Android頁(yè)面嵌套了一個(gè)h5，H5頁(yè)面內(nèi)部有用戶登陸頁(yè)面，發(fā)現(xiàn)h5頁(yè)面的登陸功能無(wú)法使用，一直登陸失敗。和web那邊商量一會(huì)，發(fā)現(xiàn)js寫入的cookie丟失了。所有需要Android這邊在重寫寫入一次。

mWebView = view.findViewById(R.id.mall_view); settings = mWebView.getSettings(); settings.setJavaScriptEnabled(true); settings.setLoadsImagesAutomatically(true); settings.setDomStorageEnabled(true); //不緩存 settings.setCacheMode(WebSettings.LOAD_NO_CACHE); mWebView.setWebViewClient(new MyWebViewClient()); class MyWebViewClient extends WebViewClient{ @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { if (url != '') {//重點(diǎn)寫入cookieHashMap<String, String> map = new HashMap<>();map.put('Referer', view.getUrl());view.loadUrl(url, map); } return true; } @Override public void onPageFinished(WebView view, String url) { //獲取登陸后的cookie,看是否寫入 CookieManager cookieManager = CookieManager.getInstance(); String CookieStr = cookieManager.getCookie(url); super.onPageFinished(view, url); } }

以上就解決了登陸失敗的問(wèn)題！

還有就是登陸狀態(tài)的同步，需要保存和設(shè)置cookie

/** * 獲取接口中的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(); } //設(shè)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(); }

補(bǔ)充知識(shí)：android webview帶cookie訪問(wèn)url

問(wèn)題描述

在原生和h5混合開(kāi)發(fā)的時(shí)候會(huì)遇到這么一個(gè)問(wèn)題,用webview加載某個(gè)url時(shí),你只是app登錄了賬號(hào),但是網(wǎng)頁(yè)卻沒(méi)有,所有會(huì)禁止訪問(wèn)此url,webview就會(huì)顯示白屏。

所以要訪問(wèn)此url，需要帶上cookie進(jìn)行訪問(wèn)。這個(gè)cookie就是用app登錄時(shí)所存儲(chǔ)的cookie

實(shí)現(xiàn)方法和一些環(huán)境

網(wǎng)絡(luò)請(qǐng)求方式

HttpsUrlConnection

這里既然用到了HttpsUrlConnection 說(shuō)明我所加載的url是https協(xié)議

所以webview加載的時(shí)候會(huì)白屏

報(bào)錯(cuò)信息:

1

這是由于證書和域名不匹配,我的調(diào)試環(huán)境在內(nèi)網(wǎng)服務(wù)器上,而證書是綁定在公網(wǎng)的域名上的。

所以需要webView跳過(guò)證書驗(yàn)證,

跳過(guò)證書驗(yàn)證

webView.setWebViewClient(new WebViewClient() { @Override public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {Log.e('app_name',error.toString());handler.proceed(); } });

然后設(shè)置cookie

cookie是在app使用HttpsUrlConnect發(fā)起登錄請(qǐng)求時(shí)保存在本地的cookie

app登錄成功后保存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);

是一個(gè)結(jié)構(gòu)如下的值：

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

寫入cookie

/***@param cookie 上面獲取到的存儲(chǔ)在本地的cookie字符串*@param url 要加載的頁(yè)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); }

所有關(guān)鍵代碼

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的一些設(shè)置 setCookie(all_cookie,url);//在loadurl之前調(diào)用此方法 webView.loadUrl(url);

以上這篇解決Android webview設(shè)置cookie和cookie丟失的問(wèn)題就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
