How to CREATE POST IN C# to an endpoint on BMC REMEDY API to create a ticket with files submited in form-data?

I have this problem. i have to submit a file (or not) to an endpoint on an API of bmc.
the KEY:entry with the VALUE:data_entry.txt is the json to send with the values, as the same of the body.
The attach-z2AF_WIAttachment1 is the file i want to submit. I'm it's always throuwing some error, or headers invalid, or filetype not valid, but in postman is working.
I cant convert to C#.
this is my code so far, or now.
try
{
//authentication
var dict = new Dictionary<string, string>();
dict.Add("username", "applicationUsernameJonDoe");
dict.Add("password", "applicationPassowrdXPTO");
var clientLogin = new HttpClient();
var req = new HttpRequestMessage(HttpMethod.Post, Endpoint_loginITSM) { Content = new FormUrlEncodedContent(dict) };
var res = clientLogin.SendAsync(req); //.Result.ToString();
var body = res.GetAwaiter().GetResult().Content.ReadAsStringAsync();
//pedido de criação de registo
using (var client = new HttpClient())
{
client.Timeout = TimeSpan.FromMinutes(10);
var request = new HttpRequestMessage
{
RequestUri = new Uri(Endpoint_CreateITSM),
Method = HttpMethod.Post
};
request.Headers.Add("Authorization", body.Result.ToString());
if (!string.IsNullOrEmpty(registos.Objeto.fileName))
{
registos.Objeto.Registo.z2AF_WIAttachment1 = registos.Objeto.fileName;
}
string json = JsonConvert.SerializeObject(new { values = registos.Objeto });
byte[] file_bytes = System.Convert.FromBase64String(registos.Objeto.fileEncoded);
MemoryStream memoryStream = new MemoryStream();
using (BsonDataWriter writer = new BsonDataWriter(memoryStream))
{
JsonSerializer serializer = new JsonSerializer();
serializer.Serialize(writer, registos.Objeto.Registo);
}
var data_entry_bytes = memoryStream.ToArray();
// we need to send a request with multipart/form-data
var multiForm = new MultipartFormDataContent();
ByteArrayContent data_entry_json_content = new ByteArrayContent(data_entry_bytes);
data_entry_json_content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
data_entry_json_content.Headers.ContentDisposition = new ContentDispositionHeaderValue("entry")
{
FileName = "data_entry.txt",
Name = "entry",
};
multiForm.Add(data_entry_json_content);
ByteArrayContent z2AF_WIAttachment1_content = new ByteArrayContent(file_bytes);
z2AF_WIAttachment1_content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
z2AF_WIAttachment1_content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attach-z2AF_WIAttachment1")
{
FileName = registos.Objeto.fileName,
Name = "attach-z2AF_WIAttachment1",
};
multiForm.Add(z2AF_WIAttachment1_content);
request.Content = multiForm;
var result = await client.SendAsync(request);
var resBody = result.Content.ReadAsStringAsync().Result.ToString();//.ConfigureAwait(false);
dynamic _resBody = JsonConvert.DeserializeObject<dynamic>(resBody);
string registoID = _resBody["values"].SysRequestID;
return ResponseHandler<string>.Resposta(false, "resposta api bit criar registos", registoID);
}
}
catch (Exception e)
{
string classname = this.GetType().Name;
CentralLibrary.Services.ErrorLoggingService.ErrorLogsForCore(classname, e, _env.WebRootPath);
return ResponseHandler<string>.Resposta(true, "EXCEPTION : resposta api bit criar registos", e.Message);
}

