内容安全策略 （CSP）

CSP 是通过头部或元标签实施的安全策略，用以规范和授权在您的网站上加载的内容。

要建立一个 CSP 指令参考，您可以选择在服务器上配置 HTTP 响应头，或者在 HTML 头元素中设置元标签。

通过这样做，您可以创建一套规则，以决定哪些内容是被允许或禁止的。这些规则增强了您网站对内容注入和跨站脚本（XSS）攻击的安全性。

作为一个嵌入式控件，SpreadJS 必须遵守 CSP 指南，确保代码远离任何潜在的攻击点。因此，包括一些特定规则来增加 SpreadJS 的安全性，如下所述。

// No Eval rule in TSLINT
eval("alert('XSS!')");

// No Implied Eval rule in TSLINT
setTimeout("alert('Hi!');", 100);
setInterval("alert('Hi!');", 100);
execScript("alert('Hi!')");
window.setTimeout("count = 5", 10);
window.setInterval("foo = bar", 10);

// No New Function rule in TSLINT
new Function("alert('XSS!')")();

请注意，导入和导出 API 使用 Web Worker 来压缩或解压文件，用户必须设置正确的 CSP 规则以避免错误。

例如，考虑以下 CSP 规则：

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

这个 CSP 规则允许从相同的源加载 Web Worker，并使用 blob URIs 用于 Web Worker，其中：

  • worker-src 'self': 限制web workers的加载，只能来自于文档相同的源

  • blob:: 允许使用blob URIs用于web workers

  • 'unsafe-inline': 允许执行内联脚本

  • 'unsafe-eval': 允许使用eval()及类似的JavaScript函数，这些函数执行作为字符串传递的代码

  • data:: 允许使用数据URIs
