I am using .NET Core with Boilerplate. I'm trying to unit test some new forms that require that I have nested objects with properties. The Integration Tests use AbpAspNetCoreIntegratedTestBase<Startup> which uses an instance of both HttpClient and TestServer. The client has various types of methods at its disposal. There are GetAsync, PostAsync, SendSync and PutAsync methods just to name a few.
I thought I had gotten comfortable with some of the methods and helper methods in this frame work and have been successful thus far. However, I have a form with an Model called Vendor, the Vendor has an Address Model as part of the view model. This is so I can reuse the Address View Model with other items in the application that also require Address(es).
One of the helpers that is used with BoilerPlate is GetUrl<TController>(string actionName, object queryStringParamsAsAnonymousObject) Since this is a Post from a form I'm attempting to use public Task<HttpResponseMessage> PostAsync(string requestUri, HttpContent content) No matter what I'm attempting to do, I'm getting a 400 Bad Request response and my test fails before it even gets inside the controller method. I'm at a loss of how to handle this.
Here are my Models:
VendorViewModel:
[AutoMap(typeof(Domains.Vendor))]
public class VendorViewModel : BaseViewModelEntity

As I attempt to debug what is happening. I've noticed that the VendorAddress properties that are sent via the test request do not match what the actual form post looks like when parsed in Chrome developer tools. In Chrome I see (example:
PointOfContact:"Tom Jerry"
IsActive:True
VendorAddress.Address1:"123 This Way"
VendorAddress.City: "Arlington")
I cannot get my test data into that same format, therefore its not binding correctly to my view models on post, and thus returns a 400 response and fails the test.
I have gotten it to work if I remove the Address View Model all together and put those properties as properties of the VendorViewModel. However, I would run into the same if not similar issue if I'm attempting to save a collection of objects along with the main view model.
I feel like there has to be a way to submit test form data via integration tests with boilerplate. I just need some missing piece to this puzzle.
The Solution that is working for both Post and Send Requests:
.NET Core has a QueryHelper class that will take a dictionary and a uri string and convert it into a url with querystring parameters. QueryHelpers.AddQueryString(string uri, IDictionary queryString) This is part of Microsoft.AspNetCore.WebUtilities.
Using this method I was able to properly prepare my formData. For a Post Request the Test would look like this
//Arrange
//Add Client Headers so User Auth and Permission Checkers work correctly
Client.DefaultRequestHeaders.Add("my-name", "admin");
Client.DefaultRequestHeaders.Add("my-id", "2");
//set up test data
var rawData = new Dictionary<string, string>(){{ "Id", "0"}, {"Name", "Controller Test Name"}, {"PointOfContact", "Tom Jerry"}
, {"Email", "Tom.Jerry#yolo.comy"}, {"CreationTime", $"{DateTime.Now}"}, {"LastModificationTime", ""}, {"IsActive", "true"}, {"AddressId", "0"}
, {"VendorAddress.Id", "0"}, {"VendorAddress.Address1", "123 This Way"}, {"VendorAddress.City", "Arlington"}, {"VendorAddress.State", "44"}, {"VendorAddress.Zip", "76001"}
, {"VendorAddress.Phone", "8175555555"}, {"VendorAddress.Fax", ""}, {"VendorAddress.IsActive", "true"}, {"VendorAddress.CreationTime", $"{DateTime.Now}"}, {"VendorAddress.LastModificationTime", ""}
};
var jsonData = JsonConvert.DeserializeObject(rawData);
//Serialize ViewModel to send with Post as part of the HttpContent object
var data = JsonConvert.SerializeObject(viewModelSave);
//actually get the url from helper method
var url = GetUrl<VendorController>(nameof(VendorController.SaveVendor));
var content = new StringContent(data, Encoding.UTF8, "application/x-www-form-urlencoded");
//Act
var response = await PostResponseAsObjectAsync<AjaxResponse>(url, content);
//Assert
var count = UsingDbContext(context => { return context.Municipalities.Count(x => x.IsActive); });
response.ShouldBeOfType<AjaxResponse>();
response.Result.ShouldNotBeNull();
count.ShouldBe(3);
Send Request Test would look like this
//Arrange
//Add Client Headers so User Auth and Permission Checkers work correctly
Client.DefaultRequestHeaders.Add("my-name", "admin");
Client.DefaultRequestHeaders.Add("my-id", "2");
//set up test data
var rawData = new Dictionary<string, string>(){{ "Id", "0"}, {"Name", "Controller Test Name"}, {"PointOfContact", "Tom Jerry"}
, {"Email", "Tom.Jerry#yolo.comy"}, {"CreationTime", $"{DateTime.Now}"}, {"LastModificationTime", ""}, {"IsActive", "true"}, {"AddressId", "0"}
, {"VendorAddress.Id", "0"}, {"VendorAddress.Address1", "123 This Way"}, {"VendorAddress.City", "Arlington"}, {"VendorAddress.State", "44"}, {"VendorAddress.Zip", "76001"}
, {"VendorAddress.Phone", "8175555555"}, {"VendorAddress.Fax", ""}, {"VendorAddress.IsActive", "true"}, {"VendorAddress.CreationTime", $"{DateTime.Now}"}, {"VendorAddress.LastModificationTime", ""}
};
var jsonData = JsonConvert.DeserializeObject(rawData);
//Serialize ViewModel to send with Post as part of the HttpContent object

I have a web API application. I'm supposed to do a post to an endpoint. When l tried my API controller in postman, l get the error message "
Requested resource does not support HTTP 'POST'
I'm new to Web API so any help and suggestions are welcomed.
