Question

我对网络服务很陌生，所以我正在与一些奇怪的行为作斗争。在我通过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。

当我无视这些纪念时尝试使用网络服务我得到了这些代价： 提供的URI方案“https”无效;预期'http'。

我知道这个错误消息意味着我有一个与URI定义不同的传输逻辑，但我不确定我是应该对它做些什么还是更新WSDL文件。

Answer 1

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。

Answer 2

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

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

您可以在.NET代码中设置用户名和密码，如下所示：

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

通过.net使用SAP Web服务
