插入HTML到golang模板 [英] Inserting HTML to golang template
问题描述
< some_html>我在golang中有一个模板,其中有一个字符串,如下所示: {{.SomeOtherHTML}}< / some_html>
我期望的输出是这样的:
< some_html> < the_other_html /> < / some_html>
但我却看到类似这样的内容:
< some_html> &安培; LT; the_other_html /&安培; LT; < / some_html>
我也尝试插入一些JSON,但golang正在转义字符并添加诸如<$ c
如何在golang中插入HTML模板而不发生这种情况?
p>您应该将变量作为 template.HTML
传递,而不是 string
:
tpl:= template.Must(template.New main)。Parse(`{{defineT}} {{。Html}} {{。String}} {{end}}`))
tplVars:= map [string] interface {} {
Html:template.HTML(< p>段落< / p>),
字符串:< p>段落< / p>,
}
tpl.ExecuteTemplate(os.Stdout,T,tplVars)
// OUTPUT:< p>段落< / p>& lt; p& gt;段落&

正如您所看到的,我们作为 template.HTML
传递的变量不会被转义,而是作为字符串传递的变量
是。
I have a template in golang where I have a string that looks something like this:
<some_html> {{ .SomeOtherHTML }} </some_html>
I'm expecting an output to be something like this:
<some_html> <the_other_html/> </some_html>
But instead I'm seeing something like this:
<some_html> <the_other_html/< </some_html>
I'm also trying to insert some JSON but golang is escaping characters and adding things like "
in places they shouldn't be.
How do I insert into an HTML template in golang without this happening?
You should pass the variable as a template.HTML
and not as a string
:
tpl := template.Must(template.New("main").Parse(`{{define "T"}}{{.Html}}{{.String}}{{end}}`))
tplVars := map[string]interface{} {
"Html": template.HTML("<p>Paragraph</p>"),
"String": "<p>Paragraph</p>",
}
tpl.ExecuteTemplate(os.Stdout, "T", tplVars)
//OUTPUT: <p>Paragraph</p><p>Paragraph</p>
https://play.golang.org/p/QKKpQJ7gIs
As you can see, the variable we passed as a template.HTML
is not escaped, but the one passed as a string
is.
