将 Sails JS 连接到 SQL 服务器 EXPRESS

Connect Sails JS to SQL Server EXPRESS

我正在学习 Sails JS(和 NodeJS),我正在尝试设置与 SQL Server Express 的连接。我目前拥有的:

一个名为 test-project-db 的数据库,其中包含一个名为 TestTable1 的 table。它有两列:name varchar(20)description varchar(100).

使用 sails new 生成的帆项目,以及使用 sails generate api TestTable1 制作的 model/component。

我的文件: - api/models/TestTable1.js

module.exports = {

  attributes: {

    name: {
      type: 'string',
    },

    description: {
      type: 'string',
    },

  }
};

- config/connections.js:

sqlserver: {
    adapter : 'sails-sqlserver',
    user    : 'sa',
    password: 'passw',
    host    : 'localhost\SQLEXPRESS',
    database: 'test-project-db'
  }

- config/models.js:

module.exports.models = {

  connection: 'sqlserver',

  migrate: 'safe',

};

但是当我 运行 使用 sails lift 的服务器并转到 localhost:1337/testtable1 时,我得到错误:

(node:15756) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): ConnectionError: Failed to connect to localhost:undefined in 60000ms
(node:15756) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

而且,如果我使用 sails-mssqlserver 而不是 sails-sqlserver,我会得到(在控制台中):

在浏览器中:

[Error (E_UNKNOWN) Encountered an unexpected error] Details:  ConnectionError: Failed to connect to localhost:undefined in 60000ms

沿着 500 错误页面。

知道我做错了什么吗?

localhost:undefined --> 端口未定义,因为您没有在配置中提供它。将 port 属性添加到 config/connections.js 内的 sqlserver 连接中,并为其分配数据库服务器的端口。

旁注:在学习 Node 的同时学习 Sails 的情况很少见,尤其是因为 Sails 起初看起来很吓人。一点一点地看,你一定会掌握它的窍门的。如果您熟悉 MVC 框架,例如 Rails,那么 Sails 会非常适合。
