通过HTTPS向WCF自托管REST服务发出POST请求的示例 [英] Example of a POST request to WCF selfhosted REST service over HTTPS

问题描述

关于SO的同一主题，这里有很多问题，但是似乎都没有一个完整的答案.我已经检查了大多数问题/答案，并进行了测试，测试和测试.因此，希望这个问题对我和其他挣扎中的人有帮助.

There are numerus question about the same topic here on SO, but none of them seems to give a complete answer. I have checked most of the questions/answers and tested, tested and tested. So hopefully this question will help me and others struggling.

问题.

如何设置可在https上运行的WCF自托管REST服务? 这就是我尝试设置服务和客户端的方式.它不起作用！但是我觉得每次更改都非常接近，但没有达到目标.

How do i set up WCF selfhosted REST service that works over https? This is how I have tried setting up the service and clients. It doesn't work! But i feel that im very close with every change, but im not reaching the goal.

那么，有人可以帮我一个完整的示例，该示例与REST端点，HTTPS上的自托管WCF和POST请求一起使用吗?我已经尝试过从各个地方弄乱一些零碎的东西，但我无法使它正常工作！ 我应该放弃吗?选择其他技术?

So, can someone help me with a complete example that is working with a REST endpoint, selfhosted WCF over HTTPS and a POST request? I have tried puzzling together bits and pieces from everywhere and i cant get it working! Should i give up? Choose another technology?

因此，一些代码:

[ServiceHost]

[ServiceHost]

        Uri uri = new Uri("https://localhost:443");

        WebHttpBinding binding = new WebHttpBinding(WebHttpSecurityMode.Transport);
        binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;

        using (ServiceHost sh = new ServiceHost(typeof(Service1), uri))
        {
            ServiceEndpoint se = sh.AddServiceEndpoint(typeof(IService1), binding, "");
            //se.EndpointBehaviors.Add(new WebHttpBehavior());

            // Check to see if the service host already has a ServiceMetadataBehavior
            ServiceMetadataBehavior smb = sh.Description.Behaviors.Find<ServiceMetadataBehavior>();
            // If not, add one
            if (smb == null)
                smb = new ServiceMetadataBehavior();
            smb.HttpGetEnabled = false; //**http**
            smb.HttpsGetEnabled = true; //**https**
            smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
            sh.Description.Behaviors.Add(smb);
            // Add MEX endpoint
            sh.AddServiceEndpoint(
              ServiceMetadataBehavior.MexContractName,
              MetadataExchangeBindings.CreateMexHttpsBinding(), //**https**
              "mex"
            );

            var behaviour = sh.Description.Behaviors.Find<ServiceBehaviorAttribute>();
            behaviour.InstanceContextMode = InstanceContextMode.Single;

            Console.WriteLine("service is ready....");
            sh.Open();

            Console.ReadLine();
            sh.Close();
        }

[IService]

[IService]

 [ServiceContract]
public interface IService1
{
    [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Xml, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest, UriTemplate = "Datarows_IN/")]
    [OperationContract]
    bool Save(BatchOfRows batchOfRows);
}

[服务]

[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)]
public class Service1 : IService1
{
    public bool Save(BatchOfRows batchOfRows)
    {
        Console.WriteLine("Entered Save");
        return true;
    }
}

[BatchOfRows]-简化

[BatchOfRows] - simplified

[DataContract]
public class BatchOfRows
{
    [DataMember]
    public int ID { get; set; } = -1;
    [DataMember]
    public string Data { get; set; } = "Hej";
}

这是在SO答案和Microsoft教程之后建立在SO答案之上的. 我什至不知道例子从哪里开始，其他例子从哪里结束. 我从这里开始: https://stackoverflow.com/a/57554374/619791 直到我尝试启用https之前，一切都很好，然后一切都停止了工作.