This is my model class:
namespace Products.Models
{
public class Prouct
{
public string ProductID { get; set; }
public string ProductName { get; set; }
public string ProductPrice { get; set; }
public string VoucherID { get; set; }
}
}
Here is my controller class
[RoutePrefix("api/products")]
public class ProductsController : ApiController
{
static HttpClient client = new HttpClient();
public IEnumerable<string> Get()
{
return new string[] { "value1", "value2" };
}
public string Get(int id)
{
return "value";
}
[Route("products")]
public async Task PostAsync(string ProductID, string ProductName, string ProductPrice,
string VoucherID)
{
Products p = new Products();
p.ProductID = ProductID;
p.ProductName = ProductName;
p.ProductPrice = ProductPrice;
p.VoucherID = VoucherID;
var client = new HttpClient { BaseAddress = new
Uri("http://localhost:51613/") };
var response = await
client.PostAsJsonAsync("api/products",
p);
if (response.IsSuccessStatusCode)
{
}
public void Put(int id, [FromBody]string value)
{
}
public void Delete(int id)
{
}
You need to specify HttpPost on PostAsync method. by default, it is [HttpGet].
[HttpPost]
[Route("products")]
public async Task PostAsync(string ProductID, string ProductName, string ProductPrice, string VoucherID)
{
// implementation
}
Looks like you're stuck in a loop. Why does the PostAsync method call itself after having been invoked? This will result in an endless request loop.
var client = new HttpClient { BaseAddress = new Uri("http://localhost:51613/") };
This is not related to the fact that the [HttpPost] attribute is required however.
Please observe that you are supposed to use [FromBody] . Also inside Postman (image attached) you have to choose "Raw" data with the product json with type as JSON(application.json).
[HttpPost]
[Route("products")]
public async Task PostAsync([FromBody] Products p)
{
var client = new HttpClient
{
BaseAddress = new
Uri("http://localhost:51613/")
};
var response = await
client.PostAsJsonAsync("api/products",
p);
if (response.IsSuccessStatusCode)
{
}
}
I have Customer and Address classes, something like this:
public class Customer
{
[PrimaryKey]
public int Id { get; set; }
public string CustomerName { get; set; }
public int ShippingAddressId { get; set; }
[ForeignKey("ShippingAddressId")]
public Address ShippingAddress { get; set; }
}
public class Address
{
[PrimaryKey]
public int Id { get; set; }
public string City { get; set; }
}
When I call a Web API to update the Customer, I pass an edited Customer object to this method. For example, I edit 2 properties: Customer.CustomerName and Customer.ShippingAddress.City
AuthenticationResult ar = await new AuthHelper().AcquireTokenSilentAsync();
if (ar.Token == null) return false;
using (var json = new StringContent(JsonConvert.SerializeObject(entity), UnicodeEncoding.UTF8, "application/json"))
using (HttpClient client = new HttpClient())
{
client.BaseAddress = new Uri(Settings.ApiUrl);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", ar.Token);
using (HttpResponseMessage response = await client.PutAsync("api/" + type.ToString() + "/" + id, json))
{
response.EnsureSuccessStatusCode();
return await InsertOrReplaceResponse(type, response);
}
}
Here is the Web API:
[HttpPut("{id}")]
public async Task<IActionResult> PutCustomer([FromRoute] int id, [FromBody] Customer customer)
{
_context.Entry(customer).State = EntityState.Modified;
await _context.SaveChangesAsync();
return new StatusCodeResult(StatusCodes.Status204NoContent);
}
However, only Customer.CustomerName gets updated. The foreign key data (Customer.ShippingAddress.City) isn't updated in the Address table.
