当电脑使用代理后，会造成Github的clone和push等功能无法正常使用
报错内容：
PS D:\Github> git clone https://github.com/sige5193/bittly.git
Cloning into 'bittly'...
fatal: unable to access 'https://github.com/sige5193/bittly.git/': Failed to connect to github.com port 443 after 21095 ms: Couldn't connect to server
解决办法
检查本机代理
以win11为例，设置->网络和Internet->代理->手动设置代理一栏->编辑 ， 记下系统所使用代理的端口号
修改Git代理配置
7890修改为上面获取到的系统所使用代理的端口号
git config --global http.proxy http://127.0.0.1:7890
git config --global https.proxy http://127.0.0.1:7890
重新clone仓库即可
PS D:\Github> git clone https://github.com/sige5193/bittly.git
