I'm trying to pass a object from .NET MVC to Web Service (VB.NET) suing SOAP.
Passing individual fields works but when I try to pass an object, it throws an error
Cannot convert from Project.Models.Table to Project.WebService.Table
REQUIREMENTS
To pass an Object from MVC to Web Service.
Below is my Web Service code.
Questions: Do I need to serialize once I get the object.
<WebMethod()>
Public Function FormData(ByVal obj As Table)
Dim sqlconn As New SqlConnection
Dim sqlcmd As New SqlCommand
Try
Dim formSerializer As New XmlSerializer(GetType(Table))
Using reader As TextReader = New StringReader(obj)
data = formSerializer.Deserialize(reader)
End Using
Below is my MVC Controller, I have added the Service Reference.
public ActionResult Submission(Table data)
{
Table obj = new Table();
FormService.WebServiceSoapClient client = new FormService.WebServiceSoapClient();
obj = client.FormData(data);
return obj;
}
The error is while passing the data object from Controller to Web Service.
The Table model class with all the fields are added in both the projects.
Your help is appreciated.
Thanks.
UPDATE
As per the suggestions of #Panagiotis Kanavos, I tried using AutoMapper. So below is the working code. I am able to store values to database. Please do let me know if its correct and secured way. Thanks.
CLIENT SIDE
public JsonResult PostMethod(Table data)
{
FormService.WebServiceSoapClient client = new FormService.WebServiceSoapClient();
var config = new MapperConfiguration(cfg => { cfg.CreateMap<Table, Table_WS>(); });
IMapper iMapper = config.CreateMapper();
var destination = iMapper.Map<Table, Table_WS>(data);
var result = client.FormData(destination);
WEB SERVICE
<WebMethod()>
Public Function FormData(ByVal Obj As Table_WS) As Table_WS
sqlconn.ConnectionString = CONNECTION_STRING
sqlcmd.Connection = sqlconn
sqlconn.Open()
sqlcmd.CommandType = Data.CommandType.StoredProcedure
sqlcmd.CommandText = "SPR_INSERT"
sqlcmd.Parameters.AddWithValue("#NAME", IIf(IsNothing(Obj.NAME), DBNull.Value, Obj.NAME))
Thank you for helping.
First of all, if you're passing that much data, I think you should POST it, not GET it cause you clearly attempt to send something, not retrieve.
Secondly - I don't know VB.NET, but I assume '' stands for comment so your code will always try to deserialize data as XML. You could try passing parameter to inform your web method which serialization method is used. Again - I'm not sure how it's done in VB.NET.
You cannot convert between the 2 tables.
Public Function FormData(ByVal obj As Table) is expecting Project.WebService.Table and you are passing in Project.Models.Table. I think that is the correct order.
You need to pass into client.FormData a Project.WebService.Table.
You will have to convert your Project.Models.Table to a Project.WebService.Table
Something like this, should work.
public ActionResult Submission(Table data)
{
var client = new FormService.WebService1();
var table = new FormService.Table();
table.FirstName = data.FirstName;
table.LastName = data.LastName;
var obj = client.FormData(table);
data.FirstName = obj.FirstName;
data.LastName = obj.LastName;
...
}
The only way to do this with serialization would to use JSON and pass it as a string to the web method, at that point you could convert into any class you want.

I am trying to get the full contents of my modules From Zoho to our local Server. The deluge code does work as it returns to me the data which is being sent via the API. However, once it reaches the API, it is null. Any idea?
Below is the deluge code:
// Create a map that holds the values of the new contact that needs to be created
evaluation_info = Map();
evaluation_info.put("BulkData",zoho.crm.getRecords("Publishers"));
data = Map();
data.put(evaluation_info);
response = invokeurl
[
url :"https://zohoapi.xxxxx.com/publisher/publish"
type :POST
parameters:data
connection:"zohowebapi"
];
info data; (data returns all the data from publishers)
Here is my ASP.NET core restful API. It does ping it and create the file but the content of the file is null.
Route("[controller]")]
[ApiController]
public class PublisherController : ControllerBase
{
[HttpGet("[action]"), HttpPost("[action]")]
public void Publish(string data)
{
(it's already null when it comes here. why?)
string JSONresult = JsonConvert.SerializeObject(data);
string path = #"C:\storage\journalytics_evaluationsv2.json";
using (var file = new StreamWriter(path, true))
{
file.WriteLine(JSONresult.ToString());
file.Close();
}
}
}
}
What am I missing? Thank you
After contacting Zoho support, the solution he offered was to loop through the data in order to get all the contents from a module (if they are more than 200 records. With the solution provided, one doesn't really need the deluge code anymore as long as you have the ZOHO api set to your account in code. This was my final solution. This solution is not scalable at all. It's best to work with the BULK CSV.
