android - 使用 cookie 访问网站

Question

我正在尝试在 android 中创建一个 webview 来访问一个网站，我编写了一些代码来通过用户名和密码从网站获取 cookie。我得到的结果是：

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

现在我不知道如何使用它来登录网站。请帮我。感谢。

Answer 1

它非常简单。

简答

以下是执行此任务的代码片段：

当我们从登录页面获得第一个响应时，我们通过以下方式存储 Cookie：

List<Cookie> mCookies = null;

 ...

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

下次登录时，我们创建CookieStore

 CookieStore cookieStore = new BasicCookieStore(); 

并存储我们的 Cookie：

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

之后，将 store 提供给 http 客户端：

httpclient.setCookieStore(cookieStore);

就这样。

通过登录连接到强制门户的 Unitest

它的工作代码，以防万一你有兴趣看看它是如何工作的

private static String URL = "";
    List<Cookie> mCookies = null;
    String mHost = null;
