WCF服务wsHttpBinding

Question

使用wsHtpBinding帮助页面创建wcf服务时出错，服务也不起作用

帮助页错误

找不到资源。描述: HTTP 404。您正在寻找的资源(或其依赖项之一)可能已被删除、名称更改或暂时不可用。请检查以下URL并确保其拼写正确。http://localhost:80/Service1.svc/help

我以前的工作wsHttpbinding项目web.config，但现在不起作用了：

web.config

<?xml version="1.0"?>
<configuration>
  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" executionTimeout="3600" maxRequestLength="10000000"/>
    <customErrors mode="Off" />
  </system.web>

        <behavior name="">

          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <wsHttpBinding >
        <binding name="MyBasicwsHttpBinding">
          <security mode="None">
            <transport clientCredentialType="None" />
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <services>
      <service behaviorConfiguration="MyServiceTypeBehaviors"  name="WcfService1.Service1">
        <endpoint address="mex"  binding="wsHttpBinding" bindingConfiguration="MyBasicwsHttpBinding" name="WcfService1.Service1" contract="WcfService1.IService1"/>
      </service>
    </services>
    <serviceHostingEnvironment minFreeMemoryPercentageToActivateService="0" aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <directoryBrowse enabled="true"/>
  </system.webServer>
</configuration>

在我的例子中，我发现在IIS /网站上安装了一个Microsoft过滤模块Url扫描3.1，它有自己的限制，根据内容大小拒绝传入的请求并返回"404 Not页面“。

它的限制可以在%windir%\System32\inetsrv\urlscan\UrlScan.ini文件中通过将MaxAllowedContentLength设置为所需的值来更新。

就像。以下将允许最多300 mb的请求

MaxAllowedContentLength=314572800