// Our own ZohoAPI which lets us connect and authenticate etc. Yours may look slightly different
ZohoApi zohoApi = new ZohoApi();
zohoApi.Initialize();
ZCRMRestClient restClient = ZCRMRestClient.GetInstance();
var allMedicalJournals = new List<ZCRMRecord>();
for (int i = 1; i <= 30; i++)
{
List<ZCRMRecord> accountAccessRecords2 =
restClient.GetModuleInstance("Journals").SearchByCriteria("Tag:equals:MedicalSet", i, 200).BulkData.ToList();
foreach (var newData in accountAccessRecords2)
allMedicalJournals.Add(newData);
}
As part of ML automation process I want to dynamically create new AutoML model. I'm using C# (.net framework) and Google.Cloud.AutoML.V1.
After trying to run CreateDataSet code:
var autoMlClient = AutoMlClient.Create();
var parent = LocationName.FromProjectLocation(_projectId, _locationId);
var dataset = new Google.Cloud.AutoML.V1.Dataset();
dataset.DisplayName = "NewDataSet";
var response = autoMlClient.CreateDataset(parent, dataset);
I get the following error:
Field: dataset.dataset_metadata; Message: Required field not set
According to this user manual I should set Dataset Metadata Type, but the list contains only specific types of classifications (Translation/ImageClassifications etc.), I can't find a simple classification type.
How do I create a simple classification data set with the API ? in the AutoML UI its just with a simple button click ("NEW DATASET") - and have to provide only name & region - no classification type.
I also tried to set:
dataset.TextClassificationDatasetMetadata =
new TextClassificationDatasetMetadata() { ClassificationType = ClassificationType.Multiclass };
But I was unable to import data to it (got too many errors of invalid inputs from the input CSV file), I guess its related to the reason that the input format is not suitable for Text Classification.
UPDATE
I've just notice that the Nuget works with AutoML v1 but v1 beta does contains TablesDatasetMetadata Dataset Metadata Type for normal classifications. I'm speechless.
I also experienced this scenario today while creating a dataset using the NodeJS client. Since the Google AutoML table service is in the beta level you need to use the beta version of the AutoML client. In the Google cloud documentation they have used the beta client to create a dataset.
In NodeJS importing the beta version require('#google-cloud/automl').v1beta1.AutoMlClient instead of importing the normal version (v1) require('#google-cloud/automl').v1 worked for me to successfully execute the create dataset functionality.
In C# you can achieve the same through a POST request. Hope this helps :)
After #RajithaWarusavitarana comment, and my last question update , below is the code that did the trick. The token is being generated by GoogleClientAPI nuget and AutoML is handled by REST.
string GcpGlobalEndPointUrl = "https://automl.googleapis.com";
string GcpGlobalLocation = "us-central1"; // api "parent" parameter
public string GetToken(string jsonFilePath)
{
var serviceAccountCredentialFileContents = System.IO.File.ReadAllText(jsonFilePath);
var credentialParameters = NewtonsoftJsonSerializer.Instance.Deserialize<JsonCredentialParameters>(serviceAccountCredentialFileContents);
var initializer = new ServiceAccountCredential.Initializer(credentialParameters.ClientEmail)
{
Scopes = new List<string> { "https://www.googleapis.com/auth/cloud-platform" }
};
var cred = new ServiceAccountCredential(initializer.FromPrivateKey(credentialParameters.PrivateKey));
string accessToken = cred.GetAccessTokenForRequestAsync("https://oauth2.googleapis.com/token").Result;
return accessToken;
}
public void GetDataSetList(string projectId, string token)
{
var restClient = new RestClient(GcpGlobalEndPointUrl);
var createDataSetReqUrl = $"v1beta1/projects/{projectId}/locations/{GcpGlobalLocation}/datasets";
var createDataSetReq = new RestRequest(createDataSetReqUrl, Method.GET);
createDataSetReq.AddHeader("Authorization", $"Bearer {token}");
var createDatasetResponse = restClient.Execute(createDataSetReq);
createDatasetResponse.Dump();
}
I took the token generation code from google-api-dotnet-client Test File
I am new to Google APIs. I want to know how to call Google Dialogflow API in C# to get intent form the input text. But I can't find any example to call Dialogflow using C#.
