Question

我为插入，更新，删除和检索数据创建了一个WCF服务。在IService1.cs文件中，我有以下代码。我在哪里宣布五种方法。

public interface IService1
    {
        [OperationContract]
        [WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped, Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "getInfo")]
        CustomerData Get();

        [OperationContract]
        [WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped, Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "GetJson")]
        String GetJson();

        [OperationContract]
        [WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped, Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "Insert")]
        void Insert(string name, string country);

        [OperationContract]
        [WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped, Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "Update")]
        void Update(int customerId, string name, string country);

        [OperationContract]
        [WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped, Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "Delete")]
        void Delete(int customerId); 
}
[DataContract]
    public class CustomerData
    {
        public CustomerData()
        {
            this.CustomersTable = new DataTable("CustomersData");
        }

        [DataMember]
        public DataTable CustomersTable { get; set; }
    }

我刚刚创建了一个名为＆＃34; GetJson＆＃34;的方法。从数据库表中获取数据并将其转换为Json strig并返回它。

在Service1.svc.cs文件中，我有以下代码。

public class Service1 : IService1
    {
 public CustomerData Get()
        {
            String CS = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
            using (SqlConnection con = new SqlConnection(CS))
            {
                using (SqlCommand cmd = new SqlCommand("select * from tblCustomers", con))
                {
                    using (SqlDataAdapter da = new SqlDataAdapter(cmd))
                    {
                        cmd.Connection = con;
                        using (DataTable dt = new DataTable())
                        {
                            CustomerData customer = new CustomerData();
                            da.Fill(customer.CustomersTable);
                            return customer;
                        }
                    }
                }
            }
        }
        public String GetJson()
        {
            String CS = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
            using (SqlConnection con = new SqlConnection(CS))
            {
                using (SqlCommand cmd = new SqlCommand("select * from tblCustomers", con))
                {
                    using (SqlDataAdapter da = new SqlDataAdapter(cmd))
                    {
                        cmd.Connection = con;
                        using (DataTable dt = new DataTable())
                        {
                            CustomerData customer = new CustomerData();
                            da.Fill(customer.CustomersTable);
                            String JsonString = JsonConvert.SerializeObject(customer.CustomersTable);
                            return JsonString;
                        }
                    }
                }
            }
        }
        public void Insert(String name, String country)
        {
            String CS = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
            using (SqlConnection con = new SqlConnection(CS))
            {
                con.Open();
                SqlCommand cmd = new SqlCommand("Insert into tblCustomers(Name, Country) values(@name,@country)", con);
                cmd.Parameters.AddWithValue("@name", name);
                cmd.Parameters.AddWithValue("@country", country);
                cmd.ExecuteNonQuery();
            }
        }
        public void Update(int customerId, string name, string country)
        {
            string constr = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
            using (SqlConnection con = new SqlConnection(constr))
            {
                using (SqlCommand cmd = new SqlCommand("UPDATE tblCustomers SET Name = @Name, Country = @Country WHERE CustomerId = @CustomerId"))
                {
                    cmd.Parameters.AddWithValue("@CustomerId", customerId);
                    cmd.Parameters.AddWithValue("@Name", name);
                    cmd.Parameters.AddWithValue("@Country", country);
                    cmd.Connection = con;
                    con.Open();
                    cmd.ExecuteNonQuery();
                    con.Close();
                }
            }
        }

        public void Delete(int customerId)
        {
            string constr = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
            using (SqlConnection con = new SqlConnection(constr))
            {
                using (SqlCommand cmd = new SqlCommand("DELETE FROM tblCustomers WHERE CustomerId = @CustomerId"))
                {
                    cmd.Parameters.AddWithValue("@CustomerId", customerId);
                    cmd.Connection = con;
                    con.Open();
                    cmd.ExecuteNonQuery();
                    con.Close();
                }
            }
        }
}

在＆＃34; GetJson＆＃34;方法datatable转换为Json String。

String JsonString =   JsonConvert.SerializeObject（customer.CustomersTable）;

返回JsonString;

在代码

之后的Web.config文件中

<configuration>   <connectionStrings>
    <add name="DBCS" connectionString="data source=.\MSSQL; database=Customers; integrated security=SSPI"/>   </connectionStrings> <system.web>
    <compilation debug="true" targetFramework="4.0" />   </system.web>   <system.serviceModel>
    <services>
      <service name="WcfService2.Service1" behaviorConfiguration="WcfService2.Service1Behavior">
        <endpoint address="" binding="webHttpBinding" behaviorConfiguration="REST" contract="WcfService2.IService1"></endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="WcfService2.Service1Behavior">
          <!-- 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="REST">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />   </system.serviceModel>  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>   </system.webServer> </configuration>

此Web服务已在IIS 7.5上成功托管，但在我尝试运行时

http://localhost/WcfService2/Service1.svc/GetJson

显示错误＆＃34;未找到端点＆＃34;。我认为Web.config文件中存在问题

<system.serviceModel>
    <services>
      <service name="WcfService2.Service1" behaviorConfiguration="WcfService2.Service1Behavior">
        <endpoint address="" binding="webHttpBinding" behaviorConfiguration="REST" contract="WcfService2.IService1"></endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="WcfService2.Service1Behavior">
          <!-- 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="REST">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

Answer 1

您在behaviorConfiguration代码中有service个属性重复。

尝试删除behaviorConfiguration="WcfService2.Service1Behavior"。

在WCF中找不到终点
