Postgresql .NET Core 3.1 Postgres连接字符串Docker

我正试图用postgres docker映像在docker上运行我的asp net核心web api。 它在-IIS上工作：

“连接字符串”：“服务器=127.0.0.1；端口=5400；数据库=test；用户名=postgres；密码=test；”

它在IIS上工作正常（端口5400-docker正在映射到5432）

它不适用于Docker：

当我将连接字符串更改为：

“ConnectionString”：“主机=posgres；端口=5400；数据库=test；用户名=postgres；密码=test；”

我在docker上也有同样的错误，但它在IIS上不起作用

当我将连接字符串更改为：

“ConnectionString”：“@Host=postgres；Port=5400；Database=test；Username=postgres；Password=test；”

我有一个例外：

不支持关键字：@host'
