使用用户模型时，不断在回送中出现401错误 [英] Constantly getting 401 errors in loopback while using User Model

问题描述

我是回传的新手，我无法正确扩展User Base模型.虽然在资源管理器中它显示它已扩展，但是所有API都给出401错误.前任.在正常情况下，我会得到/users的电话.

I am new to loopback and I am not able to extend User Base model properly. Though in explorer it shows that it is extended but all API's give a 401 error. ex. In normal get call for /users I get..

{
  "error": {
    "name": "Error",
    "status": 401,
    "message": "Authorization Required",
    "statusCode": 401,
    "code": "AUTHORIZATION_REQUIRED",
    "stack": "Error: Authorization Required"
  }
}

我浏览了所有链接和问题，但没有一个对我有用.我已经在用户配置扩展模型的Model-config中正确地设置了public:true并编写了ACL等，但是它们都不起作用.我也对git提出了关于Strongloop的问题: https://github.com/strongloop/loopback/Issues 1809 .任何线索都将很棒.谢谢.

I went thru all the links and questions but none of they are working for me. I have properly put public:true in model-config for User Model extended model and written acls etc. but none of them works. I have also raised an issue on git for strongloop: https://github.com/strongloop/loopback/issues/1809 . Any leads would be awesome. Thanks.

User.json如下:

User.json is as below:

{
  "name": "user",
  "plural": "users",
  "base": "User",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "mongodb": {
    "collection": "User"
  },
  "properties": {
    "name": {
      "type": "string",
      "required": true
    },
    "email": {
      "type": "string",
      "required": true
    },
    "password": {
      "type": "string",
      "required": true
    },
    "phone": {
      "type": "string"
    }
  },
  "validations": [],
  "relations": {
    "question": {
      "type": "hasMany",
      "model": "question",
      "foreignKey": ""
    }
  },
  "acls": [
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "$everyone",
      "permission": "DENY"
    },
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "admin",
      "permission": "ALLOW"
    },
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "$owner",
      "permission": "ALLOW"
    },
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "$everyone",
      "permission": "ALLOW"
    }
  ],
  "methods": {}
}

推荐答案

一些注意事项值得考虑:

Some notes meriting consideration though:

1)您正在定义电子邮件，密码，..属性，尽管在父用户模型中已经完全以相同的方式定义了它们；请参阅: https://github.com/strongloop/loopback/blob/master/common/models/user.json ;

1)You are defining email, password,.. properties, although they are already defined exactly the same way in the parent User model; please see: https://github.com/strongloop/loopback/blob/master/common/models/user.json;

2)对于ACL，您缺少访问类型，它们不正确，但是它们不会破坏任何内容...有关ACL的更多信息，请参见:

2)For ACLs you are missing accesstypes, they are not right, but they do not break anything...For more info about ACL please see: https://docs.strongloop.com/display/public/LB/Define+access+controls

3)另外，在登录时，请确保使用已创建的用户(一个POST请求)，并且该用户已经在数据库中.

3)Also when you login please make sure to use user that you have created(a POST request) and it is in database already.

谢谢！
