On Gitlab, how to compare a file of two different commits
提问by yigal
回答by robertbeb
It will compare commits, you will be able to find file in list.
它将比较提交，您将能够在列表中找到文件。
- go to Repository > Compare
- paste this url: https://gitlab.com/$USER/$REPO/compare?from=$SHA1&to=$SHA2
- hit enter (notice: gitlab will set 'Source' and 'Target' properly)
- click button 'compare'
- 转到存储库 > 比较
- 粘贴这个网址：https: //gitlab.com/$USER/$REPO/compare?from=$SHA1&to=$SHA2
- 点击回车（注意：gitlab 将正确设置“源”和“目标”）
- 单击“比较”按钮

It appears the direct URL for compare is as follows
看起来比较的直接网址如下
# compare URL, where ref_source and ref_target can be commit SHA, tag, or branch
https://${gitlab_host}/${repo_path}/compare/${ref_target}...${ref_source}
# tag example 1, comparing tag v1.5.1 to master
https://${gitlab_host}/${repo_path}/compare/v1.5.1...master
# tag example 2, comparing tag v1.5.1 to tag v1.5.2
https://${gitlab_host}/${repo_path}/compare/v1.5.1...v1.5.2
# commit example 1, comparing commit SHA to master
https://${gitlab_host}/${repo_path}/compare/f6098082f...master
# commit example 2, comparing commit SHA to another commit SHA
https://${gitlab_host}/${repo_path}/compare/f6098082f...2b8daf28
To compare a single file across two commits, one needs to get a blob id of the file first, and append it to the compare url following a octothorp (#); gotta find a way to get that id though
要在两次提交中比较单个文件，首先需要获取文件的 blob id，并将其附加到比较 url 后面的 octothorp ( #) ；必须找到一种方法来获得那个 id
# compare URL, where ref_source and ref_target can be commit SHA, tag, or branch, and file_blob
https://${gitlab_host}/${repo_path}/compare/${ref_target}...${ref_source}#${file_blob}

You first need to get the sha1digest of the file path you are interested in (for instance with the sha1sumcommand). You can then build the URL to display the diff between two git ref(i.e. branch names or commit hash or tags) as follows:
您首先需要获取您感兴趣的文件路径的sha1摘要（例如使用sha1sum命令）。然后，您可以构建 URL 以显示两个git ref（即分支名称或提交哈希或标签）之间的差异，如下所示：
https://gitlab.com/<project>/-/compare/<ref1>...<ref2>#<sha1>
Here is an example with the AN/R5/L15/S2018/IDS/000/020/RUANR5L15S2018IDS20864.jsonfilename. Its sha1 is f88a5e03ecc7854e8955927af33f2ea9d090ddaf:
这是一个带有AN/R5/L15/S2018/IDS/000/020/RUANR5L15S2018IDS20864.json文件名的示例。它的 sha1 是f88a5e03ecc7854e8955927af33f2ea9d090ddaf：
$ echo -n AN/R5/L15/S2018/IDS/000/020/RUANR5L15S2018IDS20864.json | sha1sum
f88a5e03ecc7854e8955927af33f2ea9d090ddaf
Comparing it between the 878bd4f4f7edbabad3c691a7df3e317348d4ca77and 59e63f529a7fe5f28131dec36f253dca46b8ba9ccommits is done with the URL: https://git.en-root.org/tricoteuses/data.tricoteuses.fr/Agenda_XV/-/compare/59e63f529a7fe5f28131dec36f253dca46b8ba9c...878bd4f4f7edbabad3c691a7df3e317348d4ca77#f88a5e03ecc7854e8955927af33f2ea9d090ddaf
它比较之间878bd4f4f7edbabad3c691a7df3e317348d4ca77和59e63f529a7fe5f28131dec36f253dca46b8ba9c提交与URL完成：https://git.en-root.org/tricoteuses/data.tricoteuses.fr/Agenda_XV/-/compare/59e63f529a7fe5f28131dec36f253dca46b8ba9c...878bd4f4f7edbabad3c691a7df3e317348d4ca77#f88a5e03ecc7854e8955927af33f2ea9d090ddaf
The page will also display other diffs, not just the one you are interested in. But it will move you right where the diff of the file starts and you can ignore the rest.
该页面还将显示其他差异，而不仅仅是您感兴趣的差异。但它会将您移到文件差异开始的位置，您可以忽略其余的差异。
There are a few GitLab feature requeststo make it easier for the user to discover this in the future.
有一些 GitLab 功能请求可以让用户在未来更容易发现这一点。
