c# - 服务器.UrlEncode & 服务器.UrlDecode

Question

我不知道，为什么我们要使用 Server.UrlEncode() & Server.UrlDecode()？!在 QueryString 中我们看到 URL 中的任何内容，那么为什么我们要对它们进行编码或解码？

Answer 1

The URLEncode method applies URL encoding rules, including escape characters, to a specified string.

URLEncode converts characters as follows:

Spaces ( ) are converted to plus signs (+).

Non-alphanumeric characters are escaped to their hexadecimal representation.

此外，我认为您在谈论 HttpServerUtility.UrlDecode 方法，该方法解码编码字符串并返回原始字符串。

URL-decodes a string and returns the decoded string

URL encoding ensures that all browsers will correctly transmit text in URL strings. Characters such as a question mark (?), ampersand (&), slash mark (/), and spaces might be truncated or corrupted by some browsers. As a result, these characters must be encoded in tags or in query strings where the strings can be re-sent by a browser in a request string.

UrlDecode is a convenient way to access the HttpUtility.UrlDecode method at run time from an ASP.NET application. Internally, UrlDecode uses HttpUtility.UrlDecode to decode strings.
