Android Webview通过设置令牌cookie自动登录到https网站 [英] Android Webview auto login to https website by setting token cookie

问题描述

我想要实现的是通过将令牌设置为cookie来自动登录到https网站。

（它适用于Android Chrome浏览器，但不适用于应用程序web view）

基本上，我遇到了两个问题，即将https网址加载到网络视图中并设置了Cookie

第1期

我收到以下日志消息。

无法验证证书链，错误：
java.security.cert.CertPathValidatorException：未找到
证书路径的信任锚点

我尝试覆盖 onReceivedSslError 并调用 handler.proceed（）; p>

  @Override 
 public void onReceivedSslError（WebView视图，SslErrorHandler处理程序，SslError错误）{
 Log.d TAG，==>+ error.toString（））; 
 handler.proceed（）; 
} 
  

但是我仍然看到白页。）

第2期

我有一个登入网址例如 https://www.abc.com/login.html ）

我想实现的是通过设置cookie来自动登录到web视图。

  CookieSyncManager.createInstance .getContext（））; 
 CookieManager cookieManager = CookieManager.getInstance（）; 
 CookieManager.getInstance（）。setAcceptCookie（true）; 
 
 String token = PreferenceHelper.loadTokenFromPreference（this）; 
 
 String sessionCookie =staging =+ token; 
 
 cookieManager.setCookie（https://www.abc.com/aaa/，
 sessionCookie）; 
 CookieSyncManager.getInstance（）。sync（）; 
 
 SystemClock.sleep（1000）; 
  

但是我还是无法自动登录。我看到白页。

我现在不知道的正是我犯错误的地方。

cookieManager。 setCookie 需要第一个参数作为需要设置Cookie的网址，我不知道我需要给哪个网址。

解决方案

我必须添加以下行才能使其正常工作。

  webView.getSettings（）。setAppCachePath（appCachePath）; 
 webView.getSettings（）。setAppCacheEnabled（true）; 
  

What I am trying to achieve is to autologin to a https website by setting a token as a cookie.

( It works on android chrome browser but not in application webview )

Basically I am facing two issue while loading https url into web view with cookie set

Issue 1

I am getting following log message.

Failed to validate the certificate chain, error: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

I tried overriding onReceivedSslError and called handler.proceed(); as below.

@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
    Log.d(TAG, "==> " + error.toString());
    handler.proceed();
}

But still I see white page ( I am assuming Its happening because of certificate issue. )

Issue 2

I have got a login url with me ( e.g https://www.abc.com/login.html )

What I am trying to achieve is auto login into web view by setting a cookie.

CookieSyncManager.createInstance(webView.getContext());
CookieManager cookieManager = CookieManager.getInstance();
CookieManager.getInstance().setAcceptCookie(true);

String token = PreferenceHelper.loadTokenFromPreference(this);

String sessionCookie = "staging=" + token;

cookieManager.setCookie("https://www.abc.com/aaa/",
    sessionCookie);
CookieSyncManager.getInstance().sync();

SystemClock.sleep(1000);

But still I am not able to auto login.Rather I am seeing the white page.

What I am not sure now is exactly where I am making a mistake.

cookieManager.setCookie requires first argument as a url for which cookie needs to set,I am not sure exactly which url i need to give it ?

Can anyone suggest me the right approach to get it working ?

Thanks

解决方案

Well after searching for quite a while I finally got the solution.

I had to add following lines to get it working.

webView.getSettings().setAppCachePath(appCachePath);
webView.getSettings().setAppCacheEnabled(true);
