URL 对 C# 中的所有非字母数字进行编码

发布于 2024-09-05 21:45:24 字数 853 浏览 5 评论 0原文

我需要对电子邮件地址进行完全 URL 编码。

HttpUtility.UrlEncode 似乎忽略某些字符，例如！和。

我需要在格式如下的 url 中传递电子邮件地址：

/Users/[email protected]/Comments

因为我的 WebMethod uri 模板如下所示：

[WebGet(UriTemplate = "Users/{emailAddress}/Comments")]

句点会中断 WCF，并且不会将电子邮件地址传递给我的 REST Web 服务方法。删除句点就可以很好地传递该值。我希望有一种方法可以对所有非字母数字字符进行编码，因为使用该服务的所有内容都需要这样做。

编辑

我曾考虑使用：

Convert.ToBase64String(Encoding.ASCII.GetBytes("[email protected]"))

大多数其他语言都有简单的方法将字符串转换为base64吗？我主要担心的是，使用此服务的客户将需要使用 Java、PHP、Ruby 等对电子邮件地址进行编码。

I need to fully URL Encode an email address.

HttpUtility.UrlEncode seems to ignore certain characters such as ! and .

I need to pass an email address in a url formated like this:

/Users/[email protected]/Comments

Because my WebMethod uri template looks like this:

[WebGet(UriTemplate = "Users/{emailAddress}/Comments")]

The period breaks WCF and will not pass the email address to my REST webservice method.
Removing the period passes the value just fine. I'm hoping there is a method which will encode all non alpha numeric characters since everything consuming this service will need to do this.

EDIT

I had considered using:

Convert.ToBase64String(Encoding.ASCII.GetBytes("[email protected]"))

Do most other languages have easy ways to convert a string to base64? My main concern is that our customers who consume this service will need to encode the email address using Java, PHP, Ruby, etc.

这是您可以用来完成编码的潜在正则表达式。

Regex.Replace(s, @"[^\w]", m => "%" + ((int)m.Value[0]).ToString("X2"));

我不确定是否存在定义的现有框架方法来严格编码您可以向客户指出的所有非字母数字字符。

使用十六进制。有一个 ConvertTo 和一个 From 以及一个示例测试...

您还可以使用正则表达式将不匹配 A 到 Z 的字符转义，这样您的 URL 看起来仍然很漂亮。

它将返回一大串数字，所以你应该很好

        public static string ConvertToHex(string asciiString)
    {
        var hex = "";
        foreach (var c in asciiString)
        {
            int tmp = c;
            hex += String.Format("{0:x2}", Convert.ToUInt32(tmp.ToString()));
        }
        return hex;
    }

    public static string ConvertToString(string hex)
    {
        var stringValue = "";
        // While there's still something to convert in the hex string
        while (hex.Length > 0)
        {
            stringValue += Convert.ToChar(Convert.ToUInt32(hex.Substring(0, 2), 16)).ToString();
            // Remove from the hex object the converted value
            hex = hex.Substring(2, hex.Length - 2);
        }

        return stringValue;
    }

    static void Main(string[] args)
    {
        string hex = ConvertToHex("[email protected]");
        Console.WriteLine(hex);
        Console.ReadLine();
        string stringValue =
        ConvertToString(hex);
        Console.WriteLine(stringValue);
        Console.ReadLine();

    }

Use hex. There is a ConvertTo and a From and a sample test...

You can also just scape the characters that don't match A to Z by using a regex so your URL still looks pretty.

It will return a big list of numbers so you should be good

        public static string ConvertToHex(string asciiString)
    {
        var hex = "";
        foreach (var c in asciiString)
        {
            int tmp = c;
            hex += String.Format("{0:x2}", Convert.ToUInt32(tmp.ToString()));
        }
        return hex;
    }

    public static string ConvertToString(string hex)
    {
        var stringValue = "";
        // While there's still something to convert in the hex string
        while (hex.Length > 0)
        {
            stringValue += Convert.ToChar(Convert.ToUInt32(hex.Substring(0, 2), 16)).ToString();
            // Remove from the hex object the converted value
            hex = hex.Substring(2, hex.Length - 2);
        }

        return stringValue;
    }

    static void Main(string[] args)
    {
        string hex = ConvertToHex("[email protected]");
        Console.WriteLine(hex);
        Console.ReadLine();
        string stringValue =
        ConvertToString(hex);
        Console.WriteLine(stringValue);
        Console.ReadLine();

    }

除非我弄错了，否则 URL 编码只是百分号后跟 ASCII 数字（十六进制），所以这应该有效...

Dim Encoded as New StringBuilder()

For Each Ch as Char In "[email protected]"
    If Char.IsLetterOrDigit(Ch)
         Encoded.Append(Ch)
    Else
         Encoded.Append("%")
         Dim Byt as Byte = Encoding.ASCII.GetBytes(Ch)(0)
         Encoded.AppendFormat("{0:x2}", Byt)
    End If
Next

上面的代码结果为 something%2Bme%40example.com

Unless I am mistaken, URL Encoding is simply the percent sign followed by the ASCII number (in hex), so this should work...

Dim Encoded as New StringBuilder()

For Each Ch as Char In "[email protected]"
    If Char.IsLetterOrDigit(Ch)
         Encoded.Append(Ch)
    Else
         Encoded.Append("%")
         Dim Byt as Byte = Encoding.ASCII.GetBytes(Ch)(0)
         Encoded.AppendFormat("{0:x2}", Byt)
    End If
Next

The above code results in something%2Bme%40example.com
