我正在学习 Sails JS(和 NodeJS),并且正在尝试设置与 SQL Server Express 的连接。到目前为止我所拥有的:

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

使用 sails new 生成的 sails 项目,以及使用 sailsgenerate api TestTable1 生成的模型/组件。

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',

};

但是当我使用 sails lift 运行服务器并转到 localhost:1337/testtable1 时,我收到错误:

(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):

{"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 500 错误页面。

知道我做错了什么吗?

最佳答案

localhost:undefined --> 该端口未定义,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 是相当困难的,特别是因为 Sails 乍一看可能看起来很吓人。只要一点一点地看,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 会让您感到宾至如归。
