# github 踩雷紀錄 https to ssh

想說來練習下git吧
怎麼用個github一堆問題
後來想到
噢對，今年七月全面使用ssh key了
https禁用
所以我一開始抄的url就不能用了
但指示不清不楚的阿...
只有我在git push時會說git name錯誤


參考過程:
先在網站上開一個new reposity
複製上面提示的網址url
到git bash
指定到哪個資料夾 cd
`git clone https://github.com/myaccount/HelloREADME.git`

後來push失敗
而且會跳出輸入視窗要我輸入帳號密碼
但不管輸入幾次都是錯的

想到喔對要改用SSH
所以照著指示去generate SSH key
`ssh-keygen -t ed25519 -C "[e-mail]"`
//用ed25519加密的意思

到github網站上setting處把pubkey內容貼上去
照著教學走~

重點來了
有個東西叫做ssh-agent
要先打開
我後來用git bash這程式直接用

$ eval "$(ssh-agent -s)"
Agent pid 2031

將ssh key加入agent

$ ssh-add ~/.ssh/id_ed25519
Identity added: /c/Users/mat/.ssh/id_ed25519 ([e-mail])

忘記開ssh-agent的話會出現

$ ssh-add ~/.ssh/id_ed25519
Could not open a connection to your authentication agent.

接著應該可以直接git push了吧?!

$ git push
fatal: The upstream branch of your current branch does not match
the name of your current branch.  To push to the upstream branch
on the remote, use

    git push origin HEAD:master

To push to the branch of the same name on the remote, use
     git push origin HEAD 
To choose either option permanently, see push.default in 'git help config'.

沒有...這什麼指示?

後來查原來https跟ssh git name不一樣
一個是:，一個是/
所以阿~不能混用阿(遠目
後來將remote改掉就可以了

`$ git remote set-url origin [e-mail]:[e-mail]:myaccount/myaccount.git`

reference:
1. If it is asking you for a username and password, your origin remote is pointing at the HTTPS URL rather than the SSH URL.https://stackoverflow.com/questions/14762034/push-to-github-without-a-password-using-ssh-key
2. 官方的指引:https://docs.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh
3. 複製ssh-key金鑰到github網站上:https://blog.jaycetyle.com/2018/02/github-ssh/
4. 只有說全面改用ssh-key但沒講很清楚怎麼做的官方文件:https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/
