我是 FeathersJS 的新手并试图将其与 PostgreSQL 连接，但我在使用 SequelizeConnection 时遇到问题，它向我显示了这个错误

信息：Feathers 应用程序在 http://localhost:3030 上启动

错误：未处理拒绝：Promise {"_bitField":18087936,"_fulfillmentHandler0":{"name":"SequelizeConnectionError","parent":{"length":166,"name":"error","severity": "FATAL","code":"28P01","file":"d:\pginstaller_12.auto\postgres.windows-x64\src\backend\libpq\auth.c","line":"333","例程":"auth_failed"},"original":{"length":166,"name":"error","severity":"FATAL","code":"28P01","file":"d: \pginstaller_12.auto\postgres.windows-x64\src\backend\libpq\auth.c","line":"333","routine":"auth_failed"}},"name":"SequelizeConnectionError","parent":{"length":166,"name":"error","severity":"FATAL","code":"28P01","file":"d:\pginstaller_12.auto\ postgres.windows-x64\src\backend\libpq\auth.c","line":"333","routine":"auth_failed"},"original":{"length":166,"name":"错误","严重性":"致命","代码":"28P01","文件":"d:\pginstaller_12.auto\postgres.windows-x64\src\backend\libpq\auth.c","行":"333","例程":"auth_failed"}}文件":"d:\pginstaller_12.auto\postgres.windows-x64\src\backend\libpq\auth.c","line":"333","routine":"auth_failed"},"original":{ “长度”：166，“名称”：“错误”，“严重性”：“致命”，“代码”：“28P01”，“文件”：“d:\pginstaller_12.auto\postgres.windows-x64\src\后端\libpq\auth.c","line":"333","routine":"auth_failed"}}文件":"d:\pginstaller_12.auto\postgres.windows-x64\src\backend\libpq\auth.c","line":"333","routine":"auth_failed"},"original":{ “长度”：166，“名称”：“错误”，“严重性”：“致命”，“代码”：“28P01”，“文件”：“d:\pginstaller_12.auto\postgres.windows-x64\src\后端\libpq\auth.c","line":"333","routine":"auth_failed"}}\pginstaller_12.auto\postgres.windows-x64\src\backend\libpq\auth.c","line":"333","routine":"auth_failed"}}\pginstaller_12.auto\postgres.windows-x64\src\backend\libpq\auth.c","line":"333","routine":"auth_failed"}}

此错误指定您输入无效的连接字符串以将您连接到您的 postgres 数据库。

您需要提供一个有效的连接字符串，如下所示：

postgres://user:password@host:port/db_name

在哪里 ：

  • 用户：它是连接你的 postgres 数据库的用户，
  • 密码：这是用户的密码，
  • 主机：您的数据库可用的主机名（例如，“localhost”，如果 postgres 安装在本地），
  • 端口：默认端口为 5432，
  • db_name：您的数据库的名称。
