网址中的百分号编码

网址只允许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。 这些字符的编码方式以及要编码的字符完全取决于字符在网址结构中的位置。

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.
