的模型

{
  "name": "myuser",
  "plural": "myusers",
  "base": "User",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "mytestproperty": {
      "type": "string",
      "default": "myteststring"
    }
  },
  "validations": [],
  "relations": {},
  "acls": [],
  "methods": {}
}

-使用新的用户模型设置护照组件:

module.exports = function (app) {
  var passportConfigurator = new PassportConfigurator(app);

  passportConfigurator.init();
  passportConfigurator.setupModels({
    userModel: app.models.myuser,
    userIdentityModel: app.models.UserIdentity,
    userCredentialModel: app.models.UserCredential
  });
  passportConfigurator.configureProvider('facebook-login',
    require('../../providers.json')['facebook-login']);
};

问题: 当我通过Facebook登录时，护照组件仍使用db.json存储中所示的用户"模型:

{
  "ids": {
    "User": 2,
    "UserCredential": 1,
    "UserIdentity": 2,
    "AccessToken": 2,
    "ACL": 1,
    "RoleMapping": 1,
    "Role": 1,
    "myuser": 1
  },
  "models": {
    "User": {
      "1": "{\"username\":\"facebook.13371337\",\"password\":\"blablabla\",\"email\":\"blablabla\",\"id\":1}"
    },
    "UserCredential": {},
    "UserIdentity": {
      "1": "{\"provider\":\"ALL MY IDENTITY INFO BLABLABLA}"
    },
    "AccessToken": {
      "1337": "{\"id\":\"1337\",\"ttl\":1209600,\"created\":\"2017-03-01T09:34:51.965Z\",\"userId\":1}"
    },
    "ACL": {},
    "RoleMapping": {},
    "Role": {},
    "myuser": {}
  }
}

如您所见，用户"中填充了我新创建的用户，我的用户"为空.

我误会什么，还是将回传用户与护照一起扩展的正确方法是什么? 任何提示或对示例的引用都将不胜感激！

解决方案

您将必须扩展所有与护照相关的模型，以便可以将它们链接到自定义用户模型.

user.json

{
  "name": "user",
  "plural": "users",
  "base": "User",
  "relations": {
    "accessTokens": {
      "type": "hasMany",
      "model": "accessToken",
      "foreignKey": "userId"
    },
    "identities": {
      "type": "hasMany",
      "model": "userIdentity",
      "foreignKey": "userId"
    },
    "credentials": {
      "type": "hasMany",
      "model": "userCredential",
      "foreignKey": "userId"
    }
  },
  "validations": [],
  "acls": [],
  "methods": []
}

user-identity.json

{
  "name": "userIdentity",
  "plural": "userIdentities",
  "base": "UserIdentity",
  "properties": {},
  "validations": [],
  "relations": {
    "user": {
      "type": "belongsTo",
      "model": "user",
      "foreignKey": "userId"
    }
  },
  "acls": [],
  "methods": []
}

user-credential.json

{
  "name": "userCredential",
  "plural": "userCredentials",
  "base": "UserCredential",
  "properties": {},
  "validations": [],
  "relations": {
    "user": {
      "type": "belongsTo",
      "model": "user",
      "foreignKey": "userId"
    }
  },
  "acls": [],
  "methods": []
}

access-token.json

{
  "name": "accessToken",
  "plural": "accessTokens",
  "base": "AccessToken",
  "properties": {},
  "validations": [],
  "relations": {
    "user": {
      "type": "belongsTo",
      "model": "user",
      "foreignKey": "userId"
    }
  },
  "acls": [],
  "methods": {}
}

server.js(相关部分)

const PassportConfigurator = require('loopback-component-passport').PassportConfigurator
const passportConfigurator = new PassportConfigurator(app)

let providersConfig = require('./providers.json')

passportConfigurator.init()

passportConfigurator.setupModels({
  userModel: app.models.user,
  userIdentityModel: app.models.userIdentity,
  userCredentialModel: app.models.userCredential
})

for (let s in providersConfig) { // Configure providers based on providers.json config
  let c = providersConfig[s]
  c.session = c.session !== false
  passportConfigurator.configureProvider(s, c)
}

还有示例存储库，这可能对您有用. /p>

I'm trying to use a extended loopback user model together with the loopback-component-passport for facebook login. The login itself is working but i can't get it to use my custom user model instead of the builtin "Users".

