The content type text/html; charset=UTF-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8)

I created WCF service and testing WCF client using stand alone application. I was able to view this service using Internet Explorer also able to view in Visual studi开发者_JAVA技巧o service references. Here is the error message.

"The content type text/html; charset=UTF-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8)."

Could you please advice what could be wrong?

Thank you.

Since the returned content type is text/html, I suspect your call result in a server-side error outside of WCF (you are receiving an HTML error page).

Try viewing the response with a web debugging proxy such as Fiddler.

(Edit based on comments) :

Based on your comments, I see that your WCF is hosted under Sharepoint 2010, in a form-authenticated site.

The error you are receiving is due to the fact that your your WCF client is NOT authenticated with sharepoint -- it does not have a valid authentication cookie. Sharepoint then return an HTTP Redirect to an html page (the login.aspx page); which is not expected by your WCF client.

To go further you will have to obtain an authentication cookie from Sharepoint (see Authentication Web Service) and pass it to your WCF client.

(Updated edit) :

Mistake: The site is using claim based authentication.

Although this is not necessarily due to cookies or form authentication, the explaination of the provided error message remain the same. An authentication problem cause a redirection to an HTML page, which is not handled by the WCF client.

This may be helpful, check the url rewrite rules in ISS 7. This issue will occur if is you didn't configure rule properly.

It sounds like your application is expecting XML but is receiving plain text. What type of object are you passing in?

text/html is SOAP 1.1 header and Content-Type: application/soap+xml is SOAP 1.2 Verify your bindings and return header. It should be same either 1.1 or 1.2

Add the following code to the web.config server project

<system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="basicHttpBinding_IService">
      <security mode="Transport">
        <transport clientCredentialType="None" proxyCredentialType="None"/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>

<services>
  <service name="Service">
    <endpoint address="" name="BasicHttpBinding_IService"
              binding="basicHttpBinding"
              bindingConfiguration="basicHttpBinding_IService"
              contract="IService" />
  </service>

then update client web service,After the update, the following changes are made web.config

<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_IService">
      <security mode="Transport" />
    </binding>
  </basicHttpBinding>
</bindings>


  <endpoint address="https://www.mywebsite.com/Service.svc"
    binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IService"
    contract="Service.IService" name="BasicHttpBinding_IService" />

I hope to be useful

i was getting this error in NavitaireProvider while calling BookingCommit service (WCF Service Reference)

so, when we get cached proxy object then it will also retrived old SigninToken which still may not be persisted so that not able to authenticate

so as a solution i called Logon Service when i get this exception to retrieve new Token
