asp.net - 如何在Azure端点中传递 header ..？

Question

我正在使用 Azure API ，URL 出现以下错误，请帮助解决此问题。请分享codesnip，如何更改web.config和端点。

The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'AzureApiManagementKey realm="https:/azure.azure-api.net/MethodName",name="Ocp-Apim-Subscription-Key",type="header"'.

我知道这仍然是一个非常古老的问题，我的回答将帮助面临同样问题的人。

解决方案是创建自定义端点行为，在其中将自定义消息处理程序添加到绑定(bind)参数。

在自定义消息处理程序中，请添加您的请求 header 。之后，使用任何绑定(bind)技术(如 basichttpsbinding 或 NetHttpsBinding)，安全模式为“Transport”，MessageEncoding 为“Text”来创建肥皂客户端对象。将自定义端点行为添加到soap客户端。

public class CustomEndpointBehavior : IEndpointBehavior
{
    public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    {
        bindingParameters.Add(new Func<HttpClientHandler, HttpMessageHandler>(x =>
        {
            return new CustomMessageHandler(x);
        }));
    }

    public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime) { }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher) { }

    public void Validate(ServiceEndpoint endpoint) { }
}

public class CustomMessageHandler : DelegatingHandler
{
    public CustomMessageHandler(HttpClientHandler handler)
    {
        InnerHandler = handler;
    }

    protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, System.Threading.CancellationToken cancellationToken)
    {
        request.Headers.Add("xxxx", "abcde");
        return base.SendAsync(request, cancellationToken);
    }
}

使用该服务的控制台应用程序。

static async Task Main(string[] args)
{
        var client = GetSOAPClient();

        try
        {
            var result = await client.MyOperation().ConfigureAwait(false);
            if(result.Body != null && result.Body.status == "Success")
            {
                Console.WriteLine(result.Body.myValue);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex?.Message);
        }

        Console.ReadKey();
    }

    static MyServiceClient GetSOAPClient()
    {
        NetHttpsBinding binding = new NetHttpsBinding();
        binding.Security.Mode = BasicHttpsSecurityMode.Transport;
        binding.MessageEncoding = NetHttpMessageEncoding.Text;
        EndpointAddress ea = new EndpointAddress(new Uri("https://myazureurl"));

        var client = new MyServiceClient(binding, ea);
        client.Endpoint.EndpointBehaviors.Add(new CustomEndpointBehavior());

        return client;
    }
}
