异步加载数据以在 .net core 2.2 中查看

Question

我正在消费 wego api 列出航班。 但我会在每个请求中获得少量数据，所以我想将所有数据异步加载到视图中。.net 核心中是否有任何解决方案

对于数据提取，我使用以下代码。 所以在查看后我不想停止数据获取。因为我只有 100 条记录，我需要查看剩余的数据，这里没有分页

const int numberOfResultsToGet = 100;
var results = new List<SearchResultMv>();
while (results.Count < numberOfResultsToGet)
{
    var response = await GetFlights(flightParam, auth);
    results.AddRange(response.Results);

    // update offset
    flightParam.Offset += response.Results.Count;

    // sleep for 1 second before sending another request
    Thread.Sleep(TimeSpan.FromSeconds(1));
}

    int Parallelism => 5;
    int NumberOfResultsToGet = 100;
           [HttpGet("get")]
    public async Task<IActionResult> GetFlightsAsync()
    {
        var flights = await 
        GetFlightsByPartitionAsync(GetPages(NumberOfResultsToGet));
        return Ok(flights);
    }

    private async Task<List<SearchResult>> GetFlightsByPartitionAsync(IList<int> 
   pages)
    {
        var result = new List<SearchResult>();

        var output = System.Collections.Concurrent.Partitioner
               .Create(pages)
               .GetPartitions(Parallelism)
               .Select(partition => Task.Run(async () =>
               {
                   using (partition)
                   {
                       while (partition.MoveNext())
                       {
                 // Perform your logic here
                           lock (result)
                               result.Add(new SearchResult() { FlightNo = partition.Current });
                       }
                   }
               }));

        await Task.WhenAll(output);
        return result;
    }
    private IList<int> GetPages(int results)
    {
        IList<int> pages = new List<int>();
        for (int iteration = 1; iteration <= results; iteration++)
            pages.Add(iteration);

        return pages;
    }
