POST with IHttpClient not sending header

[Amything 122]

Hey,

I have the code below which if I use with GET it works fine and I get the Authorization header . However if using POST the header does not get delivered. I don't see any hints in the log:
 

2024-12-13 23:41:33.779 Info MyPlugin: Sending POST request to http://192.168.50.205:5016/api/report
2024-12-13 23:41:33.779 Info HttpClient: POST http://192.168.50.205:5016/api/report

I've verified with Postman that my server works as expected. Does anyone have a POST example I could check out or is it a known problem perhaps?
 

private async Task<string> WebRequestAPI(string url, CancellationToken cancellationToken, string method, string postData = null, string apiKey = null)
{
    if (string.IsNullOrEmpty(apiKey))
    {
        logging.Error($"apiKey is null or empty, cannot make request to {url}");
        return null;
    }

    logging.Info($"Sending {method} request to {url}");

    var options = new HttpRequestOptions
    {
        CancellationToken = cancellationToken,
        Url = url,
        TimeoutMs = 20000,
    };

    options.RequestHeaders.Add("Authorization", $"Bearer {apiKey}");
    HttpResponseInfo response;

    try
    {
        if (method.ToUpper() == "POST")
        {
            if (string.IsNullOrEmpty(postData))
            {
                logging.Error($"postData is null or empty, cannot make POST request to {url}");
                return null;
            }

            options.RequestContent = postData.AsMemory();
            options.RequestContentType = "application/json";

            response = await _httpClient.Post(options).ConfigureAwait(false);
            using (var stream = response.Content)
            using (var reader = new StreamReader(stream))
            {
                var result = await reader.ReadToEndAsync().ConfigureAwait(false);
                logging.Info($"Received response: {result}");
                return result;
            }
        }
        else
        {
            using (var stream = await _httpClient.Get(options).ConfigureAwait(false))
            using (var reader = new StreamReader(stream))
            {
                var result = await reader.ReadToEndAsync().ConfigureAwait(false);
                logging.Info($"Received response: {result}");
                return result;
            }
        }
    }
    catch (HttpException ex)
    {
        logging.ErrorException($"Error from {url} using method {method}", ex);
        if (ex.IsTimedOut)
        {
            logging.ErrorException($"Could not connect to host {url}", ex);
        }
        return string.Empty;
    }
}

Forgot to mention that I was testing this on 4.9.0.33 beta.

HI, there has to be something else going on. We have our own usages of this that are doing Post with headers and they are working just fine.

[Amything 122]

Yeah, I'm a bit stumped at the moment. I'll try to make a minimal example and see how it goes.

[Amything 122]

I tried to post it https://httpbin.org/post which just returns the response and I can see the header. So this is on my end somewhere.

If I rename from Authorization to Auth it works. Bunch of people seeing the same issue, it's a server configuration issue. I was just so convinced it was a IHttpClient problem because GET worked and also Postman works. With further testing Postman works only if it's on the same machine. Cheers!

Thanks for following up !
