【问题描述】:
我使用 basicHttpBinding 开发了一个自托管的 WCF 服务,当客户端在本地计算机上时一切正常。但是当我尝试从网络上的任何机器连接时,它只是超时,给我以下错误:
There was an error downloading 'http://192.168.0.59:8888/DannyService?wsdl'.
Unable to connect to the remote server
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.168.0.59:8888
Metadata contains a reference that cannot be resolved: 'http://192.168.0.59:8888/DannyService?wsdl'.
Could not connect to http://192.168.0.59:8888/DannyService?wsdl. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.168.0.59:8888.
Unable to connect to the remote server
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.168.0.59:8888
If the service is defined in the current solution, try building the solution and adding the service reference again.
我假设我遗漏了一些基本的(无疑是显而易见的)问题,我会非常感谢您指出它。
以下是一个示例程序 + app.config,它说明了我在真实系统中遇到的相同行为,即它在本地运行良好,但是当我尝试连接时(连接到 http://192.168.0.59:8888/DannyService?wsdl 或 http://192.168.0.59:8888/DannyService ) 来自任何其他机器,它会超时。
namespace DannyService
{
using System;
using System.Reflection;
using System.ServiceModel;
[ServiceContract]
interface IDannyControl
{
[OperationContract]
string SayHi();
}
class DannyControl
: IDannyControl
{
public string SayHi()
{
return "Hi!";
}
}
class Program
{
static void Main(string[] args)
{
ServiceHost host = new ServiceHost(typeof(DannyControl));
host.Open();
Console.ReadLine();
host.Close();
}
}
}
和
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="DannyServiceBehaviour">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="DannyService.DannyControl" behaviorConfiguration="DannyServiceBehaviour">
<host>
<baseAddresses>
<add baseAddress="http://192.168.0.59:8888/DannyService"/>
</baseAddresses>
</host>
<endpoint address="danny" binding="basicHttpBinding" contract="DannyService.IDannyControl" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
</system.serviceModel>
</configuration>
非常感谢。
【问题讨论】:
-
你能从另一台机器上的浏览器中检索wsdl或查看svc文件吗?
-
如果您的意思是将192.168.0.59:8888/DannyService?wsdl 放在浏览器中,或者放在“添加服务引用”对话框中,那么不会。如果有什么,那我不知道。 ;-/
-
不。两者都只是超时。它是一个自托管服务(在 Windows 服务中)。但是我发布的示例具有完全相同的行为。试试看! ;-/
-
一切似乎都很好 - 真是个愚蠢的问题:当您尝试连接到 Windows NT 服务时,它是否已启动并正在运行?由于它是自托管的,因此确保服务正在运行是您自己的责任......
-
?wsdl 不与 basicHttpBinding 一起使用。只是192.168.0.59:8888/DannyService - 你试过吗?
