Getting error when a method is made for post request - flurl

When made I post request is made its giving internal server. Is the implementation of Flurl is fine or I am doing something wrong.
try
{
Models.PaymentPost paymentPost = new Models.PaymentPost();
paymentPost.Parts = new Models.Parts();
paymentPost.Parts.Specification = new Models.Specification();
paymentPost.Parts.Specification.CharacteristicsValue = new List<Models.CharacteristicsValue>();
paymentPost.Parts.Specification.CharacteristicsValue.Add(new Models.CharacteristicsValue { CharacteristicName = "Amount", Value = amount });
paymentPost.Parts.Specification.CharacteristicsValue.Add(new Models.CharacteristicsValue { CharacteristicName = "AccountReference", Value = accountId });
foreach (var item in extraParameters)
{
paymentPost.Parts.Specification.CharacteristicsValue.Add(new Models.CharacteristicsValue {
CharacteristicName = item.Key, Value = item.Value });
}
var paymentInJson = JsonConvert.SerializeObject(paymentPost);
var selfCareUrl = "http://svdt5kubmas01.safari/auth/processPaymentAPI/v1/processPayment";
var fUrl = new Flurl.Url(selfCareUrl);
fUrl.WithBasicAuth("***", "********");
fUrl.WithHeader("X-Source-System", "POS");
fUrl.WithHeader("X-Route-ID", "STKPush");
fUrl.WithHeader("Content-Type", "application/json");
fUrl.WithHeader("X-Correlation-ConversationID", "87646eaa-2605-405e-967c-56e8002b5");
fUrl.WithHeader("X-Route-Timestamp", "150935");
fUrl.WithHeader("X-Source-Operator", " ");
var response = await clientFactory.Get(fUrl).Request().PostJsonAsync(paymentInJson).ReceiveJson<IEnumerable<IF.Models.PaymentPost>>();
return response;
}
catch (FlurlHttpException ex)
{
dynamic d = ex.GetResponseJsonAsync();
//string s = ex.GetResponseStringAsync();
return d;
}

You don't need to do this:
var paymentInJson = JsonConvert.SerializeObject(paymentPost);
PostJsonAsync just takes a regular object and serializes it to JSON for you. Here you're effectively double-serializing it and the server is probably confused by that format.
You're also doing a lot of other things that Flurl can do for you, such as creating those Url and client objects explicitly. Although that's not causing errors, this is how Flurl is typically used:
var response = await selfCareUrl
.WithBasicAuth(...)
.WithHeader(...)
...
.PostJsonAsync(paymentPost)
.ReceiveJson<List<IF.Models.PaymentPost>>();

.NET Already Open DataReader

I get this error when running this code. I have looked for solution though I don't like the idea of using MARS as people have suggested as it may contain a lot of data, is there any other option here? Also can I edit a variable in a database without rewriting all of them as I do here, will this save server power or make no difference?
There is already an open DataReader associated with this Command which must be closed first.
public ActionResult CheckLinks(Link model)
{
var userId = User.Identity.GetUserId();
var UserTableID = db.UserTables.Where(c => c.ApplicationUserId == userId).First().ID;
foreach (var item in db.Links.Where(p => p.UserTable.ID == UserTableID))
{
string pageContent = null;
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(item.Obdomain);
HttpWebResponse myres = (HttpWebResponse)myReq.GetResponse();
using (StreamReader sr = new StreamReader(myres.GetResponseStream()))
{
pageContent = sr.ReadToEnd();
}
string live = "";
if (pageContent.Contains(item.Obpage))
{
live = "Yes";
}
else { live = "No"; }
var link = new Link { Obdomain = item.Obdomain, ClientID = item.ClientID, Obpage = item.Obpage, BuildDate = item.BuildDate, Anchor = item.Anchor, IdentifierID = item.IdentifierID, live = (Link.Live)Enum.Parse(typeof(Link.Live), live), UserTableID = item.UserTableID };
db.Entry(link).State = EntityState.Modified;
db.SaveChanges();
}
return RedirectToAction("Index");
}
Entity Framework allows only one active command per context at a time. You should add .ToList() at the end of the following statement:
db.Links.Where(p => p.UserTable.ID == UserTableID).ToList();
So your code could look like this:
var items = db.Links.Where(p => p.UserTable.ID == UserTableID).ToList();
foreach (var item in items)

