测试WCF时未列出服务

Question

我正在尝试为正在制作的网站测试WCF服务。 我正在使用jQuery调用服务（ $.getJSON() ），但是我在网站上不断收到Connection Refused Error。

因此，我签出了部署到计算机时创建的网站，甚至没有列出我的方法“ GetData（）”。 它仅列出服务本身的名称。 我一般来说对使用WCF还是比较陌生，所以请留意：'）在Windows Studio打开我的服务的测试客户端中，甚至没有列出：

当我尝试添加它时，它表示服务已成功添加，但未显示任何内容。 今天早些时候，我在列表中看到了这些方法，但是由于我搞砸了，所以不得不删除整个项目。

Web.config看起来像这样：

<?xml version="1.0"?>
<configuration>

    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />

</configuration>

接口：

[ServiceContract]
public interface ExampleServiceInterface
{
    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json)]
    String GetData();

    [OperationContract]
    CompositeType GetDataUsingDataContract(CompositeType composite);
}


[DataContract]
public class CompositeType
{
    bool boolValue = true;
    string stringValue = "Hello ";

    [DataMember]
    public bool BoolValue
    {
        get { return boolValue; }
        set { boolValue = value; }
    }

    [DataMember]
    public string StringValue
    {
        get { return stringValue; }
        set { stringValue = value; }
    }
}

服务：

public class ExampleService : ExampleServiceInterface
{
    public String GetData()
    {
        Random ran = new Random();
        TestClass[] tc = new TestClass[5];
        TestClass tc1 = new TestClass();
        tc1.TheText = "First Text " + ran.Next();
        tc1.TheOtherText = "First Other Text " + ran.Next();
        TestClass tc2 = new TestClass();
        tc2.TheText = "Second Text " + ran.Next();
        tc2.TheOtherText = "Second Other Text " + ran.Next();
        TestClass tc3 = new TestClass();
        tc3.TheText = "Third Text " + ran.Next();
        tc3.TheOtherText = "Third Other Text " + ran.Next();
        TestClass tc4 = new TestClass();
        tc4.TheText = "Fourth Text " + ran.Next();
        tc4.TheOtherText = "Fourth Other Text " + ran.Next();
        TestClass tc5 = new TestClass();
        tc5.TheText = "Fifth Text " + ran.Next();
        tc5.TheOtherText = "Fifth Other Text " + ran.Next();

        tc[0] = tc1;
        tc[1] = tc2;
        tc[2] = tc3;
        tc[3] = tc4;
        tc[4] = tc5;

        return JsonConvert.SerializeObject(tc);
    }

    public CompositeType GetDataUsingDataContract(CompositeType composite)
    {
        if (composite == null)
        {
            throw new ArgumentNullException("composite");
        }
        if (composite.BoolValue)
        {
            composite.StringValue += "Suffix";
        }
        return composite;
    }
}

最后，出于良好的考虑，这是我使用的jQuery：

$(function() {
    $("input:button").click(function() {
        $.getJSON("http://localhost:52535/ExampleService.svc/GetData?callback=?", function(data) {
            alert(data);
        });
    });
});

Answer 1

首先，如果您从中更改webInvoke属性，将会更好：

[OperationContract]
[WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json)]
String GetData();

对此：

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate="/getData")]
String GetData();

比运行您的服务并通过编写url这样在浏览器中打开它：

http://host_name:port_number/service_name.svc/getData

之后，您应该获取数据（如果一切都OK）

当我尝试添加它时，它表示服务已成功添加，但未显示任何内容。 今天早些时候，我在列表中看到了这些方法，但是由于我搞砸了，所以不得不删除整个项目。

我认为这是由于在Web配置文件中设置的webHttpBinding（使您的服务稳定）引起的。 通常，测试客户端会为SOAP服务生成调用方法。

Answer 2

（想写评论，但要花很长时间...）要创建一个简单的REST服务，您必须执行一些步骤：

1）定义服务方法和接口：

namespace CoreAuroraService.Services
{
    [DataContract]
    public class Patient 
    {
        [DataMember]
        public String LastName{get;set;}

        [DataMember]
        public string FirstName{get;set;}
    }

    [ServiceContract]
    public interface IPatientService
    {
        [OperationContract]
        [WebGet(UriTemplate = "/GetAllPatients", ResponseFormat = WebMessageFormat.Json)]
        List<Patient> GetAllPatients();

        [OperationContract]
        [WebInvoke(UriTemplate = "/Create", Method = "POST", ResponseFormat = WebMessageFormat.Json)]
        bool CreatePatient();


        [OperationContract]
        [WebInvoke(UriTemplate = "/Update", Method = "PUT", ResponseFormat = WebMessageFormat.Json)]
        bool UpdatePatient(Guid patientGuid);


        [OperationContract]
        [WebInvoke(UriTemplate = "/Delete", Method = "DELETE", ResponseFormat = WebMessageFormat.Json)]
        bool DeletePatient(Guid patientGuid);
    }

    public class PatientService : IPatientService
    {
        public List<Patient> GetAllPatients()
        {
            var patient = new Patient() { FirstName = "Jeem", LastName = "Street" };
            var patients = new List<Patient> { patient };
            return patients;
        }

        public bool CreatePatient()
        {
            // TODO: Implement the logic of the method here
            return true;
        }

        public bool UpdatePatient(Guid patientGuid)
        {
            // TODO: Implement the logic of the method here
            return true;
        }

        public bool DeletePatient(Guid patientGuid)
        {
            // TODO: Implement the logic of the method here
            return true;
        }
    }
}

2）现在，您必须定义服务的行为。 为此，您必须在服务项目中更改配置文件。 在此文件中，您必须定义服务行为以及使您的服务稳定的其他设置。 为此，将下一个代码粘贴到serviceModel块中：

<services>
  <service name="CoreAuroraService.Services.PatientService">
    <endpoint address="" behaviorConfiguration="rest" binding="webHttpBinding" bindingConfiguration="maxStream" contract="CoreAuroraService.Services.IPatientService">
      <identity>
        <dns value="localhost"/>
      </identity>
    </endpoint>
    <host>
      <baseAddresses>
        <add baseAddress="https://localhost/Services/PatientService.svc"/>
      </baseAddresses>
    </host>
  </service>
</services>

<behaviors>
  <endpointBehaviors>
    <behavior name="rest">
      <webHttp helpEnabled="true"/>
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior>
      <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

3）现在，让我们编写一个方法，该方法将从javascript调用我们的服务：

<script>
    function GetP() {
        // Now I need to send cross domain request to the service because my services hosted in another project
        // Tested in IE 11
        var url = "http://localhost:29358/Services/PatientService.svc/GetAllPatients";
        $.ajax({
            type: 'GET',
            dataType: "text",
            url: url,
            success: function (responseData, textStatus, jqXHR) {
                console.log("in");
                var data = JSON.parse(responseData);
                console.log(data);
            },
            error: function (responseData, textStatus, errorThrown) {
                alert('POST failed.');
            }
        });
    }
</script>
