The provided URI scheme 'https' is invalid; expected 'http'. Parameter name: via

I am trying to make a WCF service over basicHttpBinding to be used over https. Here's my web.config:

<!-- language: xml -->
<service behaviorConfiguration="MyServices.PingResultServiceBehavior"
         name="MyServices.PingResultService">
    <endpoint address="" 
              binding="basicHttpBinding" 
              bindingConfiguration="defaultBasicHttpBinding"
              contract="MyServices.IPingResultService">
        <identity>
            <dns value="localhost" />
        </identity>
    </endpoint>
    <endpoint address="mex" 
              binding="mexHttpBinding" 
              contract="IMetadataExchange" />
</service>
...

<bindings>
  <basicHttpBinding>
    <binding name="defaultBasicHttpBinding">
      <security mode="Transport">
        <transport clientCredentialType="None"/>
      </security>
    </binding>
  </basicHttpBinding>开发者_如何学Python;
</bindings>
...
<behaviors>
  <serviceBehaviors>
    <behavior name="MyServices.UpdateServiceBehavior">
      <serviceMetadata httpsGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

I am connecting using WCFStorm which is able to retrieve all the meta data properly, but when I call the actual method I get:

The provided URI scheme 'https' is invalid; expected 'http'. Parameter name: via

Try adding message credentials on your app.config like:

<bindings> 
<basicHttpBinding> 
<binding name="defaultBasicHttpBinding"> 
  <security mode="Transport"> 
    <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> 
    <message clientCredentialType="Certificate" algorithmSuite="Default" />
  </security> 
</binding> 
</basicHttpBinding> 
</bindings> 

Adding this as an answer, just since you can't do much fancy formatting in comments.
I had the same issue, except I was creating and binding my web service client entirely in code.
Reason is the DLL was being uploaded into a system, which prohibited the use of config files.

Here is the code as it needed to be updated to communicate over SSL...

Public Function GetWebserviceClient() As WebWorker.workerSoapClient
    Dim binding = New BasicHttpBinding()
    binding.Name = "WebWorkerSoap"
    binding.CloseTimeout = TimeSpan.FromMinutes(1)
    binding.OpenTimeout = TimeSpan.FromMinutes(1)
    binding.ReceiveTimeout = TimeSpan.FromMinutes(10)
    binding.SendTimeout = TimeSpan.FromMinutes(1)

    '// HERE'S THE IMPORTANT BIT FOR SSL
    binding.Security.Mode = BasicHttpSecurityMode.Transport

    Dim endpoint = New EndpointAddress("https://myurl/worker.asmx")

    Return New WebWorker.workerSoapClient(binding, endpoint)
End Function

Change from

<security mode="None">

to

<security mode="Transport">

in your web.config file. This change will allow you to use https instead of http

Are you running this on the Cassini (vs dev server) or on IIS with a cert installed? I have had issues in the past trying to hook up secure endpoints on the dev web server.

Here is the binding configuration that has worked for me in the past. Instead of basicHttpBinding, it uses wsHttpBinding. I don't know if that is a problem for you.

<!-- Binding settings for HTTPS endpoint -->
<binding name="WsSecured">
    <security mode="Transport">
        <transport clientCredentialType="None" />
        <message clientCredentialType="None"
            negotiateServiceCredential="false"
            establishSecurityContext="false" />
    </security>
</binding>

and the endpoint

<endpoint address="..." binding="wsHttpBinding"
    bindingConfiguration="WsSecured" contract="IYourContract" />

Also, make sure you change the client configuration to enable Transport security.

I had same exception in a custom binding scenario. Anybody using this approach, can check this too.

I was actually adding the service reference from a local WSDL file. It got added successfully and required custom binding was added to config file. However, the actual service was https; not http. So I changed the httpTransport elemet as httpsTransport. This fixed the problem

<system.serviceModel>
<bindings>

  <customBinding>
    <binding name="MyBindingConfig">

      <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
        messageVersion="Soap11" writeEncoding="utf-8">
        <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
          maxBytesPerRead="4096" maxNameTableCharCount="16384" />
      </textMessageEncoding>

      <!--Manually changed httpTransport to httpsTransport-->
      <httpsTransport manualAddressing="false" maxBufferPoolSize="524288"
        maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Anonymous"
        bypassProxyOnLocal="false" 
        decompressionEnabled="true" hostNameComparisonMode="StrongWildcard"
        keepAliveEnabled="true" maxBufferSize="65536" 
        proxyAuthenticationScheme="Anonymous"
        realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
        useDefaultWebProxy="true" />
    </binding>
  </customBinding>

</bindings>

<client>
  <endpoint address="https://mainservices-certint.mycompany.com/Services/HRTest"
    binding="customBinding" bindingConfiguration="MyBindingConfig"
    contract="HRTest.TestWebserviceManagerImpl" name="TestWebserviceManagerImpl" />
</client>


</system.serviceModel>

1. WCF with custombinding on both http and https

I had the EXACT same issue as the OP. My configuration and situation were identical. I finally narrowed it down to being an issue in WCFStorm after creating a service reference in a test project in Visual Studio and confirming that the service was working. In Storm you need to click on the "Config" settings option (NOT THE "Client Config"). After clicking on that, click on the "Security" tab on the dialog that pops up. Make sure "Authentication Type" is set to "None" (The default is "Windows Authentication"). Presto, it works! I always test out my methods in WCFStorm as I'm building them out, but have never tried using it to connect to one that has already been set up on SSL. Hope this helps someone!

