ASP.NET Core 应用日志中出现很多 "Unexpected end of request content" 错误

悬赏园豆：30 [待解决问题]

用的是 ASP.NET Core 9.0，出现这个错误的是下面这个 Controller Action

public class EventController : ApiControllerBase
{
    [HttpPost]
    public async Task<IActionResult> ReportEventAsync([FromBody] EventDto reportedEvent)
    {
        // ...
    }
}

详细的异常信息如下

请问如何消除或者忽略这个异常？

是不是请求体被提前使用了没有复位导致框架[Frombody]为空了啊

前面没有我们自己实现的处理代码

先临时通过设置更高的日志级别忽略了

{ 
  "Serilog": {
      "MinimumLevel": {
        "Default": "Warning",
        "Override": {
          "Microsoft.AspNetCore.Server.Kestrel": "Fatal"
        }
      }
    }
}

在 appsettings.Development.json 或 appsettings.Production.json 中：

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning",
      "Microsoft.AspNetCore.Server.Kestrel": "Information" // 将 Kestrel 的默认错误级别降低
    },
    "Console": {
      "LogLevel": {
        "Default": "Information",
        "Microsoft.AspNetCore.Server.Kestrel": "Information" 
      },
      "FilterOptions": {
        "Filters": [
          {
            "CategoryName": "Microsoft.AspNetCore.Server.Kestrel",
            "LogLevel": "Information",
            "ProviderName": "Console",
            "Filter": (logEntry) => {
              // 注意：这个 lambda 语法在 appsettings.json 中无法直接使用。
              // 实际配置需要通过代码或第三方库实现这种复杂过滤。
              // 这表明了其复杂性。
              return !logEntry.Exception?.Message.Contains("Unexpected end of request content") ?? true;
            }
          }
        ]
      }
    }
  }
}
