的WebView和Android的饼干 [英] WebView and Cookies on Android

问题描述

我有工作正常，通过定期的浏览器，通过机器人的WebView但是使用时对appspot一个应用程序，它不能设置和读取的cookies。我不是让饼干外这个Web应用程序顺便说一句，一旦URL是由web视图，所有的处理，IDS等去可以呆在那里，我需要的是会话管理的应用程序中。首先屏幕还加载罚款，所以我知道的WebView +服务器交互不破。

I have an application on appspot that works fine through regular browser, however when used through Android WebView, it cannot set and read cookies. I am not trying to get cookies "outside" this web application BTW, once the URL is visited by WebView, all processing, ids, etc. can stay there, all I need is session management inside that application. First screen also loads fine, so I know WebView + server interactivity is not broken.

我看着WebSettings类中，有像setEnableCookies没有呼叫。

I looked at WebSettings class, there was no call like setEnableCookies.

我打开网址是这样的：

public class MyActivity extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);       
    WebView webview = new WebView(this);
    setContentView(webview);      
    webview.loadUrl([MY URL]);
  }
  .. 
}

任何想法？

Any ideas?

推荐答案

我想通了，这是怎么回事。

I figured out what's going on.

当我通过服务器端的操作（网址访问）加载一个页面，并查看从web视图里面那个动作返回的HTML，即第一个动作/页的web视图内运行。但是，当你点击，在你的web应用程序动作命令，这些操作任何一个环节开始一个新的浏览器。这就是为什么cookie的信息丢失了，因为你的web视图设置第一个cookie信息消失了，我们这里有一个单独的程序。

When I load a page through a server side action (a url visit), and view the html returned from that action inside a Webview, that first action/page runs inside that Webview. However, when you click on any link that are action commands in your web app, these actions start a new browser. That is why cookie info gets lost because the first cookie information you set for Webview is gone, we have a seperate program here.

您必须拦截点击web视图使浏览从来没有离开应用程序，一切都保持相同的web视图里面。

You have to intercept clicks on Webview so that browsing never leaves the app, everything stays inside the same Webview.

  WebView webview = new WebView(this);      
  webview.setWebViewClient(new WebViewClient() {  
      @Override  
      public boolean shouldOverrideUrlLoading(WebView view, String url)  
      {  
        view.loadUrl(url); //this is controversial - see comments and other answers
        return true;  
      }  
    });                 
  setContentView(webview);      
  webview.loadUrl([MY URL]);

这解决了这个问题。
