Question

我正在尝试在android中创建一个webview来访问一个网站，我做了一些代码，通过用户名和密码从网站上获取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登录网站。请帮我。感谢。

Answer 1

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回复时，我们通过这种方式存储Cookie：

List<Cookie> mCookies = null;

 ...

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

下次登录时，我们会创建CookieStore

 CookieStore cookieStore = new BasicCookieStore();

并存储我们的Cookie：

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

之后，向http客户端提供商店：

httpclient.setCookieStore(cookieStore);

就是这样。
