一：将本地的代码push到一个干净的服务器仓库中
git init
git add *
git commit -m "initialized"
把仓库推送到服务器
git push origin master
git push http://192.168.0.172:9080/gp_iot/project_iot.git
fatal: The current branch master has no upstream branch.
To push the current branch and set the remote as upstream, use
git push --set-upstream http://192.168.0.172:9080/gp_iot/project_iot.git master
二： clone master分支代码：（下面的两条命令都正确）
git clone http://192.168.0.172:9080/gp_iot/project_iot.git
git clone http://192.168.0.172:9080/gp_iot/project_iot.git master
三： clone develp分支代码：
错误用法：（clone下来的还是master，不是develp）
git clone http://192.168.0.172:9080/gp_iot/project_iot.git develop
正确：
先： git clone http://192.168.0.172:9080/gp_iot/project_iot.git
再到clone下来后的目录内执行命令：
git checkout -b develop origin/develop
再看代码就是分支的代码了。
git init
git add *
git commit -m "initialized"
git push --set-upstream 仓库地址 master
git branch develop
git branch
git checkout develop
git push 仓库地址 develop:develop
