不知道有没有人跟我一样，更新Chrome到最新版后，在$$的PAC模式下，Chrome怎么都无法访问Google搜索。原以为是深度的锅，只能将就着先用Firefox。查了一段时间，终于找到解决办法。
似乎是72+版本后，Chrome作了一些变更引起的。解决办法是：
地址栏输入：chrome://flags
然后找到Enable network service选项，设置为Disabled即可。

Hope this help you!

chromium移除了对pac 的 file协议的支持，但是chromium bug一共给出了几种办法

Let me start by summarizing the issue.

When Chrome is run with NetworkService enabled (which is currently being experimented with on Stable channel), there isn't support for PAC scripts using the file://, so configurations using them will fail to fetch the PAC script and default to DIRECT connections.

Current mitigations include:

(1) Launch with --disable-features=NetworkService

(2) Run a local HTTP server, and then point to the PAC file as http://localhost/... rather than file://...
For instance:
$ python -m SimpleHTTPServer 8000
$ google-chrome --proxy-pac-url="http://localhost:8000/script.js"

(3) Use a Chrome extension to manage your PAC file instead of using a file:// URL.

(4) Convert the file:// URL to a data: URL
For instance:
$ google-chrome --proxy-pac-url='data:application/*-config;base64,'$(base64 -w0 /path/to/pac/script)

The histogram data (Net.ProxyResolutionService.PacUrlScheme) for frequency of file:// URL based PAC scripts on Stable channel:

  * Windows: 0.7%
  * macOS / Linux: 1.5% // 倒霉的多是linux用户？？？？
  * ChromeOS / Android: 0%
