内容安全策略 (CSP)
为了减轻跨站点脚本问题 Chrome 的扩展系统实现了 Content Security Policy (CSP) which introduces some strict policies that will make extensions more secure by default and provides us the ability to create and enforce rules governing the types of content that can be loaded and executed by your extensions and applications. CSP works as a block/allowlisting mechanism for resources loaded or executed by your extensions. Defining a reasonable policy for your extension enables you to consider the resources that your extension requires and to negotiate with the browser to ensure that those are the only resources your extension has access to. These policies provide security even above the host permissions your extension requests acting as an additional layer of protection. Such policies are defined via an HTTP header or meta element. Within Chrome's extension system the extension's policy is defined via the extension's manifest.json 文件的概念，如下所示：
{
"content_security_policy": "[POLICY STRING GOES HERE]"
}
放宽内容安全策略
直到Chrome 45，没有放宽对执行内联的限制的机制JavaScript。特别是，设置包含 'unsafe-inline' 的脚本策略将无效。但是，从 Chrome 46 开始，可以通过在策略中指定源代码的 base64 编码哈希来允许内联脚本。此散列必须以使用的散列算法（sha256、sha384 或 sha512）为前缀。这可以通过将 http://* 添加到 style-src and/or script-src 来实现，如下所示：
script-src 'self' http://xxxx 'unsafe-inline' 'unsafe-eval';
and/or
style-src 'self' http://xxxx 'unsafe-inline' 'unsafe-eval';
