使用Ajax将JSON发送到WCF3.5
我在将JSON传递给Weight方法时遇到问题。我一直在找HTTP/1.1 415 Cannot process the message because the content type 'application/x-www-form-urlencoded; charset=UTF-8' was not the expected type 'text/xml; charset=utf-8'.
我想我的合同或web.config都有问题。我所有的研究结果都是空的。我将使用jQuery的$.ajax从Web部件调用此服务。
接口：
namespace XXX.SharePoint.WebServices
{
[ServiceContract]
public interface ICalculators
{
[OperationContract]
[WebInvoke(Method = "POST",
BodyStyle = WebMessageBodyStyle.WrappedRequest,
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json
)]
Single Weight(Single Width, Single Diameter, Single Size, Single Factor);
}
}web.config：
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<services>
<service behaviorConfiguration="XXX.SharePoint.WebServices.CustomServiceBehaviour"
name="XXX.SharePoint.WebServices.Calculators">
<endpoint address=""
binding="basicHttpBinding"
contract="XXX.SharePoint.WebServices.ICalculators" >
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://moss2010/"></add>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="XXX.SharePoint.WebServices.CustomServiceBehaviour">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="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="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>一如既往，提前感谢！

以下是IIS中托管的WCF服务的完整工作示例：
[ServiceContract]
public interface ICalculators
{
[OperationContract]
[WebInvoke(Method = "POST",
BodyStyle = WebMessageBodyStyle.Wrapped,
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json
)]
float Weight(float width, float diameter, float size, float factor);
}
public class Calculators : ICalculators
{
public float Weight(float width, float diameter, float size, float factor)
{
return 10f;
}
}calculators.svc
<%@
ServiceHost
Language="C#"
Debug="true"
Service="XXX.SharePoint.WebServices.Calculators"
Factory="System.ServiceModel.Activation.WebServiceHostFactory"
CodeBehind="Calculators.svc.cs"
%>web.config:
<system.serviceModel>
<services>
<service
behaviorConfiguration="XXX.SharePoint.WebServices.CustomServiceBehaviour"
name="XXX.SharePoint.WebServices.Calculators">
<endpoint
address=""
binding="webHttpBinding"
contract="XXX.SharePoint.WebServices.ICalculators"
/>
<endpoint
address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange"
/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="XXX.SharePoint.WebServices.CustomServiceBehaviour">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel> 在同一个ASP.NET应用程序中使用jQuery消费：
$.ajax({
url: '/calculators.svc/Weight',
type: 'POST',
contentType: 'application/json',
data: JSON.stringify({ Width: 1.2, Diameter: 2.3, Size: 3.4, Factor: 4.5 }),
success: function (result) {
alert(result.WeightResult);
}
});注意在web.config中使用webHttpBinding而不是basicHttpBinding (SOAP)，以及.svc文件中使用的特殊WebServiceHostFactory。

您发送的请求使用forms/url编码的内容类型(当data成员的值是对象时，这是jQuery.ajax的默认类型)，这是data默认不支持的。您可以按照Darin Dimitrov的建议将其更改为发送JSON，将您的服务操作更改为接受Stream作为参数并自己解析输入，或者扩展WCF以支持表单/url编码的数据。我已经在另一个问题(在RESTful WCF web service POST problem上)中发布了一个示例，它完成了后者。
此外，来自http://wcf.codeplex.com的"jQuery支持“的预览中也有一些支持该内容类型的代码。
