phonegap 的新手，即使在阅读了有关该主题的所有 SO 帖子后也有困难，就是无法正常工作。
我安装了 org.apache.cordova.whitelist 插件，我在我的 index.html 文件中添加了 Content-Security-Policy 元指令，并且我在我的 config.xml 中添加了适当的和和标签。但是，每次运行应用程序 (android) 时，我都会收到以下错误:
"No Content-Security-Policy meta tag found. Please add one when using the cordova-plugin-whitelist plugin.", source: file:///android_asset/www/plugins/cordova-plugin-whitelist/whitelist.js
这是最基本的索引页面:

最佳答案
仅用于测试目的:注释掉这一行 ->
<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src: 'self' 'unsafe-inline' 'unsafe-eval'" />
那么你的问题就解决了。
