Android CookieManager setCookie創建多個Cookie

Question

在我的android應用程序中，我有一個webview。它從多個域加載URL。我需要刪除特定域中的所有Cookie。我想保留來自其他域的Cookie。但我需要從一個域中刪除所有Cookie。我願意接受處理我請求的所有其他解決方案。 （注意該域使用http和https）

但是，當我嘗試使用CookieManager.setCookie時，該域的所有可用的cookie都沒有被刪除。當我嘗試寫入該密鑰時，會出現多個Cookie密鑰。

我附上我的代碼如下。您可以在評論行中找到結果。在故事結尾，我得到這個cookie。注意多個值：

public static Vector<String> getCookieAllKeysByCookieString(String pCookies) { 
    if (TextUtils.isEmpty(pCookies)) { 
     return null; 
    } 
    String[] cookieField = pCookies.split(";"); 
    int len = cookieField.length; 
    for (int i = 0; i < len; i++) { 
     cookieField[i] = cookieField[i].trim(); 
    } 
    Vector<String> allCookieField = new Vector<String>(); 
    for (int i = 0; i < len; i++) { 
     if (TextUtils.isEmpty(cookieField[i])) { 
      continue; 
     } 
     if (!cookieField[i].contains("=")) { 
      continue; 
     } 
     String[] singleCookieField = cookieField[i].split("="); 
     allCookieField.add(singleCookieField[0]); 
    } 
    if (allCookieField.isEmpty()) { 
     return null; 
    } 
    return allCookieField; 
} 

我得到禮物餅乾：

"userid=12%34; token=12ased; remember_check=0; userid='-1'; token='-1'; remember_check='-1';" 

其將cookie字符串得到的cookie鑰匙我的助手功能

// I take cookie string for specific URL 
mCookieManager = CookieManager.getInstance(); 
String url2="https://mysite.com"; 
String cookieString = mCookieManager.getCookie(url2); 
Toast.makeText(mContext, "cookie string:\n"+cookieString, Toast.LENGTH_SHORT).show(); 
// result is: userid=12%34; token=12ased; remember_check=0; 

然後我打電話，以取代舊的餅乾。

Vector<String> cookie = CookieUtil.getCookieAllKeysByCookieString(cookieString); 
if (cookie == null || cookie.isEmpty()) { 
    Toast.makeText(mContext, "cookie null", Toast.LENGTH_SHORT).show(); 
} 
if (cookie != null) { 
    int len = cookie.size(); 
    Toast.makeText(mContext, "cookie number: "+len, Toast.LENGTH_SHORT).show(); 
    // result is, cookie number: 3 
    String cookieNames=""; 
    for (int i = 0; i < len; i++) { 
     cookieNames += "\n"+cookie.get(i) ; 
     mCookieManager.setCookie(url2, cookie.get(i) + "='-1';"); 
    } 
    Toast.makeText(mContext, "cookieNames:\n"+cookieNames, Toast.LENGTH_SHORT).show(); 
    // result is: "cookienames: userid token remember_check" 

    mCookieSyncManager.sync(); 

    cookieString = mCookieManager.getCookie(url2); 
    Toast.makeText(mContext, "cookie string:\n"+cookieString, Toast.LENGTH_SHORT).show(); 
    mCookieSyncManager.sync(); 
    // result is: "userid=12%34; token=12ased; remember_check=0; userid='-1'; token='-1'; remember_check='-1';" 
} 

編輯：
我也試過setCookie方法是這樣的：

mCookieManager.setCookie(url2, cookie.get(i) + "=-1;"); 
mCookieManager.setCookie(url2, cookie.get(i) + "=-1"); 

EDIT2：setCookie方法的簽名是這樣的：

/** 
* Sets a cookie for the given URL. Any existing cookie with the same host, 
* path and name will be replaced with the new cookie. The cookie being set 
* must not have expired and must not be a session cookie, otherwise it 
* will be ignored. 
* 
* @param url the URL for which the cookie is set 
* @param value the cookie as a string, using the format of the 'Set-Cookie' 
*    HTTP response header 
*/ 
public void setCookie(String url, String value) { 
    throw new MustOverrideException(); 
} 

雖然我得到的cookie字符串中相同的密鑰（"userid=12%34; token=12ased; remember_check=0; userid='-1'; token='-1'; remember_check='-1';" ）他們會有不同的主機或路徑？

Answer 1

我和Android的CookieManager有過類似的體驗。設置相同的cookie將確實將其添加爲新的cookie。

請嘗試執行this solution。它將使你能夠flush你想要的餅乾remove，然後你就可以再次設置你想要的。

祝你好運！
