通過.Net使用SAP Web服務

我對Web服務很陌生，所以我正在與一些奇怪的行爲作鬥爭。在通過VS2010導入WSDL xml文件後，我得到了這些無法識別的策略斷言。 WSDL文件是由SAP團隊創建的，所以我不確定他們到底做了什麼。通過.Net使用SAP Web服務

當我忽略這些評論嘗試使用web服務時，我得到這個期待： 提供的URI方案'https'是無效的;預計'http'。

我知道這個錯誤消息意味着我有一個不同的傳輸邏輯作爲URI定義，但我不知道如果我應該做些什麼或更新WSDL文件。

還是沒有解決方案？ – apacay 2014-07-03 21:19:19

您是否找到了解決方案？ – Carlos 2015-01-02 19:08:48

您的端點有http方案，但結合只定義httpsTransport。您可以嘗試將綁定更改爲httpTransport，或者查看您的端點是否也可用於https協議。

謝謝。我已將其更改爲** httpTransport **並切換到** authenticationScheme =「Basic」**，但現在我得到：** {「服務器沒有提供有意義的答覆;這可能是由於合同不匹配，會話過早關閉或內部服務器錯誤。「} ** – Marcin 2013-04-09 07:44:43

請嘗試使用TransportCredentialOnly作爲安全模式，不需要使用HTTPS協議（而您需要提供用戶名和密碼）。

<bindings> 
    <basicHttpBinding> 
    <binding name="NewBinding"> 
     <security mode="TransportCredentialOnly"> 
     <transport clientCredentialType="Basic" /> 
     </security> 
    </binding> 
    </basicHttpBinding> 
</bindings>

您可以在下面的.NET代碼的用戶名和密碼：

sapService.ClientCredentials.UserName.UserName = "UserName"; 
sapService.ClientCredentials.UserName.Password = "Password";
