原本是好的,后边被其他人好像改了数据库端口,后面改回来后就报这个错了。希望有大佬能看看 数据库配置 ` let app = { user: ‘xx’, password: ‘xx’, server: ‘127.0.0.1’, database: ‘xxxx’, port: 2223, options: { encrypt: true, trustServerCertificate: true, }, pool: { min: 0, max: 100, idleTimeoutMillis: 3000, },

}; 数据库连接代码 const mssql = require(‘mssql’); const config = require("./config.js");

const pool1 = new mssql.ConnectionPool(config); const pool1Connect = pool1.connect();

pool1.on(‘error’, err => { // … error handler })

async function query(sql,callback ) { await pool1Connect; // ensures that the pool has been created try { const request = pool1.request(); // or: new sql.Request(pool1) const result = await request.query(sql) callback(null, result); } catch (err) { callback(err, null); console.error(‘SQL error’, err); } } ` (node:11964) UnhandledPromiseRejectionWarning: ConnectionError: Failed to connect to 127.0.0.1:2223 - Cannot call write after a stream was destroyed at Connection.<anonymous> (D:\WX\wechatService - 副本\node_modules\mssql\lib\tedious.js:244:17) at Object.onceWrapper (events.js:422:26) at Connection.emit (events.js:315:20) at Connection.socketError (D:\WX\wechatService - 副本\node_modules\tedious\lib\connection.js:1095:12) at Socket.<anonymous> (D:\WX\wechatService - 副本\node_modules\tedious\lib\connection.js:971:14) at Socket.emit (events.js:327:22) at errorOrDestroy (internal/streams/destroy.js:108:12) at onwriteError (_stream_writable.js:418:5) at onwrite (_stream_writable.js:445:5) at doWrite (_stream_writable.js:399:11)
