要在C# Web API中添加授权,可以使用OAuth 2.0授权框架来实现。首先需要安装Microsoft.AspNet.WebApi.OAuth包,并在WebApiConfig中配置OAuth授权。

以下是一个简单的示例:

首先在NuGet包管理器中安装Microsoft.AspNet.WebApi.OAuth包:

Install-Package Microsoft.AspNet.WebApi.OAuth

然后在WebApiConfig中配置OAuth授权:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // 配置OAuth授权
        config.SuppressDefaultHostAuthentication();
        config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));

        // 配置Web API路由
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

接下来,创建一个继承自OAuthAuthorizationServerProvider的类来实现OAuth授权逻辑:

public class CustomOAuthProvider : OAuthAuthorizationServerProvider
{
    public override async Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
    {
        context.Validated();
    }

    public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        // 验证用户名和密码
        if (context.UserName == "admin" && context.Password == "admin")
        {
            var identity = new ClaimsIdentity(context.Options.AuthenticationType);
            identity.AddClaim(new Claim(ClaimTypes.Name, context.UserName));
            context.Validated(identity);
        }
        else
        {
            context.SetError("invalid_grant", "The username or password is incorrect.");
            return;
        }
    }
}

最后在Global.asax.cs中注册OAuth授权服务:

protected void Application_Start()
{
    GlobalConfiguration.Configure(WebApiConfig.Register);

    // 配置OAuth授权服务
    var oAuthServerOptions = new OAuthAuthorizationServerOptions
    {
        AllowInsecureHttp = true,
        TokenEndpointPath = new PathString("/token"),
        AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),
        Provider = new CustomOAuthProvider()
    };

    app.UseOAuthAuthorizationServer(oAuthServerOptions);
    app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
}

这样就可以在C# Web API中添加授权,并使用Swagger进行文档化。
