無法在Java中獲取Set-Cookie屬性

Question

我有一個Java方法，應該獲取Set-Cookie屬性，以便隨后登錄到網頁。 但是conn.getHeaderFields（）。get（“ Set-Cookie”）不會返回任何內容。 有什么建議嗎？

  private String GetPageContent(String url) throws Exception {

URL obj = new URL(url);
conn = (HttpsURLConnection) obj.openConnection();

// default is GET
conn.setRequestMethod("GET");

conn.setUseCaches(false);

// act like a browser
conn.setRequestProperty("User-Agent", USER_AGENT);
conn.setRequestProperty("Accept",
        "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
conn.setRequestProperty("Accept-Language", "s-CZ,cs;q=0.8,en;q=0.6");
if (cookies != null) {
    for (String cookie : this.cookies) {
        conn.addRequestProperty("Cookie", cookie.split(";", 1)[0]);
    }
}
int responseCode = conn.getResponseCode();
System.out.println("\nSending 'GET' request to URL : " + url);
System.out.println("Response Code : " + responseCode);

BufferedReader in = 
        new BufferedReader(new InputStreamReader(conn.getInputStream(),"UTF-8"));
String inputLine;
StringBuffer response = new StringBuffer();

while ((inputLine = in.readLine()) != null) {
    response.append(inputLine);
}

in.close();

// Get the response cookies

System.out.println(conn.getHeaderFields().get("Set-Cookie")); //print for testing
setCookies(conn.getHeaderFields().get("Set-Cookie"));

return response.toString();

最新的Java版本已“修復” URLConnection以隱藏標記為HttpOnly的cookie，但我認為沒有禁用它的設置。 我建議從Apache HttpComponents使用HttpClient 。
