HTTP/2 连接错误 (PROTOCOL_ERROR): 请求 headers 太长

HTTP/2 connection error (PROTOCOL_ERROR): Request headers too long

我有一个视图应该能够显示大字符串值(~20k 个字符)。

过去,此值在 razor *.cshtml 页面中呈现为文本区域值。但是当我在 firefox 中显示网页时,浏览器没有加载页面。 (这里没有进一步的错误描述)

我决定不再在 *.cshtml 页面中呈现 textarea 值。因此,我添加了一个脚本,当用户单击按钮时,该脚本通过 $.get() 加载数据。

但我仍然无法处理大值..!?为什么是这样?大值仅在服务器端处理 - 不传输到客户端!还是我错了?

我现在已经将日志级别(在appsettings.Development.json)改为debug

现在我得到以下错误:

Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http2.Http2ConnectionErrorException: HTTP/2 connection error (PROTOCOL_ERROR): Request headers too long.

我现在在我的控制器中使用 HttpContext.Session 而不是 TempData。就是这样..
