如何释放内存或删除由http.ParseMultipartForm创建的临时文件？

Question

I'm using http.ParseMultipartForm to handle file uploads at my webapp.
Documentation says:

ParseMultipartForm parses a request body as multipart/form-data. The whole request body is parsed and up to a total of maxMemory bytes of its file parts are stored in memory, with the remainder stored on disk in temporary files. ParseMultipartForm calls ParseForm if necessary. After one call to ParseMultipartForm, subsequent calls have no effect.

When the memory and/or temporary file will be deleted?

Answer 1

Everything is freed after the request is complete.

The memory buffers will be available for garbage collection, and any temporary files will be removed by the call to MultipartForm.RemoveAll() at the end of the request.
