asp.net Base-64字符串中的字符無效

我有一個c＃移動網站，並且與一些移動客戶端有問題。我在下面發佈了一個跟蹤，但基本上電話的瀏覽器或手機連接到internet url的wap網關編碼視圖狀態隱藏輸入的形式。asp.net Base-64字符串中的字符無效

/wEPDwULLTExNTMyOTcwOTBkGAEFBlBtTGlzdA9nZA ==

變得

％2FwEPDwULLTExNTMyOTcwOTBkGAEFBlBtTGlzdA9nZA％3D％3D

所以視圖狀態失敗。

有沒有辦法重寫和urldecode視圖狀態信息之前進行？

您可以實現它處理這個自定義ViewStatePersister對象。你可能想從HiddenFieldPageStatePersister中得到它。看一看this article，它顯示瞭如何在ViewState之上實現壓縮，但與您需要執行的操作非常相似。

有參與hackiness一點點：你需要使用反射來設置StateFormatter基類，它是，相反的是在MSDN docs說，沒有標記爲虛擬的，這樣不反射無法覆蓋的領域。

使用下面的解決方案，並檢查它是否工作。這個對我有用。將此代碼添加到您的asp.net代碼中，導致此問題。下面的代碼是在vb.net

Protected Overrides Function LoadPageStateFromPersistenceMedium() As Object 
     Return Session("_ViewState") 
    End Function 
Protected Overrides Sub SavePageStateToPersistenceMedium(viewState As Object) 
     Session("_ViewState") = viewState 
    End Sub

您需要在編程語言的問題要求提供代碼，*不*的編程語言你的選擇。 – cybermonkey 2015-12-11 19:47:55