Please provide some example to call Dialogflow from C#.
If I understand your question correctly you want to call the DialogFlow API from within a C# application (rather than writing fulfillment endpoint(s) that are called from DialogFlow. If that's the case here's a sample for making that call:
using Google.Cloud.Dialogflow.V2;
...
...
var query = new QueryInput
{
Text = new TextInput
{
Text = "Something you want to ask a DF agent",
LanguageCode = "en-us"
}
};
var sessionId = "SomeUniqueId";
var agent = "MyAgentName";
var creds = GoogleCredential.FromJson("{ json google credentials file)");
var channel = new Grpc.Core.Channel(SessionsClient.DefaultEndpoint.Host,
creds.ToChannelCredentials());
var client = SessionsClient.Create(channel);
var dialogFlow = client.DetectIntent(
new SessionName(agent, sessionId),
query
);
channel.ShutdownAsync();
In an earlier version of the DialogFlowAPI I was running into file locking issues when trying to re-deploy a web api project which the channel.ShutDownAsync() seemed to solve. I think this has been fixed in a recent release.
This is the simplest version of a DF request I've used. There is a more complicated version that passes in an input context in this post:
Making DialogFlow v2 DetectIntent Calls w/ C# (including input context)
(Nitpicking: I assume you know DialogFlow will call your code as specified/registered in the action at DialogFlow? So your code can only respond to DialogFlow, and not call it.)
Short answer/redirect:
Don't use Google.Apis.Dialogflow.v2 (with GoogleCloudDialogflowV2WebhookRequest and GoogleCloudDialogflowV2WebhookResponse) but use Google.Cloud.Dialogflow.v2 (with WebhookRequest and WebhookResponse) - see this eTag-error. I will also mention some other alternatives underneath.
Google.Cloud.Dialogflow.v2
Using Google.Cloud.Dialogflow.v2 NuGet (Edit: FWIW: this code was written for the beta-preview):
[HttpPost]
public dynamic PostWithCloudResponse([FromBody] WebhookRequest dialogflowRequest)
{
var intentName = dialogflowRequest.QueryResult.Intent.DisplayName;
var actualQuestion = dialogflowRequest.QueryResult.QueryText;
var testAnswer = $"Dialogflow Request for intent '{intentName}' and question '{actualQuestion}'";
var dialogflowResponse = new WebhookResponse
{
FulfillmentText = testAnswer,
FulfillmentMessages =
{ new Intent.Types.Message
{ SimpleResponses = new Intent.Types.Message.Types.SimpleResponses
{ SimpleResponses_ =
{ new Intent.Types.Message.Types.SimpleResponse
{
DisplayText = testAnswer,
TextToSpeech = testAnswer,
//Ssml = $"<speak>{testAnswer}</speak>"
}
}
}
}
}
};
var jsonResponse = dialogflowResponse.ToString();
return new ContentResult { Content = jsonResponse, ContentType = "application/json" }; ;
}
Edit: It turns out that the model binding may not bind all properties from the 'ProtoBuf-json' correctly (e.g. WebhookRequest.outputContexts[N].parameters),
so one should probably use the Google.Protobuf.JsonParser (e.g. see this documentation).
This parser may trip over unknown fields, so one probably also wants to ignore that. So now I use this code (I may one day make the generic method more generic and thus useful, by making HttpContext.Request.InputStream a parameter):
public ActionResult PostWithCloudResponse()
{
var dialogflowRequest = ParseProtobufRequest<WebhookRequest>();
...
var jsonResponse = dialogflowResponse.ToString();
return new ContentResult { Content = jsonResponse, ContentType = "application/json" }; ;
}
private T ParseProtobufRequest<T>() where T : Google.Protobuf.IMessage, new()
{
// parse ProtoBuf (not 'normal' json) with unknown fields, else it may not bind ProtoBuf correctly
// https://github.com/googleapis/google-cloud-dotnet/issues/2425 "ask the Protobuf code to parse the result"
string requestBody;
using (var reader = new StreamReader(HttpContext.Request.InputStream))
{
requestBody = reader.ReadToEnd();
}
var parser = new Google.Protobuf.JsonParser(JsonParser.Settings.Default.WithIgnoreUnknownFields(true));
var typedRequest = parser.Parse<T>(requestBody);
return typedRequest;
}
BTW: This 'ProtoBuf-json' is also the reason to use WebhookResponse.ToString() which in turn uses Google.Protobuf.JsonFormatter.ToDiagnosticString.
