使用SDK30在Android webview中获取摄像头图像上传的空intent.getDataString()

<uses-permission android:name="android.permission.CAMERA" />

WebView webView = findViewById(R.id.webView);
webView.setWebChromeClient(new WebChromeClient() {
    @Override
    public void onPermissionRequest(PermissionRequest request) {
        // 处理权限请求
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            request.grant(request.getResources());
        }
    }

    @Override
    public void onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback, FileChooserParams fileChooserParams) {
        // 处理文件选择
        // 在这里可以打开系统相机或相册，获取图像文件的Uri，并将其传递给filePathCallback
        // 例如：
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent, REQUEST_IMAGE_CAPTURE);
    }
});

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        // 处理从相机返回的图像数据
        Uri imageUri = data.getData();
        String imageDataString = imageUri.toString();
        // 将图像数据上传到服务器或进行其他处理
    }
}
