Express Static网络请求停留在“待定"状态. [英] Express Static network requests stuck on "pending"

问题描述

这已经工作了几个月了，我认为我没有做任何更改，但是通过 express.static ，浏览器显示"pending"(待定).无限地.

This has been working for months, I don't think I've changed anything, but with express.static, browsers show "pending" infinitely.

代码如下:

  const app = express();
  app.use('/', express.static(
    path.resolve('./build/web'),
    { dotfiles: 'allow' },
  ));

以下是Chrome的网络"标签的屏幕截图:

Here's a screenshot of Chrome's network tab:

只有 main.js 出现此问题.如果我直接打开文件，它将起作用.在Firefox中也会发生这种情况，因此我怀疑这是Node/Express问题.我关闭了adblocker.

Only main.js has this issue. If I open the file directly, it works. This also occurs in Firefox, so I suspect it's a Node/Express issue. I have adblockers turned off.

我运行了 DEBUG = *节点server.js ，输出为:

此输出对我来说似乎是正常的.

This output looks normal to me.

我尝试过:

• 清除缓存
• 隐身
• 关闭/重新打开Chrome devtools
• 关闭/重新打开Chrome
• 重新启动服务器

经过上述几次尝试后，问题消失了几个小时，但是我认为没有任何特定的措施可以持续解决问题.

After several attempts with the above, the issue goes away for a few hours, but I don't think any particular action consistently fixes the issue.

任何想法可能是罪魁祸首吗?

Any ideas what might be the culprit?

推荐答案

我在节点v14.8.0和v14.9.0上遇到了相同的问题，使用的是Express的最新发布版本以及其master分支上的最新代码.使用v12.16.2，它可以再次工作.

I encountered the same issue on node v14.8.0 and v14.9.0 with the latest published version of Express and the latest code on their master branch. Using v12.16.2 it works again.
