WebViewClient :: onReceivedSslError不被调用

Question

I have attached my WebViewClient implementation to my WebView.

appView.setWebViewClient(new AppViewClient());

My onReceivedSslError and onReceivedError implementations are called with all expected errors except for Mixed Content error.

My implementation for both methods:

Log.i(TAG, "Error Cought");

As I said, they are called on various errors except the Mixed Content error. My request is blocked without calling either of these methods.

Answer 1

Which API version are you using? MIX CONTENT was allowed, by default, before 21.

You can try adding this setting in web view:

webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_NEVER_ALLOW);

For API level below 21 :

try {
    Method m = WebSettings.class.getMethod("setMixedContentMode", int.class);
    if ( m != null ) {

     m.invoke(webView.getSettings(), 1); //MIXED_CONTENT_NEVER_ALLOW

    }
}
catch (Exception ex) {

}

Good to know that you already know about MixedContentMode :) I can suggest 2 things to try.

1. Use console message to identify this error. You can do a string match to check the MIX CONTENT error.

myWebView.setWebChromeClient(new WebChromeClient() {
  public void onConsoleMessage(String message, int lineNumber, String sourceID) {
    Log.d("MyApplication", message + " -- From line "
                         + lineNumber + " of "
                         + sourceID);
  }
});

2. Intercept request and check the url. Check the WebActivity implementation in source code .

    mWebView.setWebViewClient(new WebViewClient() { @Override public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) { String url = request.getUrl().toString(); if (!URLUtil.isHttpsUrl(url)) { Logger.loge("Secure connection required, but insecure URL requested " + "explicitly, or as a part of the page."); return createNewSecurityErrorResponse(); } return super.shouldInterceptRequest(view, request); } }); private WebResourceResponse createNewSecurityErrorResponse() { WebResourceResponse response = new WebResourceResponse("text/plain", "UTF-8", null); response.setStatusCodeAndReasonPhrase(HTTP_FORBIDDEN, "Secure connection required"); return response; }
