Error: Evaluation failed: ReferenceError: _0x5b9d0e is not d

Question

我可以成功运行下面的代码，但在混淆javascript-obfuscator后失败。

const puppeteer = require('puppeteer-core');
let params = {
ignoreHTTPSErrors: true,
args: [
'--ignore-certificate-errors',
'--no-sandbox',
],
executablePath: this.chromePath,
headless: true,
};
const browser = await puppeteer.launch(params);
var page = await browser.newPage();
await page.goto(this.url, { waitUntil: 'load' });
await page.waitForTimeout(2000);
await page.content();       ----------------------- error in this line
await page.setViewport({ width: 1600, height: 1200 });
await page.waitForTimeout(2000);

错误信息:

这个问题的原因是什么，如何解决这个问题。任何建议吗?

有两种解决方案:

首先，你可以从外部传递变量，像这样:

形象另一种是将stringArray: true禁用为stringArray: false。

CLI命令:

javascript-obfuscator ./app.js --output ./app-obfuscated.js --string-array false

我认为这是javascript-obfuscator库的bug。作为替代方案，您可以使用以下包:

js-obfuscator

和木偶师配合得很好。