Here is a better solution.
I had a problem with the last, but for someone who doesnt wnat to use de library RestClient that's the way. But this is working 100% and i have JsonProperty Names for NewtonSoft.Json so this workin with names like
[JsonProperty("z1D Action")]
public string z1D_Action { get; } = "CREATE";
so, my code is, and using an object AbrirRegistosITSM with nested object AbrirRegistosITSM_com_anexo my final solution is
AbrirRegistosITSM _registo = new AbrirRegistosITSM
{
Values = new AbrirRegistosITSM_com_anexo
{
Details = registos.Objeto.Comentario,
Customer_Login = registos.username,
Login_ID = registos.username,
SR_Type_Field_3 = registos.Objeto.Tipologia,
SR_Type_Field_28 = registos.Objeto.Categoria,
z2AF_WIAttachment1 = registos.Objeto.FicheiroNome
}
};
var client = new RestClient(Endpoint_CreateITSM);
string baseFolder = _env.WebRootPath;
string pathDir = Path.Combine(baseFolder, DateTime.Now.ToString().Replace('/', '_').Replace(' ', '_').Replace(':', '_'));
Directory.CreateDirectory(pathDir);
string pathDirFile = Path.Combine(pathDir, registos.Objeto.FicheiroNome);
File.WriteAllBytes(pathDirFile, Convert.FromBase64String(registos.Objeto.FicheiroBase64));
string pathEntryDir = Path.Combine(baseFolder, DateTime.Now.ToString().Replace('/', '_').Replace(' ', '_').Replace(':', '_'));
Directory.CreateDirectory(pathEntryDir);
string patnEntrydirFile = Path.Combine(pathEntryDir, "data_entry.txt");
File.WriteAllText(patnEntrydirFile, JsonConvert.SerializeObject(new { values = _registo.Values }));
var request = new RestRequest();
request.Method = Method.Post;
request.AddHeader("Authorization", token);
request.AddFile("entry", patnEntrydirFile, "application/json");
request.AddFile("attach-z2AF_WIAttachment1", pathDirFile, "application/octet-stream");
var reqbody = JsonConvert.SerializeObject(_registo);
request.AddParameter("application/json", reqbody, ParameterType.RequestBody);
RestResponse response = client.Execute(request);
var respostaBody = response.Content.ToString();//.ConfigureAwait(false);
dynamic _respostaBody = JsonConvert.DeserializeObject<dynamic>(respostaBody);
string _registoID = _respostaBody["values"]["Request Number"];
then i return the request number that what i need, but you have a lot of values there. I use NewtonSoft remember that. I dont use JsonSerializer because i wasn't able to save the json property names with spaces with JsonSerializer.

I'm not entirely sure what's going wrong here. It can be a lot of things, but I might be able to get you going. The last couple of weeks I build a HttpClient that sends a file with metadata to a GraphQL endpoint.
Please ensure the following:
I think you are requesting the file through an call. Please store it in a variable as a Byte[] using the ReadAsByteArrayAsync(). Do note decode it or cast it to a string or anything. You'll just corrupt the file.
var response = client.GetAsync(fileUrl);
var downloadedFile = await response.Result.Content.ReadAsByteArrayAsync();
The following code might not work entirely in your case, but should help you get going building the right request, since I'm also sending metadata in my request containing the file extension and some other information. This will most likely send the file to your API without a file extension.
using (var client = new HttpClient())
{
var file = new byte[] { 1, 2, 3 };
var fileToUpload = new ByteArrayContent(file);
var formData = new MultipartFormDataContent
{
{ fileToUpload, "entry", "passInFileExtensionForExample"},
{ fileToUpload, "attach-z2AF_WIAttachment1", "passInFileExtensionForExample" }
};
var response = await client.PostAsync("endpoint", formData);
}
Add the Bearer token using the following code:
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);

So i've discover the solution for my problem. I'm gonna to submit only one file. I have to submit also the Json body as a file "entry" "data_entry.txt" and for HttpRequestMessage you have to have a content MultipartFormDataContent and here you can add as many files as you have. i have to convert the Json body to a file ( in this case i converted to binary Array) with the name entry, and the name of the file data_entry.txt, but it's what the endpoint needs, so...whatever.
using (var client = new HttpClient())
{
client.Timeout = TimeSpan.FromMinutes(10);
MultipartFormDataContent content = new MultipartFormDataContent();
//adicionar ficheiro
byte[] file_bytes = System.Convert.FromBase64String(registos.Objeto.fileEncoded);
StreamContent fileContent = new StreamContent(new MemoryStream(file_bytes));
fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
{
Name = "files[attach-z2AF_WIAttachment1]",
FileName = registos.Objeto.fileName
};
fileContent.Headers.ContentType = MediaTypeHeaderValue.Parse("application/octet-stream");
content.Add(fileContent);
//adicionar ficheiro entry
StreamContent entryStreamContent = new StreamContent(new MemoryStream(ObjectToByteArray(registos.Objeto.Registo)));
entryStreamContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
{
Name = "files[entry]",
FileName = "data_entry.txt"
};
entryStreamContent.Headers.ContentType = MediaTypeHeaderValue.Parse("application/json");
content.Add(entryStreamContent);
var request = new HttpRequestMessage
{
RequestUri = new Uri(Endpoint_CreateITSM),
Method = HttpMethod.Post,
Content= content
};
request.Headers.Add("Authorization", body.Result.ToString());
string json = JsonConvert.SerializeObject(new { values = registos.Objeto.Registo});
request.Content = new ByteArrayContent(Encoding.UTF8.GetBytes(json));
request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
var resposta = await client.SendAsync(request);
var respostaBody = resposta.Content.ReadAsStringAsync().Result.ToString();//.ConfigureAwait(false);
dynamic _respostaBody = JsonConvert.DeserializeObject<dynamic>(respostaBody);
string _registoID = _respostaBody["values"].SysRequestID;
return ResponseHandler<string>.Resposta(false, "resposta api bit criar registos", _registoID);
So this is my solution. and it's working :)

