Question

所以我正在从SQL Server迁移到PostgreSQL，我正在为迁移期构建一个临时解决方案，以允许我的ASP.NET应用程序连接到我的Heroku Postgres数据库并使用Entity Framework等。

到目前为止，我已经设法从pgAdmin III连接到数据库的Windows没有问题，但是当从ASP.NET应用程序连接时，我收到此错误：

CertificateUnknown：不接受服务器证书。链状态：已处理证书链，但终止于信任提供程序不信任的根证书。。证书中不存在指定的主机名。

我仍然是heroku的新手，但是为什么我可以使用与我的ASP.NET应用程序相同的设置连接pgAdmin，但它在应用程序本身中无效。

Answer 1

使用Npgsql 3.1.5尝试在连接字符串中使用“Trust Server Certificate = true”。连接字符串示例：

Server=[servername];Port=[port];User Id=[username];Password=[password];Database=[databasename];sslmode=Require;Trust Server Certificate=true

连接到Heroku Postgres数据库
