如何在 Groovy 中对 URL 进行编码? [英] How to encode URL in Groovy?

问题描述

Groovy 中是否有一种 URLEncode?

我找不到任何字符串 → 字符串 URL 编码实用程序.

示例:脱氢酶(NADP+) → 脱氢酶%20(NADP%2b)

(+ 而不是 %20 也是可以接受的，因为 一些 实现这样做)

解决方案

你可以使用 java.net.URLEncoder.

在上面的例子中，括号也必须被编码:

def toEncode = "脱氢酶 (NADP+)"断言 java.net.URLEncoder.encode(toEncode, "UTF-8") == "脱氢酶+%28NADP%2B%29"

您还可以向字符串的元类添加一个方法:

String.metaClass.encodeURL = {java.net.URLEncoder.encode(委托，UTF-8")}

对任何字符串简单调用 encodeURL():

def toEncode = "脱氢酶 (NADP+)"断言 toEncode.encodeURL() == "脱氢酶+%28NADP%2B%29"

Is there a kind of URLEncode in Groovy?

I can't find any String → String URL encoding utility.

Example: dehydrogenase (NADP+) → dehydrogenase%20(NADP%2b)

(+ instead of %20 would also be acceptable, as some implementations do that)

解决方案

You could use java.net.URLEncoder.

In your example above, the brackets must be encoded too:

def toEncode = "dehydrogenase (NADP+)"
assert java.net.URLEncoder.encode(toEncode, "UTF-8") == "dehydrogenase+%28NADP%2B%29"

You could also add a method to string's metaclass:

String.metaClass.encodeURL = {
   java.net.URLEncoder.encode(delegate, "UTF-8")
}

And simple call encodeURL() on any string:

def toEncode = "dehydrogenase (NADP+)"
assert toEncode.encodeURL() == "dehydrogenase+%28NADP%2B%29"
