Sometimes, while calling the https://api.spotify.com/v1/me endpoint, I receive a 502 bad gateway error. This error occurs sporadically.
I would appreciate any help. Thanks!
Code:
PublicProfile profile = null;
var url = "https://api.spotify.com/v1/me";
using (var wc = new WebClient())
{
wc.Headers.Add("Authorization", TokenType + " " + AccessToken);
var response = wc.DownloadString(url);
profile = JsonConvert.DeserializeObject<PublicProfile>(response, settings);
}
I having the same issue. A majority of time when I make this request I get the 502: Bad Gateway response. Occasionally I will get an actual response. I am using Python and rauth library to make this request, this leads me to believe this is an error on Spotify's end and not ours.

I have implemented webhook for revenuecat in .net core C#. But for some reason I am getting 400 badrequest with empty response. I am mostly sure that I am not getting the json response in webook through revenuecat for any of the event occurring.
I have also added endpoint on revenue cat webhook with authentication. I have tried several time and as I have not way to test this on local machine. I need help from revenue cat team to provide some reference doc with sample implementation just to get proper json response. Below is the code snippet that I am using to get json response from the webhook endpoint added in revenuecat.
var webHookSecret = _configuration[Constants.RevenueCatWebHookSecret]; var headerAuthorization = HttpContext.Request.Headers["Authorization"].ToString(); #region Check authorization if (webHookSecret == headerAuthorization) { json = await new StreamReader(HttpContext.Request.Body).ReadToEndAsync(); } else { _logger.Information($"Un-Authorized token access in revenuecat webhook. Returning BadRequest response."); throw new APIException(HttpStatusCode.Unauthorized, new APIError(_configuration, "InternalServerError")); }
I'm trying to read all accounts my user is associated with. The Documentation claims that this should be possible by calling:
GET https://app.vssps.visualstudio.com/_apis/accounts?api-version=5.1
Because the docs are kind of confusing it could be that I have to call
GET https://app.vssps.visualstudio.com/_apis/accounts?ownerId={GUID}&api-version=5.1
instead.
I'm using OAuth-Authentication. In order to get it work I created an ASP.NET Core application. I created an app registration in DevOps and I retrieve an OAuth token with the following scopes without any problem:
vso.auditlog
vso.connected_server
vso.dashboards
vso.entitlements
vso.environment_manage
vso.graph
vso.identity
vso.loadtest
vso.machinegroup_manage
vso.memberentitlementmanagement
vso.profile
vso.project
vso.securefiles_read
vso.security_manage
vso.taskgroups_read
vso.tokenadministration
vso.tokens
vso.variablegroups_read
vso.wiki
According to the docs only vso.profile should be necessary for this request.
However the result I receive is always:
HttpRequestException: Response status code does not indicate success: 401 (TF400813: The user '{AZURE_TENANT_ID}\{MY_MAIL_ADDRESS}' is not authorized to access this resource.).
Other requests are working just fine e.g.:
GET https://dev.azure.com/{organization}/{project}/_apis/build/builds?api-version=5.1
The accounts-request is special because it can be sent without setting the context to a specific organisation or project. I guess this the reason for the different results.
EDIT
After trying ot today using the both URLs mentioned above I now get 400 as the response status code. This is a sample Bearer-Token I got after I decoded it:
{
"nameid": "1340eb0b-cabf-476c-a950-a070c34ca367",
"scp": "vso.profile",

}
Here is some simplified C# code I use:
HttpClient client = _clientFactory.CreateClient("DevOps");
var token = await _authHelper.GetTokenAsync(tokenType);
client.DefaultRequestHeaders.Add("Authorization", $"Bearer { token.AccessToken}");
var uri = "https://app.vssps.visualstudio.com/_apis/accounts?api-version = 5.1";
try
{
var response = await client.GetAsync(uri);
response.EnsureSuccessStatusCode();
var content = await response.Content.ReadAsStringAsync();
return content;
}
catch (Exception ex)
{
// ex.Message = Response status code does not indicate success: 400 (Bad Request).
// ...
throw;
}
Visual Studio 2019, .NET 3.0 preview, Created a blazor application. Trying to get weather data from https://api.weather.gov/gridpoints/ALY/59,14/forecast.
I am using HttpClient in C#. This is getting forbidden (403) response
Tried to add CORS policty
private async Task<IWeatherDotGovForecast> RetrieveForecast()
{
string url = #"https://api.weather.gov/gridpoints/ALY/59,14/forecast";
var response = await _httpClient.GetAsync(url);
if (response != null)
{
var jsonString = await response.Content.ReadAsStringAsync();
return JsonConvert.DeserializeObject<WeatherDotGovForecast>(jsonString);
}
//return await _httpClient.GetJsonAsync<WeatherDotGovForecast>
// ("https://api.weather.gov/gridpoints/ALY/59,14/forecast");
return null;
}
I expected JSON data from https://api.weather.gov/gridpoints/ALY/59,14/forecast
Instead, I am getting Forbidden (403) status code
Your problem is not related to Blazor but weather.gov requires a User-Agent header in any HTTP request.
