wcf - WCF WebSocket 服务需要安全 TLS/SSL WSS
问题描述
我们有一个用于 WebSockets 的现有 WCF Web 服务。我们将我们的解决方案分发给在 IIS 中托管应用程序的客户。我的任务是让服务使用端口 443 (WSS/HTTPS)。我已尝试更新 customBinding 的 Web.Config 以使用 httpsTransport,但我无法使用 wss:// 成功连接到服务。我已将我们应用程序的简化示例上传到使用 ws://的https://github.com/kevmoens/WcfWebSocketService 。
这是更新的 Web.Config 以尝试使用 httpsTransport
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.6.2" />
<httpRuntime targetFramework="4.6.2"/>
</system.web>
<system.serviceModel>
<services>
<service name="WcfWebSocketService.ConnectService"
behaviorConfiguration="WcfWebSocketService.ConnectService">
<endpoint address=""
binding="customBinding"
bindingConfiguration="webSocket"
contract="WcfWebSocketService.IConnectService"/>
</service>
</services>
<bindings>
<customBinding>
<binding name="webSocket">
<byteStreamMessageEncoding />
<httpsTransport>
<webSocketSettings transportUsage="Always"
createNotificationOnConnection="true"
/>
</httpsTransport>
</binding>
</customBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="WcfWebSocketService.ConnectService">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
如果我将其更改为使用 WS://,这是一个示例客户端。

// Log messages from the server
CONNECTION.onmessage = function (e) {

// when we press the Send button, send the text to the server
$('form').submit(function(){
CONNECTION.send($('#txtBox').val());
$('#txtBox').val('');
return false;
});
</script>
</body>
</html>
解决方案
我发现客户端在使用 IIS 并需要 SSL 时无法使用 localhost。我假设 httpTransport 需要更改为 httpsTransport 是正确的。此外,我不需要在 Web.Config 中添加任何关于证书的内容,因为它从 IIS 继承了证书。
客户
前
CONNECTION = new WebSocket('wss://localhost/ConnectService.svc');
后
CONNECTION = new WebSocket('wss://<MACHINENAME>/ConnectService.svc');
网页配置
前
<httpTransport>
<webSocketSettings transportUsage="Always"
createNotificationOnConnection="true"
/>
</httpTransport>
后
<httpsTransport>
<webSocketSettings transportUsage="Always"
createNotificationOnConnection="true"
/>
</httpsTransport>
