I'm trying to send list of objects from MVC to WEBAPI using below methods. API is able to able receive the list from controller but, value of each item in the list is either empty/null on API side.
Can anyone please help me to fix this?
Controller Method:
private List<FCM.Models.Facility> GetFacilityDetails()
{
var url = "http://localhost:64664/";
var facilies = new List<Facility>();
facilies.Add( new Facility{ FCLT_ID = 100, FCLT_NM = "Facility 100" });
facilies.Add( new Facility{ FCLT_ID = 200, FCLT_NM = "Facility 200" });
facilies.Add( new Facility{ FCLT_ID = 300, FCLT_NM = "Facility 300" });
var json = JsonConvert.SerializeObject(facilies);
var _client = new RestClient(url);
var request = new RestRequest("api/facility/details", Method.GET) { RequestFormat = DataFormat.Json };
facilies.ForEach(fclt =>
request.AddParameter("facilites", fclt, ParameterType.GetOrPost));
var response = _client.Execute<List<FCM.Models.Facility>>(request);
if (response.Data == null)
{
throw new Exception(response.ErrorMessage);
}
return response.Data;
}
WebAPI method:
[Route("api/facility/details")]
public IEnumerable<Facility> GetFullAddress([FromUri] IEnumerable<Facility> facilities)
{
return null;
}
Like the comment suggested you maybe want to issue a POST request instead, but if you would like to send an array with a GETrequest you could do it like this (with System.Net.Http.HttpClient):
Add a Format method to you Facility class:
public class Facility
{
public int FCLT_ID { get; set; }
public string FCLT_NM { get; set; }
public string Format(int index)
{
return $"[{index}].FCLT_ID={FCLT_ID}&[{index}].FCLT_NM={FCLT_NM}";
}
}
Define a class which can format the array values:
public class FacilityList : List<Facility>
{
public string Format()
{
var builder = new StringBuilder();
for (var i = 0; i < Count; i++)
{
builder.Append(this[i].Format(i));
if(i != Count -1)
{
builder.Append("&");
}
}
return builder.ToString();
}
}
And then issue the request:
var client = new HttpClient()
{
BaseAddress = new Uri("http://localhost:64664/"),
DefaultRequestHeaders = {Accept = {new MediaTypeWithQualityHeaderValue("application/json")}}
};
var facilities = new FacilityList
{
new Facility {FCLT_ID = 100, FCLT_NM = "Facility 100"},
new Facility {FCLT_ID = 200, FCLT_NM = "Facility 200"},
new Facility {FCLT_ID = 300, FCLT_NM = "Facility 300"}
};
var format = facilities.Format();
var response = client.GetAsync("api/facility/details?" + format).GetAwaiter().GetResult();
var result = JsonConvert.DeserializeObject<IEnumerable<Facility>>(response.Content.ReadAsStringAsync().GetAwaiter().GetResult());
This will bind to your controller action:
[Route("api/facility/details")]
public IHttpActionResult Get([FromUri] IEnumerable<Facility> facilities)
{
// Do stuff..
return Ok(facilities);
}

