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。
