Permission denied (publickey). fatal: The remote end hung up unexpectedly while pushing back to git

配置完git ssh后

ssh -T git@github.com 返回正常结果

Hi ＊＊＊＊! You've successfully authenticated, but GitHub does not provide shell access

但是在push 的时候出现 如下错误

Permission
denied (publickey). fatal: The remote end hung up unexpectedly while pushing back to git repository [duplicate]

解决方法：
.git/config文件将
url = https://@github.com/linglongwang/Demo.git
改为
url = https://username@github.com/linglongwang/Demo.git
再 git push 成功！
