Question

我已经在IIS中托管了一个asp.net webapi项目。对该项目的api调用会引发错误，如下所述。将项目托管到另一个Web服务器的IIS中时，相同的webapi调用可以正常工作。

 [RoutePrefix("api/datacc")]
    public class DataAccessController : ApiController
    {
        [HttpGet]
        [Route("")]
        public int HeartBeat()
        {
            return 1;
        }               
}

错误

我敢打赌，从您遇到问题的新IIS服务器连接到数据库时会出现问题。这来自NHibernate，所以这是数据库的问题。但是，如果它在一台服务器上工作，则可能配置正确。确认您可以直接从新的IIS服务器访问数据库。
