wcf第3步之报文分析及原生调用

2024-08-17 17:50:50 222人阅读

最简单的调用当然是服务引用,但是我更想原生调用,所以希望能通过报文有如下研究

1.报文分析

<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:wsa10="http://www.w3.org/2005/08/addressing" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://tempuri.org/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" name="DemoService" targetNamespace="http://tempuri.org/">
<wsdl:types>
<xsd:schema targetNamespace="http://tempuri.org/Imports">

</xsd:schema>
</wsdl:types>
<wsdl:message name="IDemoService_DoSomething_InputMessage">

</wsdl:message>
<wsdl:portType name="IDemoService">
<wsdl:operation name="DoSomething">
<wsdl:input wsaw:Action="http://tempuri.org/IDemoService/DoSomething" message="tns:IDemoService_DoSomething_InputMessage"/>
<wsdl:output wsaw:Action="http://tempuri.org/IDemoService/DoSomethingResponse" message="tns:IDemoService_DoSomething_OutputMessage"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="BasicHttpBinding_IDemoService" type="tns:IDemoService">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="DoSomething">
<soap:operation soapAction="http://tempuri.org/IDemoService/DoSomething" style="document"/>
<wsdl:input>
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="DemoService">
<wsdl:port name="BasicHttpBinding_IDemoService" binding="tns:BasicHttpBinding_IDemoService">
<soap:address location="http://dev.xxx.io/Demo/DemoService.svc"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>

可以看到

1.wcf服务地址

http://dev.xxx.io/Demo/DemoService.svc

2.引用了4个命名空间

Serialization

Contracts.Models.Demo

DataTypes

System

3.Service的名称及接口

DemoService,
IDemoService

4.服务接口的方法 
DoSomething



再访问

来读取类型的具体字段
http://dev.xxx.io/Demo/DemoService.svc?xsd=xsd3

根据以上信息,可以生成的最简单的 Contract代码如下:

[Serializable]
    [DataContract(Name = "Response", Namespace = "http://schemas.datacontract.org/2004/07/DataType")]
    
    public class Response  
    {
       [DataMember]
        public int ErrorCode { get; set; }
      [DataMember]
        public string Message { get; set; }
      [DataMember]
        public bool Success { get; set; }
    }

    /// <summary>
    /// SomeResponse
    /// </summary>
    [DataContract(Name = "SomeResp", Namespace = "http://schemas.datacontract.org/2004/07/DataType")]
   
    [Serializable]
    public sealed class SomeResp : Response
    {
        /// <summary>
        /// 时间格式的Date
        /// </summary>
       [DataMember]
        public DateTime Date { get; set; }

        /// <summary>
        /// 格式成字符串的时间
        /// </summary>
       [DataMember]
        public string DateStr { get; set; }

        /// <summary>
        /// 返回传入的Date
        /// </summary>
       [DataMember]
        public string ResultDate { get; set; }

        /// <summary>
        /// 返回传入的Date
        /// </summary>
      [DataMember]
        public string ResultDateUTC { get; set; }
    }

    [Serializable]

    [DataContract(Name = "Request", Namespace = "http://schemas.datacontract.org/2004/07/Contracts.Models.Demo")]
    public class Request
    {
        [DataMember]
        public string UserId { get; set; }
    }

    /// <summary>
    /// SomeRequest
    /// </summary>
    [DataContract(Name = "SomeReq", Namespace = "http://schemas.datacontract.org/2004/07/Contracts.Models.Demo")]
    [Serializable]
    
    public sealed class SomeReq : Request
    {
        /// <summary>
        /// 时间
        /// </summary>
        [DataMember]
        public DateTime Date { get; set; }

        /// <summary>
        /// Data
        /// </summary>
        [DataMember]
        public DateTimeOffset DateUTC { get; set; }


    }

    /// <summary>
    /// IDemoService
    /// </summary>
    [ServiceContract ]
   
    public interface IDemoService
    {
        /// <summary>
        /// Does something.
        /// </summary>
        /// <param name="request">The request.</param>
        /// <returns></returns>
        [OperationContract ]
        SomeResp DoSomething(SomeReq request);
    }

具体调用代码如下:

using System.Runtime.Serialization;
using System.ServiceModel;

EndpointAddress address = new EndpointAddress("http://dev.xxx.io/Demo/DemoService.svc?wsdl");
            BasicHttpBinding binding = new BasicHttpBinding();
            ChannelFactory<IDemoService> factory = new ChannelFactory<IDemoService>(binding, address);
            IDemoService channel = factory.CreateChannel();
            
            var result = channel.DoSomething(new SomeReq()
            {
                Date = DateTime.Now
            });
