asp.net - HttpServerUtility.UrlPathEncode 与 HttpServerUtility.UrlEncode

Question

HttpServerUtility.UrlPathEncode有什么区别和 HttpServerUtility.UrlEncode ?我什么时候应该选择一个？

Answer 1

更新:从 4.5 开始，根据 MSDN 引用，Microsoft 建议仅使用 UrlEncode。此外，先前在 MSDN 中列出的信息并未完全描述这两种方法的行为 - 请参阅注释。

区别在于空间转义 - UrlEncode 将它们转义为 + 符号，UrlPathEncode 将它们转义为 %20。 + 和 %20 仅当它们是 QueryString 部分的一部分时才等效 per W3C .所以你不能使用 + 号转义整个 URL，只有查询字符串部分。底线是 UrlPathEncode 总是更好 imho

You can encode a URL using with the UrlEncode() method or the UrlPathEncode() method. However, the methods return different results. The UrlEncode() method converts each space character to a plus character (+). The UrlPathEncode() method converts each space character into the string "%20", which represents a space in hexadecimal notation. Use the UrlPathEncode() method when you encode the path portion of a URL in order to guarantee a consistent decoded URL, regardless of which platform or browser performs the decoding.
