Answer 1

将以下内容添加到Content-Security-Policy元标记img-src指令:

android-webview-video-poster:

如:

<meta http-equiv="Content-Security-Policy" content="default-src * gap:; script-src * 'unsafe-inline' 'unsafe-eval'; connect-src *; img-src * data: blob: android-webview-video-poster:; style-src * 'unsafe-inline';">
