在ASP.NET Core 6 MVC中,Ocelot网关默认情况下不会将授权标头(例如Bearer令牌)传递给API路由。要解决此问题,您可以通过配置Ocelot中间件来启用授权标头的传递。以下是一个示例解决方法:
dotnet add package Ocelot.AspNetCore
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers();
services.AddOcelot()
.AddDelegatingHandler(); // 添加身份验证委托处理程序
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseRouting();
app.UseAuthentication(); // 添加身份验证中间件
app.UseOcelot().Wait(); // 使用Ocelot中间件
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
public class AuthenticationDelegatingHandler : DelegatingHandler
{
protected override async Task SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
// 从原始请求中获取身份验证标头
if (request.Headers.TryGetValues("Authorization", out var values))
{
var accessToken = values.First();
request.Headers.Add("Authorization", accessToken);
}
return await base.SendAsync(request, cancellationToken);
}
}
{
"ReRoutes": [
{
"DownstreamPathTemplate": "/api/{everything}",
"DownstreamScheme": "http",
"DownstreamHostAndPorts": [
{
"Host": "localhost",
"Port": 5000
}
],
"UpstreamPathTemplate": "/api/{everything}",
"UpstreamHttpMethod": [ "Get", "Post" ],
"AuthenticationOptions": {
"AuthenticationProviderKey": "Bearer",
"AllowedScopes": []
},
"RequiresAuthentication": true // 确保此属性设置为true
}
]
}
通过上述步骤,您就可以在ASP.NET Core 6 MVC中使用Ocelot网关,并确保授权标头(例如Bearer令牌)通过网关传递给API路由。
