我收到了传说中的Error: Cannot obtain Metadata from...
消息,特别是http://localhost:1640/Service1.svc
我已经搜索了stackoverflow和谷歌,到目前为止,它都没有帮助。我创造了一个新产品,使其愚蠢,它仍然无法正常工作。所以我在这里寻求帮助。
我正在尝试设置一个使用JSON的WCF服务,这意味着我需要在C#中使用webhttpbinding。当我使用WCF测试客户端时,我得到上述元数据错误。我正在使用Visual Studio Express 2010和目标框架。我已经在这两天了,无法理解为什么或者问题是什么。
我将不胜感激任何帮助。谢谢。
这是我的web.config文件:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<services>
<service name="WcfService4.Service1"
behaviorConfiguration="jsonRestDefault">
<endpoint

behaviorConfiguration="RESTFriendly"

这是IService1.cs文件:

using System.Collections.Generic;

using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace WcfService4
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
[ServiceContract]
public interface IService1
{
[OperationContract]
[WebInvoke(
Method = "GET",
UriTemplate = "players",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Bare)]
List<Person> GetPlayers();
}
// Use a data contract as illustrated in the sample below to add composite types to service operations.
[DataContract]
public class Person
{
[DataMember]
public string FirstName { get; set; }
[DataMember]
public string LastName { get; set; }
[DataMember]
public int Age { get; set; }
public Person(string firstName, string lastName, int age)
{
this.FirstName = firstName;
this.LastName = lastName;
this.Age = age;
}
}
}
这是Service1.svc.cs文件:
using System;

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
public class Service1 : IService1
{
public List<Person> GetPlayers()
{
List<Person> players = new List<Person>();
players.Add(new Person ( "Peyton", "Manning", 35 ) );
players.Add(new Person ( "Drew", "Brees", 31 ) );
players.Add(new Person ( "Brett", "Favre", 38 ) );
return players;
}
}

除了布鲁诺博洛尼亚的答案和链接外,WCF REST Service not visible in WCFTestClient的链接还提供了一些非常有用的信息。基本上,它不起作用的原因是WCFTestClient不是为web设计的(想想JSON)。它通过SOAP挂钩。如果我有一个依赖于JSON的服务,我无法通过WCFTestClient测试它。
我看到可以在WCFTestClient中修改客户端配置文件以启用Web绑定,但这可能是因为WADL的未来验证或者有人写了WADL服务扩展。不过,这只是我个人的鉴定。否则,似乎没有人可以使用WCFTestClient工具使用JSON测试WCF服务。
