[英]Sequelize gets stuck connecting to heroku postgres database
SO上有很多這樣的問題,但沒有一個真的有同樣的問題。
我正在嘗試使用 sequelize 連接到 Postgres 數據庫,並在本地與 heroku 上托管的數據庫一起使用。 幾天前它也確實有效,但現在沒有了,並且查看差異在應用程序連接到數據庫的方式上沒有任何變化。
當我部署應用程序時,它在嘗試連接到數據庫時卡住了,直到網絡工作者因為應用程序沒有綁定到端口而引發超時。 這使得調試變得困難,因為我沒有要處理的錯誤。
async connect(): Promise<void> {
const dbUrl = process.env.DATABASE_URL as string
if (!dbUrl) {
throw new Error('Cannot connect to database, url not set!')
}
logger.info(`connecting to database ${dbUrl.replace(/:(\w+)@/, ':***@')}`)
this.sequelize = new Sequelize(dbUrl, {
dialect: 'postgres',
protocol: 'postgres',
logging: (sql, timing) => {
logger.debug(`Executed SQL query '${sql}' in ${timing} ms`)
},
dialectOptions: {
decimalNumbers: true,
ssl: true
}
})
// it gets stuck here
await this.sequelize.authenticate({
logging: (sql, timing) => {
logger.debug(`authentication ${sql}, ${timing}`)
}
})
logger.info('Database connection successful')
logger.info('initializing models...')
await this.initializeModels(this.sequelize)
logger.info('synching database...')
await this.sequelize.sync({
alter: true,
logging: (sql, timing) => {
logger.debug(`Executed SQL query '${sql}' in ${timing} ms`)
}
})
}
這里的日志輸出:

版本
pg
:7.5.0sequelize
:6.3.5這個問題為我指明了正確的方向。 問題是pg
包版本,升級到 8.4.1 后一切正常。
