android - webview 拦截资源的几个方法和特点

看下面的代码,就可以看出端倪来了

onPageStarted, 触发的url是====http://yunbih5.sweetysoft.com/#/bindAccountToDevice?client=android&language=en


shouldInterceptRequest, 触发的url是====http://app.yun.com/v1/markets

shouldInterceptRequest, 触发的url是====http://yunbih5.sweetysoft.com/#/xxxDevice?client=android&language=en
shouldInterceptRequest, 触发的url是====http://yunbih5.sweetysoft.com/#/xxxDevice?client=android&language=en

    public class MyWebViewClient extends WebViewClient {
        // 在上面log中没有看到, 貌似也是可以拦截的..... 需要进一步搜集日志
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            Log.d(TAG, "shouldOverrideUrlLoading, 触发的url是====" + url);
            //FIXME  姜瑶确认下,这里是否有用.
//            view.loadUrl(appendParameters(url));
            return false;
        }

        /**
         *   触发的都是基本的URL页面(无法拦截vuejs内的跳转)
         */
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            Log.d(TAG, "onPageStarted, 触发的url是====" + url);
            super.onPageStarted(view, url, favicon);
        }

        拦截到的, 是所有的URL(除了 正常的Url 还包括图片,js, css) 
        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
            Log.d(TAG, "shouldInterceptRequest, 触发的url是====" + url);
            if(url.contains("__webpack_hmr")) {
                Log.d(TAG, "return empty response on __webpack_hmr");
                return new WebResourceResponse(null,null, null);
            }
