方法一：修改Host
在DNS查询网站（例如）中查询github.com、github.global.ssl.fastly.net，记录ip地址
（一般直接去raw.hellogithub.com/hosts中获取，复制粘贴即可）
- Hosts文件所在位置
Mac（苹果电脑）系统hosts位于 /etc/
Linux系统hosts位于 /etc/
Windows 系统位于 C:\Windows\System32\drivers\etc\
- 文件的最后添加
记录的ip github.com
记录的ip github.global.ssl.fastly.net
- 刷新dns缓存
windows输入：ipconfig /flushdns
Linux输入：sudo rcnscd restart
Mac OS X终端输入：sudo killall -HUP mDNSResponder
windows用户的同学可直接运行下面的python脚本即可实现GitHub的正常访问
import ctypes
import sys
def is_admin():
try:
return ctypes.windll.shell32.IsUserAnAdmin()
except:
return False
if is_admin():
import requests
from time import sleep
import os
import datetime
r = requests.get("https://raw.hellogithub.com/hosts")
now = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
content = f"""

# space.
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.

"""
with open('C:\Windows\System32\drivers\etc\hosts', 'w+') as f:
f.write(content)
f.close()
dnsFlush = "ipconfig /flushdns"
os.system(dnsFlush)
print("github DNS刷新成功")
sleep(3)
else:
# Re-run the program with admin rights
ctypes.windll.shell32.ShellExecuteW(
None, "runas", sys.executable, __file__, None, 1)
说明
只能对针对DNS污染 ip会变化，所以需要进行更换 要查询的域名其实不止那两个，只是两个例子，配置之后可以正常打开github，剩下要改的可以去自行了解，当然raw.hellogithub.com/hosts中给出的是全的
方法二：设置代理
1. 代理软件内设置
- 在代理软件内勾选
允许来自局域网的连接 - 记下端口号（例如：1080）
- 开启
全局模式
2. 给 Git 全局配置代理
# 配置http代理
git config --global http.proxy http://127.0.0.1:【端口号】
git config --global https.proxy https://127.0.0.1:【端口号】
# 例如：git config --global http.proxy http://127.0.0.1:10808
# git config --global https.proxy https://127.0.0.1:10808
# 配置socks5代理
git config --global http.proxy socks5://127.0.0.1:【端口号】
git config --global https.proxy socks5://127.0.0.1:【端口号】
# 如果只对 Github 进行代理，对国内的仓库不影响，例如gitee
git config --global http.https://github.com.proxy https://127.0.0.1:【端口号】
git config --global https.https://github.com.proxy https://127.0.0.1:【端口号】
# 只对 GitLab 进行代理，对国内的仓库不影响
git config --global https.https://https://gitlab.com.proxy https://127.0.0.1:1080
查看配置文件的路径
git config –list –show-origin
恢复
如果不想用代理，可以用以下的方法恢复：
git config --global --unset http.proxygit config --global --unset https.proxy
