Android页面嵌套了一个h5，H5页面内部有用户登陆页面，发现h5页面的登陆功能无法使用，一直登陆失败。和web那边商量一会，发现js写入的cookie丢失了。所有需要Android这边在重写写入一次。

mWebView = view.findViewById(R.id.mall_view);

settings = mWebView.getSettings();

settings.setJavaScriptEnabled(true);

settings.setLoadsImagesAutomatically(true);

settings.setDomStorageEnabled(true);

//不缓存

settings.setCacheMode(WebSettings.LOAD_NO_CACHE);

mWebView.setWebViewClient(new MyWebViewClient());

class MyWebViewClient extends WebViewClient{

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

if (url != "") {

//重点写入cookie

HashMap map = new HashMap<>();

map.put("Referer", view.getUrl());

view.loadUrl(url, map);

}

return true;

}

@Override

public void onPageFinished(WebView view, String url) {

//获取登陆后的cookie,看是否写入

CookieManager cookieManager = CookieManager.getInstance();

String CookieStr = cookieManager.getCookie(url);

super.onPageFinished(view, url);

}

}

以上就解决了登陆失败的问题！

还有就是登陆状态的同步，需要保存和设置cookie

/**

* 获取接口中的cookie

* @param loginUrl

*/

private void syncCookie(final String loginUrl) {

new Thread(new Runnable() {

@Override

public void run() {

try {

StringBuilder builder = new StringBuilder();

URL url= null;

byte[] data = builder.toString().getBytes("UTF-8");

url = new URL(loginUrl);

HttpURLConnection connection =

(HttpURLConnection) url.openConnection();

connection.setDoOutput(true);

connection.setRequestProperty("Content-Type",

"application/x-www-form-urlencoded");

connection.setRequestProperty("Content-Length",

Integer.toString(data.length));

connection.setRequestMethod("GET");

connection.setInstanceFollowRedirects(false);

OutputStream os = connection.getOutputStream();

os.write(data);

os.close();

int aRstCode = connection.getResponseCode();

if (aRstCode == HttpURLConnection.HTTP_OK) {

cookie = connection.getHeaderField("Set-Cookie");

}

} catch (MalformedURLException e) {

e.printStackTrace();

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

} catch (ProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

}).start();

}

//设置cookie

if(cookie != null && cookie.length() > 0){

android.webkit.CookieManager cookieManager =

android.webkit.CookieManager.getInstance();

cookieManager.setAcceptCookie(true);

cookieManager.setCookie(SysParam.shoppingMall, cookie);

CookieSyncManager.getInstance().sync();

}

补充知识：android webview带cookie访问url

问题描述

在原生和h5混合开发的时候会遇到这么一个问题,用webview加载某个url时,你只是app登录了账号,但是网页却没有,所有会禁止访问此url,webview就会显示白屏。

所以要访问此url，需要带上cookie进行访问。这个cookie就是用app登录时所存储的cookie

实现方法和一些环境

网络请求方式

HttpsUrlConnection

这里既然用到了HttpsUrlConnection 说明我所加载的url是https协议

所以webview加载的时候会白屏

报错信息:

1

这是由于证书和域名不匹配,我的调试环境在内网服务器上,而证书是绑定在公网的域名上的。

所以需要webView跳过证书验证,

跳过证书验证

webView.setWebViewClient(new WebViewClient() {

@Override

public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {

Log.e("app_name",error.toString());

handler.proceed();

}

});

然后设置cookie

cookie是在app使用HttpsUrlConnect发起登录请求时保存在本地的cookie

app登录成功后保存cookie到本地

SharedPreferences sharedPreferences = getSharedPreferences("login",MODE_PRIVATE);

SharedPreferences.Editor editor = sharedPreferences.edit();

String cookieval = conn.getHeaderField("Set-Cookie");

editor.putString("all_cookie",cookieval);

是一个结构如下的值：

SESSION=f19b09e9-69b2-4ab4-9daf-ea224523a092; Path=/; Secure; HttpOnly

写入cookie

/**

*@param cookie 上面获取到的存储在本地的cookie字符串

*@param url 要加载的页面url

*/

private void setCookie(String cookie,String url) {

String StringCookie = cookie;

CookieManager cookieManager = CookieManager.getInstance();

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

cookieManager.removeSessionCookies(null);

cookieManager.flush();

} else {

cookieManager.removeSessionCookie();

CookieSyncManager.getInstance().sync();

}

cookieManager.setAcceptCookie(true);

cookieManager.setCookie(url, StringCookie);

}

所有关键代码

SharedPreferences sharedPreferences = getSharedPreferences("login",MODE_PRIVATE);

String cookie = sharedPreferences.getString("session","");

String all_cookie = sharedPreferences.getString("all_cookie","");

Log.e("weibiao",all_cookie);

webView = findViewById(R.id.other_account_service_webview);

webView.setWebViewClient(new WebViewClient() {

@Override

public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {

Log.e("weibiao",error.toString());

handler.proceed();

}

});

initWebViewSettings();//webview的一些设置

setCookie(all_cookie,url);//在loadurl之前调用此方法

webView.loadUrl(url);
