WCF通信错误

Question

几天来，我们一直遇到一个WCF通信错误，我不知道是什么导致了这个错误。我最初认为这是一个SSL证书问题，但它不是。我还确保只要在web浏览器上输入URL就可以到达endpoint，并且可以查看。我还确保默认的请求大小不会导致这个问题。我确信这些请求小于默认的30MB。

还有什么东西可以防止这种堆栈跟踪错误？

客户端堆栈跟踪：

由于通信失败，WCFDirector获取失败。

因为表单没有正确加载，所以必须关闭它。---

服务器堆栈跟踪：

在System. ServiceModel. Channel. HttpChannelU的System. ServiceModel. Channels.请求（Message，TimeSpan超时）在System. ServiceModel. Channel. ServiceChannel. ServiceChannel. In的System. ServiceModel.

Answer 1

尝试关闭KeepAlive。类似于：

var client = new MyWcfClient();
var customBinding = new CustomBinding(client.Endpoint.Binding);
var transportElement = customBinding.Elements.Find<HttpTransportBindingElement>();

transportElement.KeepAliveEnabled = false;

client.Endpoint.Binding = customBinding;

Rest API 和 SOAP 的仅配置版本
