WCF REST服务不返回的浏览器数据 [英] WCF Rest Service Not returning data in browser
问题描述
我有一个返回一个简单的字符串REST服务。当我使用WCF测试客户端的服务返回预期值，但是当我使用浏览器访问该服务时，页面出现空。有任何想法吗？所有code是如下。
CUCC.svc.cs
公共类CUCC：ICUCC
{
公共字符串AllAtms（字符串的serviceKey）
{
//返回新的XElement（AllAtms）;
返回测试;
}
//公众的XElement AllOrganizationAtms（字符串的serviceKey，INT organizationId）
// {
//返回新的XElement（AllOrganizationAtms）;
//}
}
ICUCC.cs
[的ServiceContract]
公共接口ICUCC
{
[OperationContract的]
[WebInvoke（方法=GET，
ResponseFormat = WebMessageFormat.Xml，
BodyStyle = WebMessageBodyStyle.Wrapped，
UriTemplate =AllAtms / {的serviceKey}）]
字符串AllAtms（字符串的serviceKey）;
// [OperationContract的]
// [WebInvoke（方法=GET，
// ResponseFormat = WebMessageFormat.Xml，
// BodyStyle = WebMessageBodyStyle.Wrapped，
// UriTemplate =AllAtms / {的serviceKey} / {organizationId}）]
//的XElement AllOrganizationAtms（字符串的serviceKey，INT organizationId）;
}

对不起，忘了，包括我使用的URL。
的http：//本地主机：51870 / CUCC.svc / AllAtms /测试
该问题是在这里：
＆LT;服务名称=CUCC.AllAtmsbehaviorConfiguration =ServiceBehaviour＆GT;
＆LT;端点地址=绑定=的WebHttpBinding合同=CUCC.AllAtmsbehaviorConfiguration =网络＆GT;＆LT; /端点＆GT;
＆LT; /服务＆GT;
此服务定义声称，有一个名为AllAtms在CUCC命名空间服务;但不存在这样的服务。当你调用使用SVC文件的URI的服务，IIS试图找到匹配您正在使用的服务的实际名称的服务定义。 IIS获得正确的名称从SVC文件的服务，但它没有找到一个服务配置匹配正确的服务名称，所以它返回的HTTP 400（错误请求）。你可以看到轻松地使用招这样的结果。
该服务的名称应该是实现类的命名空间限定名称和合同应该是接口的命名空间限定名称。例如：
＆LT;服务名称=StackOverflow15910199.CUCC＆GT;
＆LT;端点地址=绑定=的WebHttpBinding合同=StackOverflow15910199.ICUCCbehaviorConfiguration =网/＆GT;
＆LT; /服务＆GT;
这必须是与该服务相关的WCF库项目有一个正确定义的服务和端点在App.config文件的情况下，这就是为什么WCF测试客户端的工作。测试客户端不应该和你一起工作已经张贴服务配置。
I have a REST service that returns a simple string. When I use WCF Test Client the service returns the expected value, but when I use a browser to access the service, the page comes up empty. Any ideas? All code is below.
CUCC.svc.cs
public class CUCC : ICUCC
{
public string AllAtms(string serviceKey)
{
//return new XElement("AllAtms") ;
return "test";
}
//public XElement AllOrganizationAtms(string serviceKey, int organizationId)
//{
// return new XElement("AllOrganizationAtms");
//}
}
ICUCC.cs
[ServiceContract]
public interface ICUCC
{
[OperationContract]
[WebInvoke(Method = "GET",
ResponseFormat = WebMessageFormat.Xml,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "AllAtms/{serviceKey}")]
string AllAtms(string serviceKey);
//[OperationContract]
//[WebInvoke(Method = "GET",
// ResponseFormat = WebMessageFormat.Xml,
// BodyStyle = WebMessageBodyStyle.Wrapped,
// UriTemplate = "AllAtms/{serviceKey}/{organizationId}")]
//XElement AllOrganizationAtms(string serviceKey, int organizationId);
}

UPDATE
Sorry, forgot to include the url that I am using.
http://localhost:51870/CUCC.svc/AllAtms/testing
The problem is here:
<service name="CUCC.AllAtms" behaviorConfiguration="ServiceBehaviour">
<endpoint address="" binding="webHttpBinding" contract="CUCC.AllAtms" behaviorConfiguration="web"></endpoint>
</service>
This service definition claims that there is a service named AllAtms in the CUCC namespace; but there is no such service. When you invoke the service using the URI of your svc file, IIS attempts to find a service definition that matches the actual name of the service you are using. IIS gets the correct name for the service from the svc file but it doesn't find a service configuration matching the correct service name, so it returns HTTP 400 (Bad Request). You can see this result easily using Fiddler.
The service name should be the namespace qualified name of the implementation class and the contract should be the namespace qualified name of the interface. For example:
<service name="StackOverflow15910199.CUCC">
<endpoint address="" binding="webHttpBinding" contract="StackOverflow15910199.ICUCC" behaviorConfiguration="web" />
</service>
It must be the case that the WCF library project associated with this service has a properly defined service and endpoint in its App.config file, that's why the WCF test client is working. The test client should not have worked with service configuration you've posted.
