go template是个模板替换的包，如果是普通text就使用text/template，如果是html还有html/template，其实有过jsp开发经验的人对这个东西应该很容易上手，它比那些jstl表达式要简单很多。下面看看基本使用：
package main
import (
"text/template"
"os"
)
type ZHAO struct {
Name string
Email string
Array []string
}
func main() {
zhao_1 := ZHAO{"zhao", "[email protected]", []string{"1","12","12345"}}
zhao_2 := ZHAO{"lurongming", "[email protected]", []string{"he","llo","world"}}
t, _ := template.New("example").Parse("hello {{.}}\n")
t.Execute(os.Stdout, zhao_1)
t.Execute(os.Stdout, zhao_2)
}
输出结果为：
hello {zhao 823952051@qq.com [1 12 12345]}
hello {lurongming rongming_lu@163.com [he llo world]}
当然如果想对数据进行更复杂点的操作，可以通过独立的pipeline来处理数据。下面说一个复杂一点的用函数处理的例子：
package main
import (
"text/template"
"os"
"fmt"
)
type ZHAO struct {
Name string
Email string
Array []string
}
func show(zhao ZHAO) string {
return fmt.Sprintf("hello %s! an email: %s.", zhao.Name, zhao.Email)
}
func main() {
zhao_1 := ZHAO{"zhao", "[email protected]", []string{"1","12","12345"}}
zhao_2 := ZHAO{"lurongming", "[email protected]", []string{"he","llo","world"}}
t := template.New("example")
t = t.Funcs(template.FuncMap{"fun": show})
t, _ = t.Parse("{{.|fun}}\n")
t.ExecuteTemplate(os.Stdout, "example", zhao_1)
t.ExecuteTemplate(os.Stdout, "example", zhao_2)
}
输出结果为：
hello zhao! an email: [email protected].
hello lurongming! an email: [email protected].