I am trying to insert data from a .csv file into my database, but anytime I upload data, the record is empty.
This is my code so far:
[HttpPost]
public async Task<IActionResult> ImportFromExcel(IFormFile formFile)
{
var data = new MemoryStream();
await formFile.CopyToAsync(data);
data.Position = 0;
TextReader reader = new StreamReader(data);
var csvReader = new CsvReader(reader, new CsvConfiguration(System.Globalization.CultureInfo.CurrentCulture)
{
HasHeaderRecord = true,
HeaderValidated = null,
MissingFieldFound = null
});
var Name = csvReader.GetField(0).ToString();
var dep = "cccccccccc";
var pos = "bbbbbbbbbbb";
await dcx.Participants.AddAsync(new Participant
{
Name = Name,
Position = pos,
Department = dep,
});
dcx.SaveChanges();
return ViewComponent("ViewParticipants");
}
This is the sample data in my database table:
As long as the headers of your CSV match up to the names of the columns in your database, you should be able to do something like this. If the names don't match, you can use .Name("CsvColumnName") in ParticipantMap to add the name of the column in the CSV file. Example: Map(r => r.Description).Name("MyCsvDescription");.
[HttpPost]
public async Task<IActionResult> ImportFromExcel(IFormFile formFile)
{
var data = new MemoryStream();
await formFile.CopyToAsync(data);
data.Position = 0;
var conf = new CsvConfiguration(CultureInfo.InvariantCulture)
{
HasHeaderRecord = true,
HeaderValidated = null,
MissingFieldFound = null,
BadDataFound = context =>
{
bad.Add(context.RawRecord);
}
};
using (TextReader reader = new StreamReader(data))
using (var csvReader = new CsvReader(reader, config)) {
csvReader.Context.RegisterClassMap<ParticipantMap>();
var records = csvReader.GetRecords<Participant>().ToList();
var dep = "cccccccccc";
var pos = "bbbbbbbbbbb";
records.ForEach(r =>
{
r.Department = dep;
r.Position = pos;
});
await dcx.Participants.AddRangeAsync(records);
dcx.SaveChanges();
}
return ViewComponent("ViewParticipants");
}
public class ParticipantMap : ClassMap<Participant>
{
public ParticipantMap()
{
AutoMap(CultureInfo.InvariantCulture);
Map(r => r.Department).Ignore();
Map(r => r.Position).Ignore();
}
}
In my opinion, you should call csvReader.Read() to read the file row first.
You can refer to the following test code, it works fine.
[HttpPost]
public async Task<IActionResult> ImportFromExcel(IFormFile formFile)
{
var data = new MemoryStream();
await formFile.CopyToAsync(data);
data.Position = 0;
using (var reader = new StreamReader(data))
{
var bad = new List<string>();
var conf = new CsvConfiguration(CultureInfo.InvariantCulture)
{
HasHeaderRecord = true,
HeaderValidated = null,
MissingFieldFound = null,
BadDataFound = context =>
{
bad.Add(context.RawRecord);
}
};
using (var csvReader = new CsvReader(reader, conf))
{
while (csvReader.Read())
{
var Name = csvReader.GetField(0).ToString();
var pos = csvReader.GetField(1).ToString();
var dep = csvReader.GetField(2).ToString();
await dcx.Participants.AddAsync(new Participant
{
Name = Name,
Position = pos,
Department = dep,
});
dcx.SaveChanges();
}
}
}
return ViewComponent("ViewParticipants");
}

Am trying to create a an azure function that is triggered in a Logic Apps,
The functions purpose is to web crawl certain web sites, take the desired information, compare that with a a SQL Server database in Azure, compare if we already have that information if not add it.
My issue is that when ever i run it I get the Server 500 error, I assume its accessing the database that cause. Help?

500 HTTP status code is a generic code which means that the server was not able to process the request due to some issues, First step would be to add some exception handling to your function and see if the failure occurs and where it occurs.
On Side note, you should not use HTTP client in the way used in the code, you should not new it up every time your function executes, this client should be static in nature. Refer Manage connections in Azure Functions

""query"": {
""match_all"": { }

Func<SearchRequestParameters, SearchRequestParameters> requestParameters = a =>
a.SearchType(SearchType.Scan).Scroll(TimeSpan.FromSeconds(60));
var searchResult = await client.LowLevel.SearchAsync<SearchResponse<T>>(indexName, mappingName, query , requestParameters)
if (searchResult.Body.IsValid)
{
var scrollNo = 0;
var results = await client.ScrollAsync<T>("10s", searchResult.Body.ScrollId);
while (results.Documents.Any())
{

scrollNo++;

