我一直在fx3.5上使用WCF学习和构建JSONP Web服务。你可以阅读我在.NET ASMX - Returning Pure JSON?进行的一些试验。我终于得到了一个样本,但现在我正在把它拖到我的应用程序中。
服务的web.config:
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="JsonpServiceBehavior">
<webHttp />
</behavior>
</endpointBehaviors>
</behaviors>
<services>
<service name="RivWorks.Web.Service.CustomerService">
<endpoint address=""
binding="customBinding"
bindingConfiguration="jsonpBinding"
behaviorConfiguration="JsonpServiceBehavior"
contract="RivWorks.Web.Service.ICustomerService" />
</service>
<service name="RivWorks.Web.Service.NegotiateService">
<endpoint address=""
binding="customBinding"
bindingConfiguration="jsonpBinding"
behaviorConfiguration="JsonpServiceBehavior"
contract="RivWorks.Web.Service.INegotiateService" />
</service>
</services>
<bindings>
<customBinding>
<binding name="jsonpBinding" >
<jsonpMessageEncoding />
<httpTransport manualAddressing="true"/>
</binding>
</customBinding>
</bindings>
<extensions>
<bindingElementExtensions>
<add name="jsonpMessageEncoding"
type="RivWorks.Web.Service.JSONP.JsonpBindingExtension
, RivWorks.Web.Service
, Version=1.0.0.0
, Culture=neutral
, PublicKeyToken=null"/>
</bindingElementExtensions>
</extensions>
</system.serviceModel>
我收到以下错误,我已经尝试了一切我能想到的解决方法。在我的代码中发现了一些拼写错误(服务而不是服务)。我正在使用MSDN处的示例代码。这是错误:
Configuration Error Description:** An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: The type 'RivWorks.Web.Service.JSONP.JsonpBindingExtension

有没有人对我还能检查什么有任何想法?有一个名为RivWorks.Web.Service.dll的DLL,它正在构建并复制到网站的bin目录中。 Web.config服务正被复制到Web站点的Services目录中。我在网站的web.config中没有任何冲突。我检查了所有拼写问题。
答案 0 :(得分:15)
构建输出中的dll(RivWorks.Web.Service.dll)是什么?
接下来,尝试(对于“jsonpMessageEncoding”扩展名):
type="RivWorks.Web.Service.JSONP.JsonpBindingExtension, RivWorks.Web.Service, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"
请注意" , "
和回车符的不同间距。
之后,我会检查字符串的高音。编写一个控制台exe,它引用你需要的dll(RivWorks.Web.Service),并输出:
Console.WriteLine(
typeof(RivWorks.Web.Service.JSONP.JsonpBindingExtension)
.AssemblyQualifiedName);
这是xml中你想要的字符串,逐字。不要在此字符串中包含任何额外的空格。
