带结构的模板

注意如何使用 {{.FieldName}} 获得字段值。

package main

import (
    "fmt"
    "os"
    "text/template"
)

type Person struct {
    FirstName string
    LastName  string
    Street    string
    City      string
    State     string
    Zip       string
}

func main() {
    const (
        letter = `------------------------------
{{range .}}{{.FirstName}} {{.LastName}}
{{.Street}}
{{.City}}, {{.State}} {{.Zip}}

Dear {{.FirstName}},
    How are you?
{{end}}`
    )

    tmpl, err := template.New("letter").Parse(letter)
    if err != nil {
        fmt.Println(err.Error())
    }

    harry := Person{
        FirstName: "Harry",
        LastName:  "Jones",
        Street:    "1234 Main St.",
        City:      "Springfield",
        State:     "IL",
        Zip:       "12345-6789",
    }

    jane := Person{
        FirstName: "Jane",
        LastName:  "Sherman",
        Street:    "8511 1st Ave.",
        City:      "Dayton",
        State:     "OH",
        Zip:       "18515-6261",
    }

    tmpl.Execute(os.Stdout, []Person{harry, jane})
}

结果是：

1234 Main St.
Springfield, IL 12345-6789

Dear Harry,
    How are you?
Jane Sherman
8511 1st Ave.
Dayton, OH 18515-6261

Dear Jane,
    How are you?
