I have been trying to make a HTTP POST request from plugin without lucky.
I have the same code working fine in my console appication however in plugin I get the following error: "One or more erros occured". I tried to run it asynchronously but it did not work as well.
I really appreciate any idea, thank you!
var client = new HttpClient();
var queryString = HttpUtility.ParseQueryString(string.Empty);
// Request headers
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "KEY");
// Request parameters
queryString["chave"] = "key2";
queryString["codigo_obra"] = codigoObra;
queryString["codigo_bloco"] = codigoBloco;
queryString["codigo_unidade"] = codigoUnidade;
queryString["codigo_planta"] = codigoPlanta;
var uri = "http://test?" + queryString;
HttpResponseMessage response;
// Request body
byte[] byteData = Encoding.UTF8.GetBytes("");
using (var content = new ByteArrayContent(byteData))
{
content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
//This line gives me the error.
response = client.PostAsync(uri, content).Result;
}

I am having the following problem and an extensive search online didn't provide any good results.
When trying to access my Azure Data Explorer Database and querying using the Kusto.Data SDK in an Azure Function, it yields the following error:
Kusto client failed to send a request to the service: 'An unknown, invalid, or unsupported option or level was specified in a getsockopt or setsockopt call.'
However, running the Function on my local machine, everything works fine.
Edit: The function excepts at using (var reader = await queryProvider.ExecuteQueryAsync(Database, query, clientRequestProperties))
EDIT2 - SOLUTION:
You can downgrade the NuGet Kusto.Data Package to Version 9.4.1, this solves the problem and doesn't throw any error anymore. If you still encounter difficulties, you can try to directly access the ADX database via http requests:
const string tenantId = "<tenantId>";
const string client_id = "<clientId>";
const string client_secret = "<client_secret>";
const string Cluster = "<cluster_adress";
const string Database = "<database_name>";
var authUrl = "https://login.microsoftonline.com/<tenantId>/oauth2/token";
var param = new Dictionary<string, string>
{
{"client_id",client_id},
{"grant_type","client_credentials"},
{"client_secret",client_secret},
{"resource","https://help.kusto.windows.net"}
};
var data = new FormUrlEncodedContent(param);
using var authClient = new HttpClient();
var response = await authClient.PostAsync(authUrl, data);
string result = response.Content.ReadAsStringAsync().Result;
//parse result
var resultJson = System.Text.Json.JsonDocument.Parse(result);
//retrieve access token
var accessToken = resultJson.RootElement.GetProperty("access_token");
//-----------------------------------------------------------------------------------------------
var dataXUrl = Cluster + "/v1/rest/query";
var database = Database;
var dataXQuery = "sample_table| where Time > ago(2min)";
var body = new Dictionary<string, string>
{
{"db",database},
{"csl",dataXQuery}
};
using var dataXClient = new HttpClient();
dataXClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken.ToString());
dataXClient.DefaultRequestHeaders.Add("Accept", "application/json");
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, dataXUrl);
request.Content = new StringContent(JsonConvert.SerializeObject(body), Encoding.UTF8, "application/json");
var table = await dataXClient.SendAsync(request);
//pretty print
var obj = JsonConvert.DeserializeObject(table.Content.ReadAsStringAsync());
var tableJSON = JsonConvert.SerializeObject(obj, Formatting.Indented);
log.LogInformation("\n\n" + tableJSON);
I am having the same issue on a continuous webjob on an Azure App Service. The Kusto nuget version I am using is 10.1.0
Downgrading to nuget 9.4.1 solved the problem immediately.
FYI - This only seems to affect 10.1.0. The earlier 10.x.x versions should work.
The ADX team believes they will have this fixed in the next nuget version.
I am creating one webjob which needs to send mail of status of webjobs. I am using webjob API aka "https://xyz.scm.ase-03.com/api/triggeredwebjobs" to get the webjobs details. I am getting the response from my local httpclient call but while deploying it as a webjob on azure then I am getting null response. Here is my code:
var result = string.Empty;
var url = "https://domain.dev.xyz.com/api/";
var baseURL = "triggeredwebjobs";
string userPswd = "username " + ":" + "password"; // getting username and password from publish profile.
userPswd = Convert.ToBase64String(Encoding.Default.GetBytes(userPswd));
using (var client = new HttpClient())
{
client.BaseAddress = new Uri(url);
client.Timeout = TimeSpan.FromMinutes(30);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",userPswd );
var response = new HttpResponseMessage();
response = client.GetAsync(baseURL).Result; // Here I am getting null value.
result = response.IsSuccessStatusCode ? (response.Content.ReadAsStringAsync().Result) : response.IsSuccessStatusCode.ToString();
}
I am in doubt that calling self webjobs api url maybe not working so I deployed it to another app service but no luck.
