Android WebView Cookie问题

Question

我有一个服务器,它向我的Android应用程序发送一个会话cookie,用于认证通信.我正在尝试使用指向同一服务器的URL加载WebView,并且我正在尝试传递会话cookie以进行身份​​验证.我观察到它间歇性地工作,但我不知道为什么.我使用相同的会话cookie在我的服务器上进行其他调用,这些调用永远不会失败.我只是在尝试在WebView中加载URL时才发现此问题,并且每次都不会发生这种情况.很沮丧.

下面是我用来执行此操作的代码.任何帮助将不胜感激.

String myUrl = ""http://mydomain.com/"; 
CookieSyncManager.createInstance(this); 
CookieManager cookieManager = CookieManager.getInstance(); 
Cookie sessionCookie =  getCookie(); 
if(sessionCookie != null){ 
    String cookieString = sessionCookie.getName() +"="+sessionCookie.getValue()+"; domain="+sessionCookie.getDomain(); 
    cookieManager.setCookie(myUrl, cookieString); 
    CookieSyncManager.getInstance().sync(); 
} 

WebView webView = (WebView) findViewById(R.id.webview); 
webView.getSettings().setBuiltInZoomControls(true); 
webView.getSettings().setJavaScriptEnabled(true); 
webView.setWebViewClient(new MyWebViewClient()); 
webView.loadUrl(myUrl);

谢谢justingrammens!这对我有用,我设法在DefaultHttpClient请求和WebView活动中共享cookie:

//------- Native request activity
private DefaultHttpClient httpClient;
public static Cookie cookie = null;

//After Login
List<Cookie> cookies = httpClient.getCookieStore().getCookies();
for (int i = 0; i < cookies.size(); i++) {
    cookie = cookies.get(i);
}

//------- Web Browser activity
Cookie sessionCookie = myapp.cookie;
CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
if (sessionCookie != null) {
    cookieManager.removeSessionCookie();
    String cookieString = sessionCookie.getName() + "=" + sessionCookie.getValue() + "; domain=" + sessionCookie.getDomain();
    cookieManager.setCookie(myapp.domain, cookieString);
    CookieSyncManager.getInstance().sync();
}

解决方案:Webview CookieSyncManager

CookieSyncManager cookieSyncManager = CookieSyncManager.createInstance(mWebView.getContext());
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);
cookieManager.removeSessionCookie();
cookieManager.setCookie("http://xx.example.com","mid="+MySession.GetSession().sessionId+" ; Domain=.example.com");
cookieSyncManager.sync();

String cookie = cookieManager.getCookie("http://xx.example.com");

Log.d(LOGTAG, "cookie ------>"+cookie);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new TuWebViewClient());
mWebView.loadUrl("http://xx.example.com");

感谢Android破坏了我的星期天...下面是修复我的应用程序的内容(在您初始化webview之后)

if ( Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ) {

  CookieManager cookieManager = CookieManager.getInstance();

  cookieManager.setAcceptThirdPartyCookies( webView, true );

}

我应该说上面的答案可能会有效,但在我的情况下,当Android进入v5 +我的android webview javascript'apps'时就已经死了.

解决方案是给Android足够的时间来处理cookie.您可以在此处找到更多信息:http://code.walletapp.net/post/46414301269/passing-cookie-to-webview

Answer 5

我会将该会话 cookie 保存为首选项，并用它强制重新填充 cookie 管理器。听起来会话cookie在不存活的Activity重新启动中
