[ServiceContract]
public interface IPeopleInfo
{
[OperationContract]
int GetAge(string name);
}
数据契约:
[DataContract]
public class People
{
public string Name;
public int Age;
}
服务实现:
public class PeopleInfo : IPeopleInfo
{ public int GetAge(string name)
{
List<People> peopleList = DataFactory.GetPeopleList();
return peopleList.Find(t =>t.Name==name).Age ;
}
}
辅助类:
public class DataFactory
{
public static List<People> GetPeopleList()
{
List<People> peopleList = new List<People>();
peopleList.AddRange(new People[] {
new People{Name="tjm",Age=},
new People{Name="lw",Age=},
new People{Name="tj",Age=},
});
return peopleList;
}
}
WCF部署IIS出现“由于扩展配置问题而无法提供您请求的页面。如果该页面是脚本,请添加处理程序。如果应下载文件,请添加 MIME 映射”的解决办法
管理员身份运行C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe -i
HTTP 错误 404.3 - Not Found,
使用管理员注册:C:\Windows\system32>"C:\Windows\Microsoft.NET\Framework\v4.0.30319\ServiceModelReg.exe" -r
Microsoft(R) WCF/WF 注册工具版本 4.5.0.0
版权所有(C) Microsoft Corporation。保留所有权利。
用于管理一台计算机上 WCF 和 WF 组件的安装和卸载的管理实用工具。
[错误]此 Windows 版本不支持此工具。管理员应改为使用“打开或关闭 Windows 功能”对话框或 dism 命令行工具来安装/卸载 Windows Communication Foundation 功能。
根据错误的提示,去控制面板->程序->启用或关闭Windows功能,如下图
把我画红线的框内的复选框全部勾选,点击确定,然后再在iis中再进行浏览就能够找到发布后的WCF服务了,原因应该是我没有安装WCF服务的组件而导致的吧。在浏览器中浏览服务如下。
在window功能中卸载iis和WCF服务,然后再重新安装配置。
首先建立一个Winform项目,界面如下。
注意:在部署之前需要把第一步中编写服务的dll引用进来。
ServiceHost host;
private void btnStart_Click(object sender, EventArgs e)
{
//使用代码绑定
Uri tcpa = new Uri("net.tcp://172.21.212.54:8090/peopleinfo");
host = new ServiceHost(typeof(FirstWCFService.PeopleInfo), tcpa);
ServiceMetadataBehavior mBehave = new ServiceMetadataBehavior();
NetTcpBinding tcpb = new NetTcpBinding();
host.Description.Behaviors.Add(mBehave);
host.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexTcpBinding(), "mex");
host.AddServiceEndpoint(typeof(FirstWCFService.IPeopleInfo), tcpb, tcpa); host.Open();
this.btnStart.Enabled = false;
this.label1.Text = "Service Running";
} private void btnStop_Click(object sender, EventArgs e)
{
if (host != null)
{
host.Close();
this.label1.Text = "Service Closed";
this.btnStart.Enabled = true;
}
}
2)使用配置文件
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
<service name="FirstWCFService.PeopleInfo">
<!--客户端用来解释服务,这个端点如果缺少服务会发布失败-->
<endpoint contract="IMetadataExchange"
binding="mexTcpBinding" address ="net.tcp://172.21.212.54:8090/peoleinfo/mex"></endpoint>
<!--提供服务的端点-->
<endpoint address="net.tcp://172.21.212.54:8090/peoleinfo" binding="netTcpBinding"
contract="FirstWCFService.IPeopleInfo"> </endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
虽然是用来配置文件,但是开启服务的代码还是需要写的。代码如下。
ServiceHost host;
private void btnStart_Click(object sender, EventArgs e)
{
host = new ServiceHost(typeof(FirstWCFService.PeopleInfo));
host.Open();
this.btnStart.Enabled = false;
this.label1.Text = "Service Running";
} private void btnStop_Click(object sender, EventArgs e)
{
if (host != null)
{
host.Close();
this.label1.Text = "Service Closed";
this.btnStart.Enabled = true;
}
}
运行程序,点击Start按钮,到此使用Winform作为宿主来发布WCF服务已经成功了。
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IPeopleInfo" />
</basicHttpBinding>
<netTcpBinding>
<binding name="NetTcpBinding_IPeopleInfo">
</binding>
</netTcpBinding>
</bindings>
<client>
<endpoint address="http://172.21.212.54/PeopleInfo.svc" binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_IPeopleInfo" contract="HttpService.IPeopleInfo"
name="BasicHttpBinding_IPeopleInfo" />
<endpoint address="net.tcp://172.21.212.54:8090/peoleinfo" binding="netTcpBinding"
bindingConfiguration="NetTcpBinding_IPeopleInfo" contract="TcpService.IPeopleInfo"
name="NetTcpBinding_IPeopleInfo" />
</client>
</system.serviceModel>
</configuration>
调用服务操作的代码非常简单,就类似于操作本地的类一样,代码如下:
private void bntGet_Click(object sender, EventArgs e)
{
string name = this.txtName.Text;
int age;
if (rdbHttp.Checked)
{
HttpService.PeopleInfoClient httpClient = new HttpService.PeopleInfoClient();
age = httpClient.GetAge(name);
}
else
{
TcpService.PeopleInfoClient tcpClient = new TcpService.PeopleInfoClient();
age = tcpClient.GetAge(name);
}
this.txtAge.Text = age.ToString();
}
到此,wcf的客户端编写完成,结果如下。
System.ServiceModel.Security.SecurityNegotiationException: 服务器已拒绝客户端凭据。 --->
System.Security.Authentication.InvalidCredentialException: 服务器已拒绝客户端凭据。 --->
System.ComponentModel.Win32Exception: 登录没有成功
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
<service name="FirstWCFService.PeopleInfo">
<!--客户端用来解释服务,这个端点如果缺少服务会发布失败-->
<endpoint contract="IMetadataExchange"
binding="mexTcpBinding" address ="net.tcp://172.21.212.54:8090/peoleinfo/mex"></endpoint>
<!--提供服务的端点-->
<endpoint address="net.tcp://172.21.212.54:8090/peoleinfo" binding="netTcpBinding"
contract="FirstWCFService.IPeopleInfo" bindingConfiguration="NoSecurity">
</endpoint>
</service>
</services>
<bindings>
<netTcpBinding>
<binding name="NoSecurity">
<security mode="None"/>
</binding>
</netTcpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
设置完成之后,重新开启服务。然后在客户端删除winform宿主发布的服务,并且再重新添加,以便在配置文件中重新生成访问tcp方式的服务端点的配置。更新后的配置文件如下,红色加粗部分为更新的。
