Chrome扩展中Tesseract.js无法正常运行的问题求助

我正在开发一款Chrome扩展，想用Tesseract.js实现图片文字识别的功能，但遇到了个头疼的问题：Tesseract.js默认会在运行时从CDN加载worker.min.js，可Chrome的内容安全策略（CSP）禁止加载外部脚本。我把自己的manifest.json贴出来，也说说试过的几种解决方法，但全都没起作用，希望大家能帮忙看看。

我试过的几种方案 #

• 尝试改用本地的worker脚本，代码如下，但依然不行——因为本地脚本是通过extension://app_id/worker.min.js路径加载的，还是触发了CSP限制
• 调整了extension_pages里的CSP规则，试着添加blob:和'wasm-unsafe-eval'这两个选项，结果问题还是没解决

尝试的代码示例 #

// 尝试用本地脚本初始化Worker
const worker = Tesseract.createWorker({
  workerPath: chrome.runtime.getURL('assets/worker.min.js'),
  corePath: chrome.runtime.getURL('assets/tesseract-core.wasm.js'),
  langPath: chrome.runtime.getURL('assets/lang/')
});

// 尝试用Blob URL加载本地Worker脚本
const worker = Tesseract.createWorker({
  workerPath: blobURL,
  corePath: chrome.runtime.getURL('tesseract-core.wasm.js'),
  langPath: chrome.runtime.getURL('lang/')
});
