git release功能

命令行：

git tag -a v3. -m "这是4.0版本"
git push origin v3.
//git tag -a 标签名称 -m "说明"
//git push origin 标签名称

删除tag

git tag -d v1.  //删除本地tag

git push origin :v1.//删除远程tag
//也可以这样
git push origin --delete tag V1. 

以上命令在项目仓库创建了一个v3.0的release，如下图：

1.进入到项目仓库，选择release选项卡，可以点击create a new release/Draft a new release创建一个新的release.

2.未勾选This is a pre-release通过github官方提供的api可访问我们的release信息，格式如下：

/repos/:owner/:repo/releases/:id