Including Authentication in the Header of a POST Request using ASP.NET Core

I'm trying to make a request to receive a session Id to integrate with a payment gateway.
var m = System.Text.Encoding.Unicode.GetBytes("merchant." + merchant_Id + ":" + merchant_pass);
var b64Val = Convert.ToBase64String(m);
var SerSession = JsonConvert.SerializeObject(sessionRequest);
var client = new HttpClient();
string _ContentType = "application/json";
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(_ContentType));
client.DefaultRequestHeaders.Add("Authorization", String.Format("Basic {0}", b64Val));
var _UserAgent = "d-fens HttpClient";
client.DefaultRequestHeaders.Add("User-Agent", _UserAgent);
HttpContent _Body = new StringContent(SerSession);
]_Body.Headers.ContentType = new MediaTypeHeaderValue(_ContentType);
HttpResponseMessage response;
response = await client.PostAsync(api_URL, _Body);
var content = response.Content.ReadAsStringAsync().Result;
return Ok(content);
I am getting (Invalid credentials) and I am sure the credentials I am using are correct. I have tested them in Python and PHP.

try this
var authenticationString = $"{merchant_Id}:{merchant_pass}";
var base64EncodedAuthenticationString = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(authenticationString));
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", base64EncodedAuthenticationString);

How to send firebase notification to multiple topics

I have done like below for single topic to send notification which is working great:
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(ConfigurationManager.AppSettings["FirebaseAPI"]);
client.DefaultRequestHeaders
.Accept
.Add(new MediaTypeWithQualityHeaderValue("application/json"));//ACCEPT header
client.DefaultRequestHeaders
.Authorization = new AuthenticationHeaderValue("key", "=" + ConfigurationManager.AppSettings["projectKey"]);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "relativeAddress");
//How to Send more Id's loop it with the array
var data = new
{
to = string.Concat("/topics/", 121),
notification = new
{
body = "test",
title = "FIRE alert"
}
};
var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(data);
request.Content = new StringContent(json, Encoding.UTF8, "application/json");//CONTENT-TYPE header
var resultArray = client.PostAsync("send", request.Content);
return resultArray.Result.Content.ReadAsStringAsync();

How to send a file and form data with HttpClient in C#

How can I send a file and form data with the HttpClient?
I have two ways to send a file or form data. But I want to send both like an HTML form. How can I do that? Thanks.
This is my code:
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
var client = new HttpClient();
var requestContent = new MultipartFormDataContent();
filename = openFileDialog1.FileName;
array = File.ReadAllBytes(filename);
var imageContent = new ByteArrayContent(array);
imageContent.Headers.ContentType = MediaTypeHeaderValue.Parse("audio/*");
requestContent.Add(imageContent, "audio", "audio.wav");
var values = new Dictionary<string, string>
{
{ "token", "b53b99534a137a71513548091271c44c" },
};
var content = new FormUrlEncodedContent(values);
requestContent.Add(content);
var response = await client.PostAsync("localhost", requestContent);
var responseString = await response.Content.ReadAsStringAsync();
txtbox.Text = responseString.ToString();
}

