Repeatedly storing JSON logs as files with Go and ensuring unique filenames
问题
作为一个新手，我正在使用Go语言，并且我从一个API中重复地接收到一个很小（约1KB）的JSON文件，它实际上是一个日志文件，我想保留每一个这样的文件。
我考虑的是将每个JSON块存储为一个唯一的文件（而不是使用数据库，这似乎是不必要的），并将它们存储在一个特定的目录中。
首先，这个想法可行吗？每天可能会有几百个文件。
更重要的是，如何确保文件名的唯一性？显然，我不能只是将每个文件保存为log.json，因为会产生冲突。我该如何确保唯一性？
英文:
A bit of a newcomer to Go, and I'm effectively receiving a small (~1KB) JSON file from an API repeatedly that is effectively a log, and I want to keep each one of these files.
I'm thinking just storing each JSON block as a unique file (in lieu of using a database, which seems unnecessary) in a specific directory.
First off, is this an okay idea? There could be potentially a few hundred per day.
More importantly, how do I ensure uniqueness across filenames? Obviously I can't just save each one as log.json and call it a day, as there would be conflicts. How would I ensure uniqueness?

无论是不是一个好主意，都可以使用ioutil.TempFile来确保你拥有唯一的文件名。TempFile会在你选择的文件前缀后附加一个保证唯一的后缀。
f, err := ioutil.TempFile(storeDirectory, fileName)
英文:
Whether it's agood idea or not is subjective, but you can use ioutil.TempFile to ensure you have unique filenames. TempFile will append a guaranteed unique suffix to the file prefix you choose.
f, err := ioutil.TempFile(storeDirectory, fileName)
