I am using soap client to make api call and try to mock the soap client in unit test and i get the stubbing argument mismatch
public Respproxy updateId(final ReqProxy req) {
Req request = createReq(req);
Rpy response = (Rpy) webServiceTemplate.marshalSendAndReceive("www.example.com/path", request);
return Respproxy.toBuilder().id(response.getId()).build();
}
private Req createReq() {
Req updateReq = new Req();
updateReq.setDate(Localtime.now());
return updateReq;
}
i tried
#Test
void testUpdateId() {
// Req mockReq = mock(Req.class);
Rpy mockRpy = mock(Rpy.class);
when(webServiceTemplate.marshalSendAndReceive("null/UpdateId", mockReq())).thenReturn(mockRpy);
updateIdSoapClient.updateId(Reqproxy.toBuilder.id(123));
verify(webServiceTemplate, times(1)).marshalSendAndReceive(mockReq());
}
private Req mockReq() {
Req updateReq = new Req();
updateReq.setDate(Localtime.now());
return updateReq;
}
#InjectMocks

Respproxy result = updateIdSoapClient.updateId(ReqProxy.tobuilder().id(123));
verify(webServiceTemplate).marshalSendAndReceive(urlCaptor.capture(), requestCaptor.capture());

So I have written a simple Azure Function (AF) that accepts (via Http Post method) an IFormCollection, loops through the file collection, pushes each file into an Azure Blob storage container and returns the url to each file.
The function itself works perfectly when I do a single file or multiple file post through Postman using the 'multipart/form-data' header. However when I try to post a file through an xUnit test, I get the following error:
System.IO.InvalidDataException : Multipart body length limit 16384 exceeded.
I have searched high and low for a solution, tried different things, namely;
Replicating the request object to be as close as possible to Postmans request.
Playing around with the 'boundary' in the header.
Setting 'RequestFormLimits' on the function.
None of these have helped so far.
The details are the project are as follows:

xUnit Test Project: targeting .netcoreapp3.1
Over to the xUnit Test project, basically I am trying to write an integration test. The project references the AF project and has the following classes:
TestHost.cs
public class TestHost
{
public TestHost()
{
var startup = new TestStartup();
var host = new HostBuilder()
.ConfigureWebJobs(startup.Configure)
.ConfigureServices(ReplaceTestOverrides)
.Build();
ServiceProvider = host.Services;
}
public IServiceProvider ServiceProvider { get; }
private void ReplaceTestOverrides(IServiceCollection services)
{
// services.Replace(new ServiceDescriptor(typeof(ServiceToReplace), testImplementation));
}
private class TestStartup : Startup
{
public override void Configure(IFunctionsHostBuilder builder)
{
SetExecutionContextOptions(builder);
base.Configure(builder);
}
private static void SetExecutionContextOptions(IFunctionsHostBuilder builder)
{
builder.Services.Configure<ExecutionContextOptions>(o => o.AppDirectory = Directory.GetCurrentDirectory());
}
}
}
TestCollection.cs
[CollectionDefinition(Name)]
public class TestCollection : ICollectionFixture<TestHost>
{
public const string Name = nameof(TestCollection);
}
HttpRequestFactory.cs: To create Http Post Request
public static class HttpRequestFactory
{
public static DefaultHttpRequest Create(string method, string contentType, Stream body)
{
var request = new DefaultHttpRequest(new DefaultHttpContext());
var contentTypeWithBoundary = new MediaTypeHeaderValue(contentType)
{
Boundary = $"----------------------------{DateTime.Now.Ticks.ToString("x")}"
};
var boundary = MultipartRequestHelper.GetBoundary(
contentTypeWithBoundary, (int)body.Length);
request.Method = method;
request.Headers.Add("Cache-Control", "no-cache");
request.Headers.Add("Content-Type", contentType);
request.ContentType = $"{contentType}; boundary={boundary}";
request.ContentLength = body.Length;
request.Body = body;
return request;
}
private static string GetBoundary(MediaTypeHeaderValue contentType, int lengthLimit)
{
var boundary = HeaderUtilities.RemoveQuotes(contentType.Boundary);
if (string.IsNullOrWhiteSpace(boundary.Value))
{
