我有一个调用我的ApiController这是返回一个504,我只是不能解决我在做什么错...ApiController返回504 - 服务器未返回此请求的完整响应。服务器返回0字节
任何人都可以看到我的问题?
这是控制器:
public class SA_GetAllLocationsController : ApiController
{
[Route("SA_GetAllLocations")]
[HttpGet]
public List<SA_Locations> Get()
{
List<SA_Locations> result = SADatastore.Functions.Location.GetAllLocations(Settings.Default.ConnectionString);
return result;
}
}
这是由实体框架数据库首先生成的类SA_Locations ...
public partial class SA_Locations
{
public SA_Locations()
{
this.SA_Items = new HashSet<SA_Items>();
}
public string LocationID { get; set; }
public string BuildingID { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public string MISID { get; set; }
public string GPSCoords { get; set; }
public string QRCode { get; set; }
public Nullable<bool> Signable { get; set; }
public Nullable<bool> Auditable { get; set; }
public Nullable<bool> Bookable { get; set; }
public Nullable<bool> Entrance { get; set; }
public Nullable<bool> Exit { get; set; }
public Nullable<bool> Active { get; set; }
public System.DateTime LastUpdated { get; set; }
public virtual SA_Buildings SA_Buildings { get; set; }
public virtual ICollection<SA_Items> SA_Items { get; set; }
}
我写了一个小的“状态”功能,工作原理完美,看起来像这样:
public HttpResponseMessage Get()
{
return new HttpResponseMessage()
{
Content = new StringContent(
"SA service is running and ready to accept connections!",
Encoding.UTF8,
"text/html"
)
};
}
我只是不能解决为什么SA_Loc当我调试时,似乎没有错误返回ation,但是我在Fiddler中看到的响应是:
504 - 服务器没有为此请求返回完整的响应。服务器返回0字节
对象是否太复杂而无法返回?
任何帮助将非常感谢!

UPDATE
我决定试试,看看我刚刚从控制器返回纯JSON,所以我重新写控制器如下会发生什么:
public class SA_GetAllLocationsController : ApiController
{
[Route("SA_GetAllLocations")]
[HttpGet]
public HttpResponseMessage Get()
{
List<SA_Locations> result = SADatastore.Functions.Location.GetAllLocations(Settings.Default.ConnectionString);
string output = JsonConvert.SerializeObject(result);
return new HttpResponseMessage()
{
Content = new StringContent(
output,
Encoding.UTF8,
"application/json"
)
};
}
}
现在实际上抛出一个错误序列化SA_Locations对象到一个字符串!
的错误信息是:
类型的异常“Newtonsoft.Json.JsonSerializationException”发生Newtonsoft.Json.dll但在用户代码
附加信息没有被处理的:错误获取值从'System.Data.Entity.DynamicProxies.SA_Locations_720FF8784B152496318F87BCB674E344B97C0446B16D4DC2BDDC381D88C048B9'上的'SA_Buildings'。
所以,它指向的东西走向与SA_Locations,这是我说的做,是
越来越近的实体框架数据库第一生成的类....但不知道为什么这已赢得” t序列化?
