Question

我尝试使用带有以下数据的jquery ajax POST来调用WCF服务：

数据= ＆＃34; {\＆＃34; StudentID \＆＃34;：\＆＃34; 18 \＆＃34; \＆＃34;消息\＆＃34;：{\＆＃34;头\＆＃34;：{\＆＃34; EMAILID \＆＃34;：\＆＃34; 0 \＆＃34; \＆＃34;由\＆＃34;：{\＆＃34;地址类型\＆＃34;：\＆＃34; 0 \＆＃34; \＆＃34; AliasType \＆＃34;：\＆＃34; 0 \＆＃34; \＆＃34;名称\＆＃34 ;：\＆＃34; 教师\＆＃34; \＆＃34; StudentID \＆＃34;：\＆＃34; 18 \＆＃34; \＆＃34; SymbolURL \＆＃34;：\＆＃34;老师。 PNG \＆＃34; \＆＃34;地址\＆＃34;：\＆＃34; 18 \＆＃34;}，\＆＃34;为了\＆＃34;：{\＆＃34;地址类型\＆＃34;：\＆＃34; 0 \＆＃34; \＆＃34; AliasType \＆＃34;：\＆＃34; 0 \＆＃34; \＆＃34;名称\ ＆＃34;：\＆＃34;伊恩 \＆＃34; \＆＃34; StudentID \＆＃34;：\＆＃34; 346 \＆＃34; \＆＃34; SymbolURL \＆＃34;：\＆＃34; \＆＃ 34; \＆＃34;地址\＆＃34;：\＆＃34; 346 \＆＃34;}，\＆＃34; TimeRecieved \＆＃34;：\＆＃34; /日期（0） / \＆＃34;}，\＆＃34;版本\＆＃34;：\＆＃34; 1 \＆＃34; \＆＃34; MailMessageXML \＆＃34;：\＆＃34; \ ＆＃34; \＆＃34; CompressedBody \＆＃34;：\＆＃34; \＆＃34;}，\＆＃34;映像文件名称\＆＃34;：\＆＃34; \＆＃34 ;}＆＃34;

我收到错误（回复正文）：

{＆＃34; ExceptionDetail＆＃34; {＆＃34; HELPLINK＆＃34;：空，＆＃34;的InnerException＆＃34; {＆＃34; HELPLINK＆＃34;：空，＆＃34;的InnerException＆＃34; {＆＃34; HELPLINK＆＃34;：空，＆＃34;的InnerException＆＃34;：空，＆＃34;消息＆＃34;：＆＃34;的意外文件结尾。＆＃34;，＆＃34; StackTrace＆＃34;：＆＃34;在 System.Xml.EncodingStreamWrapper.ReadBOMEncoding（布尔 notOutOfBand）\ u000d \ u000a at System.Xml.EncodingStreamWrapper..ctor（Stream stream，Encoding 编码）\ u000d \ u000a

...

这是我的WCF功能：

    [DataContract]
    public class MailHeader
    {
        [DataMember] public Int64 EMailID;
        [DataMember] public MailAddress From;
        [DataMember] public MailAddress To;
        [DataMember] public DateTime TimeRecieved;
    }

    [DataContract]
    public class MailAddress
    {
        [DataMember] public Int64 AddressType;
        [DataMember] public Int64 AliasType;
        [DataMember] public string Name;
        [DataMember] public Int64 StudentID;
        [DataMember] public string SymbolURL;
        [DataMember] public string Address;
    }

    [DataContract]
    public class MailMessage
    {
        [DataMember] public MailHeader Header;
        [DataMember] public Int64 version;
        [DataMember] public XElement MailMessageXML;
        [DataMember] public byte[] CompressedBody;
    }

SendMessageStatusType SendMessage(Int64 StudentID, MailMessage Message,string ImageFileName);

This is my servicemodel from web.config:   
<system.serviceModel/>
    <behaviors>
      <endpointBehaviors>
        <behavior name="AjaxBehavior">
          <enableWebScript />
        </behavior>
      </endpointBehaviors>

      <serviceBehaviors>
        <behavior name="metadataGetBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" ></serviceDebug>
        </behavior>
      </serviceBehaviors>
    </behaviors>

    <bindings>
      <customBinding>
        <binding name="binaryEncoding" >
          <httpTransport />
        </binding>
      </customBinding>
    </bindings>

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
      multipleSiteBindingsEnabled="true" />


    <services>
      <service name="XXXX.Web.XXXXSVC" behaviorConfiguration="metadataGetBehavior">
        <endpoint address="ajax" behaviorConfiguration="AjaxBehavior"
            binding="webHttpBinding" contract="XXXX.Web.IXXXXSVC" />
        <endpoint address="binary"
          binding="customBinding" bindingConfiguration="binaryEncoding"
          contract="XXXX.Web.IXXXXSVC" />
      </service>
    </services>

  </system.serviceModel>

jquery调用很简单，与其他适用于我的调用相同：

$.ajax({

    type: "POST", 
    url: Url, // Location of the service
    data: Data, //Data sent to server
    contentType: "application/json; charset=utf-8",
    processdata: false, //True or False
    success: function (msg) {

        //On Successfull service call

        successCallBackFunc(msg);

    },

    error: errorCallBackFunc  // When Service call fails

});

为什么它不起作用的任何想法？

Answer 1

确定。我弄清楚了：

当你发送一个类型为XElement的字段时，它不能是一个空字符串，它必须是正确的XML格式。

同样适用于类型byte []，它必须在列表中：[0]

获取＆＃34;文件结束＆＃34;将复杂类型传递给WCF服务时
