FileUtils.decodeUrl介绍

[英]Decodes the specified URL as per RFC 3986, i.e. transforms percent-encoded octets to characters by decoding with the UTF-8 character set. This function is primarily intended for usage with java.net.URL which unfortunately does not enforce proper URLs. As such, this method will leniently accept invalid characters or malformed percent-encoded octets and simply pass them literally through to the result string. Except for rare edge cases, this will make unencoded URLs pass through unaltered.
[中]按照RFC 3986解码指定的URL，即通过UTF-8字符集解码将百分比编码的八位字节转换为字符。此函数主要用于java。网不幸的是，该URL没有强制执行正确的URL。因此，此方法将宽容地接受无效字符或格式不正确的百分比编码八位字节，并将它们直接传递给结果字符串。除了极少数边缘情况外，这将使未编码的URL不受更改地通过。
