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。

我阅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:

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");

还有一些:

   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 的回答):

    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;
}
}

EDIT2:终于成功了!!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;
}

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 fragment 上添加 onPageFinished:getUrl = view.getUrl();

谢谢。

最佳答案

在您的代码中,您所做的似乎与您想做的相反(从 Webview 获取 cookie 并在 HttpClient 中设置)

编辑:来自 Mor Haviv 的回答 -

您需要定义一个全局变量来存储 View 中的当前 url -

private static String getUrl;

从 webview 获取 cookie -

@Override
public void onPageFinished(WebView view, String url){
getUrl = view.getUrl();
String cookies = CookieManager.getInstance().getCookie(getUrl);
Log.d(TAG, "All the cookies in a string:" + cookies);
}

Reference for above code

在您的 HttpClient 中设置这个名为“cookies”的字符串 -

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;

}
//And, use the same 'getUrl' here to fetch the cookie. (Haviv's addition)
String cookies = CookieManager.getInstance().getCookie(getUrl);
BasicCookieStore lCS = getCookieStore(cookies, YOUR_APP_DOMAIN);

HttpContext localContext = new BasicHttpContext();
DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.setCookieStore(lCS);
localContext.setAttribute(ClientContext.COOKIE_STORE, lCS);

附言 - 将您的应用程序域置于“YOUR_APP_DOMAIN”而且,我无法检查代码,因为我没有您的域。
