网址验证属性将“ localhost”标记为无效网址 [英] Url validation attribute marks `localhost` as invalid Url

问题描述

在我们的ASP.MVC项目中，我们使用DataAnnotations属性进行验证。字段之一应包含Url，并用 [Url] 属性标记。但是，如果我将 http：// localhost：13030 放入字段值，则不会通过验证。

In our ASP.MVC project we are using DataAnnotations attributes for validation. One of the fields should contains Url and it is marked with [Url] attribute. But if I put http://localhost:13030 into the field value it isn't passing the validation.

是否可以使用该属性将 localhost 定义为有效目标？

Is there any way to use the attribute to define localhost as a valid target?

推荐答案

UrlAttribute 针对此处源代码中显示的RegEx进行验证： https://github.com/Microsoft/referencesource/blob/master/System.ComponentModel.DataAnnotations/DataAnnotations/UrlAttribute.cs# L46 。

UrlAttribute validates against the RegEx shown in the source code here: https://github.com/Microsoft/referencesource/blob/master/System.ComponentModel.DataAnnotations/DataAnnotations/UrlAttribute.cs#L46.

http：// localhost 由于缺少。。

其他选项请参见以下答案：如何在C＃中验证localhost的网址。

See this answer for other options: How I can validate urls in C# for localhost.

编辑：根据源代码，您可以将 dataAnnotations：dataTypeAttribute：disableRegEx 添加到您的AppSettings中，并将其值设置为 true 。这将导致 UrlAttribute 验证过程仅 检查其是否以 http：// ， https：// 或 ftp：// 。请参阅第33行相同的源文件。

According to the source code, you could add dataAnnotations:dataTypeAttribute:disableRegEx to your AppSettings and set its value to true. This would cause the UrlAttribute validation process to only check that it begins with http://, https:// or ftp://. See Line 33 of the same source file for that.
