使用Cookie訪問一個網站

Question

我想在android中創建一個webview訪問到一個網站，我做了一些代碼，從用戶名和密碼從網站獲取cookie。我得到的結果是：

[version: 0][name: MoodleSession][value: arkitgq9pabpnjka5l0qbj75u1][domain: 192.168.1.105][path: /moodle/][expiry: null] 

現在我不知道如何使用它來登錄到網站。請幫幫我。 謝謝。

Answer 1

它非常簡單。

簡答

這裏的代碼片段，做這個任務：

當我們從登陸頁面1日迴應，我們存儲cookie通過這種方式：

List<Cookie> mCookies = null; 

... 

mCookies = httpclient.getCookieStore().getCookies(); 

下一頁登錄時，我們創建CookieStore

CookieStore cookieStore = new BasicCookieStore(); 

塊

和存儲我們的餅乾：

for(Cookie cook : mCookies){ 
    cookieStore.addCookie(cook); 
} 

後，店內提供在HTTP客戶端：

httpclient.setCookieStore(cookieStore); 

這就是全部。

其工作代碼，以防萬一，看看它是如何工作