Microsoft's BotBuilder
Microsoft's BotBuilder packages and Visual Studio template.
I havent't used it yet, but expect approximately the same code?
Hand written proprietary code
A simple example of incoming request code (called an NLU-Response by Google) is provided by Madoka Chiyoda (Chomado) at Github. The incoming call is simply parsed to her DialogFlowResponseModel:
public static async Task<HttpResponseMessage> Run([...]HttpRequestMessage req, [...]CloudBlockBlob mp3Out, TraceWriter log)
...
var data = await req.Content.ReadAsAsync<Models.DialogFlowResponseModel>();
Gactions
If you plan to work without DialogFlow later on, please note that the interface for Gactions differs significantly from the interface with DialogFlow.
The json-parameters and return-values have some overlap, but nothing gaining you any programming time (probably loosing some time by starting 'over').
However, starting with DialogFlow may gain you some quick dialog-experience (e.g. question & answer design/prototyping).
And the DialogFlow-API does have a NuGet package, where the Gactions-interface does not have a NuGet-package just yet.
i am new with MongoDB, and i can't find GridFS.
Where can i get GridFS to store files now ?
I can get it this way:
mongoClient = new MongoClient(Settings.Default.MongoDB);
var server = mongoClient.GetServer();
MongoDatabase = server.GetDatabase(Settings.Default.DatabaseName);
MongoDatabase.GridFS...
but GetServer() method is obsolete.
if I get database as here:
MongoDatabase2 = mongoClient.GetDatabase(Settings.Default.DatabaseName);
MongoDatabase2.GridFS... not working
Then i receive IMongoDatabase instead MongoDatabase, and i didnt have GridFS.
Heureka!! Got it! Give me the Nobel prize! :)
var grid = new MongoGridFS(new MongoServer(new MongoServerSettings {Server = new MongoServerAddress(host, port)}), databaseName, new MongoGridFSSettings());
grid.Upload(file.InputStream, file.FileName, new MongoGridFSCreateOptions
{
Id = imageId,
ContentType = file.ContentType
});
I have the same problem. I did find something I thought would solve my problem, the class MongoGridFS. My problem now is that it takes a MongoServer, as it's first arg and times out when I give it a new instance or complains about a connectionstring not found.
var grid = new MongoGridFS(new MongoServer(new MongoServerSettings { Server = new MongoServerAddress(Settings.Default.WizdooMongoConnectionString) }), Settings.Default.WizdooMongoDatabaseName, new MongoGridFSSettings());
grid.Upload(file.InputStream, file.FileName, new MongoGridFSCreateOptions
{
Id = imageId,
ContentType = file.ContentType
});
//Yealds: The settings property 'ConnectionString' was not found.
I suppose I need to give it a connectionstring, but I've been able to do CRUD fine in MongoDB without it. So weird for this service to require it all of a sudden. Maybe you can make it work for you though. I'm going to look in to it more when I have time... should work with correct config. If you get it to work pls give me a hint! Good luck! :)
I am currently working on an MVC site that will hopefully consume an old .asmx Web Service. The documentation for the Web Service provides the following example:
// Construct a request object
TrimRequest request = new TrimRequest();
// Construct a RecordStringSearchClause, with type
// TitleWord, and argument "reef"
RecordStringSearchClause clause = new RecordStringSearchClause();
clause.Type = RecordStringSearchClauseType.TitleWord;
clause.Arg = "reef";
// Construct a record search, and put our search clause in it
WorkerPortalTest.TRIMWS.RecordSearch search = new WorkerPortalTest.TRIMWS.RecordSearch();
search.Items = new RecordClause[] { clause };
// If we had more than one clause, it would look like:
// search.Items = new RecordClause[] { clause1, clause2, clause3 }
// Put our search operation into our TrimRequest
request.Items = new Operation[] { search };
// Send it off. Whatever comes back will be in response
Engine engine = new Engine();
engine.Credentials = newSystem.Net.NetworkCredential(username, password);
TrimResponse response = engine.Execute(request);
As a fairly new C# programmer I understand all of it apart from the last three lines. I have never seen or used the Engine object and Visual Studio does not know of it either.. I looked through MSDN and found this page but it said it was deprecated.
I am just looking for some pointers in the right direction to call the Web Service and receive back the desired result.
Thanks.
Engine is an example of the webservice class. It calls a method in Engine class known as "Execute"..
