I’m looking for standard function which can parse body from multipart request. I received json and csv in one multipart request. How can I parse it?
Following example is received in one multipart request. Body received from request converted to string:
```julia
-----------------------------2469282126307371221439455
Content-Disposition: form-data; name="configuration"
Content-Type: application/csv
{
"attribute1": "value1",
"attribute2": "value2",
"attribute3": "value3"
}
-----------------------------2469282126307371221439455
Content-Disposition: form-data; name="file"; filename="Vieden.csv"
Content-Type: text/csv
date;value1;value2
2004-01-01 00:00:00;8;2
2004-01-01 01:00:00;7;5
2004-01-01 02:00:00;2;4
-----------------------------2469282126307371221439455--

Call `HTTP.parse_multipart_form` on the content. That should parse it into an array so you can get the name, contenttype, filename, and data.

Thank you so much for your advice. It looks it will work, but I’ve been not able to read content of this multipart array. How can I do that? How can I get data of multipart?
I tried following:
```julia
println(HTTP.parse_multipart_form(req)[2].data)
```
```julia
┌ Error: error handling request
│ exception =
│ ArgumentError: ensureroom failed, IOBuffer is not writeable
│ Stacktrace:
│ [1] ensureroom_slowpath(::Base.GenericIOBuffer{SubArray{UInt8,1,Array{UInt8,1},Tuple{UnitRange{Int64}},true}}, ::UInt64) at ./iobuffer.jl:303
│ [2] ensureroom at ./iobuffer.jl:325 [inlined]
│ [3] write at ./iobuffer.jl:446 [inlined]
```
Another output was:
```julia
println(HTTP.parse_multipart_form(req))
```
```julia
HTTP.Multipart[
HTTP.Multipart(data=::Base.GenericIOBuffer{
SubArray{UInt8,1,Array{UInt8,1},
Tuple{UnitRange{Int64}},true}},
contenttype="text/plain",
contenttransferencoding="")),
HTTP.Multipart(filename="File.csv",
data=::Base.GenericIOBuffer{SubArray{UInt8,1,Array{UInt8,1},
Tuple{UnitRange{Int64}},true}},
contenttype="text/csv", contenttransferencoding=""))
]
```

Again, thank you very much. It is elegant solution. Finally, you can ignore previous message, I solved it:
```julia
println(String(read(HTTP.parse_multipart_form(req)[2].data)))
```
