I want to have a possibility to return complex response for requests in Web API. For example I want to return stream with some complex object.
I tried to do it with MultipartFormDataContent:
public static HttpResponseMessage GetMultipartResponse<T>(T responseData, Stream streamToReturn)
{
return new HttpResponseMessage
{
Content = new MultipartContent
{
new StreamContent(streamToReturn),
new ObjectContent<T>(responseData, new JsonMediaTypeFormatter())
}
};
}
I've got a normal HttpResponseMessage on server side. I can see by debugger how my Web API method returns this response, but on the client side I've got an error:
StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
Pragma: no-cache
X-SourceFiles: =?UTF-8?B?YzpcdXNlcnNccnVzdGFtX3NhbGFraHV0ZGlub3ZcZG9jdW1lbnRzXHZpc3VhbCBzdHVkaW8gMjAxM1xQcm9qZWN0c1xGaWxlU2VydmljZUFQSVxGaWxlU2VydmljZUFQSVxhcGlcZ2V0?=

X-AspNet-Version: 4.0.30319
X-Powered-By: ASP.NET
Content-Length: 1444
Content-Type: application/json; charset=utf-8
Expires: -1
}
There is no other exceptions on client or server side and i can't get some more information with turn on error detail:
config.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
UPDATE:
Try to read response on client side with:
var result = await response.Content.ReadAsMultipartAsync();
And got this exception:
Invalid 'HttpContent' instance provided. It does not have a content type header starting with 'multipart/'.
Where do I go wrong?
UPDATE 2:
I have normal response on the server side:
StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.MultipartContent, Headers:
{
Content-Type: multipart/multipart; boundary="3e6d3573-9031-41a7-b7f4-d1421bc1451d"
}
I found the error. I return my multipart content inside using:
using (var stream = MyFileStream())
{
var respone = MultipartResponseHelper.GetMultipartResponse(response, stream, Request);
return respone;
}
So it returns right response, but then stream inside multipartContent will disposed which is the reason of problem.

I am trying to call a POST method of Moosend API from my MVC application. The Post call is working fine from Postman but throwing error from controller.
The Code goes as below:
public async Task<ActionResult> CreateEmailList()
{
try
{
using (var httpClient = new HttpClient { BaseAddress = new Uri(Baseurl) })
{
httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Accept", "application/json");
httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Content-Type", "application/json");
using (var content = new StringContent("{ \"Name\": \"APIList\"}", System.Text.Encoding.Default, "application/json"))
{
using (var response = await httpClient.PostAsync("Mailing Lists/lists/create.json?apikey=0000", content))
{
string responseData = await response.Content.ReadAsStringAsync();
}
}
return View();
}
}
catch (Exception ex)
{
return View();
}
}
The Error I am getting is as below:
{StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

}}
Any suggestions on what am I missing here. Most of the POST example is similar to the code that I implemented.
I am trying to create an advert but everytime it gives an error at this line:
var response = await _client.PostAsync(new Uri($"{_baseAddress}/Create"),
new StringContent(jsonModel, Encoding.UTF8, "application/json")).ConfigureAwait(false);
I Added a breakpoint and it stops creating the response. Bellow is my function that i use
var advertApiModel = _mapper.Map<AdvertModel>(model);
var jsonModel = JsonConvert.SerializeObject(advertApiModel);
var response = await _client.PostAsync(new Uri($"{_baseAddress}/Create"),
new StringContent(jsonModel, Encoding.UTF8, "application/json")).ConfigureAwait(false);
var createAdvertResponse = await response.Content.ReadAsAsync<CreateAdvertResponse>().ConfigureAwait(false);
var advertResponse = _mapper.Map<AdvertResponse>(createAdvertResponse);
return advertResponse;
The error that terminal outputs is:

When I hover over var response after it passes it it shows this error:
{StatusCode: 404, ReasonPhrase: 'Not Found', Version: 1.1, Content: System.Net.Http.HttpConnectionResponseContent, Headers:

