检查用户.SSH目录

若存在则直接使用已生成的ssh公私密钥，跳过生成SSH公私密钥步骤

若需要免密提交则要保证生成的ssh公私密钥是未输入密码的

打开.ssh目录下的id_rsa.pub文件，复制里面的内容，到github和gitee设置中找到的SSH key的信息，添加即可。

C:\Users\tanxz\.ssh> ssh -T git@github.com
Hi tanxinzheng! You've successfully authenticated, but GitHub does not provide shell access.
PS C:\Users\tanxz\.ssh> ssh -T git@gitee.com
Hi tanxinzheng! You've successfully authenticated, but GITEE.COM does not provide shell access.

若显示以上信息，恭喜你以后终于不用输入密码了！！：）
