解码带有百分比符号 (%HH) 的十六进制字符串

Question

我需要更改字符串：

Fast-9%20|%20Speed%20(Something-Cool)

为此：

Fast-9 | Speed (Something-Cool)

如何在 NodeJS 中实现？

Answer 1

参考decodeURIComponent

The decodeURIComponent() method decodes a Uniform Resource Identifier (URI) component previously created by encodeURIComponent or by a similar routine.

var str = 'Fast-9%20|%20Speed%20(Something-Cool)';
alert(decodeURIComponent(str));

Answer 2

试试这个：

var str = 'Fast-9%20|%20Speed%20(Something-Cool)';
str = str.replace(/%20/g, " ");
alert(str);

Answer 3

var decoded = decodeURIComponent("Fast-9%20|%20Speed%20(Something-Cool)");
