响应正文中的无效字符

Question

我正在将现有的 MVC5 json 网络服务迁移到完整框架 (NET 4.6.1) 上的 AspNet Core RC2 运行。

每个控制器都继承自 _BaseController：

public class _BaseController : Controller
{
   public IActionResult Success(object data) { return Json({ IsSuccess = true, Data = data }); }
   public IActionResult Error(string message) { return Json({ IsSuccess = false, Message = message }); }
}

这是一个示例控制器：

public class SampleController : _BaseController
{
   public IActionResult Something() { return Success(new { FirstItem = "First", SecondItem = "Second", ThirdItem = 1 }); }
}

在 RC1 上这工作正常。反应很好。

更新到 RC2 后，JSON 响应现在包含一些 strange/invalid 个字符。

来自 Fiddler，这是原始（有效）响应：

{"isSuccess":true,"data":{"firstItem":"first","secondItem":"second","thirdItem":1}}

但是 RC2 提供了这样的无效响应（来自 Fiddler 的完整原始响应，与 .NET winforms 客户端收到的响应相同）：

HTTP/1.1 200 OK
Transfer-Encoding: chunked
Content-Type: application/json; charset=utf-8
Server: Kestrel
X-Powered-By: ASP.NET

这让我发疯。有谁知道它是否与 Kestrel 和 IIS 之间的集成有关？有什么线索吗？

是的，正如 CodeCaster 评论的那样，这完全是关于响应的问题。

我也会尝试修复客户端，但对此有修复。

因此，如果有人再次遇到此问题，只需在 package.json 上添加对 Microsoft.AspNetCore.Buffering 的引用，并在 Startup.cs 上添加此行：

app.UseResponseBuffering();
