如何使用BasicHttpBinding和BasicHttpSecurityMode.TransportWithCredential將soap頭部元素「mustunderstand = 0」設置爲soap請求：

Question

我正在使用.NET WCF客戶端和C＃來使用Java WebService。在向此Web服務發送請求時，封裝的WCF客戶端始終使用元素mustunderstand=1，即使使用定製的MessageInspector實現IClientMessageInspector更改方法IClientMessageInspector.BeforeSendRequest中的標題元素。我猜BasicHttpBinding與BasicHttpSecurityMode.TrasportWithCredentials，總是把這個元素放在請求的頭部，忽略這些手動添加的頭文件。

這個mustunderstand=1頭元素在服務器端觸發錯誤，這個服務器不在我們的控制之下。 Id喜歡避免這個標題元素響應錯誤將mustunderstand=1的值更改爲mustunderstand=0。

所以有一個技巧或技巧來改變這個mustunderstand頭參數的值？

要ilustrate查看由FIDDLER和MessageInspector跟蹤的REQUEST RAW，RESPONSE RAW。

Answer 1

好了...這將需要一些工作，得到正確的。我不知道您是否熟悉綁定中的通道堆棧，但基本上，消息將通過WCF中的various operations流動，每個消息都將以某種方式轉換消息。

This answer，並且使用自定義消息編碼器是您需要做的事情，因爲WCF在修改標頭以刪除標頭後正在應用「正確」標頭（因爲它看到了它，由於指定的綁定） mustUnderstand屬性。

這是一個相當複雜的領域，我不得不使用它來獲取由WCF生成的SOAP頭，以符合WSE 3.0用於創建的東西，並在Security頭中包含一個二進制令牌;但是有一些試驗和錯誤，這是一個非常強大的功能。