Okay, so I'm very new to using API's in code and I've been able to use a few that were actually pretty easy. But none of them required authentication. I've been trying to use Jira's REST API service via C#'s HttpClient class. See code below:
public void UpdateJiraIssue(string issueValue)
{
string url = $#"http://jira.mySite.com/rest/api/2/issue/{issueValue}/editmeta";
string jsonString = #"myNeatJsonData";
var content = new StringContent(jsonString, Encoding.UTF8, "application/json");
//Initialize Client
HttpClient apiClient = new HttpClient();
apiClient.BaseAddress = new System.Uri(url);
apiClient.DefaultRequestHeaders.Accept.Clear();
byte[] cred = UTF8Encoding.UTF8.GetBytes("username:password");
apiClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(cred));
apiClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
async Task RunJiraAPI()
{
using (HttpResponseMessage resp = await apiClient.PostAsync("editmeta", content))
{
if (resp.IsSuccessStatusCode)
{
var jsonSring = await resp.Content.ReadAsStringAsync();
}
}
}
RunJiraAPI();
return;
}
The problem I run into is that I get a 401 error (Authentication). Here's what my 'resp' object contains when I run the code:
resp: {StatusCode: 401, ReasonPhrase: ' ', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

}}

I need to work on my json string a bit to get it working right (which is why I didn't include what it actually contains), but once I get passed the authentication error, I'll probably actually change things to do a get Jira issue via the API so I can see all the json data returned that way. Then I'll edit my json string accordingly.
Any ideas what I'm doing wrong here?
You can pass in credentials assuming you have a username and an api token.
string credentials= string.Format("{0}:{1}", username, apitoken);
byte[] byteCredentials = UTF8Encoding.UTF8.GetBytes(credentials);
And in your apiClient you can use it like this.
apiClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteCredentials));
You need a username and api-token. Your api-token should be your login password.
I am having a big problem when trying to authenticate to QuickBlox's server using a Token.
The method I use is:
public static async Task<LoginResponse> GetLoginResponseAsync(string email, string password)
{
LoginResponse result = null;
using (var client = new HttpClient())
{
string token = QbProvider.SessionResponse.Session.Token;
LoginRequest request = new LoginRequest()
{
Email = email,
Password = password
};
using (var requestMessage = new HttpRequestMessage(HttpMethod.Post, LoginUrlRequest))
{
requestMessage.Headers.Authorization = new AuthenticationHeaderValue("QB-Token", token);
using (var response = await client.SendAsync(requestMessage))
{
string json = response.Content.ReadAsStringAsync().Result;
result = JsonConvert.DeserializeObject<LoginResponse>(json);
}
}
}
return result;
}
The server's response is:
{"errors":["Token is required"]}
And the headers (debugging) in the client object are:
{
StatusCode: 401, ReasonPhrase: 'Unauthorized', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
Access-Control-Allow-Origin: *

Content-Type: application/json; charset=utf-8

}
}
When I use the Token in Postman, the server's response is successfull.
Do you know what am I doing wrong?
Thank you so much in advance!
Regards.
Try adding your token header using requestMessage.Headers.Add("QB-Token", token) instead of your Authorization one – by #dukedukes
So I'm trying pass user data from one controller to another. I've been reading a lot about it here ---> http://www.dotnet-tricks.com/Tutorial/webapi/F2aL081113-Passing-multiple-complex-type-parameters-to-ASP.NET-Web-API.html and this guy seems to be doing exactly what I want to do, and he's using .PostAsJsonAsync to do it.
This is controller 1, which takes in user data and basically re-routes it to the other controller for authentication.
public ActionResult IDB(IDBUser i)
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost:64819");
HttpResponseMessage result = client.PostAsJsonAsync("/api/Participant/Authenticate", i).Result;
if (result.IsSuccessStatusCode)
{
return View();
}
else { // hits this breakpoint with 500 server error
return View("Index");
}
}
}
}
This seems to successfully make it to the other controller (below), as I'm getting a 500 error. However, I've got a breakpoint right at the beginning of the method, and it never seems to hit it.
[System.Web.Http.ActionName("Authenticate")]
[System.Web.Http.HttpPost]
public HttpResponseMessage Authenticate(IDBUser u)
{ //breakpoint it neve hits is on this line
bool Authenticate = false;
CredentialTester ct = new CredentialTester(u.password, u.username);
bool isAuthenticatedInt = ct.IntTest();
bool isAuthenticatedAcp = ct.AcpTest();
if (isAuthenticatedInt == true || isAuthenticatedAcp == true)
{
Authenticate = true;
return Request.CreateResponse(HttpStatusCode.OK, Authenticate);
}
else Authenticate = false;
return Request.CreateResponse(HttpStatusCode.NotAcceptable);
}
Any help is apprecitaed. Thanks everyone!
UPDATE
: I was able to look at the error and it is listed here:

it looks like there's a problem with my Access- Control-Origin. I've put the appropriate adjustments in my web.config file (I've had a similar error before) but no luck.
