Question

当我点击页面servlet发布数据上的按钮时，我想下载带有webview的文件。请求网址类似于website.com/download.htm。此网址响应包含文件网址作为附件但没有任何反应，我在Chrome远程调试工具中看到此响应：

我不是servlet页面的所有者，这是我的应用程序代码：

    web = (WebView) findViewById(R.id.webView);
    WebSettings webSettings = web.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setGeolocationEnabled(true);
    webSettings.setSupportMultipleWindows(true);
    webSettings.setAllowContentAccess(true);
    webSettings.setAllowFileAccess(true);
    webSettings.setAllowFileAccessFromFileURLs(true);
    webSettings.setAppCacheEnabled(true);
    webSetting.setSupportMultipleWindows(true);
    webSettings.setAllowUniversalAccessFromFileURLs(true);
    webSettings.setDomStorageEnabled(true);
    web.setWebChromeClient(new WebChromeClient() {
        @Override
        public void onReceivedTitle(WebView view, String title) {
            getWindow().setTitle(title);
        }
    });
    web.setWebViewClient(new WebViewClient() {
        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Log.d("error", "" + errorCode + description + failingUrl);
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            Log.d("started", url);
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            Log.d('url', url);
            return false;
        }

        web.loadUrl("https://website.com");
        web.setDownloadListener(new DownloadListener() {
            public void onDownloadStart (String url, String userAgent, String contentDisposition, String mimetype,
            long contentLength)
            {
                Log.d("download", url + "\n" + mimetype + contentDisposition + contentLength);
                DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
                final String[] separated = url.split("/");
                final String myFile = separated[separated.length - 1];
                request.allowScanningByMediaScanner();
                request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
                request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, myFile);
                DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
            }
        });

    });

我用chrome和stock浏览器检查了网站，文件下载得很好，但没有在webview上，我检查了不同的网站下载文件; webview使用直接网址在其他网站上下载文件。下载侦听器不适用于该URL。我在oncatstarted和onPagefinish的logcat中看到了website.com/download.htm，但是没有在shouldOverrideUrlLoading上看到。其他页面显示在所有三个功能上。有什么问题？

webview不从servlet响应