steps i took:

- create custom user model with slc loopback:model extending "User"

{
  "name": "myuser",
  "plural": "myusers",
  "base": "User",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "mytestproperty": {
      "type": "string",
      "default": "myteststring"
    }
  },
  "validations": [],
  "relations": {},
  "acls": [],
  "methods": {}
}

- Setup passport component with the new user model:

module.exports = function (app) {
  var passportConfigurator = new PassportConfigurator(app);

  passportConfigurator.init();
  passportConfigurator.setupModels({
    userModel: app.models.myuser,
    userIdentityModel: app.models.UserIdentity,
    userCredentialModel: app.models.UserCredential
  });
  passportConfigurator.configureProvider('facebook-login',
    require('../../providers.json')['facebook-login']);
};

Problem: When i log in with via facebook the passport component still uses the "Users" model as seen in my db.json storage:

{
  "ids": {
    "User": 2,
    "UserCredential": 1,
    "UserIdentity": 2,
    "AccessToken": 2,
    "ACL": 1,
    "RoleMapping": 1,
    "Role": 1,
    "myuser": 1
  },
  "models": {
    "User": {
      "1": "{\"username\":\"facebook.13371337\",\"password\":\"blablabla\",\"email\":\"blablabla\",\"id\":1}"
    },
    "UserCredential": {},
    "UserIdentity": {
      "1": "{\"provider\":\"ALL MY IDENTITY INFO BLABLABLA}"
    },
    "AccessToken": {
      "1337": "{\"id\":\"1337\",\"ttl\":1209600,\"created\":\"2017-03-01T09:34:51.965Z\",\"userId\":1}"
    },
    "ACL": {},
    "RoleMapping": {},
    "Role": {},
    "myuser": {}
  }
}

As you can see "Users" is populated with my newly created user and "myuser" is empty.

Am i mistaking something or what is the correct way to extend the loopback user together with passport? Any tips or references to a example are greatly appreciated!

解决方案

You will have to extend all passport related models, so you can have them linked to your custom user model.

user.json

{
  "name": "user",
  "plural": "users",
  "base": "User",
  "relations": {
    "accessTokens": {
      "type": "hasMany",
      "model": "accessToken",
      "foreignKey": "userId"
    },
    "identities": {
      "type": "hasMany",
      "model": "userIdentity",
      "foreignKey": "userId"
    },
    "credentials": {
      "type": "hasMany",
      "model": "userCredential",
      "foreignKey": "userId"
    }
  },
  "validations": [],
  "acls": [],
  "methods": []
}

user-identity.json

{
  "name": "userIdentity",
  "plural": "userIdentities",
  "base": "UserIdentity",
  "properties": {},
  "validations": [],
  "relations": {
    "user": {
      "type": "belongsTo",
      "model": "user",
      "foreignKey": "userId"
    }
  },
  "acls": [],
  "methods": []
}

user-credential.json

{
  "name": "userCredential",
  "plural": "userCredentials",
  "base": "UserCredential",
  "properties": {},
  "validations": [],
  "relations": {
    "user": {
      "type": "belongsTo",
      "model": "user",
      "foreignKey": "userId"
    }
  },
  "acls": [],
  "methods": []
}

access-token.json

{
  "name": "accessToken",
  "plural": "accessTokens",
  "base": "AccessToken",
  "properties": {},
  "validations": [],
  "relations": {
    "user": {
      "type": "belongsTo",
      "model": "user",
      "foreignKey": "userId"
    }
  },
  "acls": [],
  "methods": {}
}

server.js (relevant part)

const PassportConfigurator = require('loopback-component-passport').PassportConfigurator
const passportConfigurator = new PassportConfigurator(app)

let providersConfig = require('./providers.json')

passportConfigurator.init()

passportConfigurator.setupModels({
  userModel: app.models.user,
  userIdentityModel: app.models.userIdentity,
  userCredentialModel: app.models.userCredential
})

for (let s in providersConfig) { // Configure providers based on providers.json config
  let c = providersConfig[s]
  c.session = c.session !== false
  passportConfigurator.configureProvider(s, c)
}

There is also an example repository, which might be useful for you.