Any idea what I'm doing wrong?
Thanks!
Generally, I would expect the child Address entity to be update as well because you use foreign key association which also should be the default for one-to-one mappings (see here for more details). However, it seems that something is not setup right and you get independent association behavior where you have to manage child entity state yourself. Should be a simple fix in your case:
_context.Entry(customer).State = EntityState.Modified;
_context.Entry(customer.ShippingAddress).State = EntityState.Modified;
Can anyone out there help me to understand
how to invoke the client method from server method using SignalR The server class resides in an CustomEvent handler in a different assembly.
I tried 3 different methods to invoke the method:
I named my hub as [HubName("notificationhub")]
Method1
Clients.addMessage(message);
This gives "Cannot perform runtime binding on a null reference"
Method 2
IHubContext context1 = GlobalHost.ConnectionManager.GetHubContext("notificationhub");
context1.Clients.addMessage('hello');
The client remained silent.
Method3
var hubConnection = new HubConnection("http://localhost:21120/");
var notification= hubConnection.CreateProxy("notificationhub");
hubConnection.Start().Wait();
notification.Invoke("Send", "Hello").Wait();
This method gives error : {"The remote server returned an error: (500) Internal Server Error."} To my surprise, i am able to invoke this method from a console application using the 3rd method.
what is the best solution for implementing this and what is the reason why i am not able to invoke the client method? Can anyone help me with this?
Regards
Vince
Here is how Im doing it, a bit a hack, but it works. It only works when calling hub from a controller, otherwise it wont work. Use UpdateHubFromController method.
public class UpdateFeedActivity : Hub
{
readonly IHubContext _hubContext ;
public UpdateFeedActivity()
{
_hubContext = _hubContext ?? GlobalHost.ConnectionManager.GetHubContext<UpdateFeedActivity>();
}
public void UpdateFeed(string groupname, string itemId, Enums.FeedActivityTypes activityType,
string userId="",
string actionResult1="",
string actionResult2="",
string actionResult3="")
{
Clients.Group(groupname).updateMessages(new FeedHubResponse
{
ItemId = itemId,
ActivityType = activityType.ToString(),
UserId = userId,
ActionResult1 = actionResult1,
ActionResult2 = actionResult2,
ActionResult3 = actionResult3
});
}
public void UpdateFeedFromController(string groupname, string itemId, Enums.FeedActivityTypes activityType,
string userId = "",
string actionResult1 = "",
string actionResult2 = "",
string actionResult3 = "")
{
_hubContext.Clients.Group(groupname).updateMessages(new FeedHubResponse
{
ItemId = itemId,
ActivityType = activityType.ToString(),
UserId = userId,
ActionResult1 = actionResult1,
ActionResult2 = actionResult2,
ActionResult3 = actionResult3
});
}
public void Join(string groupname)
{
Groups.Add(Context.ConnectionId, groupname);
}
}
public class FeedHubResponse
{
public string ItemId { get; set; }
public string UserId { get; set; }
public string ActionResult1 { get; set; }
public string ActionResult2 { get; set; }
public string ActionResult3 { get; set; }
public string ActivityType { get; set; }
public string Text { get; set; }
}
I have developed one REST WCF and to test post method I had made simple call and would like to return output in json format. Following is my SVC and code behind
Iservice:
[OperationContract ]
[WebInvoke(Method = "POST",
RequestFormat = WebMessageFormat.Xml,
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Bare,
UriTemplate = "heroku/resources")]
User PostData(User objUser);
Service.cs:
public User PostData(User objUser)
{
User usr = new User();
usr.id = 100;
List<string> lst = new List<string>();
lst.Add("MY_URL");
lst.Add("MY");
usr.config = lst;
usr.message = "msg";
return usr;
}
User class :
[DataContract(Namespace = "http://localhost/RestWCFDemo/UserData")]
public class User
{
[DataMember]
[JsonProperty]
public int id
{
get;
set;
}
[DataMember]
[JsonProperty]
public List<string> config
{
get;
set;
}
[DataMember]
[JsonProperty]
public string message
{
get;
set;
}
}
Now from aspx code behind file I have called this service and assign response of that service to textbox and result I am getting is: {"config":["MY_URL","MY"],"id":100,"message":"msg"} however I expected output in this format {"config":{...},"id":100,"message":"msg"} , main problem is [ ] instead of { }.
Hey Arun change from list to class object then you can get {} instead of []..