Ran into the same issue, this is how my solution turned out at the end:

        <basicHttpsBinding>
            <binding name="VerificationServicesPasswordBinding">
              <security mode="Transport">
              </security>
            </binding>
            <binding name="VerificationServicesPasswordBinding1" />
        </basicHttpsBinding>

I basically replaced every occurrence of Http with Https. You can try adding both of them if you prefer.

If you do this programatically and not in web.config its:

new WebHttpBinding(WebHttpSecurityMode.Transport)

Its a good to remember that config files can be split across secondary files to make config changes easier on different servers (dev/demo/production etc), without having to recompile code/app etc. For example we use them to allow onsite engineers to make endpoint changes without actually touching the 'real' files.

First step is to move the bindings section out of the WPF App.Config into it's own separate file.

The behaviours section is set to allow both http and https (doesn't seem to have an affect on the app if both are allowed)

<serviceMetadata httpsGetEnabled="true" httpGetEnabled="true" />

And we move the bindings section out to its own file;

 <bindings configSource="Bindings.config" /> 

In the bindings.config file we switch the security based on protocol

  <!-- None = http:// -->
  <!-- Transport = https:// -->
  <security mode="None" >

Now the on site engineers only need to change the Bindings.Config file and the Client.Config where we store the actual URL for each endpoint.

This way we can change the endpoint from http to https and back again to test the app without having to change any code.

Hope this helps.

To re-cap the question in the OP:

I am connecting [to a WCF service] using WCFStorm which is able to retrieve all the meta data properly, but when I call the actual method I get:

The provided URI scheme 'https' is invalid; expected 'http'. Parameter name: via

The WCFStorm tutorials addresses this issue in Working with IIS and SSL.

Their solution worked for me:

1. To fix the error, generate a client config that matches the wcf service configuration. The easiest way to do this is with Visual Studio.

   • Open Visual Studio and add a service reference to the service. VS will generate an app.config file that matches the service

   • Edit the app.config file so that it can be read by WCFStorm. Please see Loading Client App.config files. Ensure that the endpoint/@name and endpoint/@contract attributes match the values in wcfstorm.

2. Load the modified app.config to WCFStorm [using the Client Config toobar button].

3. Invoke the method. This time the method invocation will no longer fail

Item (1) last bullet in effect means to remove the namespace prefix that VS prepends to the endpoint contract attribute, by default "ServiceReference1"

<endpoint ... contract="ServiceReference1.ListsService" ... />

so in the app.config that you load into WCFStorm you want for ListsService:

<endpoint ... contract="ListsService" ... />

I needed the following bindings to get mine to work:

        <binding name="SI_PurchaseRequisition_ISBindingSSL">
          <security mode="Transport">
            <transport clientCredentialType="Basic" proxyCredentialType="None" realm="" />
          </security>
        </binding>

wsHttpBinding is a problem because silverlight doesn't support it!

I've added a "Connected Service" to our project by Visual Studio which generated a default method to create Client.

var client = new MyWebService.Client(MyWebService.Client.EndpointConfiguration.MyPort, _endpointUrl);

This constructor inherits ClientBase and behind the scene is creating Binding by using its own method Client.GetBindingForEndpoint(endpointConfiguration):

public Client(EndpointConfiguration endpointConfiguration, string remoteAddress) :
            base(Client.GetBindingForEndpoint(endpointConfiguration), 
                 new System.ServiceModel.EndpointAddress(remoteAddress))

This method has different settings for https service and http service. When you want get data from http, you should use TransportCredentialOnly:

System.ServiceModel.BasicHttpBinding result = new System.ServiceModel.BasicHttpBinding();
result.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.TransportCredentialOnly;
 

For https you should use Transport:

result.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.Transport;

In my case in web.config I had to change binding="basicHttpsBinding" to binding="basicHttpBinding" in the endpoint definition and copy the relative bindingConfiguration to basicHttpBinding section

<!-- Binding settings for HTTPS endpoint -->
<binding name="yourServiceName">
    <security mode="Transport">
        <transport clientCredentialType="None" />
        <!-- Don't use message -->
    </security>
</binding>

My solution, having encountered the same error message, was even simpler than the ones above, I just updated the to basicHttpsBinding>

  <bindings>
    <basicHttpsBinding>
    <binding name="ShipServiceSoap" maxBufferPoolSize="512000" maxReceivedMessageSize="512000" />
    </basicHttpsBinding>
    </bindings>

And the same in the section below:

  <client>
    <endpoint address="https://s.asmx" binding="basicHttpsBinding" bindingConfiguration="ShipServiceSoap" contract="..ServiceSoap" name="ShipServiceSoap" />
    </client>

FWIW this error can happen if you are not carful when adding your service reference to the application that is calling the https service

For example if you deleted your previous service reference that used to be http://example.com/Service.svc and then recreated it so it is now https://example.com/service.svc.

If you are not careful to delete the old client and binding in the web.config before recreating the service reference it will create BasicHttpBinding_IService1 instead of BasicHttpBinding_IService. Then when you deploy the application to the actual server it will say 'https is invalid expected http' because its looking for BasicHttpBinding_IService1 & not BasicHttpBinding_IService any longer.

Meanwhile you are trying all the suggestions above with no result.

Just thought I would throw that out there.
