Localization 本地化

IGeekFan.Localization.FreeSql

基于数据库存储的本地化，可以让你的程序支持多语言，会创建二个表。

LocalCulture(本地化语言)

类型	名称	长度
long	Id	11
string	Name	50
string	DisplayName	50

LocalResource(资源)

类型	名称	长度
long	Id	11
string	Key	50
string	Value	500
long	CultureId	11

可支持自定义长度，通过FluentAPI进行设置

安装包

dotnet add package IGeekFan.Localization.FreeSql
dotnet add package FreeSql.Provider.Sqlite

配置FreeSql服务

定义扩展方法

public static IServiceCollection AddFreeSql(this IServiceCollection services, IConfiguration c)
{
    IFreeSql fsql = new FreeSqlBuilder()
                .UseConnectionString(DataType.Sqlite, c["ConnectionStrings:DefaultConnection"])
                .UseAutoSyncStructure(true)
                .UseNameConvert(NameConvertType.PascalCaseToUnderscoreWithLower)
                .UseMonitorCommand(
                    cmd => Trace.WriteLine("\r\n线程" + Thread.CurrentThread.ManagedThreadId + ": " + cmd.CommandText)
                ).Build();

    services.AddSingleton(fsql);

    return services;
}

appsettings.json

  "ConnectionStrings": {
    "DefaultConnection": "Data Source=|DataDirectory|\\web.db;"
  }

Program.cs配置服务

builder.Services.AddFreeSql(c);

替换默认的IStringLocalizerFactory

builder.Services.AddSingleton<IStringLocalizerFactory, FreeSqlStringLocalizerFactory>(); 
builder.Services.TryAddTransient(typeof(IStringLocalizer<>), typeof(StringLocalizer<>));

中间件引用

var supportedCultures = new List<CultureInfo>
{
    new("en-US"),
    new("ja-JP"),
    new("fr-FR"),
    new("zh-CN")
};
var options = new RequestLocalizationOptions
{
    DefaultRequestCulture = new RequestCulture("zh-CN"),
    SupportedCultures = supportedCultures,
    SupportedUICultures = supportedCultures
};
app.UseRequestLocalization(options);

增加一些默认数据

 public static class CodeFirstExtension
    {
        public static ICodeFirst SeedData(this ICodeFirst @this)
        {
            @this.Entity<LocalCulture>(e =>
            {
                e.HasData(new List<LocalCulture>()
                    {
                        new("en-US","en-US") ,
                        new("ja-JP","ja-JP")
                        {
                            Resources=new List<LocalResource>()
                            {
                                new("Hello","こんにちは"),
                                new("Request Localization Sample","リクエストローカライズ"),
                            }
                        },
                        new("fr-FR","fr-FR")
                        {
                            Resources=new List<LocalResource>()
                            {
                                new("Hello","Bonjour"),
                                new("Request Localization Sample","Demander un échantillon localisé"),
                            }
                        },
                        new("zh-CN","中文")
                        {
                            Resources=new List<LocalResource>()
                            {
                                new("Hello","你好"),
                                new("Request Localization Sample","请求资源示例"),
                            }
                        }
                    });
            });
            return @this;
        }
    }

在fsql定义中增加此方法的引用

+ fsql.CodeFirst.SeedData();
services.AddSingleton(fsql);

[Route("[controller]/[action]")]
public class CultureController : Controller
{      
    private readonly ILogger<CultureController> _logger;
    private readonly IStringLocalizer<CultureController> _stringLocalizer;

    public CultureController(ILogger<CultureController> logger, IStringLocalizer<CultureController> stringLocalizer)
    {
        _logger = logger;
        _stringLocalizer = stringLocalizer;
    }
    
    [HttpGet]
    public string Hello()
    {
        return _stringLocalizer["Hello"];
    } 
}
