I try to send POST request with parameters with this code:
var uri = new Uri("http://127.0.0.1:81/login/login");
var client = new DefaultHttpClient();
var par = new BasicHttpParams();
par.SetParameter("username", "admin")
par.SetParameter("password", "****");
var request = new HttpPost(uri);
request.SetParams(par);
var response = client.Execute(request);
But ASP.NET MVC server do not receive this parameters in action method.
Adapt to this snippet: http://www.androidsnippets.com/executing-a-http-post-request-with-httpclient
var httpclient = new DefaultHttpClient();
var nameValuePairs = new ArrayList<INameValuePair>(2);
nameValuePairs.Add(new BasicNameValuePair("username", "admin"));
nameValuePairs.Add(new BasicNameValuePair("password", "***"));
var ent = new UrlEncodedFormEntity(nameValuePairs);
httppost.SetEntity(ent);
var response = httpclient.Execute(httppost);

I am trying to call an Azure API (Text Analytics API) from a C# console application with a HttpRequest and I do not want to use any DLLs or await
but using the below snippet I am receiving "Bad Request". Can someone help me where it is going wrong.
public static void ProcessText()
{
string apiKey = "KEY FROM AZURE";
var client = new HttpClient();
var queryString = HttpUtility.ParseQueryString(string.Empty);
// Request headers
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", apiKey);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var requestUri = "https://eastus.api.cognitive.microsoft.com/text/analytics/v2.0/sentiment?" + queryString;
//HttpResponseMessage response;
// Request body
byte[] byteData = Encoding.UTF8.GetBytes("I really love Azure. It is the best cloud platform");
using (var content = new ByteArrayContent(byteData))
{
//content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
var response = client.PostAsync(requestUri, content).Result;
Console.WriteLine(response);
Console.ReadLine();
}
}
string apiKey = "<<Key from Azure>>";
var client = new HttpClient();
var queryString = HttpUtility.ParseQueryString(string.Empty);
// Request headers
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", apiKey);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var requestUri = "https://**eastus**.api.cognitive.microsoft.com/text/analytics/v2.0/sentiment?" + queryString;
//HttpResponseMessage response;
var body = new
{
documents = new[]
{
new
{
ID="1", text="I really love Azure. It is the best cloud platform"
}
}
};
string json = JsonConvert.SerializeObject(body);
byte[] byteData = Encoding.UTF8.GetBytes(json);
dynamic item = null;
using (var con = new ByteArrayContent(byteData))
{
//content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
var response = client.PostAsync(requestUri, con).Result;
if (response.StatusCode == HttpStatusCode.OK)
{
string res = string.Empty;
using (HttpContent content = response.Content)
{
Task<string> result = content.ReadAsStringAsync();
res = result.Result;
}
JavaScriptSerializer serializer = new JavaScriptSerializer();
item = serializer.Deserialize<object>(res);
}

Hi All, I could able to get the API output using the above approach
My unit test is-
String xmlText = File.ReadAllText(#"C:\PrashantWorkspace\Weather.xml");
var mockFactory = new Mock<IHttpClientFactory>();
var mockHttpMessageHandler = new Mock<HttpMessageHandler>();
mockHttpMessageHandler.Protected()
.Setup<Task<HttpResponseMessage>>("SendAsync", ItExpr.IsAny<HttpRequestMessage>(), ItExpr.IsAny<CancellationToken>())
.ReturnsAsync(new HttpResponseMessage
{
StatusCode = HttpStatusCode.OK,
Content = new StringContent(xmlText, Encoding.UTF8, "application/xml"),
});
var client = new HttpClient(mockHttpMessageHandler.Object);
mockFactory.Setup(_ => _.CreateClient(It.IsAny<string>())).Returns(client);
WeatherController wController = new WeatherController(_logger.Object, _configuration.Object, mockFactory.Object);
var result = await wController.Get("1", "2", false);
Assert.IsType<OkObjectResult>(result);
How can I pass another xml that will be used by 2nd api call in my controller?
If you mean that you have another endpoint (and not the second call to the same endpoint), then you can pass a predicate that will match on the RequestUri of the HttpRequestMessage:
_httpMessageHandlerMock = new Mock<HttpMessageHandler>();
var booksResponse = new HttpResponseMessage
{
StatusCode = HttpStatusCode.OK,
Content = new StringContent(
#"<?xml version=""1.0"" encoding=""utf-8""?> ")
};
_httpMessageHandlerMock
.Protected()
.Setup<Task<HttpResponseMessage>>(
"SendAsync",
ItExpr.Is<HttpRequestMessage>(x =>
x.RequestUri != null && x.RequestUri.ToString().Contains("books")),
ItExpr.IsAny<CancellationToken>())
.ReturnsAsync(booksResponse);
var authorsResponse = new HttpResponseMessage
{
StatusCode = HttpStatusCode.OK,
Content = new StringContent(
#"<?xml version=""1.0"" encoding=""utf-8""?> ")
};
_httpMessageHandlerMock
.Protected()
.Setup<Task<HttpResponseMessage>>(
"SendAsync",
ItExpr.Is<HttpRequestMessage>(x =>
x.RequestUri != null && x.RequestUri.ToString().Contains("authors")),
ItExpr.IsAny<CancellationToken>())
.ReturnsAsync(authorsResponse);
_client = new HttpClient(_httpMessageHandlerMock.Object) {BaseAddress = new Uri("http://tempuri")};
I have tried the method outlined in the Microsoft docs
which involves creating an app in Active Directory and then having code something very similar to:
var authContextUrl = "https://login.windows.net/common/oauth2/authorize";
var authenticationContext = new AuthenticationContext(authContextUrl);
var redirectUri = "https://dev.powerbi.com/Apps/SignInRedirect";
var pp = new PlatformParameters(PromptBehavior.Auto);
var result = authenticationContext.AcquireTokenAsync(PowerBiApiResource, clientId, new Uri(redirectUri), pp).GetAwaiter().GetResult();
if (result == null)
{
throw new InvalidOperationException("Failed to obtain the PowerBI API token");
}
var token = result.AccessToken;
return token;
I got this code working but it always insisted on prompting for a username and password, which is a problem for a function app.
