通过.net使用SAP web服务

我对web服务还很陌生，所以我正在与一些奇怪的行为作斗争。在通过VS2010导入WSDL xml文件之后，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

当我忽略这些命令并尝试使用web服务时，我得到以下期望： 提供的URI方案“https”无效；应为“http”。

我知道这个错误消息意味着我有一个与URI定义的不同的传输逻辑，但是我不确定我是否应该对此做些什么或者更新WSDL文件

您的端点具有

http

方案，但绑定仅定义

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以使用

https

协议。

请尝试使用

TransportCredentialOnly

作为安全模式，该模式不需要https协议（同时需要提供用户名和密码）

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回复；这可能是由于契约不匹配、会话过早关闭或内部服务器错误造成的。”}您找到了解决方案吗？
