Question

我想使用appium在混合Android应用程序内部截取Webview部分的屏幕截图。

我使用以下代码截取屏幕截图。

    String Screenshotpath = System.getProperty("user.dir") + "/";
    System.out.println(Screenshotpath);
    File scrFile = ((TakesScreenshot) driver)
            .getScreenshotAs(OutputType.FILE);
    System.out.println(scrFile); 
    try {
        FileUtils.copyFile(scrFile, new File(Screenshotpath
                + "screenshotwebview" + ".jpg"));
    } catch (IOException e) {
        e.printStackTrace();
    }

它工作正常，并截取整个屏幕的截图。但是当我尝试将上下文设置为webview并尝试使用上面的代码截取屏幕截图时，它会显示以下错误

org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command.

Original error: Could not proxy. Proxy error: Could not proxy command to remote server.

Original error: Error: ESOCKETTIMEDOUT (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 0 milliseconds

是否可以仅使用Appium获取webview部分的屏幕截图？

任何人都可以帮忙

Answer 1

你可以这样做。

在此之前，你可以这样做。

    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setSupportZoom(true); 
    webView.requestFocusFromTouch();
    webView.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    });
    webView.loadUrl("your url");

并检查版本。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    checkSdkVersion();
    setContentView(R.layout.activity_webview_capture);
}

// check version
private void checkSdkVersion() {
    if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP) {
        WebView.enableSlowWholeDocumentDraw();
    }
}

在清单中添加权限。

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

方式1

private void getScreenshot() {
    float scale = webView.getScale();
    int webViewHeight = (int) (webView.getContentHeight() * scale + 0.5);
    Bitmap bitmap = Bitmap.createBitmap(webView.getWidth(), webViewHeight, Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    webView.draw(canvas);
    // save to the File
    try {
        String fileName = Environment.getExternalStorageDirectory().getPath() + "/webview_capture1.jpg";
        FileOutputStream fos = new FileOutputStream(fileName);
        // Save
        bitmap.compress(Bitmap.CompressFormat.JPEG, 70, fos);
        fos.close();
        Toast.makeText(WebviewFromDraw.this, "Screenshot OK", Toast.LENGTH_LONG).show();
        bitmap.recycle();
    } catch (Exception e) {
        e.getMessage();
    }
}

方式2

private void getScreenshot() {
    Picture picture = webView.capturePicture();
    int width = picture.getWidth();
    int height = picture.getHeight();
    if (width > 0 && height > 0) {
        Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        picture.draw(canvas);
        try {
            String fileName = Environment.getExternalStorageDirectory().getPath()+"/webview_capture3.jpg";
            FileOutputStream fos = new FileOutputStream(fileName);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 70, fos);
            fos.close();
            Toast.makeText(WebviewFromCapture.this, "Screenshot ok", Toast.LENGTH_LONG).show();
            bitmap.recycle();
        } catch (Exception e) {
            Log.e(TAG, e.getMessage());
        }
    }
}
