Can you please make changes to get rid of that?
I’m trying to use Faraday to upload a file to Azure Blob Storage, which has a limit (of 268435456 bytes) for the body of each request. Larger requests must be sent in chunks using a Range
or x-ms-range
header. Is there a way to do that with Faraday using multipart / FilePart or otherwise?
I looked at the implementation of FilePart
, which seems to support passing an IO
object instead of a file path, but I’m not sure if there's a way to limit such an object to just a subsection of a file?
Here is the code I’m currently using, which works fine for files below that limit:
Faraday.new(headers: {'x-ms-blob-type': 'BlockBlob'}) {|c|
c.request :multipart
c.response :raise_error
c.adapter Faraday.default_adapter
}.put(fileUploadUrl, {file: Faraday::FilePart.new(filePath, 'application/octet-stream')})
Any help would be appreciated!
I am trying to overwrite the Content-Disposition
header.
For the third party API, I need a very specific filename
that includes /
.
I noticed the Content-Disposition
header is not entirely overwritten. It still adds the default name
and filename
.
require 'faraday'
require 'faraday/multipart'
connection = Faraday.new(url: 'http://localhost:3000') do |connection_builder|
connection_builder.request :multipart
connection_builder.response :logger, nil, { headers: true, bodies: true }
end
payload = { file: Faraday::Multipart::FilePart.new('test.txt', 'text/plain', nil, 'Content-Disposition' => 'form-data; name="file"; filename="foo/bar"') }
connection.post('path', payload)
It creates
Content-Disposition: form-data; name="file"; filename="foo/bar"; name="file"; filename="test.txt"
instead of
Content-Disposition: form-data; name="file"; filename="foo/bar"
I was also trying to give the file name as a parameter to the FilePart.new
.
require 'faraday'
require 'faraday/multipart'
connection = Faraday.new(url: 'http://localhost:3000') do |connection_builder|
connection_builder.request :multipart
connection_builder.response :logger, nil, { headers: true, bodies: true }
end
payload = { file: Faraday::Multipart::FilePart.new('test.txt', 'text/plain', 'foo/bar') }
connection.post('path', payload)
It creates
Content-Disposition: form-data; name="file"; filename="bar"
while I need
Content-Disposition: form-data; name="file"; filename="foo/bar"
There are these constants which are for the use of faraday 1.x, and we've moved them around, keeping aliases around.
It could be time to release a new major, where these are removed.
Example comment:
Aliases for Faraday v1, these are all deprecated and will be removed in v2 of this middleware
I have author class using active storage.
class Author < ApplicationRecord
has_one_attached :image
end
post request
require 'faraday'
require 'faraday/multipart'
payload = { author: {title: "lo"} }
payload[:author][:image] = Faraday::Multipart::FilePart.new(File.open(Rails.root.join('app', 'assets', 'images', 'about.jpg')), 'image/jpeg')
conn.post('/api/v1/authors', payload.to_json)
My received params
#<ActionController::Parameters {"author"=>{"title"=>"lo"}, "image"=>{"content_type"=>"image/jpeg",
"original_filename"=>"local.path", "local_path"=>"local.path",
"io"=>"/home/kashif/ticket_plot_api/app/assets/images/about.jpg", "opts"=>{}}, "controller"=>"api/v1/authors",
"action"=>"create"} permitted: false>
Author is saving without image
Is anything wrong?
Thanks
The 2.2.0 was just released, and we should use that, avoiding deprecation warnings (it changed its file structure to something better; if we use the existing structure, it works but we get warnings).
