如何取消对HTML字符串中的引号进行转义

Question

I have a string in Go as follow:

Hello world ! <a href=\"www.google.com\">Google</a>

the quotes was escaped, and I want to get the string without backward slash.

I tried to use the html.UnescapeString but not what I want. Is there any solution about my question.

Assuming you are using html/template, you either want to store the whole thing as a template.HTML, or store the url as a template.URL. You can see how to do it here: https://play.golang.org/p/G2supatMfhK

tplVars := map[string]interface{}{
    "html": template.HTML(`Hello world ! <a href="www.google.com">Google</a>"`),
    "url": template.URL("www.google.com"),
    "string": `Hello world ! <a href="www.google.com">Google</a>"`,

}
t, _ := template.New("foo").Parse(`
{{define "T"}}
    Html: {{.html}}
    Url: <a href="{{.url}}"/>
    String: {{.string}}
{{end}}
`)
t.ExecuteTemplate(os.Stdout, "T", tplVars)

//Html: Hello world ! <a href="www.google.com">Google</a>"
//Url: <a href="www.google.com"/>
//String: Hello world ! &lt;a href=&#34;www.google.com&#34;&gt;Google&lt;/a&gt;&#34;
