無法添加服務。服務元數據可能無法訪問。確保你的服務正在運行並且暴露元數據

Question

我正在編寫WCF服務。我的代碼是

namespace RestService 
{ 
    public class user 
    { 
     public user(string i, string b, string l) 
     { 
      id = i; 
      badgeNumber = b; 
      login = l; 
     } 

     public string id { get; set; } 
     public string badgeNumber { get; set; } 
     public string login { get; set; } 
    } 

    public class RestServiceImpl : IRestServiceImpl 
    { 
     #region IRestServiceImpl Members 

     public string XMLData(string id) 
     { 
      return "You requested product " + id; 
     } 

     public user[] JSONData(string id) 
     { 
      OleDbConnection connection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\confiz\Desktop\att2000.mdb"); 
      connection.Open(); 
      OleDbCommand command = new OleDbCommand("SELECT count(*) FROM USERINFO", connection); 
      int users_count = (int)command.ExecuteScalar(); 

      command = new OleDbCommand("SELECT * FROM USERINFO", connection); 
      OleDbDataReader reader = command.ExecuteReader(); 
     // string jsonString = ""; 
      user[] users = new user[users_count]; 

      int i=0; 
      while (reader.Read()) 
      { 
       users[i].id = reader["USERID"].ToString(); 
       users[i].badgeNumber = reader["Badgenumber"].ToString(); 
       users[i].login = reader["SSN"].ToString(); 

      /* user = new user(reader["USERID"].ToString(), reader["Badgenumber"].ToString(), reader["SSN"].ToString()); 
       System.Web.Script.Serialization.JavaScriptSerializer jsSerializer; 
       jsSerializer = new System.Web.Script.Serialization.JavaScriptSerializer(); 
       System.Text.StringBuilder sbUser = new System.Text.StringBuilder(); 
       jsSerializer.Serialize(user, sbUser); 
       string json = sbUser.ToString(); 
       */ 
      //  jsonString = jsonString + json; 

       i++; 
      } 
      connection.Close(); 
      return users; 
     } 

     #endregion 
    } 
} 

我的web.config文件是這樣的

<?xml version="1.0"?> 
<configuration> 

    <system.web> 
    <compilation debug="true" targetFramework="4.0" /> 
    </system.web> 
    <system.serviceModel> 
    <services> 
     <service name="RestService.RestServiceImpl" behaviorConfiguration="ServiceBehaviour"> 
     <!-- Service Endpoints --> 
     <!-- Unless fully qualified, address is relative to base address supplied above --> 
     <endpoint address ="" binding="webHttpBinding" contract="RestService.IRestServiceImpl" behaviorConfiguration="web"> 
      <!-- 
       Upon deployment, the following identity element should be removed or replaced to reflect the 
       identity under which the deployed service runs. If removed, WCF will infer an appropriate identity 
       automatically. 
      --> 
     </endpoint> 
     </service> 
    </services> 

    <behaviors> 
     <serviceBehaviors> 
     <behavior name="ServiceBehaviour"> 
      <!-- 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="web"> 
      <webHttp/> 
     </behavior> 
     </endpointBehaviors> 
    </behaviors> 
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> 
    </system.serviceModel> 
    <system.webServer> 
    <modules runAllManagedModulesForAllRequests="true"/> 
    </system.webServer> 

</configuration> 

但是當我運行這段代碼我得到無法添加服務錯誤 。服務元數據可能無法訪問。確保您的服務正在運行並展示元數據。

錯誤詳細信息：錯誤：無法從RestServiceImpl.svc獲取元數據如果這是您有權訪問的Windows（R）Communication Foundation服務，請檢查是否已啓用元數據發佈到指定地址。

我想說這是因爲您沒有在web.config中爲您的端點地址。

<endpoint address ="" binding="webHttpBinding" 
      contract="RestService.IRestServiceImpl" behaviorConfiguration="web">
