Golang GAE - HTML Template not inserting links properly into web page
问题
我正在使用Google App Engine上的Google Go。我正在将一个string描述保存到一个结构体中的datastore中，如下所示：
type Foo struct{
Bar string
}
该描述包含HTML标签，例如：
<a href="/">Bar</a>
我希望html模板在HTML文件中包含该描述，以便将其解析为HTML。例如：
<html><head><title>Title</title></head>
<body>{{.Bar}}</body></html>
解析为：
<html><head><title>Title</title></head>
<body><a href="/">Bar</a></body></html>
但是，实际上，我得到的是这样的：
<html><head><title>Title</title></head>
<body>&lt;a href=&#34;/&#34;&gt;Bar&#39;s&lt;/a&gt;</body></html>
如何使模板正确解析string为HTML链接？

I am using Google Go on Google App Engine. I am saving a string description in a structure into a datastore, like so:
type Foo struct{
Bar string
}
That description includes html tags, for example:
<a href="/">Bar</a>
I want the html template to include that description in an html file so it would be parsed as html. For example:
<html><head><title>Title</title></head>
<body>{{.Bar}}</body></html>
to be parsed as:
<html><head><title>Title</title></head>
<body><a href="/">Bar</a></body></html>
but instead, I get something like this:
<html><head><title>Title</title></head>
<body>&lt;a href=&#34;/&#34;&gt;Bar&#39;s&lt;/a&gt;</body></html>
How can I make the template parse the string correctly into an html link?

The "http/template" package automatically escapes all strings. To get around this you must make the value of type template.HTML. E.g.
import "html/template"
type Foo struct {
Bar template.HTML
}
And then in your code do something like:
Foo.Bar = template.HTML(barString)
