Использование Publi c API

Question

Fiddler также работает с приведенными ниже деталями в compose

GET https://api.census.gov/data/2014/pep/natstprc?get=STNAME,POP&DATE_=7&for=state:*

Вот мой код, который я пытаюсь, но возвращаю 403

_httpClient.BaseAddress = new Uri("https://api.census.gov/data/2014/pep/natstprc");
_httpClient.Timeout = new TimeSpan(0, 0, 30);
_httpClient.DefaultRequestHeaders.Host = "api.census.gov";
_httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xhtml+xml"));
_httpClient.DefaultRequestHeaders.Add("User-Agent", "Chrome");
_httpClient.DefaultRequestHeaders.Add("Accept-Language", "en-US,en");
_httpClient.DefaultRequestHeaders.Add("Accept-Encoding", "gzip,deflate,br");
_httpClient.DefaultRequestHeaders.Add("Sec-Fetch-Dest", "document");
_httpClient.DefaultRequestHeaders.Add("Sec-Fetch-Mode", "navigate");
_httpClient.DefaultRequestHeaders.Add("Sec-Fetch-Site", "none");
_httpClient.DefaultRequestHeaders.Add("Sec-Fetch-User", "?1");
var res = _httpClient.GetAsync(_httpClient.BaseAddress).Result;

поработайте для меня с приведенным ниже кодом, спасибо за вашу помощь.

var handler = new HttpClientHandler (); handler.DefaultProxyCredentials = CredentialCache.DefaultCredentials;

using (var httpClient = new HttpClient (обработчик)) {httpClient.DefaultRequestHeaders.Add ("User-Agent", "Mozilla / 5.0 (Windows NT 6.1; Win64) ; x64) AppleWebKit / 537.36 (K HTML, как Gecko) Chrome / 58.0.3029.110 Safari / 537.36 "); var response = httpClient.GetStringAsyn c (новый Uri ("https://api.census.gov/data/2014/pep/natstprc?get=STNAME, POP & DATE_ = 7 & for = state: *")). Результат; var Release = JArray.Parse (ответ);

}