Would like to pull all data using scroll while passing raw json query. but scroll is not working properly while passing json raw query. Can anyone help on this ?.
Your example is nearly there but not quite; you're missing a closing brace for the while loop to collect all documents before returning the custom response.
Here's an example I just ran on the Stackoverflow data set, to return all questions tagged with nest
private IElasticClient _client;
void Main()
{
var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));
var defaultIndex = "default-index";
var connectionSettings = new ConnectionSettings(pool);
_client = new ElasticClient(connectionSettings);
var query = #"
{
""query"": {
""term"": {
""tags"": {
""value"": ""nest""
}
}
}
}";
var result = RunScrollAsync(query).Result.Dump();
}
private async Task<Customresponse<Question>> RunScrollAsync(string query)
{
var scrollTime = "10s";
// omit the .SearchType(Scan) which is deprecated. Not
// specifying means the first response contains the first set
// of documents
var esResponse = await _client.LowLevel.SearchAsync<SearchResponse<Question>>(
"posts",
"question",
query, r => r.Scroll(TimeSpan.FromSeconds(10))).ConfigureAwait(false);
if (esResponse.Body.IsValid && esResponse.Body.Documents.Any())
{
// assume you have less than 2,147,483,647 documents to return?
var documents = new List<Question>((int)esResponse.Body.Total);
documents.AddRange(esResponse.Body.Documents);
var scrollNo = 0;
var response = await _client.ScrollAsync<Question>(scrollTime, esResponse.Body.ScrollId).ConfigureAwait(false);;
// keep scrolling until no more documents are returned
while (response.Documents.Any())
{
documents.AddRange(response.Documents);
scrollNo++;
response = await _client.ScrollAsync<Question>(scrollTime, response.ScrollId).ConfigureAwait(false);;
}
return new Customresponse<Question>
{
Documents = documents,
total = response.Total
};
}
// return an empty result.
// Or throw an exception, or log - whatever you need to do
return new Customresponse<Question>
{
Documents = Enumerable.Empty<Question>(),
total = 0
};
}
public class Customresponse<T>
{
public IEnumerable<T> Documents { get; set; }
public long total { get; set; }
}
This returns all 342 questions, with a total of 342 (Data set is from June 2016).
I have a requirement where I need to update a user's google calendar when an event is inserted in the application's fullcalendar. I am using the peleyal's example for ASP.Net MVC and OAuth for Google API (using GoogleAuthorizationCodeFlow and AuthorizationCodeMvcApp) to handle this. I believe I have set up the credentials right in the google developer console as well.
I am able to create events on the google calendar locally without a problem. But from the azure deployed site I am not able to create the event. There are no exceptions/errors either. Is there anything that needs to be done from azure side to be able to create events and to use Google API?
var finalREsult = System.Threading.Tasks.Task.Run(async () =>
{
try
{
var result = await new AuthorizationCodeMvcApp(this, new AppFlowMetaData()).AuthorizeAsync(cancellationToken);
if (result.Credential != null)
{
var service = new CalendarService(new BaseClientService.Initializer
{
HttpClientInitializer = result.Credential,
ApplicationName = "****"
});
var startDate = patientappointment.DateScheduled.Value.ToUniversalTime();
var endDate = patientappointment.DateScheduled.Value.AddMinutes(patientappointment.AppointmentLengthMinutes).ToUniversalTime();
var myEvent = new Event
{
Summary = string.Format("{0}/{1}/{2} - {3}", patientappointment.CurrentUserName, patientappointment.LocationName, patientappointment.RoomName, patientappointment.Notes),
Location = "Ireland",
Start = new EventDateTime

DateTime = new DateTime(startDate.Year, startDate.Month, startDate.Day, startDate.Hour, startDate.Minute, 0),
TimeZone = "(GMT+01:00) Dublin"
},
End = new EventDateTime
{
DateTime = new DateTime(endDate.Year, endDate.Month, endDate.Day, endDate.Hour, endDate.Minute, 0),

},
Recurrence = new String[] { "RRULE:FREQ=WEEKLY;BYDAY=MO" }
// Attendees = new List<EventAttendee> { new EventAttendee { Email = "**0#gmail.com" } },
};
EventsResource.InsertRequest request = service.Events.Insert(myEvent, "******#group.calendar.google.com");
request.Execute();
}
}
catch (Exception ex)
{
throw ex;
}
Looking at the requests information, I dont see the request being sent to first autheticate and get the auth code from the deployed site.
