github 提交报403 错误解决方法

Linux环境问题出现如下：

git提交工程代码：

git push origin master

出现错误：

error: The requested URL returned error: 403 Forbidden while accessing https://github.com/username/pro.git/info/refs

fatal: HTTP request failed

两种解决问题方法：

1、修改.git/config文件中以下内容：

From: url = https://github.com/username/pro.git

To: url = https://username@github.com/username/pro.git 

or  url = https://username:password@github.com/username/pro.git 

2、直接执行命令：

git remote set-url origin https://username@github.com/username/pro.git

Linux环境下配置SSH：

1、ssh-keygen -t rsa -C "your_email@example.com"

2、ssh-agent -s

3、ssh-add ~/.ssh/id_rsa

4、修改www.github.com中SSH keys. 

5、添加~/.ssh/XX.pub内容到“Key”中，保存

6、ssh -T git@github.com 测试成功如下：

Hi username! You've successfully authenticated, but GitHub does not
# provide shell access.
