In order to test the Azure DevOp API,
POST https://dev.azure.com/{organization}/{project}/_apis/git/repositories/{repositoryId}/itemsbatch?api-version=6.0
we need to log in first.
HTTP/1.1 203 Non-Authoritative Information
What is the best way to handle authentication in this API testing?
Add tokens in the request headers?
After you get JWT you can use it in the command line like below:
set header Authorization "bearer <TOKEN VALUE>"
You can see this link https://learn.microsoft.com/en-us/aspnet/core/web-api/http-repl/?view=aspnetcore-6.0&tabs=windows#set-http-request-headers
To test the REST API, you need either Testing Tool to drive the API or writing down your own code.
Rest API can be tested with tools like:
Advanced Rest Client
Postman
To write your own code, you could refer to the following sample:
public static async void GetProjects()
{
try
{
var personalaccesstoken = "PAT_FROM_WEBSITE";
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(
new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(
System.Text.ASCIIEncoding.ASCII.GetBytes(
string.Format("{0}:{1}", "", personalaccesstoken))));
using (HttpResponseMessage response = await client.GetAsync(
"https://dev.azure.com/{organization}/_apis/projects"))
{
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseBody);
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}

Just new to ms graph and also to .net.
I'm trying to write a method that deletes a notification subscription. The code itself seems to work. But i need to know how to look up the actual return code from the upstream API instead of just sending back a 204.
Here's the code:
[Route("msgraphnotification/{subscriptionId}")]
[HttpDelete]
[AllowAnonymous]
public async Task<Int> delete(string subscriptionId)
{
try{
GraphServiceClient graphClient = await getAuthToken();
await graphClient.Subscriptions["{subscription-id}"]
.Request()
.DeleteAsync();
return 204; // this is what I want to fix.
}
catch(Exception ex){
Console.Write(ex);
return 404;
}
}
If you really need to know the response code you can send HTTP request with the .Net Microsoft Graph client library.
// Get the request URL for deleting a subscription
var requestUrl = client.Subscriptions["{subscription-id}"].Request().RequestUrl;
// Create the request message.
var hrm = new HttpRequestMessage(HttpMethod.Delete, requestUrl);
// Authenticate HttpRequestMessage
await client.AuthenticationProvider.AuthenticateRequestAsync(hrm);
// Send the request and get the response.
var response = await client.HttpProvider.SendAsync(hrm);
// Get the status code.
if (!response.IsSuccessStatusCode)
{
throw new ServiceException(
new Error
{
Code = response.StatusCode.ToString(),
Message = await response.Content.ReadAsStringAsync()
});
}
else
{
var statusCode = (int)response.StatusCode;
}

Please let me know if this is not possible...but in an effort to refactor my personal API I decided to start calling the Twitch endpoints through my API so data can be combined. To do this I direct the user to the auth page and get a bearer token back. I then pass that token to my API in the header. For some reason I get a 401 if I try to use that token at all from my API. I have no idea why as I can't view a reason in the response. The token works from postman.
Here is an example of a request I make in my API:
public async Task<bool> ValidateToken()
{
var response = await client.GetAsync("https://id.twitch.tv/oauth2/validate");
return response.StatusCode == HttpStatusCode.OK;
}
The HttpClient is created as follows before the validation method is called:
public TwitchService(IHeaderDictionary headers)
{
StringValues token;
StringValues clientId;
var hasToken = headers.TryGetValue("Authorization", out token);
var hasClientId = headers.TryGetValue("Client-id", out clientId);
client = new HttpClient();
client.DefaultRequestHeaders.Add("Accept", "application/json");
if (hasToken)
{
var authToken = token.ToString().Replace("Bearer", "");
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", authToken);
}
if (hasClientId)
{
client.DefaultRequestHeaders.Add("Client-ID", clientId.ToString());
}
}
It turns out that the auth header is removed by the HttpClient and this is by design. The following link gives a good explanation about it: Authorization header is lost on redirect
While trying to create a Test Suite using TFS 2017 REST API, I am getting the error:
System.Net.Http.HttpRequestException - Response status code does not
indicate success: 500 (Internal Server Error)
Code I tried:
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
string base64StringPat = Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", "", Configs.Pat)));
AuthenticationHeaderValue authHeader = new AuthenticationHeaderValue("Basic", base64StringPat);
client.DefaultRequestHeaders.Authorization = authHeader;
string url = "http://vmctp-tl-mtm:8080/tfs/DefaultCollection/SgkProject/_apis/test/Plans/7/Suites/8?api-version=1.0";
var content = new StringContent("{\"suiteType\":\"StaticTestSuite\",\"name\":\"Module1\"}", Encoding.UTF8, "application/json");
using (HttpResponseMessage response = client.PostAsync(url, content).Result)
{
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseBody);
}
}
I have used this documentation from Microsoft to call the API: Create a test suite
Please guide me in fixing the issue.
