Question

我们有一个应用程序，我们在webview中使用 iFrames 进行一些重定向。此重定向发生在具有自定义协议的HTTPS页面上（例如：customProtocol：//）

然后在shouldOverrideUrlLoading中拦截此重定向以执行我们的逻辑。

重定向工作在kitkat及以上，其中有基于铬的webview，但在Android 4.4以下的手机/平板电脑上我们得到**显示不安全内容的页面**错误，它被阻止，shouldOverrideUrlLoading是不叫。

有没有办法允许4.4以下的webview允许https页面中的自定义协议？

我不确定，试试这个

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>App Redirection</title>
</head>
<body>

<!-- iframe used for attempting to load a custom protocol -->
<iframe style="display:none" height="0" width="0" id="loader"></iframe>

<script>(function(){
// For desktop browser, remember to pass though any metadata on the link for deep linking
var fallbackLink = 'http://example.com/my-web-app/'+window.location.search+window.location.hash;
// Simple device detection
var isiOS = navigator.userAgent.match('iPad') || navigator.userAgent.match('iPhone') || navigator.userAgent.match('iPod'),
isAndroid = navigator.userAgent.match('Android');
// Mobile
if (isiOS || isAndroid) {
// Load our custom protocol in the iframe, for Chrome and Opera this burys the error dialog (which is actually HTML)
// for iOS we will get a popup error if this protocol is not supported, but it won't block javascript
document.getElementById('loader').src = 'custom-protocol://my-app'+window.location.search+window.location.hash;
// The fallback link for Android needs to be https:// rather than market:// or the device will try to
// load both URLs and only the last one will win. (Especially FireFox, where an "Are You Sure" dialog will appear)
// on iOS we can link directly to the App Store as our app switch will fire prior to the switch
// If you have a mobile web app, your fallback could be that instead.
fallbackLink = isAndroid ? 'https://play.google.com/store/apps/details?id=com.mycompany.myapp' :
'itms-apps://itunes.apple.com/app/my-app/idxxxxxxxx?mt=8' ;
}
// Now we just wait for everything to execute, if the user is redirected to your custom app
// the timeout below will never fire, if a custom app is not present (or the user is on the Desktop)
// we will replace the current URL with the fallbackLink (store URL or desktop URL as appropriate)
window.setTimeout(function (){ window.location.replace(fallbackLink); }, 1);

Q&A
I have a native desktop app as well, how do I link to a custom protocol handler on the desktop?
IE Only: http://msdn.microsoft.com/en-us/library/ms537512.aspx#Version_Vectors
All Other Browsers: Use a custom plugin like iTunes does: http://ax.itunes.apple.com/detection/itmsCheck.js