Response on created context keeps giving me NullStream

I'm trying to write a middleware for batch requests i .net core 2.0.
So far the I have splitted the request, pipe each request on to the controllers.
The controllers return value, but for some reason the response on the created context that I parse to the controllers keeps giving me a NullStream in the body, so I think that there is something that I miss in my setup.
The code looks like this:
var json = await streamHelper.StreamToJson(context.Request.Body);
var requests = JsonConvert.DeserializeObject<IEnumerable<RequestModel>>(json);
var responseBody = new List<ResponseModel>();
foreach (var request in requests)
{
var newRequest = new HttpRequestFeature
{
Body = request.Body != null ? new MemoryStream(Encoding.ASCII.GetBytes(request.Body)) : null,
Headers = context.Request.Headers,
Method = request.Method,
Path = request.RelativeUrl,
PathBase = string.Empty,
Protocol = context.Request.Protocol,
Scheme = context.Request.Scheme,
QueryString = context.Request.QueryString.Value
};
var newRespone = new HttpResponseFeature();
var requestLifetimeFeature = new HttpRequestLifetimeFeature();
var features = CreateDefaultFeatures(context.Features);
features.Set<IHttpRequestFeature>(newRequest);
features.Set<IHttpResponseFeature>(newRespone);
features.Set<IHttpRequestLifetimeFeature>(requestLifetimeFeature);
var innerContext = _factory.Create(features);
await _next(innerContext);
var responseJson = await streamHelper.StreamToJson(innerContext.Response.Body);
I'm not sure what it is I'm missing in the setup, since innerContext.Response.Body isn't set.
One of the endpoints that I use for testing and that gets hit looks like this
[Route("api/[controller]")]
public class ValuesController : Controller
{
// GET api/values
[HttpGet]
public IEnumerable<string> Get()
{
return new string[] { "value1", "value2" };
}
}
I found the error, or two errors for it to work.
First I had to change my newResponse to
var newRespone = new HttpResponseFeature{ Body = new MemoryStream() };
Since HttpResponseFeature sets Body to Stream.Null in the constructor.
When that was done, then Body kept giving an empty string when trying to read it. That was fixed by setting the Position to Zero like
innerContext.Response.Body.Position = 0;

Result of the "R Script" without ColumnNames

I'm going crazy!
I'm using Azure Machine Learning and R Script. I deploy it as Web Service. I use sample code based on HttpClient.
using (var client = new HttpClient())
{
var scoreRequest = new
{
Inputs = new Dictionary<string, StringTable>() {
{
"input1",
new StringTable()
{
ColumnNames = new string[] {
"experts_estimates",
"experts_share_of_unique_information",
"avg_correlation",
"point_a",
"point_b",
"is_export_mode"
},
Values = new string[,] {
{
expertsEstimatesStr,
expertsShareOfUniqueInformationStr,
avgCorrelationStr,
pointAStr,
pointBStr,
isExportModeStr
},
}
}
},
},
GlobalParameters = new Dictionary<string, string>()
{
}
};
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", apiKey);
client.BaseAddress = new Uri(apiUrl);
// WARNING: The 'await' statement below can result in a deadlock
// if you are calling this code from the UI thread of an ASP.Net application.
// One way to address this would be to call ConfigureAwait(false)
// so that the execution does not attempt to resume on the original context.
// For instance, replace code such as:
// result = await DoSomeTask()
// with the following:
// result = await DoSomeTask().ConfigureAwait(false)
HttpResponseMessage response = await client.PostAsJsonAsync("", scoreRequest);
if (response.IsSuccessStatusCode)
{
string result = await response.Content.ReadAsStringAsync();
return result;
}
else
{
// Print the headers - they include the requert ID and the timestamp,
// which are useful for debugging the failure
var headers = response.Headers.ToString();
string responseContent = await response.Content.ReadAsStringAsync();
throw new Exception(responseContent, new Exception(headers));
}
}
and when I run code from Visual Studio I get:
but when I run code from Azure App Service I get:
Any ideas?
One solution is adding "edit metadata" module inside the model and rename the output columns. It'll be easy than using the code to name the columns.

Post data with free-jqgrid, what are the code in client and Web API side?

