错误500 Web API [英] Error 500 Web API
问题描述
我在过去的4个小时内一直在努力解决这个问题。
I've been trying to fix this for the last 4 hours.
我有一个新的Web API项目 - 在开发上100％正常工作，
I have a new Web API Project - which works 100% fine on development,
但是在实时服务器上我收到 500内部服务器错误。
BUT on the live server I get a 500 Internal Server Error.
当我部署新版本并直接向 http：// URL / Action 发送请求时，我得到了错误。 但
如果我先去 http：// URL / 然后将POST请求发送到 http： // URL / Action ，它可以工作。
When I deploy a new version and send a request directly to http://URL/Action I get the error. BUT
If I go to http://URL/ first then send the POST request to http://URL/Action, it works.
对于
因此，首先我需要打开： http：// URL /操作，然后发送 POST 请求。
So for it to work first I have to open: http://URL/Action, then send the POST request.
因此项目使用 Ninject ，这是 Startup.cs
using System.Collections.Generic;
using System.Reflection;
using System.Web.Http;
using API.MyApi;
using Business.Bindings;
using Microsoft.Owin;
using Ninject;
using Ninject.Modules;
using Ninject.Web.Common.OwinHost;
using Ninject.Web.WebApi.OwinHost;
using Owin;
[assembly: OwinStartup(typeof(Startup))]
namespace API.MyApi
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
var config = new HttpConfiguration();
WebApiConfig.Register(config);
app.UseWebApi(config);
app.UseNinjectMiddleware(CreateKernel);
app.UseNinjectWebApi(config);
GlobalConfiguration.Configuration.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
}
private static StandardKernel CreateKernel()
{
var kernel = new StandardKernel();
kernel.Load(Assembly.GetExecutingAssembly());
var modules = new List<INinjectModule>
{
new BusinessBindings(),
new DataBindings()
};
kernel.Load(modules);
return kernel;
}
}
}
WebAPI配置
using System.Web.Http;
namespace API.MyApi
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
config.Formatters.XmlFormatter.UseXmlSerializer = true;
GlobalConfiguration.Configuration.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
}
}
}
我试过添加这一行获取整个错误消息视图的代码：
I have tried adding this line of code to get a view of the entire error message:
GlobalConfiguration.Configuration.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
并将其添加到 web.config file
and also adding this to the web.config file
<customErrors mode="Off"/>
但是我在PostMan中得到的错误是：
But the error I get in PostMan is:
在浏览器中导航到URL.com后：
After I navigate to URL.com in the Browser:
然后如果我发送POST请求：
Then If I send the POST request:
编辑：
这是我的异常处理程序属性：
This is my exception handler attribute:
public class ExceptionHandlerAttribute : ExceptionFilterAttribute
{
public override void OnException(HttpActionExecutedContext actionExecutedContext)
{
var exception = actionExecutedContext.Exception;
using (var exceptionLogger = new CustomLogger("Exceptions"))
{
exceptionLogger.LogExceptionMessage(exception.Message, exception.InnerException, exception.StackTrace);
}
base.OnException(actionExecutedContext);
}
}
并且控制器装饰有属性：
and the Controller is decorated with the attribute:
[ExceptionHandler]
public class SmartOneCController : BaseApiController
{
public SmartOneCController(CustomLogger logger)
{
}
}
那么这个属性应该做的是将异常记录到一个日志文件 - 它正在开发和部署版本上进行测试。
So what this Attribute should do is Log the exception to a log file - Which is working tested on both the Development and the deployed version.
但是没有记录异常从 500内部服务器错误
控制器代码，我看不到控制器代码如何在这里提供帮助，因为在访问API的基本URL之后一切正常： URL.com 之后我可以调用这个POST方法，一切正常。
Controller Code, I don't see how the controller code will help here, as everything works after visiting the Base URL of the API: URL.com after that I can call this POST method and everything works.
[ExceptionHandler]
public class SmartOneCController : BaseApiController
{
public SmartOneCController(CustomLogger logger, IAssetsProvider assetsProvider, ISatelliteTrackerProvider satelliteTrackerProvider) : base(logger, assetsProvider, satelliteTrackerProvider)
{
}
public void Post(HttpRequestMessage request)
{
try
{
// Reading data as XML string to log to files - In case message structure is changed
var xmlDoc = new XmlDocument();
xmlDoc.Load(request.Content.ReadAsStreamAsync().Result);
var str = xmlDoc.InnerXml;
_logger.LogMessage(MessageType.Information, string.Format("RAW XML Message: {0}", str));
// Convert to model
var model = XMLHelper.FromXml<trackermessages>(str);
......
推荐答案
问题在于Startup.cs类，这就是它的工作原理
The Problem was with the Startup.cs class, this is what got it working
[assembly: OwinStartup(typeof(Startup))]
namespace API.MyApi
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
var webApiConfiguration = new HttpConfiguration();
webApiConfiguration.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
app.UseNinjectMiddleware(CreateKernel);
app.UseNinjectWebApi(webApiConfiguration);
}
private static StandardKernel CreateKernel()
{
var kernel = new StandardKernel();
kernel.Load(Assembly.GetExecutingAssembly());
var modules = new List<INinjectModule>
{
new BusinessBindings(),
new DataBindings()
};
kernel.Load(modules);
return kernel;
}
}
}
