ruby – 使用法拉第上传文件

我在尝试使用Faraday将文件上传到Web服务时遇到问题.

我的代码：

conn = Faraday.new('http://myapi') do |f|
  f.request :multipart
end

payload = { :file => Faraday::Uploadio.new('...','image/jpeg') }

conn.post('/',payload)

尝试发布后似乎没有任何事情发生.当我检查响应this是我所看到的：

正在将正文设置为CompositeReadio对象,它似乎永远不会发送请求.

解决方法

事实证明,我需要指定一个适配器.这是最终工作的代码.

conn = Faraday.new('http://myapi') do |f|
  f.request :multipart
  f.request :url_encoded
  f.adapter :net_http # This is what ended up making it work
end

payload = { :file => Faraday::Uploadio.new('...',payload)
