Ruby:如何通过 HTTP 将文件作为 multipart/form-data 发布? [英] Ruby: How to post a file via HTTP as multipart/form-data?

问题描述

我想做一个 HTTP POST，它看起来像从浏览器发布的 HMTL 表单.具体来说，发布一些文本字段和一个文件字段.

I want to do an HTTP POST that looks like an HMTL form posted from a browser. Specifically, post some text fields and a file field.

发布文本字段很简单，net/http rdocs 中有一个示例，但我不知道如何发布文件.

Posting text fields is straightforward, there's an example right there in the net/http rdocs, but I can't figure out how to post a file along with it.

Net::HTTP 看起来不是最好的主意.curb 看起来不错.

Net::HTTP doesn't look like the best idea. curb is looking good.

推荐答案

我喜欢 RestClient.它用多部分表单数据等很酷的功能封装了 net/http:

I like RestClient. It encapsulates net/http with cool features like multipart form data:

require 'rest_client'
RestClient.post('http://localhost:3000/foo', 
  :name_of_file_param => File.new('/path/to/file'))

它还支持流式传输.

gem install rest-client 会让你开始.
