'https' 无效；预期的“http”

Question

我一直在尝试向https://americas-uapi.copy-webservices.travelport.com/B2BGateway/connect/uAPI/SystemService 发送 ping 请求，但我收到以下错误： Error making ping request: The provided URI scheme 'https' is invalid; expected 'http'.

提供给我的端点使用 https。我该如何纠正这个错误？

这是我的 web.config

<?xml version="1.0"?>
 <configuration>
<system.web>
  <compilation debug="true" targetFramework="4.5" />
  <httpRuntime targetFramework="4.5" />
</system.web>

            <binding name="SystemPingBinding" />
            <binding name="SystemInfoBinding" />

</system.serviceModel>

这是我按照教程发送的请求：

// PING REQUEST
    //

    String payload= "this my payload; there are many like it but this one is mine";
    String someTraceId = "doesntmatter-8176";

    //set up the request parameters into a PingReq object
    PingReq req = new PingReq();
    PingRsp rsp = new PingRsp();
    req.Payload=payload;
    req.TraceId=someTraceId;
    SystemPingPortTypeClient port = new SystemPingPortTypeClient();
    try {
        //run the ping request
        UserNamePasswordClientCredential creds = port.ClientCredentials.UserName;
        creds.UserName = "MyUserName";
        creds.Password = "MyPassword";

        rsp = port.service(req);
        //print results.. payload and trace ID are echoed back in response
        Label1.Text = rsp.Payload;
        Label2.Text = rsp.TraceId;
        Label3.Text = rsp.TransactionId;
        } 
    catch (Exception ex) {
    //usually only the error message is useful, not the full stack
    //trace, since the stack trace in is your address space...
    Label1.Text = "Error making ping request: " + ex.Message;
