无法使用 aws-rds url 到达 `postgres`:`5432` 处的数据库服务器

Question

我使用的技术：

• nextJS；
• 棱镜；
• postgresql；
• 码头工人;

我正在尝试通过传递此网址来连接到数据库：

DATABASE_URL="postgresql://USER:PASSWORD@HOST:5432"

它是一个 AWS RDS Postgres 数据库，我确信它工作正常，因为我可以手动连接到它。

schema.prisma：

generator client {
  provider = "prisma-client-js" 
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

我也尝试使用这些网址运行：

DATABASE_URL="postgresql://USER:PASSWORD@HOST:5432/postgres

DATABASE_URL="postgresql://USER:PASSWORD@HOST:5432/postgres?connect_timeout=300"

DATABASE_URL="postgresql://USER:PASSWORD@HOST:5432/postgres?schema=public"

Answer 1

您是否尝试过使用：postgres://USER:PASSWORD@HOST:5432/postgres？
