Blazor WASM 异常导致数百个额外的套接字和连接异常

Question

我刚开始学习 Blazor WASM（通常我是后端开发人员），我对经常看到的事情感到困惑。

这可能是一个非常菜鸟的问题，但请耐心等待。

为什么 Blazor 经常不停地抛出异常？

它从一个像这样的具体异常开始，我仍然理解这一点（显然作为一个完整的 Blazor 菜鸟，我不知道我在做什么；但唯一相关的部分是抛出一个异常） :

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Microsoft.AspNetCore.Components.Forms.InputNumber`1[System.Int32] requires a cascading parameter of type EditContext. For example, you can use Microsoft.AspNetCore.Components.Forms.InputNumber`1[[System.Int32, System.Private.CoreLib, Version=5.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]] inside an EditForm.

但后来发生了这种情况，并且一直持续下去：

发生异常的组件非常简单。基本上我只是开始尝试一些领域（正如我所指出的，我显然不知道我在做什么，但这无关紧要，除非它直接导致上述异常的洪流）：

@page "/test"

<InputNumber TValue="int" ValueChanged="numberEntered"></InputNumber>

<p>The number you entered is: </p>

<InputText @ref="inputText"></InputText>

@code {
    InputText inputText;

    void numberEntered(int number)
    {
        inputText.Value = number.ToString();
    }
}

Answer 1

您“简单”的一段代码违反了一些规则。

我赞同@MisterMagoo 所说的。从服务器开始，让调试变得容易。

输入控件需要在具有有效 EditContext 或 Model

EditForm

您通常应该使用 @bind-Value 将字段或属性绑定到控件，如下所示。阅读有关绑定的信息。
InputText.Value 在组件上设置参数 - nono。

这是您的代码版本：

<EditForm Model="model">
    <InputNumber TValue="int" @bind-Value="model.Value"></InputNumber>
</EditForm>

<div>@model.Value</div>
@code {

    Model model = new Model() { Value = 4 };

    class Model
    {
        public int Value { get; set; } = 0;
    }
}

开始使用 MSDocs - Blazor 或其他 Blazor 参考。在我早期，它是我的圣经。

Answer 2

您最初的错误很好地说明了问题所在：

Unhandled exception rendering component: Microsoft.AspNetCore.Components.Forms.InputNumber`1[System.Int32] requires a cascading parameter of type EditContext. For example, you can use Microsoft.AspNetCore.Components.Forms.InputNumber`1[[System.Int32, System.Private.CoreLib, Version=5.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]] inside an EditForm.

InputNumber 是一个内置的 number 类型输入，需要 CascadingValue 类型的 EditContext。 Read Cascading Parameters and Values here.

如果您不关心验证，请改用简单的 <input>。否则，你需要一个父组件来提供一个EditContext：EditForm是一个内置的解决方案；从这里开始。

您的后续错误 (Exception thrown: 'System.Net.Sockets.SocketException') 可能是调试器尝试重新连接到您的应用程序但由于您的应用程序运行进入未处理的异常（上图）并停止执行而失败。您的调试器不知道连接关闭的原因并将继续重试连接。