I have also tried the approach in the silent function specified here
https://community.powerbi.com/t5/Developer/Data-Refresh-by-using-API-Need-Steps/m-p/209371#M6614
static string getAccessTokenSilently()
{
HttpWebRequest request = System.Net.HttpWebRequest.CreateHttp("https://login.windows.net/common/oauth2/token");
//POST web request to create a datasource.
request.KeepAlive = true;
request.Method = "POST";
request.ContentLength = 0;
request.ContentType = "application/x-www-form-urlencoded";
//Add token to the request header
request.Headers.Add("Authorization", String.Format("Bearer {0}", token));
NameValueCollection parsedQueryString = HttpUtility.ParseQueryString(String.Empty);
parsedQueryString.Add("client_id", clientID);
parsedQueryString.Add("grant_type", "password");
parsedQueryString.Add("resource", resourceUri);
parsedQueryString.Add("username", username);
parsedQueryString.Add("password", password);
string postdata = parsedQueryString.ToString();
//POST web request
byte[] dataByteArray = System.Text.Encoding.ASCII.GetBytes(postdata); ;
request.ContentLength = dataByteArray.Length;
//Write JSON byte[] into a Stream
using (Stream writer = request.GetRequestStream())
{
writer.Write(dataByteArray, 0, dataByteArray.Length);
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
dynamic responseJson = JsonConvert.DeserializeObject<dynamic>(responseString);
return responseJson["access_token"];
}
}
This code doesn't work.
Also this has issues, although I haven't tried it:
https://learn.microsoft.com/en-us/power-bi/developer/get-azuread-access-token
There doesn't appear to be anything up to date available that works that explains how to do this. Does anyone know how?
This is the best I've got so far. I have to create the application in AD using https://dev.powerbi.com/apps and then login using a powerbi pro userid and password, using the following code:
public static string GetPowerBiAccessToken(string tenantId, string clientId, string userId, string password)
{
var url = $"https://login.windows.net/{tenantId}/oauth2/token";
var request = (HttpWebRequest)WebRequest.Create(url);
request.KeepAlive = true;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
var dataToPost = new Dictionary<string,string>
{
{"client_id", clientId},
{"grant_type", "password"},
{"resource", PowerBiApiResource},
{"username", userId},
{"password", password},
{"redirect_uri", "https://dev.powerbi.com/Apps/SignInRedirect" }
};
var postData = string.Empty;
foreach (var item in dataToPost)
{
if (!string.IsNullOrEmpty(postData))
postData += "&";
postData += $"{item.Key}={item.Value}";
}
var dataByteArray = System.Text.Encoding.ASCII.GetBytes(postData);
request.ContentLength = dataByteArray.Length;
using (var writer = request.GetRequestStream())
{
writer.Write(dataByteArray, 0, dataByteArray.Length);
}
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
var responseJson = JsonConvert.DeserializeObject<dynamic>(responseString);
return responseJson["access_token"];
}
(P.S. I appreciate the request part of this code could be much better but having spent over 2 days trying to work this out, I'm just glad to have something that is working right now. Also the redirectUrl matches the one in my app, I'm not sure if its essential or not).
In the event of errors, I used Fiddler 4 to tell me exactly what the error was rather than just getting 400 or 401 in the app.
Im using Asp.net Core, for calling an asmx service which has 4 methods and i want to call one of them by the name: Verify method, i do this steps:
1-Create realted SOAP:
private XmlDocument CreateSoapEnvelope(PayVM payModel)
{
XmlDocument soapEnvelop = new XmlDocument();
string requiredXML = string.Format(#"<SOAP-ENV:Envelope xmlns:SOAP-ENV=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/1999/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/1999/XMLSchema""><SOAP-ENV:Body><verifyTransaction xmlns=""http://tempuri.org/""> <String_1 xsi:type=""xsd:string"">{0}</String_1><String_2 xsi:type=""xsd:string"">{1}</String_2></verifyTransaction></SOAP-ENV:Body></SOAP-ENV:Envelope>", payModel.ReNO, payModel.MID);
soapEnvelop.LoadXml(requiredXML);
return soapEnvelop;
}
2-create the HttpClient and send my request:
XmlDocument soapRequest = CreateSoapEnvelope(iPGVerifyResultModel);
using (var client = new HttpClient())
{
var request = new HttpRequestMessage()
{
RequestUri = new Uri("relatedUri/ServiceName.asmx"),
Method = HttpMethod.Post
};
request.Content = new StringContent(soapRequest.ToString(), Encoding.UTF8, "text/xml");
request.Headers.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("text/xml"));
request.Content.Headers.ContentType = new MediaTypeHeaderValue("text/xml");
request.Headers.Add("SOAPAction", "Verify"); //I want to call this method
HttpResponseMessage response = client.SendAsync(request).Result;
if (!response.IsSuccessStatusCode)
{
throw new Exception();
}
Task<Stream> streamTask = response.Content.ReadAsStreamAsync();
Stream stream = streamTask.Result;
var sr = new StreamReader(stream);
var soapResponse = XDocument.Load(sr);
//do some other stuff...
}
but i didn't result, i try uses service by same parameters with Soap UI and the service work properly, but in my way i got StatusCode: 400 what is the problem?