HTTP code 500 means that this is an error on your server. The server threw an exception when trying to process this POST request.
So, this error has nothing to do with HttpClient. Just check your server first and see what causes the exception.
A possibility is that the specified content type is not expected by the server. POST a StringContent will set the content type to text/plain. You might find the server doesn't like that. In this case just try to find out what media type the server is expecting and set the Headers.ContentType of the StringContent instance.
Whatever, I can create the suite by below sample, you can have a try for that:
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;
namespace CreateTestSuite
{
class Program
{
public static void Main()
{
Task t = CreateTestSuite();
Task.WaitAll(new Task[] { t });
}
private static async Task CreateTestSuite()
{
try
{
var username = "username";
var password = "password";
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(
new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(
System.Text.ASCIIEncoding.ASCII.GetBytes(
string.Format("{0}:{1}", username, password))));
string url = "http://server:8080/tfs/DefaultCollection/LCScrum/_apis/test/plans/212/suites/408?api-version=1.0";
var content = new StringContent("{\"suiteType\":\"StaticTestSuite\",\"name\":\"Module3\"}", Encoding.UTF8, "application/json");
using (HttpResponseMessage response = client.PostAsync(url, content).Result)
{
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseBody);
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}
}
}
In need of some help accessing an external Web API passing along credentials in order to access the methods available. I have included the code below that i use in order to attempt to access the Web API. However, i receive the following error every time i attempt to access it:
"The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."
What am i missing or what am i doing wrong? I have been circling around this for a couple days and have tried a couple different techniques but continue to get the same error. Here is one technique that i used.
private static async Task<string> GetAPIToken(string userName, string password, string apiBaseUri)
{
try
{
using (var client = new HttpClient())
{
//setup client
client.BaseAddress = new Uri(apiBaseUri);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//setup login data
var formContent = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string,string>("username",userName),
new KeyValuePair<string,string>("password",password),
});
//send request
HttpResponseMessage responseMessage = await client.PostAsync("Token", formContent);
//get access token from response body
var responseJson = await responseMessage.Content.ReadAsStringAsync();
var jobject = JObject.Parse(responseJson);
return jobject.GetValue("access_token").ToString();
}
}
catch (Exception ex)
{
return null;
}
}
Any help would be greatly appreciated.
Thanks
There is a little bit of a difference when using HTTPS vs HTTP. This question should give you the information you need to fix your problem.
Make Https call using HttpClient
Please let me know the procedure for communication between window store app and MVC such that data can be passed from MVC to Store app and vice versa.
Did you mean call to a web API?
You can use System.Net.Http.HttpClient to send http requests & receive responses.
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:9000/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
// New code:
HttpResponseMessage response = await client.GetAsync("api/products/1");
if (response.IsSuccessStatusCode)
{
Product product = await response.Content.ReadAsAsync>Product>();
Console.WriteLine("{0}\t${1}\t{2}", product.Name, product.Price, product.Category);
}
}
A detailed guide available Here. It shows how you can use WebApi with Windows store app.
The recommended way to connect to a web service is to use the Windows.Web.Http.HttpClient (which supersedes System.Net.Http.HttpClient). This can be used to send any normal HTTP request (PUT, POST, GET, etc.)
using Windows.Web.Http;
using (HttpClient hc = new HttpClient())
{
Uri uri = new Uri("https://api.stackexchange.com/2.2/questions/27796508?order=desc&sort=activity&site=stackoverflow");
try
{
string json = await hc.GetStringAsync(uri);
}
catch (Exception ex)
{
// Handle network exceptions
}
}
See How to connect to an HTTP server using Windows.Web.Http on MSDN and the HttpClient sample for more details.
