ASP.NET 5 RC1：System.IO.InvalidDataException：请求内容意外结束

Question

我正在 Azure Web 应用程序中运行 ASP.NET 5 项目。

在使用大约 1.5mb 或更大的文件（表单数据）调用 API 端点时，会引发以下异常。

Here is where the exception is thrown from.

有谁知道如何解决这个问题？有没有可能的解决方法？

Answer 1

我在aspnet/KestrelHttpServer 上提交了这个。它已被接受为一个错误，最近已包含在 1.0.0-rc2 里程碑中。 See issue here.

Answer 2

好吧，记住 ASP.NEt 5 仍然在 RC 中，所以可能在你的 VS 中当前版本更加不成熟，这个错误看起来有点奇怪，但看起来像是一个 Web 服务器错误。 asp.net 5 的 Web 服务器部分是 kestrell，它与您的堆栈跟踪匹配 Microsoft.AspNet.Server.Kestrel

我会推荐你​​

1. 将您的 Kestrell 服务器程序集更新为 last RC Nov 18 您的 VS 可能正在等待该更新。
2. 如果错误仍然存​​在，请在Kestrell ASP.Net 5 GitHub 中发布问题，这可能是与其他人已经打开谈论内容长度https://github.com/aspnet/KestrelHttpServer/labels/bug 相关的错误