Applications accessing resources on weather.gov now need to provide a User-Agent header in any HTTP request. Requests without a user agent are automatically blocked. We have implemented this usage policy due to a small number of clients utilizing resources far in excess of what most would consider reasonable.
Use something like this:
var _httpClient = new HttpClient();
string url = #"https://api.weather.gov/gridpoints/ALY/59,14/forecast";
_httpClient.DefaultRequestHeaders.Add("User-Agent", "posterlagerkarte");
var response = await _httpClient.GetAsync(url);
I have been stuck in one issue. I am getting error of "Unable to connect to the remote server. An attempt was made to access a socket in a way forbidden by its access permissions".
After searching on web and taking help of azure support, I came to know that if Web App reaches outbound connection limit of azure web app instance, it refuses connections or kill extra connections. Here is the image of open socket handles
My application calls third party WebAPI and wcf service. I have written code to close connections after making call to APIs. but it doesn't work for me. I did following code to call Web API.
var request = (HttpWebRequest)WebRequest.Create("www.xyz.com");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.KeepAlive = false;
request.Headers.Add("Authorization", "Handshake");
byte[] bodyData;
bodyData = Encoding.UTF8.GetBytes(input_data);
request.ContentLength = bodyData.Length;
request.GetRequestStream().Write(bodyData, 0, bodyData.Length);
request.GetRequestStream().Flush();
request.GetRequestStream().Close();
using (var response = request.GetResponse())
{
using (var reader = new StreamReader(response.GetResponseStream(),
Encoding.UTF8))
{
string output_data = reader.ReadToEnd();
}
response.Close();
}
Could anyone guide me how to get rid on this issue?
I have HttpHandler (abc.ashx), which I make a call to process (Bulk Upload) an excel file. This processing takes a certain amount of time, which is proportionate to the number of rows in the excel.
On top of this I have an Event Handler in Sharepoint which uses a WebClient to make a post service call to this handler using the code below;
NOTE: I generate an identity token using elevated privilege of Sharepoint, and use that token to impersonate to make the service call. net net I make the post service call using the identity of the System Account.
WindowsIdentity identity = null;
// Get an identity token using delegate activity of Elevated Privelleges of Sharepoint
SPHelper.ElevatedActivity(properties.Web.Site.Url, properties.Web.ServerRelativeUrl, web =>
{
identity = WindowsIdentity.GetCurrent();
});
//Impersonates the identity of System Account user, as received in token in the line above
using (identity.Impersonate())
{
// create a web client object which only increases the timeout of the web client call
var webClient = (new CustomWebClient());
webClient.Credentials = CredentialCache.DefaultNetworkCredentials;
webClient.UseDefaultCredentials = true;
//url of the httphandler as deployed in sharepoint, and the parameters that needs to be passed
string handlerUrl =
string.Format(
properties.Web.Url.Trim('/') + "/_layouts/Handlers/abc.ashx?Table=BulkUpload&Region={0}&UserId={1}&BatchId={2}&FileUrl={3}",
region, userValue.User.LoginName, batchId, fileUrl);
}
// execute the web service call using the webclient object
webClient.DownloadString(handlerUrl));
Essentially this code is written in the Event Handler for ItemAdded and ItemUpdated event.
The issue is in the webClient which seems to give an error "system.net.webexception: the remote server returned an error: (401) unauthorized", after precisely 5 mins of processing. Hence if the excel sheet to be processed has rows less than certain number (1700), the processing happens within 5 minutes, and everything runs fine without any error. However if it has more than that, then the processing takes more than 5 minutes, and fails with the error specificed above.
The strange behaviour is it seems like a timeout issue but the error message indicates authorization issue, which does not make sense, as if there was an authorization issue, it shouldnt have worked even when the processing time was less that 5 minutes.
We have tried to find any configuration that times out in 5 minutes, however we could not find any.
Any help or suggestion on this matter is appreciated.
UPDATE: I have now tried to make this work using HttpWebRequest, and have tried a bunch of setting which might cause this timeout/issue. However still getting the same issue, where after 5 minutes of processing I am getting "system.net.webexception: the remote server returned an error: (401) unauthorized". Below is the code I have tried
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(handlerUrl);
httpWebRequest.Credentials = CredentialCache.DefaultCredentials;
httpWebRequest.UseDefaultCredentials = true;
httpWebRequest.Timeout = 600000;
httpWebRequest.ReadWriteTimeout = 600000;
httpWebRequest.ServicePoint.ConnectionLeaseTimeout = 600000;
httpWebRequest.ServicePoint.MaxIdleTime = 600000;
httpWebRequest.ContentType = "application/json; charset=utf-8";
httpWebRequest.ContentLength = 0;
httpWebRequest.Method = WebRequestMethods.Http.Get;
BulkUploadProcessorResponse response = null;
var httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (Stream stream = httpWebResponse.GetResponseStream())
{
using (StreamReader sr = new StreamReader(stream))
{
response =
JsonHelper.JsonDeserialize<BulkUploadProcessorResponse>(sr.ReadToEnd());
}
}
