javascript - Puppeteer.launch 取决于操作系统

Question

是否可以根据操作系统平台设置浏览器启动的参数逻辑，如下所示:

const puppeteer = require('puppeteer');
const browserFetcher = puppeteer.createBrowserFetcher();

    (async () => {
      const platforme = await browserFetcher.platform()
      const browser = await puppeteer.launch( 
  ??? ()=>{
         if (platforme=="win64"||"win32")
      //run this params   headless: false; defaultViewport: null;
         else if (platforme=="linux")
      //run this params headless: true, args: ['--no-sandbox', '--disable-setuid-sandbox','--disable-dev-shm-usage']
     });
     const page = await browser.newPage();

如果您确实需要这种晦涩的简洁性，您可以将扩展与条件运算符一起使用:

{
  const platforme = "win64";
  const config = { ...(
    platforme === "win64" || platforme === "win32" ? { headless: false } :
    platforme === "linux" ? { headless: true } :
    {}
  ) };
  console.log(config);
}

{
  const platforme = "linux";
  const config = { ...(
    platforme === "win64" || platforme === "win32" ? { headless: false } :
    platforme === "linux" ? { headless: true } :
    {}
  ) };
  console.log(config);
}

{
  const platforme = "aix";
  const config = { ...(
    platforme === "win64" || platforme === "win32" ? { headless: false } :
    platforme === "linux" ? { headless: true } :
    {}
  ) };
  console.log(config);
}

另一种变体:

const configs = {
  win64: { headless: false },
  win32: { headless: false },
  linux: { headless: true },
}

{
  const platforme = "win64";
  const config = configs[platforme] ?? {};
  console.log(config);
}

{
  const platforme = "linux";
  const config = configs[platforme] ?? {};
  console.log(config);
}

{
  const platforme = "aix";
  const config = configs[platforme] ?? {};
  console.log(config);
}
