I want to create lets say a master/core api.Want to check for a certain parameter value and redirect to a an external api hosted in the same server.I have an api with uri http://hello.test.com/auth which takes two auth params Username and Password.Now i add a third parameter lets say Area.
{
"Username":"jason",
"Password":"bourne",
"Area":"mars"
}
Now coming to the master api, if with this uri for example http://master.test.com/v1/mster and i pass Username, Password and Area,and if the Area has value of lets say "mars" it should call the external mars api having uri http://mars.test.com/auth ,do the auth the process and return the response in the master api.is this possible?
With my /auth api i have this controller returning the response :
[HttpPost]
[Route(ApiEndpoint.AUTH)]
public HttpResponseMessage Auth(Login authBDTO)
{
if (!ModelState.IsValid)
return Request.CreateResponse(HttpStatusCode.BadRequest, ModelState);
using (AccountBusinessService accountService = new AccountBusinessService())
{
var result = accountService.Auth(authBDTO);
return Request.CreateResponse(HttpStatusCode.OK, result);
}
}
Any Help Appreciated.Couldnt find this exact scenario in here.Sorry if too naive.
Found a workaround.This did the work.
[Route(ApiEndpoint.SAS)]
public IHttpActionResult esp(Login auth)
{
if (auth.Coop == "PMC")
{
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://localhost:60069/api/v1/auth");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = new JavaScriptSerializer().Serialize(new
{
Username = auth.UserName,
Password = auth.Password
});
streamWriter.Write(json);
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
dynamic obj = JsonConvert.DeserializeObject<ExpandoObject>(result);
obj.BaseUrl = "http://localhost:60069/api/v1";
return Ok(obj);
}
}
In ASP.Net Core 2.0, how can I POST data while redirecting to a third-party URL using Response.Redirect()?
Note: I have to POST this data without using the query-string.
Response.Redirect triggers a GET request which means that the only option is using a query string.
Can you trigger the redirection from the client (if any) in order to make a POST request?
You must use object if you want post data without using query string.
[HttpPost]
public IActionResult Search([FromBody] CustomerSearchRequestApiModel request)
{
if (request == null)
{
return BadRequest();
}
return Ok(request);
}
It is impossible to use Response.Redirect() to send Post request.
For a workaround, you could try HttpClient to send Post request and then return the reponse to the web browser with ContentResult as text/html.
Here is a demo code:
public async Task<ContentResult> HtmlView()
{
using (var formDataContent = new MultipartFormDataContent())
{
HttpClient client = new HttpClient();
Article article = new Article { ArticleName = "AN" };
formDataContent.Add(new StringContent("AN", Encoding.UTF8, "application/json"), "ArticleName");
using (HttpClient httpClient = new HttpClient())
{
HttpResponseMessage response = await httpClient.PostAsync(#"https://localhost:44393/Articles/Create", formDataContent);
return new ContentResult
{
ContentType = "text/html",
StatusCode = (int)response.StatusCode,
Content = await response.Content.ReadAsStringAsync()
};
}
}
}
Note
Change the HttpClient part to send the right request to your own third party url with validate parameters.
My API has an [HttpPatch] action which i need to invoke.
[HttpPatch("{id}")]
public StatusCodeResult Patch(int id, [FromBody]JsonPatchDocument<Reservation> patch)
{
Reservation res = Get(id);
if (res != null)
{
patch.ApplyTo(res);
return Ok();
}
return NotFound();
}
I am trying it from HttpClient class but it does not have .PatchAsync() method?
Also the parameter is of type JsonPatchDocument<Reservation> and so how to send it from client when invoking this action?
Please help
You have to create an HttpRequestMessage manually and send it via SendAsync:
var request = new HttpRequestMessage
{
RequestUri = new Uri("http://foo.com/api/foo"),
Method = new HttpMethod("patch"),
Content = new StringContent(json, Encoding.UTF8, "application/json-patch+json")
};
var response = await _client.SendAsync(request);
I'm trying to send my request with json content to web api, bit these value isn't automatically map to my object.
This is My API Action that result in null.
[HttpPost]
public IEnumerable<string> GetCustomerByName([FromBody] Request_GetCustomerByName request)
{
// Some Action
}
If I change parameter like below I can receive my data fine. So I wonder why my json string not automatically map to object.
[HttpPost]
public IEnumerable<string> GetCustomerByName([FromBody] dynamic request)
{
// Some action
}
This is where I send my request .
public ActionResult Index()
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:40175/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
Request_GetCustomerByName r = new Request_GetCustomerByName()
{
Customer = new Customer() { CustomerId = 1, CustomerName = "Name" },
RequestBase = new RequestBase() { Somefield="123"}
};
var json = new JavaScriptSerializer().Serialize(r);
HttpResponseMessage response = client.PostAsJsonAsync("api/values/GetCustomerByName", json).Result;
if (response.IsSuccessStatusCode)
{
var resVal = response.Content.ReadAsStringAsync().Result;
Response.Write(resVal);
}
}
return View();
}
Thanks, I've been stuck at this point for some hour...
You should probably inspect the Json string, this online json to c# object mapper might help: http://json2csharp.com/.
I have created a Web-api with following put method
public HttpResponseMessage Put(int id, [FromBody]DataModel model)
in the put method i pass the object and it get updated in the database. Its working i have checked it with fiddler.
Now in My MVC Application i call it using the following code
[HttpPost]
public JsonResult OrderSearch(DataModel model)
{
UpdateOrder(model).Wait();
if (putresult != null && putresult != string.Empty)
{
return Json(putresult);
}
else
{
return Json("Error in getting result");
}
}
private async Task UpdateOrder(DataModel model)
{
string json = JsonConvert.SerializeObject(model);
using (var client = new HttpClient())
{
client.BaseAddress = new Uri(url);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = client.PutAsync("api/values/"+ model.OrderNo,new StringContent(json)).Result;
if (response.IsSuccessStatusCode)
{
putresult = await response.Content.ReadAsAsync<string>();
}
}
}
But the code does not hit my Put method on the service and putresult remains blank. I try to search about PutAsync usage but could not find anything so please help.
Using .Wait in any ASP.NET runtime application is likely to result in a deadlock. I'm not sure how you are supposed to handle async methods in MVC.
