go - 如何使用beego的本地化？

Question

我尝试使用 i18n 但它无法工作 i18n 在下面。 http://beego.me/docs/module/i18n.md

路由器/init.go：

// Initialized language type list.
langs := strings.Split(models.Cfg.MustValue("lang", "types"), "|")
names := strings.Split(models.Cfg.MustValue("lang", "names"), "|")
langTypes = make([]*langType, 0, len(langs))
for i, v := range langs {
    langTypes = append(langTypes, &langType{
        Lang: v,
        Name: names[i],
    })
}

for _, lang := range langs {
    beego.Trace("Loading language: " + lang)
    if err := i18n.SetMessage(lang, "conf/"+"locale_"+lang+".ini"); err != nil {
        beego.Error("Fail to set message file: " + err.Error())
        return
    }
}

路由器/router.go

// Initialized language type list.
langs := strings.Split(models.Cfg.MustValue("lang", "types"), "|")
names := strings.Split(models.Cfg.MustValue("lang", "names"), "|")
langTypes = make([]*langType, 0, len(langs))
for i, v := range langs {
    langTypes = append(langTypes, &langType{
        Lang: v,
        Name: names[i],
    })
}

for _, lang := range langs {
    beego.Trace("Loading language: " + lang)
    if err := i18n.SetMessage(lang, "conf/"+"locale_"+lang+".ini"); err != nil {
        beego.Error("Fail to set message file: " + err.Error())
        return
    }
}

我只是复制和粘贴。

这是我的完整代码。 https://github.com/shinriyo/sample_i18n

我想知道最低代码。

这是错误

我发现的最好方法是：

在 conf/ 文件夹中创建翻译文件
在 conf/app.conf 中配置您的翻译列表。我的语言是 en-US 和 pt-BR
```
lang_types = "en-US|pt-BR"
```

使用此代码在 controller/baseController/ 文件夹中创建文件 baseController.go

package controllers
import (
      "github.com/astaxie/beego"
      "github.com/beego/i18n"
      "strings"
)
var langTypes []string // Languages that are supported.
// baseController represents base router for all other app routers.
// It implemented some methods for the same implementation;
// thus, it will be embedded into other routers.
type BaseController struct {
    beego.Controller // Embed struct that has stub implementation of the                     interface.
    i18n.Locale      // For i18n usage when process data and render template.
}

func init() {
    beego.AddFuncMap("i18n", i18n.Tr)

    // Initialize language type list.
    langTypes = strings.Split(beego.AppConfig.String("lang_types"), "|")

    // Load locale files according to language types.
    for _, lang := range langTypes {
        beego.Trace("Loading language: " + lang)
        if err := i18n.SetMessage(lang, "conf/"+"locale_"+lang+".ini"); err != nil {
            beego.Error("Fail to set message file:", err)
            return
        }
    }
}

// Prepare implemented Prepare() method for baseController.
// It's used for language option check and setting.
func (this *BaseController) Prepare() {
    // Reset language option.
    this.Lang = "" // This field is from i18n.Locale.
    beego.Trace("running prepare")
    // 1. Get language information from 'Accept-Language'.
    al := this.Ctx.Request.Header.Get("Accept-Language")
    if len(al) > 4 {
        al = al[:5] // Only compare first 5 letters.
        if i18n.IsExist(al) {
            this.Lang = al
        }
    }

    beego.Trace("Accept-Language is " + al)
    // 2. Default language is English.
    if len(this.Lang) == 0 {
        this.Lang = "en-US"
    }

    // Set template level language option.
    this.Data["Lang"] = this.Lang
}

在其他控制器中使用您的自定义 BaseController。

package controllers

import (
    bc "github.com/myFirstApp/controllers/baseController"
)

type LoginController struct {
    bc.BaseController
}

func (c *LoginController) Get() {
    c.TplNames = "login.tpl"
}

在模板中使用 i18n
```
{{i18n .Lang "login.capitalized"}}
```

我的 locale_en-US.ini

    login = login
    [login]
    uppercase = LOGIN
    capitalized = Login

package controllers

import (
    "github.com/astaxie/beego"
    "github.com/beego/i18n"
    "os"
    "strings"
)

type BaseController struct {
    beego.Controller
}

func (b *BaseController) settingLocales() {
    // load locales with locale_LANG.ini files
    langs := "en-US|zh-CN"
    for _, lang := range strings.Split(langs, "|") {
        lang = strings.TrimSpace(lang)
        files := []string{"conf/" + "locale_" + lang + ".ini"}
        if fh, err := os.Open(files[0]); err == nil {
            fh.Close()
        } else {
            files = nil
        }
        if err := i18n.SetMessage(lang, "conf/"+"locale_"+lang+".ini", files...); err != nil {
            beego.Error("Fail to set message file: " + err.Error())
            os.Exit(2)
        }
    }
    Las := i18n.ListLangs()
    beego.Debug("langs:", Las)
}

func (b *BaseController) Get() {
    b.settingLocales()
    if i18n.IsExist("en-US") {
        b.Data["json"] = i18n.Tr("en-US", "hi")
    } else {
        b.Data["json"] = s
    }
    b.ServeJson()
}

在 conf/ 中创建文件 locale_en-US.ini 和 locale_zh-CN.ini

在 locale_en-US.ini 中，例如：

hi = hello
bye = goodbye
