函数

func EscapeString

1

func EscapeString(s string) string

EscapeString escapes special characters like “<” to become “<”. It escapes only five such characters: <, >, &, ' and ". UnescapeString(EscapeString(s)) == s always holds, but the converse isn’t always true.

​ EscapeString用于转义HTML文本中的特殊字符，例如将"<“转义为”<"。它只转义五个特殊字符： <, >, &, ' 和 "。UnescapeString(EscapeString(s)) == s 总是成立，但反过来不一定成立。

package main

import (
	"fmt"
	"html"
)

func main() {
	const s = `"Fran & Freddie's Diner" <tasty@example.com>`
	fmt.Println(html.EscapeString(s))
}

Output:

&#34;Fran &amp; Freddie&#39;s Diner&#34; &lt;tasty@example.com&gt;

func UnescapeString

1

func UnescapeString(s string) string

UnescapeString unescapes entities like “<” to become “<”. It unescapes a larger range of entities than EscapeString escapes. For example, “á” unescapes to “á”, as does “á” and “á”. UnescapeString(EscapeString(s)) == s always holds, but the converse isn’t always true.

​ UnescapeString用于反转义实体，例如将"<“反转义为”<"。它比EscapeString转义更多的实体。例如，"á“反转义为”á"，"á“和”á“也是如此。UnescapeString(EscapeString(s)) == s 总是成立，但反过来不一定成立。

Output:

"Fran & Freddie's Diner" <tasty@example.com>
