Question

嗨，我想知道是否有人可以帮助我，我一直在试图解决这个问题，但我还没有运气:(我在内部网络上的远程服务器上的IIS6上托管了一个WCF，{{ 3}}。我可以在浏览器中访问该服务，但是当尝试使用WcfTestClient发送请求时，我收到以下错误：

我已经尝试将我的web.config更改为这么多不同的值，这是不真实的，但是没有！任何想法都会非常受欢迎!!!

这是我的web.config

<?xml version="1.0"?>
<configuration>
    <configSections>
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >

Answer 1

由于您无法连接，因此可能是访问限制，但此消息可能会在您因其他问题被踢回时显示，因此这可能是缺少引用的二进制文件，或使用无效的{{1或类似的东西。

首先，打开一些诊断程序：

DataContract

现在运行该服务，获取错误并使用SvcTraceTool（只需转到<system.diagnostics> <sources> <source name="System.ServiceModel" switchValue="Warning, ActivityTracing" propagateActivity="true"> <listeners> <add type="System.Diagnostics.DefaultTraceListener" name="Default"> <filter type="" /> </add> <add name="ServiceModelTraceListener"> <filter type="" /> </add> </listeners> </source> </sources> <sharedListeners> <add initializeData="path\to\trace.svclog" type="System.Diagnostics.XmlWriterTraceListener, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="ServiceModelTraceListener" traceOutputOptions="Timestamp"> <filter type="" /> </add> </sharedListeners>并搜索Program Files\Microsoft SDKs）打开输出日志。这将为您提供有关该过程的更多概述，此时它会出错并指向异常的更多详细信息 - 有时只是告诉您查看事件日志中的特定异常。

Answer 2

无法连接到远程服务器无法建立连接因为目标机器主动拒绝它172.16.25.221:80

我会说这是防火墙问题，而不是web.config问题。你能在端口80上telnet到那个地址并得到回复吗？
