Request.Querystring 从加密文本中删除字符

在我的应用程序中，我获取用户的电子邮件地址，对其进行加密、URLEncode，然后将其传递到查询字符串中。

email = Server.UrlEncode(aes.Encrypt(email));

登陆页面执行 Request.Querystring["email"]、UrlDecodes，然后解密。

    string email            = Server.UrlDecode(Request.QueryString["eId"]);
    string decemail         = aes.Decrypt(email);
    return decemail;

当“+”字符被删除时，发生了非常奇怪的行为，因此解密失败。

我尝试删除 UrlDecode，但这并没有解决问题。

解决问题的方法是这样做：

        string email            = Request.QueryString["eId"].ToString();
        string decemail         = aes.Decrypt(email);
        return decemail;

摆脱 UrlDecode，并在查询字符串上调用 ToString()。

有谁知道为什么会发生这种情况？ Request.QueryString默认调用urlDecode吗？我认为不会。

另外，为什么在这种情况下执行 .ToString() 会起作用？

原文

In my application I take a user's e-mail address, encrypt it, and URLEncode it, and pass it along into a QueryString.

email = Server.UrlEncode(aes.Encrypt(email));

The landing page does a Request.Querystring["email"], UrlDecodes it, and then decrypts it.

    string email            = Server.UrlDecode(Request.QueryString["eId"]);
    string decemail         = aes.Decrypt(email);
    return decemail;

Very strange behavior was happening where a "+" character was being removed and therefore the decryption was failing.

I attempted to remove the UrlDecode, but that didn't solve the problem.

What solved the problem was doing this:

        string email            = Request.QueryString["eId"].ToString();
        string decemail         = aes.Decrypt(email);
        return decemail;

Getting rid of UrlDecode, and calling a ToString() on the querystring.

Does anyone know why this would happen? Does Request.QueryString call urlDecode by default? I don't think it does.

Also, why would doing the .ToString() work in this instance?
