得到生成的令牌

应用令牌

将生成的令牌拷贝下来(不要拷贝我的，拷贝你自己生成的!)，记得保存，下次你就看不到了。

修改现有项目的url

git remote set-url origin  https://<your_token>@github.com/<USERNAME>/<REPO>.git

1
将<your_token>换成你自己得到的令牌。是你自己github的用户名，是你的项目名称，比如我的：

 git remote set-url chatroom https://ghp_95QnXXg5SBlldUXUTAr2341b3amg4HXZ1koFvj@github.com/CJ-cooper6/chatroom.git

https://你的令牌@github.com//.git

然后再执行git pull，世界又恢复原样了。

全新版本

对于全新版本，克隆的时候也在github.com前面加个令牌就好了。

git clone https://<TOKEN>@github.com/<user_name>/<repo_name>.git
