我有一个登录 webview 和 httpclient 需要确认用户是否登录。
问题是 webview 和 httpclient 正在使用其他 cookie，因此 httpclient 无法获取 webview cookie。
我读了很多人的问题和教程，但没有任何效果。我读到的一些东西：
- ANDROID：Webview 和 httpclient 之间共享会话
- Android中webview与java http客户端之间的Http会话同步
- 如何从 HttpClient 获取 cookie？
我在 Android 开发和其他网站上阅读了一些其他教程，但没有任何效果。
另一个帖子：https://stackoverflow.com/questions/28052461/syncing-webview-with-httpclient
问题是 cookie 不会同步。
我尝试过的东西：
WebView webview;
webview = (WebView) rootView.findViewById(R.id.webview);
webview.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
CookieSyncManager.getInstance().sync();
}
});
webview.getSettings().setDomStorageEnabled(true);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setUseWideViewPort(true);
webview.setWebChromeClient(new WebChromeClient());
webview.loadUrl("http://www.klh-dev.com/lehava/lehava/system/mlogin.php");
还有更多：
public String IsLoggedIn() {
new Thread(new Runnable() {
@Override
public void run() {
HttpClient client=new DefaultHttpClient();
HttpGet get=new HttpGet(url);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
try {
response_str=client.execute(get,responseHandler);
System.out.println(response_str);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Cookie sessionInfo;
List<Cookie> cookies = client.getCookieStore().getCookies();
if (! cookies.isEmpty()){
CookieSyncManager.createInstance(getApplicationContext());
CookieManager cookieManager = CookieManager.getInstance();
for(Cookie cookie : cookies){
sessionInfo = cookie;
String cookieString = sessionInfo.getName() + "=" + sessionInfo.getValue() + "; domain=" + sessionInfo.getDomain();
cookieManager.setCookie(URLn, cookieString);
CookieSyncManager.getInstance().sync();
}
}
}
}).start();
return response_str;
}
*httpget返回1或0
我想从 webview 获取 cookie 并在我的 httpclient 请求中使用它们
编辑（添加了 darpan 的答案）：
public static BasicCookieStore getCookieStore(String cookies, String domain) {
String[] cookieValues = cookies.split(";");
BasicCookieStore cs = new BasicCookieStore();
BasicClientCookie cookie;
for (int i = 0; i < cookieValues.length; i++) {
String[] split = cookieValues[i].split("=");
if (split.length == 2)
cookie = new BasicClientCookie(split[0], split[1]);
else
cookie = new BasicClientCookie(split[0], null);
cookie.setDomain(domain);
cs.addCookie(cookie);
}
return cs;
}
public String IsLoggedIn() {
new Thread(new Runnable() {
@Override
public void run() {
String cookies = CookieManager.getInstance().getCookie("http://klh-dev.com/lehava/lehava/system/isloggedin.php");
BasicCookieStore lCS = getCookieStore(cookies, "klh-dev.com");
HttpContext localContext = new BasicHttpContext();
DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.setCookieStore(lCS);
localContext.setAttribute(ClientContext.COOKIE_STORE, lCS);
HttpGet get=new HttpGet("http://klh-dev.com/lehava/lehava/system/isloggedin.php");
ResponseHandler<String> responseHandler = new BasicResponseHandler();
try {
result=httpclient.execute(get,localContext);
response_str = EntityUtils.toString(result.getEntity());
System.out.println(response_str);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();
return response_str;
}
}
编辑2：终于有效了！这是我的代码：
public static String IsLoggedIn() {
new Thread(new Runnable() {
@Override
public void run() {
String cookies = CookieManager.getInstance().getCookie(getUrl);
BasicCookieStore lCS = getCookieStore(cookies, "klh-dev.com");
HttpContext localContext = new BasicHttpContext();
DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.setCookieStore(lCS);
localContext.setAttribute(ClientContext.COOKIE_STORE, lCS);
HttpGet get = new HttpGet("http://klh-dev.com/lehava/lehava/system/isloggedin.php");
try {
result=httpclient.execute(get,localContext);
response_str = EntityUtils.toString(result.getEntity());
System.out.println(response_str);
((MainActivity) getContext).UpdateMenu();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();
return response_str;
}
以及关于 getUrl 变量。
我必须像这样设置一个全局变量：
private static String getUrl;
public String getUrl() {
return getUrl;
}
我必须在每个片段上添加 onPageFinished：getUrl = view.getUrl();
谢谢。
