Postman form-data: How to program it inside a HttpRequestMessage?

I am doing a request through postman to a specific url but I set the form-data type in order to get data to the site like this:
Now I want to program this request inside C# but everything I tried so far is returning a 400 Bad Request response. This is what I tried:
public async Task<CheckAccessTokenModel> CheckAccessTokenAsync(string accessToken)
{
string uriString = "someurl";
var uri = new Uri(uriString);
try
{
using(var httpClient = new HttpClient())
{
var request = new HttpRequestMessage
{
Method = HttpMethod.Post,
RequestUri = uri
};
var ClientId = ConfigurationAccessor.Configuration["WebCredentials:ClientId"];
var Secret = ConfigurationAccessor.Configuration["WebCredentials:Secret"];
var authString = Convert.ToBase64String(Encoding.UTF8.GetBytes($"{ClientId}:{Secret}"));
request.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", authString);
MultipartFormDataContent content = new MultipartFormDataContent();
content.Add(new StringContent("token"), accessToken);
request.Content = content;
var response = await httpClient.SendAsync(request);
var checkTokenResponseData = await response.Content.ReadAsStringAsync();
//return new CheckAccessTokenModel { Active = true, Exp = 1647431224233 };
return JsonConvert.DeserializeObject<CheckAccessTokenModel>(checkTokenResponseData);
}
}
catch
{
return null;
}
}
I am doing it with the MultipartFormDataContent Object as suggested by many others here but it still won't work.
What can be the problem here?
EDIT: Wrong picture replaced

You can simply
request.Content = new StringContent($"token={accessToken}");
With form data I think it's something like this:
var data = new Dictionary<string, string>
{
{"token", acccessToken}
};
using var content = new FormUrlEncodedContent(data);
request.Content = content;

API request WaitingForActivation "Not yet computed" error via asp.net

this is my code via asp.net web form:
public string GetAccessToken()
{
ServicePointManager.Expect100Continue=true;
string accessToken = "";
System.Net.ServicePointManager.SecurityProtocol=System.Net.SecurityProtocolType.Tls12;
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
client.DefaultRequestHeaders.AcceptLanguage.Add(new StringWithQualityHeaderValue("en_US"));
var clientId = "<"+PAYPAL_CLIENT_ID+">";
var clientSecret = "<"+PAYPAL_SECRET_KEY+">";
var bytes = Encoding.UTF8.GetBytes(clientId+":"+clientSecret);
client.DefaultRequestHeaders.Authorization=new AuthenticationHeaderValue("Basic", Convert.ToBase64String(bytes));
var keyValues = new List<KeyValuePair<string, string>>();
keyValues.Add(new KeyValuePair<string, string>("grant_type", "client_credentials"));
var responseMessage = client.PostAsync("https://api.sandbox.paypal.com/v1/oauth2/token", new FormUrlEncodedContent(keyValues));
accessToken= responseMessage.Status.ToString();
}
return accessToken;
}
But I get this error:
Id = 9, Status = WaitingForActivation, Method = "{null}", Result = "{Not yet computed}" in AccessToken

client.PostAsync is an asynchronous method that returns a Task object. You either need to await it (this is the preferred approach), but that would require a change to the signature of the GetAccessToken() function (and probably to the upstream code) or simply do the following:
var responseTask = client.PostAsync("https://api.sandbox.paypal.com/v1/oauth2/token", new FormUrlEncodedContent(keyValues));
responseTask.Wait();
var responseMessage = responseTask.Result;

C# HttpClient.SendAsync causes error, cannot send a content-body with this verb-type

I am getting error cannot send a content-body with this verb-type. I am calling a GET Endpoint from a C# VSTO desktop application. What am I doing wrong.
public static string GetCentralPath(LicenseMachineValidateRequestDTO licenseMachine)
{
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", Properties.Settings.Default.Properties["JWT"].DefaultValue.ToString());
var request = new HttpRequestMessage
{
Method = HttpMethod.Get,
RequestUri = new Uri($"{Constants.URL.APIBase}licensemachine/GetCentralPath"),
Content = new StringContent(JsonConvert.SerializeObject(licenseMachine), Encoding.UTF8, "application/json"),
};
using (HttpResponseMessage response = client.SendAsync(request).GetAwaiter().GetResult()) // Causing ERROR
{
var result = GetStringResultFromHttpResponseMessage(response, true);
if (string.IsNullOrEmpty(result))
return null;
return JsonConvert.DeserializeObject<string>(result);
}
}
}
The end point looks like the following:
[HttpGet("GetCentralPath")]
public async Task<IActionResult> GetCentralPath(LicenseMachineValidateRequestDTO dto)
{
// Some code
}

fix the action, you cannot send body data with get, see this post
HTTP GET with request body
[HttpPost("GetCentralPath")]
public async Task<IActionResult> GetCentralPath(LicenseMachineValidateRequestDTO dto)
and fix request , replace Method = HttpMethod.Get with Post, this is what generates an error
var request = new HttpRequestMessage
{
Method = HttpMethod.Post,
RequestUri = new Uri($"{Constants.URL.APIBase}licensemachine/GetCentralPath"),
Content = new StringContent(JsonConvert.SerializeObject(licenseMachine), Encoding.UTF8, "application/json"),
};