throw new InvalidDataException("Missing content-type boundary.");
}
if (boundary.Length > lengthLimit)
{
throw new InvalidDataException(
$"Multipart boundary length limit {lengthLimit} exceeded.");
}
return boundary.Value;
}
}
The MultipartRequestHelper.cs class is available here
And Finally the Test class:
[Collection(TestCollection.Name)]
public class UploadImagesTests
{
readonly UploadImages UploadImagesFunction;
public UploadImagesTests(TestHost testHost)
{
UploadImagesFunction = new UploadImages(testHost.ServiceProvider.GetRequiredService<IBlobService>());
}
[Theory]
[InlineData("testfile2.jpg")]
public async void HttpTrigger_ShouldReturnListOfUploadedUris(string fileNames)
{
var formFile = GetFormFile(fileNames);
var fileStream = formFile.OpenReadStream();
var request = HttpRequestFactory.Create("POST", "multipart/form-data", fileStream);
var response = (OkObjectResult)await UploadImagesFunction.Run(request);
//fileStream.Close();
Assert.True(response.StatusCode == StatusCodes.Status200OK);
}
private static IFormFile GetFormFile(string fileName)
{
string fileExtension = fileName.Substring(fileName.IndexOf('.') + 1);
string fileNameandPath = GetFilePathWithName(fileName);
IFormFile formFile;
var stream = File.OpenRead(fileNameandPath);
switch (fileExtension)
{
case "jpg":
formFile = new FormFile(stream, 0, stream.Length,
fileName.Substring(0, fileName.IndexOf('.')),
fileName)
{
Headers = new HeaderDictionary(),
ContentType = "image/jpeg"
};
break;
case "png":
formFile = new FormFile(stream, 0, stream.Length,
fileName.Substring(0, fileName.IndexOf('.')),
fileName)
{
Headers = new HeaderDictionary(),
ContentType = "image/png"
};
break;
case "pdf":
formFile = new FormFile(stream, 0, stream.Length,
fileName.Substring(0, fileName.IndexOf('.')),
fileName)
{
Headers = new HeaderDictionary(),
ContentType = "application/pdf"
};
break;
default:
formFile = null;
break;
}
return formFile;
}
private static string GetFilePathWithName(string filename)
{
var outputFolder = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
return $"{outputFolder.Substring(0, outputFolder.IndexOf("bin"))}testfiles\\{filename}";
}
}
The test seems to be hitting the function and req.ContentLength does have a value. Considering this, could it have something to do with the way the File Streams are being managed? Perhaps not the right way?
Any inputs on this would be greatly appreciated.
Thanks
UPDATE 1
As per this post, I have also tried setting the ValueLengthLimit and MultipartBodyLengthLimit in the Startup of the Azure Function and/or the Test Project as opposed to attributes on the Azure Function. The exception then changed to:
"The inner stream position has changed unexpectedly"
Following this, I then set the fileStream position in the test project to SeekOrigin.Begin. I started getting the same error:
"Multipart body length limit 16384 exceeded."
It took me a 50km bike ride and a good nights sleep but I finally figured this one out :-).
The Azure function (AF) accepts an HttpRequest object as a parameter with the name of 'req' i.e.
public async Task Run(
[HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = "images")] HttpRequest req)
The hierarchy of the files object in the HttpRequest object (along with the parameter names) is as follows:
HttpRequest -> req
FormCollection -> Form
FormFileCollection -> Files
This is what the AF accepts and one would access the files collection by using req.Form.Files
In my test case, instead of posting a FormCollection object, I was trying to post a Stream of a file to the Azure Function.
var formFile = GetFormFile(fileNames);
var fileStream = formFile.OpenReadStream();
var request = HttpRequestFactory.Create("POST", "multipart/form-data", fileStream);
As a result of this, req.Form had a Stream value that it could not interpret and the req.Form.Files was raising an exception.
In order to rectify this, I had to do the following:
Revert all changes made as part of UPDATE 1. This means that I removed the 'RequestFormLimits' settings from the Startup file and left them as attributes on the functions Run method.
