StackOverflow This site is not a crab, but the site uses a CDN service provided by Google. So in the case of Google being a crab, the website using its CDN service will also be affected. The solution is to convert a request for a Google CDN into a domestic CDN request.
Specific practices:
Modify the Hosts file.
Mac
Open terminal (terminal), type the following command
sudo vi/etc/hosts
After typing the password, confirm (Enter);
After entering the file, click I, enter the insert mode, the Hosts file to modify;
Add the following IP and URLs below localhost (using a CDN of 360)
61.160.224.241 ajax.googleapis.com 61.160.224.241 fonts.googleapis.com 61.160.224.241 themes.googleusercontent.com 360 125.88.190.61//Zhong ke 202.141.162.123
Click ESC, exit Insert mode, enter: Wq to save and exit. At this point, the hosts modification is complete.
Next, you can access StackOverflow;)
