{

[服务合同]
公共接口IHelloWorld
{
[经营合同]
字符串GetData();
[经营合同]
列出GetPublisherList();
}
}
这是我对svc的标记:
<%@ ServiceHost Language="C#" Debug="true" Service="WCFRestExample.HelloWorld"
Factory="System.ServiceModel.Activation.WebServiceHostFactory"
CodeBehind="HelloWorld.svc.cs" %>
如果我从web.config中删除此部分,它可以正常工作:
<service name="WCFRestExample.HelloWorld">
<host>
<baseAddresses>
<add baseAddress="http://localhost:60503"/>
</baseAddresses>
</host>
<endpoint address="" binding="basicHttpBinding" contract="WCFRestExample.IHelloWorld"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
但是返回列表的方法仍然不起作用。我使用的是EF4.1。有人能告诉我发生了什么事吗
提前感谢:)将绑定从
basicHttpBinding
更改为webHttpBinding
。如果您想使用REST,您需要使用webHttpBinding。谢谢,现在有一种方法GetData
可以工作。但是方法GetPublisherList
仍然不起作用。当我浏览时,我没有得到任何错误和结果。你能告诉我为什么会这样吗?@Bob:在FireBug或Fiddler中看到响应结果,让我知道Fiddler中没有响应。没有错误,没有响应。我认为REST与实体框架不兼容。如果我创建一些超级简单的自定义对象,其中包含诸如Name和RollNo之类的字符串,那么它就可以正常工作。更新:我收到以下错误EntityReference不能有多个相关对象,但查询返回了多个相关对象。这是一个不可恢复的错误。
我正在使用pubs数据库。使用wsHttpBinding
而不是basicHttpBinding
是否会更改anything@V4Vendetta:不需要webHttpBinding。
