Controller calls web api, how to handle http error codes returned from API

I think you can log the time, url, status code, response content and other info can help you. A Example From My Project

private static async Task<T> HandleHttpResponse<T>(HttpResponseMessage response)
{
    if (response.IsSuccessStatusCode)
    {
        var result = await response.Content.ReadAsStringAsync();
        return JsonHelper.ToObject<T>(HandleHttpResult(result));
    }
    else
    {
        var result = await response.Content.ReadAsStringAsync();
        LogHelper.WriteLog($"请求{response.RequestMessage.RequestUri}错误，错误描述：{response.StatusCode}，错误码：{response.StatusCode.ToInt32()}，错误内容：{result}", $"{nameof(RemoteServerHelper)}_{nameof(HandleHttpResponse)}", true);
    }
    return default;
}
