RequestError：连接丢失 - 读取 ECONNRESET

Question

我是 mssql 的新手，在我将它部署到我的开发环境中时出现错误，但在本地它只适用于特定查询它不起作用

这是我的代码

 return Order.query()
.joinEager('[shipments.shipmentQuantities.lineItem, lineItems.shipmentQuantities]')
.findById(id);

使用版本 10 和反对 1.4.0 的 nodejs

这是我的连接文件

database: {
  client: 'mssql',
  connection: {
    host: process.env.DB_HOST,
    user: process.env.DB_USER,
    password: process.env.DB_PASSWORD,
    database: process.env.DB_NAME,
    charset: 'utf8',
    stream: true,
       options: process.env.ENABLE_DB_SSL ? {
       port: 1433,
       database: process.env.DB_NAME,
       encrypt: true,
    } : undefined,
   },
    debug: false,
  },

错误详情

RequestError: Connection lost - read ECONNRESET

对于初始数据库设置，我使用的是 knex，这里是初始代码

import body = require('koa-body');
import compress = require('koa-compress');
import Objection = require('objection');
import errorHandler = require('koa-json-logger-next');
import responseTime from 'koa-response-time-next/lib';
import config from './configuration';
import * as Koa from 'koa';
const Model = Objection.Model;

export default class Config {

   constructor(private app: Koa) {
   this.app = app;
 }

 public build() {
   // db setup
  const knex = require('knex')(config.database);
  Model.knex(knex);
  this.app.use((ctx: Koa.Context, next: () => Promise<any>) => {
  ctx.knex = knex;
  return next();
  });
  // return response time in X-Response-Time header
  this.app.use(responseTime());

  // HTTP compression
   this.app.use(compress({}));

  // parse request body into ctx.request.body
  this.app.use(body());

  // Global Error handling
  this.app.use(errorHandler({
  // As this is behind the api gateway, surface errors
  surfaceErrors: true,
  }));

  return config;
}

}

如果数据库实例也在 azure 上，您能否尝试以下配置：

knex({
  client : 'mssql',
  connection: {
    database: 'mydatabase',
    server: 'myserver.database.windows.net',
    user: 'myuser',
    password: 'mypass',
    port: 1433,
    connectionTimeout: 30000,
    options: {
      encrypt: true
    }
  }
});

如果数据库实例位于 azure 上，则 encrpt 属性必须设置为 true。
