概述

github以及gitlab是大部分开发者都在使用的仓库管理工具。笔者在使用的过程中收集了一些之前遇到的问题，并撰写了该文章，以后有更新的会不定期在文章后添加。

git clone无权限

拉取公司项目的仓库，发现拉取失败：

git clone git@git.corp.xxx.cn:ios/Evian.git
Cloning into 'Evian'...
git@git.corp.imdada.cn: Permission denied (publickey).
fatal: Could not read from remote repository.

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

通过如下几步解决该问题：
第一步：选中个人配置

第二步：选中SSH Keys，并输入SSH Key

那么 SSH Key怎么生成呢，可以通过如下命令：

ssh-keygen

笔者的操作流程如下：

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/kyson/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/kyson/.ssh/id_rsa.
Your public key has been saved in /Users/kyson/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:k/QfKoFlBR1tJiAnzd25kJPe2ES3soeUhGZOktQ41ow kyson@kysondeMacBook-Air.local
The key's randomart image is:
+---[RSA 2048]----+

git push无权限

remote: Permission to zjh171/GCDAsyncSocket.git denied to AngryLi.
fatal: unable to access 'https://github.com/zjh171/GCDAsyncSocket.git/': The requested URL returned error: 403

进入.git文件夹，找到config文件（.git文件夹是隐藏文件夹，位于当前项目的根目录下）：

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
    ignorecase = true
    precomposeunicode = true
[remote "origin"]
    url = https://github.com/zjh171/GCDAsyncSocket.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master

中的

    url = https://github.com/zjh171/GCDAsyncSocket.git

修改为：

    url = https://zjh171@github.com/zjh171/GCDAsyncSocket.git

即可

Pushing to Git returning Error Code 403 fatal: HTTP request failed

解决方式：
Github seems only supports ssh way to read&write the repo, although https way also displayed 'Read&Write'.

So you need to change your repo config on your PC to ssh way:

edit .git/config file under your repo directory
find url=entry under section [remote "origin"]
change it from url=https://MichaelDrogalis@github.com/derekerdmann/lunch_call.git to url=ssh://git@github.com/derekerdmann/lunch_call.git. that is, change all the texts before @ symbol to ssh://git
Save config file and quit. now you could use git push origin master to sync your repo on GitHub
