我正在尝试为我的RESTful Web服务创建一个c＃客户端应用程序。
我已将Web引用（ServiceReference1）添加到客户端应用程序，但我收到的错误如“UserService1.svc”不存在端点配置。
我知道'添加服务引用'在使用Rest服务时没有创建所有必需的配置，但我真的看不到我出错的地方！
这是我的文件
客户端申请
namespace WebServiceClient
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
UserService1Client webService;
List<User> userList = new List<User>();
public MainWindow()
{
InitializeComponent();
webService = new UserService1Client();
serviceMethods();
}
private void serviceMethods()
{
string[] results = webService.GetUsersNames();
}
}
}
客户 - web.config

希望有人能帮帮我!!
答案 0 :(得分：1)
首先，对于RESTFUL服务，您需要声明webhttpbinding，而不是basichttpbinding（这是针对SOAP服务的）。在您的REST服务中，您应该具有这些配置
1）声明您的服务及其端点
<services>
<service name="SparqlService.SparqlService" behaviorConfiguration="ServiceBehavior">
<endpoint binding="webHttpBinding" contract="SparqlService.ISparqlService" behaviorConfiguration="webHttp" />
</service>
</services>
服务名称将是[项目名称]。[服务名称]行为配置将与您在下一步中声明的行为相同。绑定必须是webHttpBinding，因为您希望将其作为REST。如果需要SOAP，则声明为basicHttpBinding Contract是[项目名称]。[接口名称]端点中的行为配置将是您在下一步中声明的名称
2）声明服务行为（通常是默认值）
<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
行为名称可以是任何内容，但它将用于匹配您在步骤1中声明的BehaviorConfiguration，其余部分单独使用
3）Delcare您的终端行为
<endpointBehaviors>
<behavior name="webHttp">
<webHttp />
</behavior>
</endpointBehaviors>
Beavior名称可以是任何名称，但它将用于匹配端点中的behaviorConfiguration。
最后，这就是web.config对于简单的REST服务应该是什么样子：
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<services>
<service name="SparqlService.SparqlService" behaviorConfiguration="ServiceBehavior">
<endpoint binding="webHttpBinding" contract="SparqlService.ISparqlService" behaviorConfiguration="webHttp" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
<behavior>
<!-- 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>
<endpointBehaviors>
<behavior name="webHttp">
<webHttp />
</behavior>
</endpointBehaviors>
</behaviors>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
</system.webServer>
</configuration>
完成web.config后，这是一个示例WCF REST服务及其各自的C＃客户端
要通过POST或PUT发送数据，您需要根据WCF服务正确构建数据。这基本上就是你需要的（只需将POST更改为你的应用程序的PUT）
1）WCF服务接口
[OperationContract]
[WebInvoke(Method = "POST",
UriTemplate = "GetData",
RequestFormat = WebMessageFormat.Xml,
BodyStyle = WebMessageBodyStyle.Bare)]
string GetData(DataRequest parameter);
2）WCF服务实施
public string GetData(DataRequest parameter)
{
//Do stuff
return "your data here";
}
3）WCF服务中的数据合同（在本例中为DataRequest）
[DataContract(Namespace = "YourNamespaceHere")]
public class DataRequest
{
[DataMember]
public string ID{ get; set; }
[DataMember]
public string Data{ get; set; }
}
4）发送数据的客户必须正确构建数据！ （在这种情况下是C＃console app）
static void Main(string[] args)
{
ASCIIEncoding encoding = new ASCIIEncoding();
string SampleXml = "<DataRequest xmlns=\"YourNamespaceHere\">" +
"<ID>" +
yourIDVariable +
"</ID>" +
"<Data>" +
yourDataVariable +
"</Data>" +
"</DataRequest>";
string postData = SampleXml.ToString();
byte[] data = encoding.GetBytes(postData);
string url = "http://localhost:62810/MyService.svc/GetData";
string strResult = string.Empty;
// declare httpwebrequet wrt url defined above
HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create(url);
// set method as post
webrequest.Method = "POST";
// set content type
webrequest.ContentType = "application/xml";
// set content length
webrequest.ContentLength = data.Length;
// get stream data out of webrequest object
Stream newStream = webrequest.GetRequestStream();
newStream.Write(data, 0, data.Length);
newStream.Close();
//Gets the response
WebResponse response = webrequest.GetResponse();
//Writes the Response
Stream responseStream = response.GetResponseStream();
StreamReader sr = new StreamReader(responseStream);
string s = sr.ReadToEnd();
return s;
}
