问题：
cch:requsetDatas leo$ git push origin master
remote: Permission to bbb/requsetDatas.git denied to aaa.
fatal: unable to access 'https://github.com/bbb/requsetDatas.git/': The requested URL returned error: 403
解决方法：
1：终端输入：vim .git/config 就是打开git的config配置文件。
2：找到下面一句
[remote "origin"]
url = https://github.com/bbb/example.git
修改为：
[remote "origin"]
url = https://bbb@github.com/bbb/example.git
保存并退出。(注意颜色字体)
3：再次git push origin master，提示输入密码，OK。