Can anyone let me know where is the issue may be?
Thanks in advance.
I'm using the client and I need to call a service using authsecret parameter.
If I ad this param to the base url it give me a serialization error.
String baseUrl = AppConfig.GetAppApiUrl();
var client = new JsonServiceClient(baseUrl.AddQueryParam("authsecret","secretz123!"));
var c = client.Send(new ComuneRequest { Id = "A001" });
Using Fiddler I discovered that the request that the client generate is incorrect:
POST
http://192.168.0.63:820/?authsecret=secretz123%21/json/reply/ComuneRequest
So, what I have to do to make the client create a request in a correct format?
It needs to be sent as a Request Parameter (i.e. QueryString or FormData) which you can do using HTTP Utils with:
var url = baseUrl.CombineWith(requestDto.ToUrl()).AddQueryParam("authsecret", secret);
var res = url.GetJsonFromUrl().FromJson<MyResponse>();
Otherwise since AuthSecret is not a property on your Request DTO you wont be able to send it as a Request Parameter in the Request Body, but you should be able to send the param in the Request Headers with:
var client = new JsonServiceClient(baseUrl) {
RequestFilter = req => req.Headers[HttpHeaders.XParamOverridePrefix+"authsecret"] = secret
};
I have the following code sample with which I'm trying to authenticate an Azure active directory user within a Xamarin forms app
The URL (I've removed the actual client ID) works fine in a browser but fails when trying to send the http request
The error message says 'the response type must include client_id'
string URL = "https://login.microsoftonline.com/common/oauth2/v2.0/authorize?"
+ "client_id=xxxx-xxxxx-xxxxx-xxxxx-xxx"
+ "&response_type=code"
+ "&redirect_uri=https://login.microsoftonline.com/common/oauth2/nativeclient"
+ "&response_mode=query"
+ "&scope=openid%20offline_access%20https%3A%2F%2Fgraph.microsoft.com%2Fmail.read"
+ "&state=12345";
var webRequest = System.Net.WebRequest.Create(URL) as HttpWebRequest;
System.Console.WriteLine(URL);
if (webRequest != null)
{
webRequest.Method = "POST";
webRequest.ServicePoint.Expect100Continue = false;
webRequest.Timeout = 20000;
webRequest.ContentType = "text/html";
//POST the data.
using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
{
requestWriter.Write(postData);
}
}
HttpWebResponse resp = (HttpWebResponse)webRequest.GetResponse();
Stream resStream = resp.GetResponseStream();
StreamReader reader = new StreamReader(resStream);
ret = reader.ReadToEnd();
You put parameters in the URL, so you need to use GET method, instead of POST (like your browser does when you paste the URL in its address bar).
So, replace:
webRequest.Method = "POST";
by:
webRequest.Method = "GET";
and remove:
//POST the data.
using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
{
requestWriter.Write(postData);
}
I can't use the ServiceStack Client libraries and I've chosen to use the HttpClient PCL library instead. I can do all my Rest calls (and other json calls) without a problem, but I'm now stucked with uploading files.
A snippet of what I am trying to do:
var message = new HttpRequestMessage(restRequest.Method, restRequest.GetResourceUri(BaseUrl));
var content = new MultipartFormDataContent();
foreach (var file in files)
{
byte[] data;
bool success = CxFileStorage.TryReadBinaryFile(file, out data);
if (success)
{
var byteContent = new ByteArrayContent(data);
byteContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = System.IO.Path.GetFileName(file) ,
};
content.Add(byteContent);
}
}
message.Content = content;
Problem is now that I get a null reference exception (status 500) when posting. I doesn't get into the service. I see the call in the filterrequest, but that's it.
So I'm wondering what I do wrong and how I can pinpoint what is going wrong. How can I catch the correct error on the ServiceStack layer?
