看了好多帖子，终于在混乱中找到自己适合的方法。。。。。。
自我感觉这个比较简单。
先安装本地git，官方下载地址：http://git-scm.com/download/ 根据你自己的系统 下载对应版本。
Administrator@USER-20170816VX MINGW64 /g/project/10guang （桌面要提交的文件，右键选择git bash here）
$ git clone https://github.com/gaobing1252/web-app.git （使用仓库地址生成 web-app 目录，这个目录是在提交文件的里面，然后把文件里面要上传的内容都拷贝到生成的web-app下）
Cloning into 'web-app'...
warning: You appear to have cloned an empty repository.
Administrator@USER-20170816VX MINGW64 /g/project/10guang
$ cd web-app （继续命令到web-app，从此处开始）
Administrator@USER-20170816VX MINGW64 /g/project/10guang/web-app (master)
$ git add . （注意这个 点 前面有空格的！）

$ git remote add origin git@github.com:gaobing1252/web-app.git （origin 后面的地址是 ssh类型的，不是htttps！）
fatal: remote origin already exists.

$ git push -u origin master

* [new branch] master -> master
Branch 'master' set up to track remote branch 'master' from 'origin'.（成功！）
这个每次上传都要输入账号密码，还有另一种绑定秘钥的。可我生成了几次也没成功。。。。
感觉输入账号密码也不麻烦。
