Angular4 Content-Security-Protocol 拒绝加载字体

我刚从 Angular1.6 -> 4 升级，我有点被 Content-Security-Protocol 错误困住了:

http://localhost:4200/:1 GET http://localhost:4200/ 404 (Not Found)
localhost/:1 Refused to load the font 'data:font/woff;base64,d09GRgABAAAAAIt0ABEAAAABQDwAAQABAAAAAAAAAAAAAAAAAAAAACwKGBmIIpVWLACJWGwAUVjI2KwAiNEswkKAwIrswsQAwIrsxEWAwIrWbIEKAZFUkSzCxAEAisA' 
because it violates the following Content Security Policy directive: "default-src 'self'". Note that 'font-src' was not explicitly set, so 'default-src' is used as a fallback.

就像我尽我所能，让我也发布我的 JSON 文件!有人可以帮我了解到底发生了什么，为什么它不起作用以及其他可能的解决方案吗？而且，我还没有用 manifest.JSON 尝试过它....我在这个项目上有一定的经验，所以任何帮助都将不胜感激!

<!doctype html>
<html lang="en">
<head>
  <meta http-equiv="Content-Security-Policy" content="
        default-src 'none';
        style-src 'self' 'unsafe-inline';
        font-src * data:;
        " />
  <meta charset="utf-8">
  <title>Comp</title>
  <base href="/">

最佳答案

感谢@sideshowbarker 的评论:

sounds like you have Content-Security-Policy header with a stricter policy than what you’re trying to set with that meta element in the document. You can’t set a less-strict policy that way. You need to change the header value instead. See stackoverflow.com/questions/42960811/ … and stackoverflow.com/questions/44732431/ …

错误是由模块内更严格的 CSP 引起的，因此请尝试在 .ts 文件中禁用模块导入，这就是我所做的。

祝你好运!
