Ruby post a file stream via HTTP as multipart/form-data?

Question

Now,I have a need that post a file stream,not a local file.the process is:

client(file) ---> my server ----> third party Cloud Storage,the transfer is file stream. I have found this article: Ruby: How to post a file via HTTP as multipart/form-data?

require 'rest_client'
RestClient.post('http://localhost:3000/foo', 
:name_of_file_param => File.new('/path/to/file'))

you can see that the name_of_file_param is a local file,not stream.

so I want to know ,if this is file stream form the client ,what should I do

您应该能够使用任何IO对象（包括流）作为参数：

RestClient.post('http://localhost:3000/foo', :name_of_file_param => my_stream)
