Problem:
A developer integrating speech-to-text functionality in their .NET backend application via the REST API encountered issues with the query-status and stop-stt endpoints. These endpoints require the Content-Type header, but if omitted, they return the error: “No content-type in header fields.”
However, using the Content-Type header with GET and DELETE requests is unconventional and potentially violates the HTTP protocol since these HTTP verbs typically do not include a request body. Furthermore, the .NET HttpClient class does not natively support setting content for these verbs.
Resolution:
The issue was resolved by utilizing the SendAsync(HttpRequestMessage) method of HttpClient to specify the Content-Type header. This approach bypasses the limitations of GetAsync and DeleteAsync, which do not support setting a request body or content type. Below is the solution that worked:
var request = new HttpRequestMessage
{
Method = HttpMethod.Get,
RequestUri = new Uri("your url"),
Content = new StringContent(
string.Empty,
Encoding.UTF8,
MediaTypeNames.Application.Json),
};
var response = await httpClient.SendAsync(request);
