html - 拒绝加载图像 'blob:...' 因为它违反了以下内容安全策略

Question

我收到此错误:

Refused to load the image 'blob:file:///cf368042-bf23-42b6-b07c-54189d3b0e01' because it violates the following Content Security Policy directive: "default-src * 'self' 'unsafe-inline' 'unsafe-eval' data: gap: content:". Note that 'img-src' was not explicitly set, so 'default-src' is used as a fallback.

在尝试加载 mapboxGL map 时。
这是我的 CSP 标签:

<meta http-equiv="Content-Security-Policy" 
    content="
      worker-src blob:; 
      child-src blob: gap:;
      default-src * 'self' 'unsafe-inline' 'unsafe-eval' data: gap: content:">

Answer 1

这是图像和 base64 的修复程序。
需要加img-src 'self' blob: data:;如下:

<meta http-equiv="Content-Security-Policy" 
    content="
      worker-src blob:; 
      child-src blob: gap:;
      img-src 'self' blob: data:;
      default-src * 'self' 'unsafe-inline' 'unsafe-eval' data: gap: content:">
