Question

我将实现一个在HoughLineTransformation lineTransform = new HoughLineTransformation( ); // apply Hough line transofrm lineTransform.ProcessImage( sourceImage ); Bitmap houghLineImage = lineTransform.ToBitmap( ); // get lines using relative intensity HoughLine[] lines = lineTransform.GetLinesByRelativeIntensity( 0.5 ); foreach ( HoughLine line in lines ) { // get line's radius and theta values int r = line.Radius; double t = line.Theta; // check if line is in lower part of the image if ( r < 0 ) { t += 180; r = -r; } // convert degrees to radians t = ( t / 180 ) * Math.PI; Console.WriteLine("{0},{1}",t,r) // get image centers (all coordinate are measured relative // to center) int w2 = image.Width /2; int h2 = image.Height / 2; double x0 = 0, x1 = 0, y0 = 0, y1 = 0; if ( line.Theta != 0 ) { // none-vertical line x0 = -w2; // most left point x1 = w2; // most right point // calculate corresponding y values y0 = ( -Math.Cos( t ) * x0 + r ) / Math.Sin( t ); y1 = ( -Math.Cos( t ) * x1 + r ) / Math.Sin( t ); } else { // vertical line x0 = line.Radius; x1 = line.Radius; y0 = h2; y1 = -h2; } // draw line on the image Drawing.Line( sourceData, new IntPoint( (int) x0 + w2, h2 - (int) y0 ), new IntPoint( (int) x1 + w2, h2 - (int) y1 ), Color.Red );下工作的Web服务，以支持双工连接。但问题是我不知道如何保护它。我尝试使用NetHttpBinding，这是我的CostumUserNamePasswordValidationMode：

web.config

我认为问题是<behaviors> <serviceBehaviors> <behavior name="Behavior1"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true"/> <serviceCredentials> <serviceCertificate findValue="MyWebSite" storeLocation="LocalMachine" storeName="My" x509FindType="FindBySubjectName" /> <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="WcfWSChat.UserNamePassValidator, WcfWSChat" /> </serviceCredentials> </behavior> </serviceBehaviors> </behaviors> <bindings> <netHttpBinding> <binding name="Binding1"> <security mode="Message"> <message clientCredentialType="UserName"/> </security> </binding> </netHttpBinding> </bindings> <protocolMapping> <add scheme="http" binding="netHttpBinding"/> </protocolMapping> <services> <service name="WcfWSChat.WSChatService" behaviorConfiguration="Behavior1" > <endpoint address="" binding="netHttpBinding" bindingConfiguration="Binding1" contract="WcfWSChat.IWSChatService" /> <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" /> </service> </services>，每当我运行项目时，无论是在IIS Express还是IIS 8.0上，我都会收到此错误：

无法找到与绑定NetHttpBinding的端点匹配方案https的基址。注册的基地址方案是[http]。

如果我将<security mode="Message">属性更改为mode，我将不会再看到错误，但验证无效！

我该如何解决这个问题？

Answer 1

我认为你几乎接近解决方案。我试图复制你的问题，这就是我的意思。

在ServiceMetadata中添加并将httpsGetEnabled设置为true。 MetaData交换将在HTTPS中进行：

<serviceMetadata httpGetEnabled="True" httpsGetEnabled="True" />

将mexHttpBinding更改为mexHttpsBinding：

<endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"/>

在你的装订中添加：

<netHttpBinding>
   <binding name="netHttpBinding">
       <security mode="TransportWithMessageCredential">
           <message clientCredentialType="UserName"/>
       </security>
   </binding>
</netHttpBinding>

由于netHttpBinding默认使用http，我们需要一些映射。

<protocolMapping>
    <add scheme="https" binding="netHttpBinding"/>
</protocolMapping>

出于某种原因，即使我将protocolMapping更改为使用HTTPS进行netHttpBinding，我仍然会收到错误消息 “无法找到与绑定NetHttpBinding的端点的方案https匹配的基址。注册的基址方案是[http]。“ 。

所以我做的是，我在我的服务中添加了基于这样的地址：

<host>
    <baseAddresses>
       <add baseAddress="https://localhost/Services/"/>
    </baseAddresses>
</host>

如果您没有看到上面突出显示的任何错误消息，则可以转义第5步。我把它放在这里以防万一。

注意：我将证书安装在Personal下的证书存储区和受信任的根证书中的CA中。此示例仅在同一台计算机上运行，因为我的证书名称只是localhost。顺便说一下，我在这里使用.Net framework 4.5。

以下是我的完整配置：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="WcfServiceLibrary1.Service1" behaviorConfiguration="ServiceBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="https://localhost/Services/"/>
          </baseAddresses>
        </host>
        <endpoint address="" binding="netHttpBinding"  bindingConfiguration="netHttpBinding" contract="WcfServiceLibrary1.IService1" name="WcfServiceLibrary1.IService1"/>
        <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" listenUriMode="Explicit" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors >
        <behavior name="ServiceBehavior">
          <serviceCredentials>
            <serviceCertificate findValue="localhost" storeLocation="LocalMachine" storeName="My" x509FindType="FindBySubjectName" />
            **<!-- Retain your custom username password validator here -->**
          </serviceCredentials>
          <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True" />
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <netHttpBinding>
        <binding name="netHttpBinding">
          <security mode="TransportWithMessageCredential">
            <message clientCredentialType="UserName"/>
          </security>
        </binding>
      </netHttpBinding>
    </bindings>
    <protocolMapping>
      <add scheme="https" binding="netHttpBinding"/>
    </protocolMapping>
  </system.serviceModel>
</configuration>

Answer 2

似乎它可能与您注册为服务凭证的证书有关。

我尝试从serviceCertificate删除serviceBehaviours。

如果您想通过该证书强制执行SSL，那么我会将绑定部分中的安全模式更新为TransportWithMessageCredential，并将协议映射方案更改为https。