Here's code I'm using to post form information and a csv file
using (var httpClient = new HttpClient())
{
var surveyBytes = ConvertToByteArray(surveyResponse);
httpClient.DefaultRequestHeaders.Add("X-API-TOKEN", _apiToken);
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var byteArrayContent = new ByteArrayContent(surveyBytes);
byteArrayContent.Headers.ContentType = MediaTypeHeaderValue.Parse("text/csv");
var response = await httpClient.PostAsync(_importUrl, new MultipartFormDataContent
{
{new StringContent(surveyId), "\"surveyId\""},
{byteArrayContent, "\"file\"", "\"feedback.csv\""}
});
return response;
}
This is for .net 4.5.
Note the \" in the MultipartFormDataContent. There is a bug in MultipartFormDataContent.
In 4.5.1 MultipartFormDataContent wraps the data with the correct quotes.
Update: This link to the bug no longer works since the have retired Microsoft Connect.

Here's code I'm using a method to send file and data from console to API
static async Task uploaddocAsync()
{
MultipartFormDataContent form = new MultipartFormDataContent();
Dictionary<string, string> parameters = new Dictionary<string, string>();
//parameters.Add("username", user.Username);
//parameters.Add("FullName", FullName);
HttpContent DictionaryItems = new FormUrlEncodedContent(parameters);
form.Add(DictionaryItems, "model");
try
{
var stream = new FileStream(#"D:\10th.jpeg", FileMode.Open);
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(#"http:\\xyz.in");
HttpContent content = new StringContent("");
content.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
{
Name = "uploadedFile1",
FileName = "uploadedFile1"
};
content = new StreamContent(stream);
form.Add(content, "uploadedFile1");
client.DefaultRequestHeaders.Add("Authorization", "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.dsfdsfdsfdsfsdfkhjhjkhjk.vD056hXETFMXYxOaLZRwV7Ny1vj-tZySAWq6oybBr2w");
var response = client.PostAsync(#"\api\UploadDocuments\", form).Result;
var k = response.Content.ReadAsStringAsync().Result;
}
catch (Exception ex)
{
}
}

Getting error while posting login info on ASP.NET WEB API call

I am getting this exception while trying to do a post call on a ASP.NET Web API. I am calling this from a Windows Universal App:
Type
'<>f__AnonymousType0`3[System.String,System.String,System.String]'
cannot be serialized. Consider marking it with the
DataContractAttribute attribute.
Here is my code:
var loginData = new { grant_type = "password", username = name, password = pass };
var queryString = "grant_type = password, username = " + name + ", password = " + pass;
HttpClient httpClient = new HttpClient();
try
{
string resourceAddress = "http://localhost:24721/Token";
//int age = Convert.ToInt32(this.Agetxt.Text);
//if (age > 120 || age < 0)
//{
// throw new Exception("Age must be between 0 and 120");
//}
string postBody = Serialize(loginData);
httpClient.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage wcfResponse = await httpClient.PostAsync(resourceAddress,
new StringContent(queryString, Encoding.UTF8));
}

Best guess is, you're getting that error because the serializer you're using doesn't support anonymous types. I would recommend trying to use Json.Net, which handles them nicely. I believe you can include it from NuGet.
If you reference the library in your project then you could modify your code like so:
var loginData = new { grant_type = "password", username = name, password = pass };
HttpClient httpClient = new HttpClient();
try
{
string resourceAddress = "http://localhost:24721/Token";
string postBody = Newtonsoft.Json.JsonConvert.SerializeObjectloginData);
var content = new StringContent(postBody, Encoding.UTF8, "application/json");
httpClient.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage wcfResponse = await httpClient.PostAsync(resourceAddress, content);
}

I found the solution. i updated the post data as key value pair and it worked.
using (var client = new HttpClient())
{
string resourceAddress = "http://localhost:24721/Token";
var requestParams = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>("grant_type", "password"),
new KeyValuePair<string, string>("username", name),
new KeyValuePair<string, string>("password", pass)
};
var requestParamsFormUrlEncoded = new FormUrlEncodedContent(requestParams);
var tokenServiceResponse = await client.PostAsync(resourceAddress, requestParamsFormUrlEncoded);
var responseString = await tokenServiceResponse.Content.ReadAsStringAsync();
var responseCode = tokenServiceResponse.StatusCode;
var responseMsg = new HttpResponseMessage(responseCode)
{
Content = new StringContent(responseString, Encoding.UTF8, "application/json")
};
return responseMsg;
}
