Hi,
I would check out the Requests.jl library
<https://github.com/JuliaWeb/Requests.jl>. The following code POSTs a file
to the OCR Document API and reads the response:
Pkg.add("Requests")
using Requests
import Requests: get, post, put, delete, options
filenamne = "/path/to/file"
*response = post("http://api.havenondemand.com/1/api/sync/ocrdocument/v1";;
data=Dict("apikey"=>"YOUR_APIKEY",
"file"=>FileParam(open(filename,"r"),"text/julia","file2","file2.jl",true)))*
*readall(response)*
I work for HPE.
