[英]WCF client hangs on call with lots of data
我在Azure VM上具有WCF服务,并且我的方法在服务器端需要花费大量时间(取决于我发送的数据大小)。
问题是有时调用此方法时我的客户端挂起。 我知道该方法已完成并到达最后一行,但是我的客户从未得到响应。 当我将大量数据传递给该方法时,就会发生这种情况,并且大约需要1个小时才能完成。 如果该方法在几分钟内完成,则客户端将成功获取响应。
这是我的web.config

和客户端配置:
binding.OpenTimeout = new TimeSpan(100, 0, 0);
binding.CloseTimeout = new TimeSpan(100, 0, 0);
binding.SendTimeout = new TimeSpan(100, 0, 0);
binding.ReceiveTimeout = new TimeSpan(100, 0, 0);
完全没有例外。 客户端根本无法从服务器获得响应。
这是我调用的方法:
public Domain.DocumentGenerationResponse GenerateDocument(Guid id, Domain.PrintOptions printOptions, Domain.Job job)
it returns only several short strings. job arguments contains 1000 documents (each document has an image 111Kb)