Instantiate a FormFileCollection object and add the IFormFile to it
Instantiate a FormCollection object using this FormFileCollection as a parameter.
Add the FormCollection to the request object.
To achieve the above, I had to make the following changes in code.
Change 'Create' method in the HttpRequestFactory
public static DefaultHttpRequest Create(string method, string contentType, FormCollection formCollection)
{
var request = new DefaultHttpRequest(new DefaultHttpContext());
var boundary = $"----------------------------{DateTime.Now.Ticks.ToString("x")}";
request.Method = method;
request.Headers.Add("Cache-Control", "no-cache");
request.Headers.Add("Content-Type", contentType);
request.ContentType = $"{contentType}; boundary={boundary}";
request.Form = formCollection;
return request;
}
Add a private static GetFormFiles() method
I wrote an additional GetFormFiles() method that calls the existing GetFormFile() method, instantiate a FormFileCollection object and add the IFormFile to it. This method in turn returns a FormFileCollection.
private static FormFileCollection GetFormFiles(string fileNames)
{
var formFileCollection = new FormFileCollection();
foreach (var file in fileNames.Split(','))
{
formFileCollection.Add(GetFormFile(file));
}
return formFileCollection;
}
Change the Testmethod
The test method calls the GetFormFiles() to get a FormFileCollection then
instantiates a FormCollection object using this FormFileCollection as a parameter and then passes the FormCollection object as a parameter to the HttpRequest object instead of passing a Stream.
[Theory]
[InlineData("testfile2.jpg")]
public async void HttpTrigger_ShouldReturnListOfUploadedUris(string fileNames)
{
var formFiles = GetFormFiles(fileNames);
var formCollection = new FormCollection(null, formFiles);
var request = HttpRequestFactory.Create("POST", "multipart/form-data", formCollection);
var response = (OkObjectResult) await UploadImagesFunction.Run(request);
Assert.True(response.StatusCode == StatusCodes.Status200OK);
}
So in the end the issue was not really with the 'RequestFormLimits' but rather with the type of data I was submitting in the POST message.
I hope this answer provides a different perspective to someone that comes across the same error message.
Cheers.
yesterday I wanted to implement the DidReceiveData method to my NSUrlSessionDataDelegate. I noticed that the DidReceiveData method never gets called, and while I tried to track down the error I noticed that the other methods don't get called either. I'm pretty sure that the other methods worked before, I don't know if I changed something or maybe a Xamarin.iOS update is the cause, but maybe I am wrong here and they never worked.
I can confirm this problem for the methods DidReceiveResponse, DidReceiveData, and DidCompleteWithError.
Here is the code that creates the NSUrlSession and handles the response (note: I call IIS WebMethods that answer in XML):
public async Task<string> Invoke(string sUrl)
{
session = NSUrlSession.FromConfiguration(NSUrlSessionConfiguration.DefaultSessionConfiguration,
(INSUrlSessionDelegate)new SessionDelegate((x)=> _fehlermeldung = x), // Übergebe Methode damit der SessionDelegate die Fehlermeldung weiterreichen kann
null);
request = CreateGETRequest(CreateNSUrl(sUrl));
var data = session.CreateDataTaskAsync(request, out dataTask);
dataTask.Resume();
NSUrlSessionDataTaskRequest response = null;
try
{
response = await data;
}
catch (NSErrorException ex)
{
throw new Exception(ex.Error.LocalizedDescription + ": " + _fehlermeldung);
}
var doc = new XmlDocument();
doc.LoadXml(response.Data.ToString());
