SOAP HTTP請求很慢

Question

對於SOAP HTTP請求，我完全陌生。有人能給我一個關於可能會減緩它的事情的廣泛破壞。我正在使用SOAP，WSDL的.NET應用程序。該請求每次大約需要50秒。我可能沒有任何意義，所以請原諒我的無知。在我的結尾處可以做些什麼，以便允許請求在不導致頁面不加載的情況下運行。 AJAX也許。

編輯（09/08/2009）：

OK，我用SOAPUI及其未來與兩個選項WebServiceSoap12和WebServiceSoap。第一個是goving我迅速毫秒的響應，第二個是給我一個「400錯誤的請求。爲什麼我需要的是第二個？

下面是WSDL

Answer 1

你應該首先嚐試以確定延遲的原因，因爲可能有很多原因，您的主要興趣是如果延遲發生在服務器側或（您的）客戶端上

如果延遲是在服務器端的東西（可能是一個複雜的操作來創建一個結果，可能是緩慢的服務器等），那麼你可以尋找解決方法來處理你的c lient，如：

• 創建頁面第一，通過AJAX之後從服務拉出數據，如你所說
• 在定期服務的前期拉動的數據並將其存儲在本地緩存從您建造網頁
• 等...

如果延遲在客戶端上發生的事情，你應該嘗試找到根本原因（如網絡配置，超時與反向查找等），並解決它;）

編輯：鑑於貼WSDL，Web服務提供了自己在兩個變化，一個是「默認」 SOAP和一個用於SOAP 1.2。 400響應表明客戶端以非標準符合方式發出請求，但也可能是服務端沒有正確設置它在wsdl中提供的協議版本。

至於爲什麼你需要一個或另一個，答案很簡單：兩者都提供完全相同的方法，所以你只需要一個。它可能是可能是是延遲是由您的客戶端首次試圖使用已停用的版本幾次，並在一段時間後只切換到另一個 - 但這只是猜測。如果SOAPUI適用於1.2版本，我只是試圖告訴客戶端使用它，並看看是否能加快速度。