How to call web api with multiple parameter in c# xamarin forms

I know this is a repeated question. I have tried many examples showed on stackoverflow. But the API is still not calling and it shows 404 not found error. I have tried the below examples,
Example 1:
using (var loginData = new MultipartFormDataContent())
{
loginData.Add(new StringContent(JsonConvert.SerializeObject(login.Email)), "emailId");
loginData.Add(new StringContent(JsonConvert.SerializeObject(this.Password)), "password");
var httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var response = await httpClient.PostAsync("http://6cxsfera.ngrok.io/api/users/authenticate", loginData);
if (response.StatusCode == System.Net.HttpStatusCode.OK)
{
Application.Current.MainPage = new AppShell();
}
}
Example 2:
JObject loginData = new JObject();
loginData.Add("emailId", login.Email);
loginData.Add("password", this.Password);
var httpClient = new HttpClient();
var httpContent = new StringContent(loginData.ToString(), Encoding.UTF8, "application/json");
var response = await httpClient.PostAsync("http://6cxsfera.ngrok.io/api/users/authenticate", httpContent);
My API:
[Route("authenticate")]
[HttpPost]
public HttpResponseMessage Login(HttpRequestMessage request, string emailId, string password)
{
}
Please suggest me to pass multiple parameters to web API in c# xamarin forms.

You can generate code by postman. Then check hat you are missing. you can even use same code generated by postman. https://learning.getpostman.com/docs/postman/sending_api_requests/generate_code_snippets/
just install restSharp nuget package.. it will work with postman generated code.

Instead of creating JObject create a class which holds your emailId and password property like below.
public class UserModel
{
public string emailId {get;set;}
public string password {get;set;}
}
now later instantiate UserModel and assign values like below
UserModel user = new UserModel
{
emailId = "emailId",
password = "password"
};
Serialize UserModel like below
string serializedModel = await Task.Run(() => JsonConvert.SerializeObject(user));
var contents = new StringContent(serializedModel);
contents.Headers.ContentType = MediaTypeHeaderValue.Parse("application/json");
Make a Post Request
var response = await httpClient.PostAsync("http://6cxsfera.ngrok.io/api/users/authenticate", contents);
If the above solution doesn't work try changing your Web Api method route like below
Route["api/users/authenticate"]
Hope this will solve your issue... :)

you could try this:
using (var httpclient = new HttpClient())
{
var formcontent = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string,string>("emailId",emailId),
new KeyValuePair<string, string>("password","password")
});
var request = await httpclient .PostAsync("http://6cxsfera.ngrok.io/api/users/authenticate", formcontent);
request.EnsureSuccessStatusCode();
var response = await request.Content.ReadAsStringAsync();
}

How can I get ID Token from custom token via FirebaseAdmin SDK?

How can I get ID Token from custom token?
[Fact]
public void Get_ID_Token_For_Service_Account_Test()
{
using (Stream stream = new FileStream(ServiceAccountJsonKeyFilePath, FileMode.Open, FileAccess.Read))
{
ServiceAccountCredential credential = ServiceAccountCredential.FromServiceAccountData(stream);
FirebaseApp.Create(new AppOptions
{
Credential = GoogleCredential.FromServiceAccountCredential(credential),
ServiceAccountId = ServiceAccountId,
});
var uid = "Some UID";
var additionalClaims = new Dictionary<string, object>
{
{"dmitry", "pavlov"}
};
string customToken = FirebaseAuth.DefaultInstance.CreateCustomTokenAsync(uid, additionalClaims).Result;
string idToken= null; // How to get this?
FirebaseToken token = FirebaseAuth.DefaultInstance.VerifyIdTokenAsync(idToken, CancellationToken.None).Result;
Assert.NotNull(token);
Assert.True(token.Claims.ContainsKey("dmitry"));
}
}
I see samples for some other languages/platforms but not for C# - how to get ID token via current user here - Retrieve ID tokens on clients. But for C# neither UserRecord nor FirebaseAuth provides ID Token. Any pointers are much appreciated.

I have found the way to get the ID token in FirebaseAdmin integration tests - see method SignInWithCustomTokenAsync. The only thing I have to adjust was base URL: according to Firebase Auth REST API documentation it should be
https://identitytoolkit.googleapis.com/v1/accounts:signInWithCustomToken
The API KEY refers to the Web API Key, which can be obtained on the project settings page in your admin console.
So the adjusted code looks like this:
private static async Task<string> SignInWithCustomTokenAsync(string customToken)
{
string apiKey = "..."; // see above where to get it.
var rb = new Google.Apis.Requests.RequestBuilder
{
Method = Google.Apis.Http.HttpConsts.Post,
BaseUri = new Uri($"https://identitytoolkit.googleapis.com/v1/accounts:signInWithCustomToken")
};
rb.AddParameter(RequestParameterType.Query, "key", apiKey);
var request = rb.CreateRequest();
var jsonSerializer = Google.Apis.Json.NewtonsoftJsonSerializer.Instance;
var payload = jsonSerializer.Serialize(new SignInRequest
{
CustomToken = customToken,
ReturnSecureToken = true,
});
request.Content = new StringContent(payload, Encoding.UTF8, "application/json");
using (var client = new HttpClient())
{
var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
var json = await response.Content.ReadAsStringAsync();
var parsed = jsonSerializer.Deserialize<SignInResponse>(json);
return parsed.IdToken;
}
}
