String url ="http://low2018.byethost32.com/GET01.php?A1=什麼鬼";
WebView webView = findViewById(R.id.web);
webView.loadUrl(url);


CookieManager cookieManager = CookieManager.getInstance();
String cookieStr = cookieManager.getCookie(url);
Log.i("MyLog",cookieStr);

程式碼區塊 你是怎麼弄得?不是沒有支援java?...

你說程式碼區塊啊，android不是java的語法所以我用js。大同小異且可行。


我沒有要用WebView，只想用HttpURLConnection抓看看資料。

我連線是成功，抓取的資料如下。卻找不到cookie的資料。
I/System.out: null = [HTTP/1.1 200 OK]
Cache-Control = [no-cache]
Connection = [keep-alive]
Content-Type = [text/html]
Date = [Sun, 06 May 2018 16:39:57 GMT]
Expires = [Thu, 01 Jan 1970 00:00:01 GMT]
Server = [nginx]
Transfer-Encoding = [chunked]
Vary = [Accept-Encoding]
X-Android-Received-Millis = [1525624724085]
X-Android-Response-Source = [NETWORK 200]
X-Android-Selected-Protocol = [http/1.1]
X-Android-Sent-Millis = [1525624723799]

我找尋網站用了conn.getHeaderFields("Set-Cookie");的方法也抓不到資料。
請問是我權限問題還是其他問題。

謝謝您

直接google 【android httpurlconnection cookie example】


第一筆資料
https://stackoverflow.com/questions/16150089/how-to-handle-cookies-in-httpurlconnection-using-cookiemanager

裡面的code沒有效嗎???

小羊窒息：這篇已看過還是得不到答案。

語法如下：我寫的結果顯示還是「失敗」 cookiesHeader 等於 NULL

單純只為了抓Cookie值。

package com.example.fan.hmp; import android.os.Bundle; import android.os.StrictMode; import android.support.v7.app.AppCompatActivity; import java.io.IOException; import java.net.HttpURLConnection; import java.net.MalformedURLException; import java.net.URL; import java.util.List; import java.util.Map; public class hmp extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_hmp); //解android.os.NetworkOnMainThreadException問題 StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder() .detectDiskReads() .detectDiskWrites() .detectNetwork() // or .detectAll() for all detectable problems .penaltyLog() .build()); StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder() .detectLeakedSqlLiteObjects() .detectLeakedClosableObjects() .penaltyLog() .penaltyDeath() .build()); //============ //http://low2018.byethost32.com/GET01.php java.net.CookieManager msCookieManager = new java.net.CookieManager(); final String COOKIES_HEADER = "Set-Cookie"; try { URL i=new URL("http://low2018.byethost32.com/GET01.php?A1=什麼鬼"); HttpURLConnection conn=(HttpURLConnection)i.openConnection(); Map<String, List<String>> headerFields = conn.getHeaderFields(); List<String> cookiesHeader = headerFields.get(COOKIES_HEADER); if (cookiesHeader != null) { /* for (String cookie : cookiesHeader) { msCookieManager.getCookieStore().add(null, HttpCookie.parse(cookie).get(0)); }*/ System.out.println("成功"); }else { System.out.println("失敗"); } } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }

你的cookie 是在前端設置的 所以比較適合用WebView
document.cookie="__test="+toHex(slowAES.decrypt(c,2,a,b))+"; expires=Thu, 31-Dec-37 23:55:55 GMT; path=/";
也就是說 你必須載入頁面後 並且執行javascript 才會設定cookie
應該是這個原因


這裡是jsp 後端設定cookie的方式

至於PHP的話 我就不清楚了

其實webView可以不用顯示在畫面上

WebView寫法
public class MainActivity extends AppCompatActivity { String urlStr ="http://low2018.byethost32.com/GET01.php?A1=什麼鬼"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); WebView webView = new WebView(this); WebSettings webSettings = webView.getSettings(); webSettings.setJavaScriptEnabled(true); webView.setWebViewClient(new WebViewClient(){ @Override public void onPageFinished(WebView view, String url) { super.onPageFinished(view, url); CookieManager cookieManager = CookieManager.getInstance(); cookieManager.setAcceptCookie(true); String cookieStr = cookieManager.getCookie(urlStr); Log.i("MyLog",cookieStr); } }); webView.loadUrl(urlStr ); } }
