以下是我正在处理的website，当我尝试打开https://CurieDoc.com/blog时，有人可以建议我为什么会收到错误（违反内容安全政策）。我使用路径/blog使用Hexo Blog
这是我得到的错误：
拒绝加载图片，因为它违反了以下内容 安全政策指令：＆＃34;默认-src＆＃39; self＆＃39;＆＃34;。请注意＆＃39; img-src＆＃39; 没有明确设置，所以＆＃39; default-src＆＃39;用作后备
正在设置的CSP相关标头：
// security headers
res.setHeader('Content-Security-Policy', "default-src 'self'")
res.setHeader('X-Content-Type-Options', 'nosniff')
// standard headers
res.setHeader('Content-Type', 'text/html; charset=utf-8')
res.setHeader('Content-Length', Buffer.byteLength(body, 'utf8'))
我在这个问题上经历了几个类似的问题，但我无法找到解决问题的答案。任何帮助/指导将不胜感激。
以下是我要投放的Index.html页面
