通过.Net使用SAP Web服务

我对Web服务很陌生，所以我正在与一些奇怪的行为作斗争。在通过VS2010导入WSDL xml文件后，我得到了这些无法识别的策略断言。 WSDL文件是由SAP团队创建的，所以我不确定他们到底做了什么。通过.Net使用SAP Web服务

当我忽略这些评论尝试使用web服务时，我得到这个期待： 提供的URI方案'https'是无效的;预计'http'。

我知道这个错误消息意味着我有一个不同的传输逻辑作为URI定义，但我不知道如果我应该做些什么或更新WSDL文件。

还是没有解决方案？ – apacay 2014-07-03 21:19:19

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

您的端点有http方案，但结合只定义httpsTransport。您可以尝试将绑定更改为httpTransport，或者查看您的端点是否也可用于https协议。

谢谢。我已将其更改为** httpTransport **并切换到** authenticationScheme =“Basic”**，但现在我得到：** {“服务器没有提供有意义的答复;这可能是由于合同不匹配，会话过早关闭或内部服务器错误。“} ** – Marcin 2013-04-09 07:44:43

请尝试使用TransportCredentialOnly作为安全模式，不需要使用HTTPS协议（而您需要提供用户名和密码）。

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

您可以在下面的.NET代码的用户名和密码：

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