最近用git下载一个开源项目的时候，出现了这样的错误信息：
SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed while accessing https://github.com/...
出现这样的情况是因为git clone默认采用SSL认证的时候，本地找不到对应证书，所以可以通过关掉验证来解决这一问题，就是在git clone命令前面加上：
env GIT_SSL_NO_VERIFY=true
所以完整的命令是这样：
env GIT_SSL_NO_VERIFY=true git clone https://github.com/...
wget -c -O out.zip "http://blog.is36.com/abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz.abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz.zip"
把下载的文件输出为一个固定的文件名，比如：out.zip
