获取文件上次从 Github 存储库更新的时间

Question

我可以通过 using the GitHub v3 API. 获取文件内容（如果是文件夹，我可以获取文件列表）示例：

https://api.github.com/repos/[Owner]/[Repository]/contents/[Folder]

但是我怎么知道文件上次更新的时间？有 API 吗？

Answer 1

考虑到 git 不会 store file timestamps (and other metadata like permissions and ownership), for reasons I detailed here。

因此远程存储库端（此处 GitHub）也不存在该信息。

Answer 2

如果你知道确切的文件路径，你可以使用 list commits on repository API 指定一个 path，它只包括具有这个特定文件路径的提交，然后提取最近的提交（最近的是第一个）：

使用 Rest API v3

https://api.github.com/repos/bertrandmartel/speed-test-lib/commits?path=jspeedtest%2Fbuild.gradle&page=1&per_page=1

使用curl & jq：

curl -s "https://api.github.com/repos/bertrandmartel/speed-test-lib/commits?path=jspeedtest%2Fbuild.gradle&page=1&per_page=1" | \
     jq -r '.[0].commit.committer.date'

使用 GraphqQL API v4

{
  repository(owner: "bertrandmartel", name: "speed-test-lib") {
    ref(qualifiedName: "refs/heads/master") {
      target {
        ... on Commit {
          history(first: 1, path: "jspeedtest/build.gradle") {
            edges {
              node {
                committedDate
              }
            }
          }
        }
      }
    }
  }
}

Try it in the explorer

使用curl & jq：

curl -s -H "Authorization: Bearer YOUR_TOKEN" \
     -H  "Content-Type:application/json" \
     -d '{ 
          "query": "{ repository(owner: \"bertrandmartel\", name: \"speed-test-lib\") { ref(qualifiedName: \"refs/heads/master\") { target { ... on Commit { history(first: 1, path: \"jspeedtest/build.gradle\") { edges { node { committedDate } } } } } } } }"
         }' https://api.github.com/graphql | \
     jq -r '.data.repository.ref.target.history.edges[0].node.committedDate'

Answer 3

您实际上可以使用您特别提到的请求来确定您想要什么。

请注意，以下所有 dates/times 均采用 GMT（当然）。

Copy & paste the following command to find the last modified date and time of Folder/File in repository ForStackExchange by user YenForYang:
\curl -sIA. --ignore-content-length  \
     -H"If-Modified-Since: Sun May 01 00:00:00 9999" \
     "https://api.github.com/repos/YenForYang/ForStackExchange/contents/Folder/File?ref=branch" \
| \grep -m1 -oP "(?<=Last-Modified: )[ADFJMNOSTWa-eghilnoprtuvy0-9:, ]{25}" \
(If Perl regex isn't available, you can ... | grep -F -m1 "Last-Modified:")

The above command should return (GMT): Thu, 27 Dec 2018 11:01:26 (or later, if I update the file for some reason)

注意，如果ref参数未指定，ref=master.

如果您不会复制和粘贴，并且不关心 API 速率限制，您可能会选择较短的：

\curl -sIL "api.github.com/repos/yenforyang/forstackexchange/contents/Folder/File?ref=branch" | \grep "^Las"

如果你在 Windows 上没有 grep，只需使用 find "Last-Modified: "（需要双引号）。

如果您在 Windows 上没有 curl（下载...或）使用 Powershell

(iwr -me HEAD -usebasic "https://api.github.com/repos/yenforyang/forstackexchange/contents/Folder/File?ref=branch").Headers."Last-Modified"

使用Python

pip 安装 PyGithub

from github import Github
g = Github()
repo = g.get_repo("datasets/population")
print(repo.name)
commits = repo.get_commits(path='data/population.csv')
print(commits.totalCount)
if commits.totalCount:
    print(commits[0].commit.committer.date)

输出：

population
