I am using a third party service & hence has no access to change anything from service side. I WSDL which I added as connect service.
The problem is that I have enabled the raw request & I can see error details in trace or debug log. But When I try to fetch details using following code it always return empty Detail Object.
try {
// my code to call service
}
catch (System.ServiceModel.FaultException<Error[]> errors) {
var err = Newtonsoft.Json.JsonConvert.SerializeObject(errors.Detail)
Console.WriteLine(err);
}
Edit: looks to be a duplicate of
FaultException.Detail coming back empty
The problem was the visual studio didn't quite map out the ErrorDetail objects right. The ErrorDetail node is called "ErrorDetail", but the type generated for it is "ErrorDetailType." I edited the reference.cs class generated for each service I was using and added a TypeName:

I am using the Nuget package Microsoft.Azure.CognitiveServices.Vision.CustomVision.Prediction
I have created a Custom Vision application in the Custom Vision portal and obtained API keys and a project ID.
Whenever I try to make a request to the API, I always get the following exception thrown:
HttpOperationException: Operation returned an invalid status code
'NotFound'
Here is my code:
HttpClient httpClient = new HttpClient();
CustomVisionPredictionClient customVisionPredictionClient = new CustomVisionPredictionClient(httpClient, false)
{
ApiKey = PredictionKey,
Endpoint = PredictionEndpoint,
};
var result = customVisionPredictionClient.PredictImageAsync(CUSTOM_VISION_PROJECT_GUID, imageData);
I have tried several different endpoints:
https://southcentralus.api.cognitive.microsoft.com/customvision/v2.0/Prediction
https://southcentralus.api.cognitive.microsoft.com/customvision/Prediction/v1.0
https://southcentralus.api.cognitive.microsoft.com/customvision/v1.1/Prediction
though on the portal the listed one is the first of the list. I have also succesfuly exported my app on Azure, which gives me the second endpoint in the list but with no more success.
I have also set a default iteration as suggested in a similar issue that I found ( CustomVision: Operation returned an invalid status code: 'NotFound' ).
I have tried this sample https://github.com/Microsoft/Cognitive-CustomVision-Windows/tree/master/Samples/CustomVision.Sample which uses a deprecated windows client, to at least ensure my project information are correct and I was able to access the API.
Any insight would be appreciated
For the .NET client SDK, you need to specify the base endpoint URL without the version or the rest of the path. The version is automatically added by the client SDK. In other words, you'll want (assuming SouthCentralUS is your region):
PreditionEndpoint = "https://southcentralus.api.cognitive.microsoft.com";
CustomVisionPredictionClient customVisionPredictionClient = new CustomVisionPredictionClient()
{
ApiKey = PredictionKey,
Endpoint = PredictionEndpoint,
};
var result = customVisionPredictionClient.PredictImageAsync(CUSTOM_VISION_PROJECT_GUID, imageData);
As an aside, note that unless you want to fine-tune the behavior, you don't need to pass in an HttpClient object to CustomVisionPredictionClient constructor.
If you need more sample code, please take a look at the QuickStart.
How to use the Prediction API
If you have an image URL:
your endpoint would be something like this
https://southcentralus.api.cognitive.microsoft.com/customvision/v2.0/Prediction/{Project-GUID}/url?iterationId={Iteration-ID}
Set Prediction-Key Header to : predictionId
Set Content-Type Header to : application/json
Set Body to : {"Url": "https://example.com/image.png"}
Or If you have an image file:
Endpoint would be like
https://southcentralus.api.cognitive.microsoft.com/customvision/v2.0/Prediction/{ProjectGuid}/image?iterationId={Iteration-Id}
Set Prediction-Key Header to : Predcition-key
Set Content-Type Header to : application/octet-stream
Set Body to : <image file>
Remember, you can mark an iteration as Default so you can send data to it without specifying an iteration id. You can then change which iteration your app is pointing to without having to update your app.

I am using a WCF client proxy to call a web service. I am adding logging to each request using IClientMessageInspector. I want to get info out of the underlying HTTP message, and found out I can get it by the following:
public class WCFLoggingInspector : IClientMessageInspector
{
public object BeforeSendRequest(ref Message request, IClientChannel channel)
{
var httpRequest = (HttpRequestMessageProperty)request.Properties[HttpRequestMessageProperty.Name];
var method = httpRequest.Method;
return null;
}
}
While stepping through in the debugger, this works fine. However, running normally, I get an error from the Properties indexer: "A property with the name 'httpRequest' is not present"
Can anyone explain whats going on here, or an alternate way to get at the HttpRequest? (I'm also doing the same thing for AfterReceiveReply)
It seems that Visual Studio creates this when the debugger is attached.
if (!properties.ContainsKey(HttpRequestMessageProperty.Name))
properties.Add("httpRequest", new HttpRequestMessageProperty());
Source: Property httpRequest' not present
Using Visual Studio 2010, I'm calling SOAP webservices and keep getting the error "Error in deserializing body of reply message".
I call the WS method like this:
wsConfig.config_pttClient client = new wsConfig.config_pttClient();
wsConfig.getConfigInput gci = new wsConfig.getConfigInput();
wsConfig.getConfigOutput gco = new wsConfig.getConfigOutput();
gco = client.getConfig(gci); // the exception is thrown here
The method doesn't need input data: I test it using SoapUI and it works fine. Using fiddler, I see the call is made and the answer with all the data correct.
After researching for a while, I tried to alter the readerQuotas like maxStringContentLength, maxDepth etc. inside the xsd but no luck.
