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:
{
X-Robots-Tag: noindex, nofollow
X-Server-ID: 2

X-Powered-By: ASP.NET
Content-Length: 5054

}}
Any suggestions on what am I missing here. Most of the POST example is similar to the code that I implemented.

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:

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

}}
Status Code: Unauthorized
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 need to call an API from AppService by uri.
This is my API:
public ApiOutputBase Test_AddStudent(string name, int age, string address)
{
return new ApiOutputBase
{
Result = new Result { Status = true, Message = "OK,Test_AddStudent Done!" },
OuputValues = new List<object>() { name, age, address }
};
}
I use this Function to call it:
public async Task<bool> TestCallApi()
{
var client = new HttpClient { BaseAddress = new Uri("http://localhost/") };
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var testJson = "{\r\n \"name\": \"MyName\",\r\n \"age\": 25,\r\n \"address\": \"MyAddress\"\r\n}";
HttpResponseMessage response = await client.PostAsync("api/services/myApp/commonLookup/Test_AddStudent", new StringContent(testJson));
// Call api success
if (response.IsSuccessStatusCode)
{
}
return true;
}
I used Swagger to call Test_AddStudent successfully. The testJson was copied from Swagger when I call Test_AddStudent successfully.
After that, I used Swagger to call TestCallApi without any error, but when I tried to debug the value of HttpResponseMessage, it showed this error:
{
StatusCode: 400,
ReasonPhrase: 'Bad Request',
Version: 1.1,
Content: System.Net.Http.StreamContent,

Content-Length: 405

Expires: -1
}
}
Have I missed something?
I finally found the root cause: I passed the wrong input to the api:
Wrong:
var testJson = "{\r\n \"name\": \"MyName\",\r\n \"age\": 25,\r\n \"address\": \"MyAddress\"\r\n}";
HttpResponseMessage response = await client.PostAsync("api/services/myApp/commonLookup/Test_AddStudent", new StringContent(testJson));
Correct:
HttpResponseMessage response = await client.PostAsync("api/services/myApp/commonLookup/Test_AddStudent?name=MyName&age=25&address=MyAdress", "");
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: *
Cache-Control: no-cache
Date: Thu, 01 Jun 2017 12:05:29 GMT
QuickBlox-REST-API-Version: 0.1.1

X-XSS-Protection: 1; mode=block
Connection: keep-alive
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
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?=
Cache-Control: no-cache

Server: Microsoft-IIS/8.0
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.
