在超过一定长度的剃刀页面中使用路由参数导致无效 url 错误

Question

我正在尝试使用名为 {error} 的路由参数将错误消息传递到我在 razor 中的错误页面。但是我一直收到无效的 url 错误。我把它归结为我作为路由参数传递的 url 参数的长度，这导致了这个问题。

但是我不明白这个，因为url的有效长度是2048个字符。而且字符串的长度明显更长。任何见解将不胜感激。

这是一个 returns 无效的 url 错误。总字符数：404，url参数：373

http:///localhost123/Error/An%20error%20occurred%20while%20updating%20the%20entries.%20See%20the%20inner%20exception%20for%20details.The%20INSERT%20statement%20conflicted%20with %20the%20FOREIGN%20KEY%20constraint%20"FK_VthaFormsWorkflow_VthaForms".%20The%20conflict%20occurred%20in%20database%20"MyDWPApps",%20table%20"dbo.VthaForms",%20column%20 %27Id%27.%20The%20statement%20has%20been%20terminated./True

如果我删除最后一句，url 有效。总字符数：359，url参数：328

//Error.cshtml

@page   "{error}/{hidenavbar:bool=false}"
@model ErrorModel

    ViewData["Title"] = "Error";

    if (Model.HideNavbar)
    {
        Layout = "_LayoutHideNavbar";
    }
}

<div class="header-title text-center">
    <h1 class="title">Error</h1>
</div>

<div class="card w-75 text-center mx-auto p-4">
    <div><b>Time of Error:</b> @DateTime.Now.ToShortTimeString()</div>
    <div class="text-danger"><b>Error message:</b> @Model.Error</div>

        [BindProperty(SupportsGet = true)]
        public string Error { get; set; }

        private readonly ILogger<ErrorModel> _logger;

        public ErrorModel(ILogger<ErrorModel> logger)
        {
            _logger = logger;
        }

        public void OnGet()
        {

        }
    }
}

将最终使用 nlog 记录器并将所有内部异常消息传输到 nlog 记录器输出到文件。根据@Steve 的建议，所有用户错误都将显示一条通用错误消息。
