英文:
golang git - Is there a way to pull latest from remote branch if the repo is already cloned rather than cloning it again
问题
我有一个需要每天克隆的存储库，用于获取一些数据。在使用go-git库的golang中，是否有一种方法只克隆一次存储库，并使用git pull更新存储库呢？
英文:
I have a repo which needs to be cloned daily for some data. Is there a way in golang using go-git library to clone the repo only once and update the repo using git pull?

当然，有一个Worktree.Pull()方法可以实现这个功能。
// 打开已经克隆的仓库路径
r, err := git.PlainOpen(path)
// 获取工作目录
w, err := r.Worktree()
// 从远程仓库拉取
err = w.Pull(&git.PullOptions{RemoteName: "origin"})
（为了更好的可读性，省略了错误检查）
英文:
Sure, there's Worktree.Pull() method exactly for that.
// Open already cloned repo in path
r, err := git.PlainOpen(path)
// Get the working directory
w, err := r.Worktree()
// Pull from origin
err = w.Pull(&git.PullOptions{RemoteName: "origin"})