XmlNode elem = doc.DocumentElement.FirstChild;
return elem.InnerText;
}
private NSUrl CreateNSUrl(string url)
{
string converted = ((NSString)url).CreateStringByAddingPercentEscapes(NSStringEncoding.UTF8);
var nsurl = NSUrl.FromString(converted);
if (nsurl == null)
throw new Exception("Fehlerhafte URL: Aus '" + url + "' konnte kein gültiges NSUrl Objekt erzeugt werden.");
return nsurl;
}
private NSMutableUrlRequest CreateGETRequest(NSUrl nsurl)
{
return new NSMutableUrlRequest(nsurl) { HttpMethod = "GET" };
}
And here is my implementation of the session delegate:
private class SessionDelegate : NSUrlSessionDataDelegate, INSUrlSessionDelegate
{
private readonly Action<string> setFehler;
public SessionDelegate(Action<string> setFehler)
{
this.setFehler = setFehler;
}
public override void DidReceiveResponse(NSUrlSession session, NSUrlSessionDataTask dataTask, NSUrlResponse response, Action<NSUrlSessionResponseDisposition> completionHandler)
{
var http_response = response as NSHttpUrlResponse;
if (http_response == null)
{
setFehler($"Keine HTTP Url Antwort erhalten: {Environment.NewLine}'{response}'");
completionHandler(NSUrlSessionResponseDisposition.Cancel);
return;
}
var status_code = (int)http_response.StatusCode;
if (status_code == 200)
{
completionHandler(NSUrlSessionResponseDisposition.Allow);
}
else
{
setFehler($"Verbindung abgewiesen, HTTP Status: { status_code}, '{ http_response.ToString()}'");
completionHandler(NSUrlSessionResponseDisposition.Cancel);
}
}
public override void DidReceiveData(NSUrlSession session, NSUrlSessionDataTask dataTask, NSData data)
{
// THIS DOES NOT GET CALLED :-(
}
public override void DidCompleteWithError(NSUrlSession session, NSUrlSessionTask task, NSError error)
{
if (error != null)
{
task.Cancel();
var ex = new NSErrorException(error);
throw (ex);
}
}
public override void DidReceiveChallenge(NSUrlSession session, NSUrlSessionTask task, NSUrlAuthenticationChallenge challenge, Action<NSUrlSessionAuthChallengeDisposition, NSUrlCredential> completionHandler)
{
[...] // This is working fine for Client Cert Authentication or Basic Authentication
}
}
The DidReceiveChallenge method does get called and is working. I cut it out for readability.
All the other methods don't get called. I would like to know what I am doing wrong. You can find the same questions from native iOS users, but I can't figure out how to implement their solutions with Xamarin.iOS.
Any help is appreciated, thanks in advance.
I would like to see if/how it would be possible to plug into the deserialization process for a parameter that's decorated with the ServiceBusTrigger?
Say I have a function that looks like:
public static void HandleMessage([ServiceBusTrigger("myqueue")] MyCustomType myCustomType) { }
How would I go about taking over the deserialization? I know that there is a notion of an IArgumentBindingProvider and IArgumentBinding but it does not look like ServiceBusTrigger supports these concepts.
I know I can use GetBody<Stream>() and deserialize that way but I'd like to know if I can plug into the ServiceBusTrigger's pipeline. By the looks at the SDK, the ServiceBusTrigger has a hard coded list of IQueueArgumentBindingProviders and so I can't add my own.
If you have a look at the Azure WebJobs SDK Extensions, there is an overview on how to create your own bindings :
Binding Extensions Overview
Otherwise the ServiceBusConfiguration exposes a MessagingProvider property that allows you to intercept the ServiceBusTrigger pipeline:
private static void Main()
{
var sbConfig = new ServiceBusConfiguration()
{
MessagingProvider = // you implemetation of the MessagingProvider class goes here !!!
