go - 如何使用beego的localize？

Question

我尝试使用 i18n 但它不起作用i18n 在下面。 http://beego.me/docs/module/i18n.md

routers/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

我想知道最少的代码。

Answer 1

我发现的最好的方法是:

1. 在 conf/文件夹中创建翻译文件

2. 在 conf/app.conf 配置你的翻译列表。我的语言是 en-US 和 pt-BR

   lang_types = "en-US|pt-BR"
   

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

   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
   }
   

4. 在其他 Controller 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"
   }
   

5. 在模板中使用 i18n

   {{i18n .Lang "login.capitalized"}}
   

我的 locale_en-US.ini

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