问题描述

我可以使用回形针将图像附件上传到我的应用程序.但我想通过法拉第连接将图像发送到另一个应用程序.其他属性已成功发送，但不是附件图像.我不确定我应该怎么做才能实现这一目标.

I am able to upload image attachements using paperclip to my application. But I would like to send the image to another application via faraday connection. Other attributes are successfully sent but not the attachment image. I am not sure what I should do to achieve this.

推荐答案

您需要使用可以创建多部分 Post 请求的 HTTP 库.

You need to use an HTTP library that can create Multipart Post requests.

例如 Typhoeus 可以上传文件:https://github.com/typhoeus/typhoeus#handling-file-uploads.

For example Typhoeus can do file uploads: https://github.com/typhoeus/typhoeus#handling-file-uploads.

还有 Net::HTTP Multipart Post:https://github.com/nicksieger/multipart-发帖

There's also Net::HTTP Multipart Post: https://github.com/nicksieger/multipart-post

最后:https://github.com/jwagener/httmultiparty

阅读这些 gem 的自述文件，它们都使上传文件变得同样容易.我喜欢 Typhoeus，因为它可以执行并行请求.另外两个更简单，但同样有用.

Read the READMEs to any of those gems, they all make it equally easy to do file uploads. I like Typhoeus because it can do parallel requests. The other two are a bit simpler but equally useful.
