git remote -v
wuxiao@wuxiao-C-B150M-K-Pro:~/MyGithub/DailyBlog$ git remote -v 
origin https://github.com/toyijiu/DailyBlog.git (fetch) 
origin https://github.com/toyijiu/DailyBlog.git (push)

重新设置成ssh的方式:

git remote rm origin
git remote add origin git@github.com:username/repository.git
git push -u origin master
再看下当前的传输协议: 
wuxiao@wuxiao-C-B150M-K-Pro:~/MyGithub/DailyBlog$ git remote -v 
origin git@github.com:toyijiu/DailyBlog.git (fetch) 
origin git@github.com:toyijiu/DailyBlog.git (push)
