Question

在我的应用程序中，我正在使用http post向服务器发送设备ID，然后我收到会话ID。现在我需要在webviewclient中获取会话cookie。我做了一些研究，发现了这个：

问题是解决方案对我不起作用。我一直在这一行上收到错误：

List<Cookie> cookies = httpClient.getCookieStore().getCookies();

对于HttpClient类型，未定义getCookieStore（）方法。我应该加载所有正确的库，所以我不知道为什么我一直收到错误。

这是我的代码，也许有人可以帮我实现一个解决方案，将会话cookie放入我的网页视图。

提前致谢！

Answer 1

我刚刚碰到了同样的事情。我知道这是一个老帖子，但也许它会帮助其他人。

问题在于声明postData（）。

现在该行是： HttpClient httpclient = new DefaultHttpClient();



It should be:

DefaultHttpClient httpclient = new DefaultHttpClient(); 看到这个：http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/client/DefaultHttpClient.html

在webview中使用来自httpclient的cookie