};
var config = new JobHostConfiguration();
config.UseServiceBus(sbConfig);
new JobHost(config).RunAndBlock();
}
Here is a simple skeleton of a MessagingProvider implementation:
public sealed class MyMessagingProvider : MessagingProvider
{
private readonly ServiceBusConfiguration _config;
public MyMessagingProvider(ServiceBusConfiguration config)
: base(config)
{
_config = config;
}
public override MessageProcessor CreateMessageProcessor(string entityPath)
{
return new MyMessageProcessor(_config.MessageOptions);
}
private class MyMessageProcessor : MessageProcessor
{
public MyMessageProcessor(OnMessageOptions messageOptions)
: base(messageOptions)
{
}
public override Task<bool> BeginProcessingMessageAsync(BrokeredMessage message, CancellationToken cancellationToken)
{
// Intercept the message before the execution of the triggerred function
return base.BeginProcessingMessageAsync(message, cancellationToken);
}
public override Task CompleteProcessingMessageAsync(BrokeredMessage message, FunctionResult result, CancellationToken cancellationToken)
{
// Intercept the message after the execution of the triggerred function and before being completed
return base.CompleteProcessingMessageAsync(message, result, cancellationToken);
}
}
}
So you're main function now looks like that:
private static void Main()
{
var sbConfig = new ServiceBusConfiguration();
sbConfig.MessagingProvider = new MyMessagingProvider(sbConfig);
var config = new JobHostConfiguration();
config.UseServiceBus(sbConfig);
new JobHost(config).RunAndBlock();
}
I am converting my AS3 codebase to TypeScript and run into this error:
AS3 code:
private function loadDataXml(assetsXml : String) : void {
var loader : URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, handleDataLoaded);
loader.load(new URLRequest(assetsXml));
}
private function handleDataLoaded(event : Event) : void {
var xml_data : XML = new XML(event.target.data);
parseData(xml_data);
.........
}
private function parseData(xml_data : XML) : void {
......
}
TypeScript code
private loadDataXml(assetsXml : string) {
var xmlRequest:XMLHttpRequest = new XMLHttpRequest();
xmlRequest.addEventListener("load",this.handleDataLoaded, false);
xmlRequest.open("GET", assetsXml, false);
xmlRequest.setRequestHeader("Content-Type", "text/xml");
xmlRequest.send(null);
}
private handleDataLoaded(evt:Event) {
var xmlDoc:Document = (<XMLHttpRequest> evt.target).responseXML;
this.parseXMLData(xmlDoc);
......
}
private parseData(xmlDoc:Document):void {
......
}
and I get this error "Uncaught TypeError: Object # has no method 'parseData'" because of this line xmlRequest.addEventListener.....
I have tried using arrow function but still couldn't fix it (and i don't think I use it correctly)
When you need to pass functions around use the new lambda syntax for member variables (introduced in TypeScript 0.9.1):
private loadDataXml(assetsXml : string) {
var xmlRequest:XMLHttpRequest = new XMLHttpRequest();
// you are passing a member function Use lambda to define this function:
xmlRequest.addEventListener("load",this.handleDataLoaded, false);
xmlRequest.open("GET", assetsXml, false);
xmlRequest.setRequestHeader("Content-Type", "text/xml");
xmlRequest.send(null);
}
private handleDataLoaded = (evt:Event) => { // Since you want to pass this around
var xmlDoc:Document = (<XMLHttpRequest> evt.target).responseXML;
this.parseXMLData(xmlDoc); // you will get the correct this here
......
}
private parseData(xmlDoc:Document):void {
......
}
Try binding to the scope
xmlRequest.addEventListener("load",this.handleDataLoaded.bind(this), false);
I have a WCF REST service that takes some parameters and sends an email. The template for the email is an MVC3 action. Essentially I want to render that action to a string.
If it were an ASP.NET WebForm, I could simply use Server.Execute(path, stringWriter, false). However when I plug in the path to my action, I get Error executing child request.
I have full access to HttpContext from my service (AspNetCompatibilityRequirementsMode.Allowed).
I know there are other answers out there for rendering actions to strings from within the context of a controller. How do I do this when I'm outside that world, but still on the same server (and, for that matter, in the same app)?
I cobbled together an answer based on several different google searches. It works, but I'm not 100% sure it's as lean as it could be. I'll paste the code for others to try.
string GetEmailText(TemplateParameters parameters) {
// Get the HttpContext
HttpContextBase httpContextBase =
new HttpContextWrapper(HttpContext.Current);
// Build the route data
var routeData = new RouteData();
routeData.Values.Add("controller", "EmailTemplate");
routeData.Values.Add("action", "Create");
// Create the controller context
var controllerContext = new ControllerContext(
new RequestContext(httpContextBase, routeData),
new EmailTemplateController());
var body = ((EmailTemplateController)controllerContext.Controller)
.Create(parameters).Capture(controllerContext);
return body;
}
