GitHub API-如何确定文件是否实际上是符号链接? [英] GitHub API - How do I find out if a file is actually a symlink?
问题描述
通过GitHub API查询符号链接时，如果符号链接指向文件而不是目录，则会得到不同的结果.后者表现得更好，因为它返回了"type":"symlink" 作为其JSON的一部分，而前者返回了"type":"file" .示例文件符号链接，示例
When querying a symlink via the GitHub API, I get different results if the symlink points to a file as opposed to a directory. The latter is more well behaved in that it returns "type": "symlink" as part of its JSON, whereas the former returns "type": "file". Example file symlink, example directory symlink.
当符号链接将自己广告宣传为文件时，这非常令人困惑，因为获取其下载URL只是获取符号链接的目标，而不是文件内容.
It's very confusing when a symlink advertises itself as a file, as GET-ing its download URL will just get you the target of the symlink and not the file contents.
如何确定文件实际上是符号链接，而不是真实文件?
How do I tell if a file is actually a symlink, as opposed to a real file?
此外，为文件符号链接返回类型"file"的行为是否是一个彻头彻尾的错误?只是看起来不正确.
Also, is the behaviour of returning type "file" for file symlinks a downright bug? It just doesn't seem right.
推荐答案
不幸的是，答案是您不要".(使用API的当前状态)无法区分文件请求和符号链接.来自文档:
The answer is unfortunately "you don't". There is no way (with the API in its current state) to differentiate between a file request and a symlink. From the documentation:
如果请求的:path指向符号链接，并且符号链接的目标是存储库中的普通文件，则API会以文件的内容进行响应[...]
If the requested :path points to a symlink, and the symlink's target is a normal file in the repository, then the API responds with the content of the file [...]
否则，API会以一个对象来描述符号链接本身:
Otherwise, the API responds with an object describing the symlink itself:
我在GitHub支持下提出了这个问题，他们确认没有办法做到这一点.他们提出要向内部团队提出要求，但我想这不太可能得到解决.
I raised this with GitHub support and they confirmed there's no way to do this. They offered to raise it as a request with the internal teams, but I would imagine it's unlikely to get picked up.
一种解决方法(并非在所有情况下都适用)是通过 https://raw来请求文件.githubusercontent.com/，如果是真实文件，则将返回文件内容，如果是符号链接，则将仅返回文件路径.
One work around (that isn't suitable in all scenarios) is to request the file via https://raw.githubusercontent.com/ which will return either the file contents if it's a real file, or just the file path if it's a symlink.