I got a little workaround for the getConfig method though: when I alter the Reference.cs file and change the System.DateTime variable types to string, it works fine but then I need to invoke a setConfig method, and that alteration brings another problem... Also, I've read that altering the webservice contract isn't a good practice.
I've been looking for a solution for a while now and here are some places I checked: this, this, this or this.
Can someone help?
Thanks
Seems I found a workaround for the problem:
in my reference.cs file under the service reference, I changed every DateTime and System.Nullable<System.DateTime> object to string ones - as I had tried before - being this way able to make the get method.
When trying to call the set method, I pass the dates with this:
vt.beginDate = DateTime.Now.ToString("o");
The ToString("o") seems to be the working solution in order to prevent serialization issues.
Here is my simple code, which works fine if called from php or any other client then adobe air. Same code also works from calling from SWF, there is fluorineFX code for other part of project as well, but then it doesn't do anything to break this.
I do find one thing that all POST calls were somehow changing to GET, which really amazes me. I would be so glad to get the answer for this. Thanks in Advance everyone. Below is the almost same code from my web service. with AIR code just under it.
[WebMethod(EnableSession = true)]
public bool Authenticate(string UserName,string Password)
{
try
{
if (Membership.ValidateUser(UserName, Password)){
FormsAuthentication.SetAuthCookie(UserName, true);
return true;
}
return false;
}
catch (Exception ex)
{
return false;
}
}
and my call from adobe AIR code as below
var ws:WebService = new WebService();
ws.wsdl="http://mysite.com/myservice.asmx?WSDL";
ws.useProxy=false;
ws.addEventListener(LoadEvent.LOAD,onWSDLLoad);
ws.loadWSDL();
ws.Authenticate.addEventListener(ResultEvent.RESULT,resultHandler);
ws.Authenticate.addEventListener(FaultEvent.FAULT,onLoginFaultHandler);
ws.Authenticate("usrname","password");
protected function onLoginFaultHandler(event:FaultEvent):void
{
Alert.show('Login Failed with messsage\r\n[ '+event.fault.faultString+' ]');
/* Error #1085: The element type "br" must be terminated
by the matching end-tag "</br>". */
/* checking the content value of fault event shows
same out put as http://mysite.com/myservice.asmx */
}
protected function onLoginResultHandler(event:ResultEvent):void
{
/* on success code */
}
This guy tells us following in page http://verveguy.blogspot.com/2008/07/truth-about-flex-httpservice.html
All HTTP GET requests are stripped of headers. It's not in the Flex stack so it's probably the underlying Flash player runtime.
All HTTP GET requests that have content type other than "application/x-www-form-url-encoded" are turned into POST requests
All HTTP POST requests that have no actual posted data are turned into GET requests. See 1/ and 2/
All HTTP PUT and HTTP DELETE requests are turned into POST requests. This appears to be a browser limitation that the Flash player is stuck with.
I do see my request above turns into GET, but then I DO have post values in it. OR if those are somehow are not sent or recorded by Web Service Object ?
This is pretty simple... The Flex XML parser uses strict xml checking, so all tags must be closed. If you can change the web service, then change all <br> tags to <br />.
I finally found the answer myself. turns out I was having cookies set to AutoDetect. Which meant that the AIR would call a URL and it would need to redirect to keep the cookie/session value in side the URI itself.
Now I switched that to UseCookies and Everything is back to normal. I could test this from a sample web services and realized it was the server-side that was doing something wrong. And from AIR to Browser that's the only difference of cookies.
Somehow nusoap for PHP is smart to know that there is AutoDetect or New URI of the Web Services available. But AIR couldn't locate that. Anyways Thanks everyone for helping me solve this.
Ok, its been a while since I've worked with a Web References. I need a refresher. I think I have about 80% of the code I need to get a response going but I'm missing something. Maybe you can help me :)
Given:
A web method called GetSomething in the list of methods when pointing to a .wsdl url.
This produces a few classes/objects:
GetSomethingRequest
GetSomethingCompletedEventHandler
GetSomethingCompletedEventArgs
myComplexType
Which I use to create this code:
void someMethodToTestResponse()
{
GetSomethingRequest request = new GetSomethingRequest();
// fill in the request
request.myComplexType.Property1 = "Blah";
request.myComplexType.Property2 = "Kachoo";
GetSomethingCompletedEventHandler handler = GetSomethingCompleted_Response;
//.... ok now what?
//handler.Invoke(???)
// at this point I'm supposed to send an object for source (request maybe?)
// and a new instance of GetSomethingCompletedEventArgs but that class is
// asking for stuff that makes me think that is not the right idea.
}
void GetSomethingCompleted_Response(object source, GetSomethingCompletedEventArgs args)
{
// get the result
var result = args.Result;
}
What am I doing wrong? What am I missing? Thanks in advance.
You don't need web service source codes. The web service can be implemented in Java. Creating service reference woks the same, as we really don't know what is on the other side.
So, try Add Service Reference in VS2008 and enter the url to working web service. VS will examine the wsdl on server and generate needed classes for you.
From than on, you just call the service as some ordinary method call. Meaning you don't have to fiddle with requests and http and such details. All that is hidden from you. Except in app.config where many WCF settings can be changed.
Ok, I figured out that I needed to find a Service type class. See this SO Post where it mentions:
private com.nowhere.somewebservice ws;
The issue was that the class they provide wasn't intellisensing for me and I figured it wasn't what I was looking for.
Here is how I would solve my problem:
blah.webservice.SomeMainServiceClass service = new SomeMainServiceClass();
GetSomethingRequest request = new GetSomethingRequest();
// fill in the request
request.myComplexType.Property1 = "Blah";
request.myComplexType.Property2 = "Kachoo";
object myResponse = service.GetSomething(request);
