asp.net core ABP模板本地化设置

ABP的语言本地化设置非常方便，甚至地区图标ABP框架都已经有了。

先看看结果吧。

英文的界面

中文的界面

配置流程如下：

首先在Localization目录下新建一个对应的json文件，里面存放对应变量的本地化字符串，命名规则就是 应用名-本地化简称.json

比如我的应用名叫做SimpTaskApp(没错，就是abp的入门教程的工程)，然后中文的简写是zh，所以我的json文件就是SimpleTaskApp-zh.json。

然后来看看内容

json里主要是两个属性culture和texts。

culture对应文化的简称。中文zh   英文en 土耳其文tr

texts对应字符串变量。

这里配置好以后就在XXXLocalizationConfigurer.cs里添加语言。XXX是应用名

位置在这里。

localizationConfiguration.Languages集合里添加一个LanguageInfo对象，参数3个，第一个是语言简写，如中文是zh，第二个是显示的名称，第三个是图标，一般是国家或地区的标志，规则是famfamfam-flags XX，XX是国家或地区的简写，如中国 cn

这段就是那个下拉选择语言的前端代码，遍历Model里的Language集合，加入下拉菜单。

 @model Acme.SimpleTaskApp.Web.Views.Shared.Components.LanguageSelection.LanguageSelectionViewModel
 <li class="dropdown">
     <a href="#" class="dropdown-toggle" data-toggle="dropdown">
         <div class="@Model.CurrentLanguage.Icon"></div>
         <span>@Model.CurrentLanguage.DisplayName</span>
         <b class="caret"></b>
     </a>
     <ul class="dropdown-menu">
         @foreach (var language in Model.Languages)
         {
             if (language.Name != Model.CurrentLanguage.Name)
             {
                 <li><a href="@Url.Action("ChangeCulture", "AbpLocalization")?cultureName=@(language.Name)&returnUrl=@(Model.CurrentUrl)"><div class="@language.Icon"></div> @language.DisplayName</a></li>
             }
         }
     </ul>
 </li>

最后的效果就如下
