内部服务器错误 - Azure 应用服务自定义控制器 [英] Internal Server Error - Azure App Service Custom Controller

问题描述

我有一个带有多个自定义控制器的 Azure 移动应用服务(不是旧的移动服务)，并且流程运行良好.

I have a Azure Mobile App Service (not old mobileservice), with multiple custom controllers, and the flow works perfectly.

今天发生了一个关于Internal Server Error的错误.

Today an error occurred about Internal Server Error.

我附加了调试器并单步执行了代码，控制器在没有任何错误的情况下到达最后并返回Ok.因此，我一直无法找到根.但是客户端会收到内部服务器错误的错误.

I attached the debugger an stepped through the code, and the controller gets to the end without any errors and hits the return Ok. Therefore I have not been able to find the root. But the client then gets the error that there is an internal server error.

我像这样进行服务器调用:

I make a server call like:

DTO.UserDTO uploadImage = await ((App)Application.Current).MobileService.InvokeApiAsync<DTO.UsernameCheckDto, DTO.UserDTO>("user/blobStorageRetrieval", new DTO.UsernameCheckDto() { Username = ((App)Application.Current).InGameUserName }, System.Net.Http.HttpMethod.Post, null);

自定义控制器以:

return Ok(new UserDTO()
{
    MicrosoftId = stable_sid,
    Username = stable_users.Username,
    playerNames = playerNames,
    playerScores = playerInts,
    isCreated = true,
    bestScore = stable_users.bestRunnerScore,
    statsInformation = _statsInformation,
});

我已验证所有变量都已初始化.类型 UserDTO 是从相同的 Portable Library 引用的.任何人都可以提示我如何找到此错误的原因吗?控制器以前工作过，没有任何变化.

I have verified that all the variables are initialized. The Type UserDTO is referenced from the same Portable Library. Can anybody hint how I can find the cause of this error? The controller has worked before without any changes.

一般错误消息

解决方案建议

搜索 Sid 哦 stackoverflow.发现2年前的一个问题.Web API 转换为 Azure 移动服务未序列化所有属性

我明天试试这个.

推荐答案

解决方案是添加:

httpConfig.Formatters.JsonFormatter.SerializerSettings.DefaultValueHandling = Newtonsoft.Json.DefaultValueHandling.Include;
httpConfig.Formatters.JsonFormatter.SerializerSettings.NullValueHandling = Newtonsoft.Json.NullValueHandling.Include;

到 Startup.MobileApp.cs 方法中的 ConfigureMobileApp.
