无法使用mysql创建数据源 [英] Can not created the Datasource with mysql

问题描述

我正在使用mysql创建回送应用程序.我确定数据源将是mysql，但是当我运行应用程序时，在控制台窗口中出现了以下错误.

I am creating loopback applications with mysql . I set out the datasource will be mysql but when i run the applications i got following error in console windows .

参考错误:无法创建数据源商店":无法初始化连接器"mysql":时间未定义

这是我的datasource.json代码.

Here is my datasource.json code .

{
  "db": {
    "name": "db",
    "connector": "memory"
  },
  "shop": {
    "host": "localhost",
    "port": 8081,
    "url": "",
    "database": "shoppingdatabase",
    "password": "",
    "name": "shop",
    "user": "root",
    "connector": "mysql",
    "connectTimeout":9000000
  }
}

这是model.json的代码

Here is the code for model.json

{
  "_meta": {
    "sources": [
      "loopback/common/models",
      "loopback/server/models",
      "../common/models",
      "./models"
    ],
    "mixins": [
      "loopback/common/mixins",
      "loopback/server/mixins",
      "../common/mixins",
      "./mixins"
    ]
  },
  "User": {
    "dataSource": "db"
  },
  "AccessToken": {
    "dataSource": "db",
    "public": false
  },
  "ACL": {
    "dataSource": "db",
    "public": false
  },
  "RoleMapping": {
    "dataSource": "db",
    "public": false,
    "options": {
      "strictObjectIDCoercion": true
    }
  },
  "Role": {
    "dataSource": "db",
    "public": false
  },
  "carts": {
    "dataSource": "shop",
    "public": true
  },
  "products": {
    "dataSource": "shop",
    "public": true
  },
  "users": {
    "dataSource": "shop",
    "public": true
  },
  "vendors": {
    "dataSource": "shop",
    "public": true
  }
}

这是我运行服务器时的屏幕截图.

推荐答案

将datasource.json更改为:

Change your datasource.json as :

    {
      "db": {
      "host": "localhost",
      "port": 3306,
      "url": "",
      "database": "shoppingdatabase",
      "password": "",
      "name": "db",
      "user": "root",
      "connector": "mysql",
      "connectTimeout":9000000
     }
   }

和model.json为

and model.json as

    {
     "_meta": {
     "sources": [
       "loopback/common/models",
       "loopback/server/models",
       "../common/models",
       "./models"
      ],
     "mixins": [
       "loopback/common/mixins",
       "loopback/server/mixins",
       "../common/mixins",
       "./mixins"
      ]
    },
    "User": {
     "dataSource": "db"
    },
    "AccessToken": {
     "dataSource": "db",
     "public": false
    },
    "ACL": {
     "dataSource": "db",
     "public": false
    },
    "RoleMapping": {
     "dataSource": "db",
     "public": false,
     "options": {
       "strictObjectIDCoercion": true
      }
    },
    "Role": {
     "dataSource": "db",
     "public": false
    },
    "carts": {
     "dataSource": "db",
     "public": true
    },
    "products": {
     "dataSource": "db",
     "public": true
    },
    "users": {
     "dataSource": "db",
     "public": true
    },
    "vendors": {
     "dataSource": "db",
     "public": true
    }
  }

，然后在MySQL中手动创建名称为"shoppingdatabase"的数据库，因为回送将需要预先创建数据库. 并保持密码保护.

and before that create a database in MySQL manually with the name "shoppingdatabase" as loopback will need the database pre-created. And keep it password protected too.
