HttpClient 响应返回乱码数据

Question

我正在尝试使用 HttpClient 从此 URL 获取正确的 JSON 响应。当我在 Chrome 中查看 URL 时，数据是正确格式的 JSON。当我使用 HttpClient 时，我收到一堆看起来像字节或类似内容的垃圾数据。我不知道如何将其解码为字符串。请指教。

string url = "https://api.nasdaq.com/api/calendar/earnings?date=2010-07-30";

string calendar = await DownloadFile(new string[] { url });

private static readonly HttpClient httpClient = new HttpClient();

        public static async Task<string> DownloadFile(string[] args)
        {
            string url = args[0];

            httpClient.DefaultRequestHeaders.AcceptEncoding.ParseAdd("gzip, deflate, br");
            httpClient.DefaultRequestHeaders.Connection.ParseAdd("keep-alive");

            string text = await httpClient.GetStringAsync(url);
            
            return text;

        }

数据通过 gzip 压缩返回。您可以HttpClient通过在实例化您的时启用此属性来自动解压缩此数据HttpClient：

    private static readonly HttpClient httpClient = new HttpClient(new HttpClientHandler
    {
        AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
    });