This is build upon SO answer after SO answer and Microsoft tutorials. I dont even know where what example started and the others ended. I began from this: https://stackoverflow.com/a/57554374/619791 And that worked very well until i tried enabling https, then everything stopped working.

这是我尝试过的一些客户端代码.

Here are some client code that i have tried.

[WebClient]

[WebClient]

            string uri = "https://localhost:443/Datarows_IN";
            WebClient client = new WebClient();
            client.Headers["Content-type"] = "application/json";
            client.Encoding = Encoding.UTF8;
            var b = new BatchOfRows();
            var settings = new JsonSerializerSettings() { DateFormatHandling = DateFormatHandling.MicrosoftDateFormat };

            string str2 = "{\"batchOfRows\":" + JsonConvert.SerializeObject(b, settings) + "}";
            string result = client.UploadString(uri, "POST", str2);

[HttpClient]

[HttpClient]

            string str2 = "{\"batchOfRows\":" + JsonConvert.SerializeObject(b, settings) + "}";
            var contentData = new StringContent(str2, System.Text.Encoding.UTF8, "application/json");
            //string result = client.UploadString(uri, "POST", str2);
            //HttpResponseMessage response = client.PostAsJsonAsync("https://localhost:443/Datarows_IN", b).GetAwaiter().GetResult();
            HttpResponseMessage response = client.PostAsync("https://localhost:443/Datarows_IN", contentData).GetAwaiter().GetResult();
            response.EnsureSuccessStatusCode();

[ChannelFactory] ​​

[ChannelFactory]

            //var c = new ChannelFactory<IService1>(binding, new EndpointAddress("https://localhost:443/Datarows_IN"));
            var c = new ChannelFactory<IService1>(binding, new EndpointAddress("https://localhost:443/"));
            ((WebHttpBinding)c.Endpoint.Binding).Security.Mode = WebHttpSecurityMode.Transport;
            ((WebHttpBinding)c.Endpoint.Binding).Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
            c.Endpoint.Behaviors.Add(new WebHttpBehavior());
            var aw = c.CreateChannel();

            var b = new ModuleIntegration.Client.Objects.BatchOfRows();
            aw.Save(b);

没有一个客户在工作.如果我调试，则永远不会触发服务端点. 这是即时通讯收到的当前错误:

None of the clients work. If i debug my Service endpoint is never triggered. This is the current error that im getting:

<Fault xmlns="http://schemas.microsoft.com/ws/2005/05/envelope/none">
    <Code>
        <Value>Sender</Value>
        <Subcode>

        <Text xml:lang="sv-SE">The message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher.

    </Reason>
</Fault>

请帮助！为什么这么难?！?

Please help! Why is this so hard?!?

推荐答案

您的服务缺少

Your service is missing the WebHttpBehavior.

没有它，WebInvoke属性什么也不做，并且路径"Datarows_IN"无法识别为动作.

Without it, the WebInvoke attribute does nothing, and the path "Datarows_IN" is not recognized as an action.

以下是完整的(对我有用)服务主机代码:

Here's the full (works for me) service host code:

var binding = new WebHttpBinding()
{
    Security = {
        Mode = WebHttpSecurityMode.Transport
    }
};
var baseUri = new Uri("https://localhost:443");

using (ServiceHost sh = new ServiceHost(typeof(Service1), baseUri))
{
    var metadata = sh.Description.Behaviors.Find<ServiceMetadataBehavior>();
    if (metadata == null) {
        metadata = new ServiceMetadataBehavior();
        sh.Description.Behaviors.Add(metadata);
    }
    metadata.HttpsGetEnabled = true;

    var endpoint = sh.AddServiceEndpoint(typeof(IService1), binding, "/");
    endpoint.EndpointBehaviors.Add(new WebHttpBehavior());

    Console.WriteLine("Service is ready....");
    sh.Open();

    Console.WriteLine("Service started. Press <ENTER> to close.");
    Console.ReadLine();
    sh.Close();
}
