我被困在這個問題上好幾天了，我的眼睛開始因嘗試不同組合的時間而受到傷害，但沒有成功。事情是，我正在製作一個應用程序，它必須從互聯網上獲取數據，解析並顯示給用戶。我已經嘗試了幾種方法來實現這一點，並且使用JSOUP非常有用，特別是解析數據並將結果從數據中提取出來。將Cookie傳遞給GET請求的問題（POST後）
但是，有一個問題我無法解決。我嘗試過使用常規HTTPClient和JSOUP，但是我無法成功獲取所需的數據。這裏是我的代碼（JSOUP版）：
public void bht_ht(Context c, int pozivni, int broj) throws IOException {
//this is the first connection, to get the cookies (I have tried the version without this method separate, but it's the same
Connection.Response resCookie = Jsoup.connect("http://www.bhtelecom.ba/imenik_telefon.html")
.method(Method.GET)
.execute();
String sessionId = resCookie.cookie("PHPSESSID");
String fetypo = resCookie.cookie("fe_typo_user");
//these two above are the cookies
//the POST request, with the data asked
Connection.Response res = Jsoup.connect("http://www.bhtelecom.ba/imenik_telefon.html?a=search")
.data("di", some_data)
.data("br", some_data)
.data("btnSearch","Tra%C5%BEi")
.cookie("PHPSESSID", sessionId)
.cookie("fe_typo_user", fetypo)
.method(Method.POST)
.execute();
Document dok = res.parse();
//So, here is the GET request for the site which contains the results, and this site is redirected to with HTTP 302 response after the POSt result
Document doc = Jsoup.connect("http://www.bhtelecom.ba/index.php?id=3226&")
.cookie("PHPSESSID", sessionId)
.cookie("fe_typo_user", fetypo)
.referrer("http://www.bhtelecom.ba/imenik_telefon.html")
.get();
Document doc = res2.parse();
Element elemenat = doc.select("div.boxtexter").get(0);
String ime = elemenat.text();
}
所以，最終的結果將是其中包含返回數據的字符串。但是，無論我嘗試什麼，我都會看到「空白」頁面，它是解析的文本，並且我模擬了瀏覽器請求的所有內容。
這裏是POST和GET瀏覽器捕獲的原始標題： （後）

在此GET，（它的響應），數據I需要位於，但是參數，cookie或我嘗試的所有內容的任意組合，我無法讓它「認爲」我發佈了POST並且現在想要這些數據。
這裏是我的代碼沒有JSOUP解析器的版本，但我無法讓它工作，雖然當我檢查這些cookie時，它們都OK，POST和GET也是如此，但沒有成功。
DefaultHttpClient client = new DefaultHttpClient();
String postURL = "http://www.bhtelecom.ba/imenik_telefon.html?a=search";
HttpPost post = new HttpPost(postURL);
post.getParams().setParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, Boolean.FALSE);
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("di", "035"));
params.add(new BasicNameValuePair("br", "819443"));
params.add(new BasicNameValuePair("btnSearch","Tra%C5%BEi"));
UrlEncodedFormEntity ent = new UrlEncodedFormEntity(params,HTTP.UTF_8);
post.setEntity(ent);
HttpResponse responsePOST = client.execute(post);
HttpEntity resEntity = responsePOST.getEntity();
if (resEntity != null) {
//todo
}
//checking for cookies, they are OK
List<Cookie> cookies = client.getCookieStore().getCookies();
if (cookies.isEmpty()) {
Log.d(TAG, "no cookies");
} else {
for (int i = 0; i < cookies.size(); i++) {
Log.d(TAG, "cookies: " + cookies.get(i).toString());
}
}
resEntity.consumeContent();
HttpGet get = new HttpGet("http://www.bhtelecom.ba/index.php?id=3226&");
get.getParams().setParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, Boolean.FALSE);
HttpResponse responseGET = client.execute(get);
HttpEntity entityGET = responseGET.getEntity();
List<Cookie> cookiesGet = client.getCookieStore().getCookies();
if (cookies.isEmpty()) {
Log.d(TAG, "no cookies");
} else {
for (int i = 0; i < cookiesGet.size(); i++) {
Log.d(TAG, "cookies GET: " + cookiesGet.get(i).toString());
}
}
//a method to check the data, I pass the InputStream to it, and do the operations, I've tried "manually", and passing the InputStream to JSOUP, but without success in either case.
samplemethod(entityGET.getContent());
client.getConnectionManager().shutdown();
} catch (Exception e) {
e.printStackTrace();
}
因此，如果任何人都可以找到自己設置錯誤，不然我找一個方法，使這兩個請求，然後獲取數據，HTTP實體，然後我可以作爲輸入使用（InputStream的）以可愛的JSOUP解析器，這將是驚人的。或者，也許我已經掌握了關於網頁需求的全部內容，而且我需要用不同的參數提出請求，我將不勝感激。我使用Wireshark和Charles Debugging Proxy來創建想法（嘗試這兩種方法，仔細檢查），並且僅找到了會話ID，fe_typo_user和用於跟蹤網站時間等的其他參數，我試過了傳遞給他們，「_ utma」「 _utmb」...等等。
我有一些其他的方法，使用「簡單」，只有POST方法與數據作爲響應，我已經成功地得到了這一點，但這個網站的具體問題讓我瘋狂。在此先感謝您的幫助。
