我正在編寫應(yīng)用程序.NET，我需要從一些 api 獲取數(shù)據(jù)。我嘗試使用不同的閱讀方法，例如ReadAsStringAsync()，我嘗試將它們轉(zhuǎn)換為UTF-8，我設(shè)置 mediaType text/plain ，我嘗試轉(zhuǎn)換為JSON，但在解析過(guò)程中引發(fā)了錯(cuò)誤。HttpClient client = new HttpClient();client.DefaultRequestHeaders.Accept.Clear();byte[] responded;HttpResponseMessage response = await client.GetAsync(path);response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");if (response.IsSuccessStatusCode){ response.Content.ReadAsByteArrayAsync().Wait(); responded = response.Content.ReadAsByteArrayAsync().Result; var responseString = Encoding.UTF8.GetString(responded, 0, responded.Length); Console.WriteLine("\n " +responseString);}我得到回應(yīng)：?0E?%?}S??WDJpq?%)X??}???s????A???BK?X?}?k但這不是我所期望的：{"items:[{"has_synonyms":true,"is_moderator_only":false,"is_required":false,"count":9452,"name":"tags"}],"has_more":false,"quota_max":300,"quota_remaining":296}

我沒(méi)有意識(shí)到，該響應(yīng)是 gzip 格式。我做了更改：
Stream responded;
HttpResponseMessage response = await client.GetAsync(new Uri(path));
if (response.IsSuccessStatusCode)
{
response.Content.ReadAsStringAsync().Wait();
responded = response.Content.ReadAsStreamAsync().Result;
Stream decompressed = new GZipStream(responded, CompressionMode.Decompress);
StreamReader objReader = new StreamReader(decompressed, Encoding.UTF8);
string sLine;
sLine = objReader.ReadToEnd();
}
并且它工作正常。

我發(fā)現(xiàn)缺少請(qǐng)求接受標(biāo)頭的問(wèn)題！將接受標(biāo)頭設(shè)置為收到的響應(yīng)是行不通的。嘗試下面的代碼。
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeHeaderValue("application/json"));
byte[] responded;
HttpResponseMessage response = await client.GetAsync(path);
if (response.IsSuccessStatusCode)
{
response.Content.ReadAsByteArrayAsync().Wait();
responded = response.Content.ReadAsByteArrayAsync().Result;
var responseString = Encoding.UTF8.GetString(responded, 0, responded.Length);
Console.WriteLine("\n " +responseString);
}
