帶有大量消息的WCF呼叫服務

我正在調用WCF服務的一種方法。該方法將圖像內的圖形傳遞給服務。帶有大量消息的WCF呼叫服務

所有來電拋出異常的說法：

The remote server returned an unexpected response: (400) Bad Request

我已閱讀關於這個問題的帖子很多，他們大多建議提高maxReceivedMessageSize。我試圖修改這個和其他設置，但它不能解決問題。

最後我已經激活服務器跟蹤它說：

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

在我的配置文件中的值設置爲65536000.

我的配置文件：

我不知道如何解決你最後的問題智者。我們在公司使用不同的綁定，並在我們的'httpTransport'上設置'max ... Size'屬性。我已經刪除了我的答案，因此您的問題會得到更多的關注，因爲沒有答案。 – dasblinkenlight 2012-01-06 18:48:38

我認爲WCF不會因爲某種原因閱讀我的綁定配置，而是將默認的配置放置在它的位置。感謝您的嘗試。 – Jakub 2012-01-06 19:07:02

你可能需要在客戶端和服務上定義MaxReceivedMessageSize屬性。

我同意，我認爲客戶正在得到比預期更大的信息。 – 2012-01-09 13:30:28

客戶端上的MaxReceivedMessageSize設置無關緊要，圖像從客戶端傳遞到服務器而不是其他方式。據我所知，如果您從服務器獲得大量響應，您需要在客戶端上調整此屬性的大小。 – Jakub 2012-01-09 16:45:37

另外，爲了100％確定：客戶端上的設置是相同的，我沒有問題在客戶端上獲取完全相同的數據。 – Jakub 2012-01-09 16:54:03

增加消息的最大配額，可能超時也取決於消息的大小 - 你可以這樣聲明性地或以編程方式如下所示。

BasicHttpBinding Binding = new BasicHttpBinding（）;

Binding.ReceiveTimeout = new TimeSpan(???, 0, 0); 
Binding.SendTimeout = new TimeSpan(???, 0, 0); 
Binding.OpenTimeout = new TimeSpan(???, 0, 0); 
Binding.CloseTimeout = new TimeSpan(???, 0, 0); 

Binding.ReaderQuotas.MaxStringContentLength = ???; 
Binding.ReaderQuotas.MaxArrayLength = ???; 
Binding.ReaderQuotas.MaxBytesPerRead = ???; 
Binding.ReaderQuotas.MaxNameTableCharCount = ???; 
Binding.MaxReceivedMessageSize = ???; 
Binding.MaxBufferPoolSize = ???;

將您的有效載荷送入小塊

選項1：組塊的有效載荷自己

選項2：通道分塊 http://msdn.microsoft.com/en-us/library/aa717050(v=vs.110).aspx
