将Sails连接到

Question

我正在学习Sails (和NodeJS)，并试图设置到的连接。到目前为止我所拥有的是：

一个名为test-project-db的数据库，里面有一个名为TestTable1的表。它有两列：name varchar(20)和description varchar(100)。

一个用sails new生成的sails项目，以及一个用sails generate api TestTable1生成的模型/组件。

我的文件：-api/model/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 s.js：

module.exports.models = {

  connection: 'sqlserver',

  migrate: 'safe',

};

但是，当我使用sails lift运行服务器并转到localhost:1337/testtable1时，我得到了错误：

(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，如果我不使用sails-sqlserver，而是使用sails-mssqlserver，那么(在控制台中)：

{"name":"Sails-MSSqlserver","hostname":"DESKTOP-PMN0K03","pid":15928,"level":30,"msg":"Error in __FIND__: { ConnectionError: Failed to connect to localhost:undefined in 60000ms\n    at Connection.<anonymous> (D:\\Práctica 2\\test-project\\node_modules\\sails-mssqlserver\\node_modules\\mssql\\lib\\tedious.js:378:25)\n    at Object.onceWrapper (events.js:315:30)\n    at emitOne (events.js:116:13)\n    at Connection.emit (events.js:211:7)\n    at Connection.connectTimeout

在浏览器中：

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

沿着一个500错误页。

知道我做错什么了吗？

Answer 1

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中的sqlserver连接中，并将其分配给数据库服务器的端口。

边注:边学边学Node是很难的，特别是因为Sails一开始看起来很吓人。把它一片一片地拿着，你一定会明白的。如果您熟悉MVC框架(如Rails )，那么Sails就会有宾至如归的感觉。
