webview_flutter官方插件的增强-对inputfile和权限请求的支持

# webview_flutter官方插件的增强-Android上对inputfile和权限请求的支持

插件升级到最新版本(较老的版本上没有实现onPermissionRequest回调,最新的版本上没有实现onGeolocationPermissionsShowPrompt回调).

使用aop切入插件的Android代码,实现对应的onShowFileChooser和onPermissionRequest方法.

如下所示:

@Aspect
public class FlutterWebChromeClientAspect {

    private static final String TAG = "WebChromeClientAspect";


    //public boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback, FileChooserParams fileChooserParams)
    @Around("execution(* io.flutter.plugins.webviewflutter.WebChromeClientHostApiImpl.WebChromeClientImpl.onShowFileChooser(..))")
    public Object onShowFileChooser(ProceedingJoinPoint joinPoint) throws Throwable {
        WebView webView = (WebView) joinPoint.getArgs()[0];
        ValueCallback<Uri[]> filePathCallback = (ValueCallback) joinPoint.getArgs()[1];
        WebChromeClient.FileChooserParams fileChooserParams = (WebChromeClient.FileChooserParams) joinPoint.getArgs()[2];

        LogMethodAspect.logBefore(true, TAG, joinPoint, new LogMethodAspect.IBefore() {
            @Override
            public void before(JoinPoint joinPoin, String desc) {
                LogMethodAspect.IBefore.super.before(joinPoin, desc);
            }
        });

        return new FileChooseImpl().onShowFileChooser(webView, filePathCallback, fileChooserParams);
    }


    //public void onPermissionRequest(PermissionRequest request)
    @Around("execution(* io.flutter.plugins.webviewflutter.WebChromeClientHostApiImpl.WebChromeClientImpl.onPermissionRequest(..))")
    public void onPermissionRequest(ProceedingJoinPoint joinPoint) throws Throwable {
        PermissionRequest request = (PermissionRequest) joinPoint.getArgs()[0];

        LogMethodAspect.logBefore(true, TAG, joinPoint, new LogMethodAspect.IBefore() {
            @Override
            public void before(JoinPoint joinPoin, String desc) {
                LogMethodAspect.IBefore.super.before(joinPoin, desc);
            }
        });
         new JsPermissionImpl().onPermissionRequest(request);
    }

    //public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissions.Callback callback)
    @Around("execution(* io.flutter.plugins.webviewflutter.WebChromeClientHostApiImpl.WebChromeClientImpl.onGeolocationPermissionsShowPrompt(..))")
    public void onGeolocationPermissionsShowPrompt(ProceedingJoinPoint joinPoint) throws Throwable {
        String origin = (String) joinPoint.getArgs()[0];
        GeolocationPermissions.Callback callback = (GeolocationPermissions.Callback) joinPoint.getArgs()[1];
        LogMethodAspect.logBefore(true, TAG, joinPoint, new LogMethodAspect.IBefore() {
            @Override
            public void before(JoinPoint joinPoin, String desc) {
                LogMethodAspect.IBefore.super.before(joinPoin, desc);
            }
        });
        new JsPermissionImpl().onGeolocationPermissionsShowPrompt(origin,callback);
    }


}

此处JsPermissionImpl,FileChooseImpl两个类引用自:

   api 'com.github.hss01248.utilcodeEnhance:media:1.2.7'
   api 'com.github.hss01248.utilcodeEnhance:baseWebview:1.2.7'
   api 'com.github.hss01248.StartActivityResult:activityresult:1.1.7'

其内部对input file标签,权限申请做了非常完善的适配,见webview文件选择-input-file适配 (opens new window)

然后按aspectjx的配置要求配置相关包名即可.

便捷使用方式: 脚本一键引入:

apply from: 'https://raw.githubusercontent.com/hss01248/flipperUtil/dev/remote3.gradle

并在gradle.properties里配置:

use_aspectjx_in_release=true
