URL 中的百分号编码

允许URL只包含一定范围的字符。 任何超出该范围的字符都必须进行编码。 如何对这些字符进行编码,以及哪些字符要编码完全取决于字符在URL结构内的位置。

URLs are permitted to only contain a certain range of characters. Any character falling outside of that range must be encoded. How such characters are encoded, and which characters to encode depends entirely on where the character is located within the structure of the URL.
