问使用OAuth对客户端进行身份验证后，如何调用经过身份验证的ServiceStack服务？

EN

// Create the ServiceStack API client and the request DTO
var apiClient = new JsonServiceClient("http://api.mysite.com/");
var apiRequestDto = new Shortlists { Name = "dylan" };

// Wire up the ServiceStack client filter so that DotNetOpenAuth can 
// add the authorization header before the request is sent
// to the API server
apiClient.LocalHttpWebRequestFilter = request => {
    // This is the magic line that makes all the client-side magic work :)
    ClientBase.AuthorizeRequest(request, accessTokenTextBox.Text);
}

// Send the API request and dump the response to our output TextBox
var helloResponseDto = apiClient.Get(apiRequestDto);

Console.WriteLine(helloResponseDto.Result);

var client = new JsonServiceClient (baseUri);

client.LocalHttpWebRequestFilter += (request) => {
    // compute signature using request and a previously obtained
    //  access token 
    string authorization_header = CalculateSignature (request, access_token);

    request.Headers.Add ("Authorization", authorization_header);
};
var response = client.Get<MySecuredResponse> ("/my/service");
