HttpClient响应返回加扰数据

Question

我正在尝试使用HttpClient从该URL获得正确的JSON响应。当我在Chrome中查看URL时，数据的格式是正确的JSON。当我使用HttpClient时，我会得到一堆看起来像字节之类的垃圾数据。我不知道如何把它解码成字符串。请告知。

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;
}

Answer 1

数据返回时使用gzip进行压缩。通过在实例化HttpClient:时启用此属性，您可以让HttpClient自动解压缩此数据

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

Answer 2

我认为您必须从请求头中删除Brotli压缩。Brotli(br(未被.Net.开箱即用解码

也就是说，改变：

httpClient.DefaultRequestHeaders.AcceptEncoding.ParseAdd("gzip, deflate, br");

至

httpClient.DefaultRequestHeaders.AcceptEncoding.ParseAdd("gzip, deflate");