I am using ASP.NET MVC 6 Web API. In the View I use free-jqgrid.
Let's borrow Oleg's free jqgrid data to demonstrate my purpose. We already have the table shown.
Next I am going to add new Vendor. Please notify that there is primary key id(identity column) in the database. We don't want it displaying in the screen.
In VendorRespository.cs, I add the new Vendor as
public void AddVendor(Vendor item)
{
using (VendorDataContext dataContext = new VendorDataContext())
{
dataContext.Database.Connection.ConnectionString = DBUtility.GetSharedConnectionString(
"http://centralized.admin.test.com");
var newVendor = dataContext.Vendors.Create();
newVendor.Company = item.Company;
newVendor.ContactName = item.ContactName;
newVendor.ContactPhone = item.ContactName;
newVendor.UserName = item.UserName;
newVendor.UserKey = item.UserKey;
newVendor.Active = item.Active;
newVendor.FacilityId =item.FacilityId;
newVendor.ClientID = item.ClientID;
dataContext.SaveChanges();
}
}
My questions:
Not sure the script like?
<script>
API_URL = "/VendorManagement/";
function updateDialog(action) {
return {
url: API_URL
, closeAfterAdd: true
, closeAfterEdit: true
, afterShowForm: function (formId) { }
, modal: true
, onclickSubmit: function (params) {
var list = $("#jqgrid");
var selectedRow = list.getGridParam("selrow");
rowData = list.getRowData(selectedRow);
params.url += rowData.Id;
params.mtype = action;
}
, width: "300"
};
}
jQuery("#jqgrid").jqGrid('navGrid',
{ add: true, edit: true, del: true },
updateDialog('PUT'),
updateDialog('POST'),
updateDialog('DELETE')
);
In the controller, not sure what is the code?
// POST
public HttpResponseMessage PostVendor(Vendor item)
{
_vendorRespository.AddVendor(item);
var response = Request.CreateResponse<Vendor>(HttpStatusCode.Created, item);
string uri = Url.Link("DefaultApi", new { id = item.Id });
response.Headers.Location = new Uri(uri);
return response;
}
My code has many compiling errors such as
'HttpRequest' does not contain a definition for 'CreateResponse' and the best extension method overload 'HttpRequestMessageExtensions.CreateResponse(HttpRequestMessage, HttpStatusCode, Vendor)' requires a receiver of type 'HttpRequestMessage'
Please help me to get rid of the error and inappropriate code.
EDIT:
I borrowed the code snippet from here.
I need add the code such as
[Microsoft.AspNet.Mvc.HttpGet]
public dynamic GetVendorById(int pkey)
{
return null;
}
And
// POST
[System.Web.Http.HttpPost]
public HttpResponseMessage PostVendor(Vendor item)
{
_vendorRespository.AddVendor(item);
var response = Request.CreateResponse<Vendor>(HttpStatusCode.Created, item);
string uri = Url.Link("/VendorManagement/GetVendorById", new { id = item.pkey });
response.Headers.Location = new Uri(uri);
return response;
}

Retrieving CRM 4 entities with custom fields in custom workflow activity C#

I'm trying to retrieve all phone calls related to opportunity, which statecode isn't equal 1. Tried QueryByAttribute, QueryExpression and RetrieveMultipleRequest, but still has no solution.
Here some code i wrote.
IContextService contextService = (IContextService)executionContext.GetService(typeof(IContextService));
IWorkflowContext context = contextService.Context;
ICrmService crmService = context.CreateCrmService(true);
if (crmService != null)
{
QueryByAttribute query = new Microsoft.Crm.Sdk.Query.QueryByAttribute();
query.ColumnSet = new Microsoft.Crm.Sdk.Query.AllColumns();
query.EntityName = EntityName.phonecall.ToString();
query.Attributes = new string[] { "regardingobjectid" };
query.Values = new string[] { context.PrimaryEntityId.ToString() };
RetrieveMultipleRequest retrieve = new RetrieveMultipleRequest();
retrieve.Query = query;
retrieve.ReturnDynamicEntities = true;
RetrieveMultipleResponse retrieved = (RetrieveMultipleResponse)crmService.Execute(retrieve);
}
return ActivityExecutionStatus.Closed;
}
And almost same for QueryExpression
QueryExpression phCallsQuery = new QueryExpression();
ColumnSet cols = new ColumnSet(new string[] { "activityid", "regardingobjectid" });
phCallsQuery.EntityName = EntityName.phonecall.ToString();
phCallsQuery.ColumnSet = cols;
phCallsQuery.Criteria = new FilterExpression();
phCallsQuery.Criteria.FilterOperator = LogicalOperator.And;
phCallsQuery.Criteria.AddCondition("statuscode", ConditionOperator.NotEqual, "1");
phCallsQuery.Criteria.AddCondition("regardingobjectid", ConditionOperator.Equal, context.PrimaryEntityId.ToString();
I always get something like Soap exception or "Server was unable to proceed the request" when debugging.
To get exception details try to use following code:
RetrieveMultipleResponse retrieved = null;
try
{
retrieved = (RetrieveMultipleResponse)crmService.Execute(retrieve);
}
catch(SoapException se)
{
throw new Exception(se.Detail.InnerXml);
}
