用Git将本地文件push到远程github网站的过程中踩的坑

之前一直把代码存在D盘里，结果D盘突然坏了，导致代码丢失。痛定思痛，决定及时将本地代码同步到github上。
本文的操作步骤参考使用Git将本地文件提交到远程仓库，详情请点击链接，本文只记录一些坑。

简要的操作步骤如下：（注：命令行操作都在Git bash中进行。）

git init # 1.将项目文件夹初始化为git仓库gitadd.# 2.把文件添加到暂存区git commit -m 'first commit'# 3.把文件提交到仓库，引号内为说明内容git remote add origin 你的远程库地址 # 4.关联到远程库git pull --rebase origin master # 5.获取远程库与本地同步合并git push -u origin master # 6.把本地库的内容推送到远程

1.fatal: couldn’t find remote ref master

$ git pull --rebase origin master
fatal: couldn't find remote ref master

解决办法：执行以下命令

$ git pull --rebase origin main

2.Merge conflict

$ git pull --rebase origin main
From https://github.com/xxx/xxx
 * branch            main       -> FETCH_HEAD
Auto-merging README.md
CONFLICT (add/add): Merge conflict in README.md
error: could not apply 67749e6... first commit

解决办法：删除冲突文件

$ gitrm README.md
rm'README.md'

3.OpenSSL SSL_read: Connection was reset, errno 10054

$ git push -u origin master
fatal: unable to access 'https://github.com/xxx/xxx.git/': OpenSSL SSL_read: Connection was reset, errno 10054

解决办法：执行以下命令

$ git config --global http.sslVerify "false"

4.Failed to connect to github.com port 443:connection timed out
解决办法：执行以下命令

git config --global http.proxy http://127.0.0.1:1080
git config --global https.proxy http://127.0.0.1:1080
git config --global --unset http.proxy
git config --global --unset https.proxy

5.The requested URL returned error: 403

$ git push -u origin master
warning: ----------------- SECURITY WARNING ----------------
warning: | TLS certificate verification has been disabled!|
warning: ---------------------------------------------------
warning: HTTPS connections may not be secure. See https://aka.ms/gcm/tlsverify formore information.
remote: Permission to xxx/xxx.git denied to xxx.
fatal: unable to access 'https://github.com/xxx/xxx.git/': The requested URL returned error: 403

解决办法：
网上一般方法是更改windows用户凭据git使用git push 命令跳出remote: Permission to A denied to B的问题。
但是我没有看到github凭据，后来发现问题出在第四步关联到远程库，远程库的网址应选择SSH而不是HTTPS。
如果填错了地址，更改方法为：

$ git remote rm origin
$ git remote add origin [email protected]:xxx.git

！注意：如果反复出现10054、443和403error，首先检查是否在Git bash里面操作，然后检查远程库的地址。

6.fatal: Could not read from remote repository.

$ git push -u origin master
The authenticity of host'github.com (140.82.112.3)' can't be established.
ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

解决办法：这是因为github没有设置SSH公钥，按照教程操作即可。
