让Dotnet识别Java发送来的自定义SoapHeader

    在异架构间通讯时，我们一般会采用WS。我遇到的情况是WSDL已经由AXIS生成，我需要用Dotnet实现服务器。

    简单实现后，发现里面的 NotifySOAPHeader 总是取不值，添加  SoapUnknownHeader[] 后，里面有值。可见是不能识别AXIS发送来的SoapHeader。

    仔细对比Dotnet生成的WSDL，和原来的定义的WSDL相关内容：

 

      <s:complexType name="NotifySOAPHeader">
        <s:sequence>
          <s:element minOccurs="0" maxOccurs="1" form="unqualified" name="spRevId" type="s:string" />
          <s:element minOccurs="0" maxOccurs="1" form="unqualified" name="spRevpassword" type="s:string" />
          <s:element minOccurs="0" maxOccurs="1" form="unqualified" name="spId" type="s:string" />
          <s:element minOccurs="0" maxOccurs="1" form="unqualified" name="SAN" type="s:string" />
          <s:element minOccurs="0" maxOccurs="1" form="unqualified" name="transactionId" type="s:string" />
          <s:element minOccurs="0" maxOccurs="1" form="unqualified" name="linkId" type="s:string" />
        </s:sequence>
        <s:anyAttribute />
      </s:complexType>

 

   <xsd:complexType name="NotifySOAPHeader">
        <xsd:sequence>
            <xsd:element name="spRevId" type="xsd:string" minOccurs="0" maxOccurs="1"/>
            <xsd:element name="spRevpassword" type="xsd:string" minOccurs="0" maxOccurs="1"/>            
            <xsd:element name="spId" type="xsd:string"/>
            <xsd:element name="SAN" type="xsd:string" minOccurs="0" maxOccurs="1"/>
            <xsd:element name="transactionId" type="xsd:string" minOccurs="0" maxOccurs="1"/>
            <xsd:element name="linkId" type="xsd:string" minOccurs="0" maxOccurs="1"/>
        </xsd:sequence>
    </xsd:complexType>

 

      我感觉只有一个区别，就是Dotnet生成的有：form="unqualified" ，而Java原来的没有。所以Dotnet不能识别有Prefix的NodeName，造成不能识别。例如： 

......
    <soapenv:Header>
        <NotifySOAPHeader xmlns="http://www.chinatelecom.com.cn/schema/ctcc/common/v2_1">
            <spId>07119935</spId>
            <spRevId>07119935</spRevId>
            <spRevpassword>vY95rHCNmj8JAeanlPhL8g==</spRevpassword>
        </NotifySOAPHeader>
    </soapenv:Header>
......

 

    <soapenv:Header>
        <NotifySOAPHeader xmlns="http://www.chinatelecom.com.cn/schema/ctcc/common/v2_1">
            <spId xmlns="">07119935</spId>
            <spRevId xmlns="">07119935</spRevId>
            <spRevpassword xmlns="">>vY95rHCNmj8JAeanlPhL8g==</spRevpassword>
        </NotifySOAPHeader>
    </soapenv:Header>

就因为有一个 xmlns=""，造成不能识别该SoapHeader。当然修正的方法也很简单，只要把NotifySOAPHeader的每个属性的元数据修改一下，像下面的示例：

    /// <remarks/>
    [System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://www.chinatelecom.com.cn/schema/ctcc/common/v2_1")]
    [System.Xml.Serialization.XmlRootAttribute("NotifySOAPHeader",Namespace = "http://www.chinatelecom.com.cn/schema/ctcc/common/v2_1", IsNullable = false)]
    public class NotifySOAPHeader : System.Web.Services.Protocols.SoapHeader
    {

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public string spRevId;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public string spRevpassword;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public string spId;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public string SAN;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public string transactionId;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public string linkId;
    }

修正为：

    [System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://www.chinatelecom.com.cn/schema/ctcc/common/v2_1")]
    [System.Xml.Serialization.XmlRootAttribute("NotifySOAPHeader",Namespace = "http://www.chinatelecom.com.cn/schema/ctcc/common/v2_1", IsNullable = false)]
    public class NotifySOAPHeader : System.Web.Services.Protocols.SoapHeader
    {

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Qualified)]
        public string spRevId;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Qualified)]
        public string spRevpassword;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Qualified)]
        public string spId;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Qualified)]
        public string SAN;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Qualified)]
        public string transactionId;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Qualified)]
        public string linkId;
    }

这样就可以了，不用再写代码从SoapUnknownHeader中取数据了。也没有必须为Java和Dotnet分别写一份代码。

是不是以后用Dotnet发布时，都用上这个声明呢？我经验不多，大家讨论一下。
