如何通过 ActiveResource / REST API 将文件上传到 Redmine？

Question

我正在尝试将图像批量上传到 Redmine 并将它们各自链接到特定的 wiki 页面。

文档（Rest_api、Using the REST API with Ruby）提到了一些方面，但示例以各种方式失败。我还尝试从source 中获得想法——但没有成功。

谁能提供一个简短的示例来说明如何从 Ruby 中上传和链接图像？

这有点棘手，因为附件和 wiki API 都相对较新，但我过去做过类似的事情。这是使用rest-client 的最小工作示例：

require 'rest_client'
require 'json'

key = '5daf2e447336bad7ed3993a6ebde8310ffa263bf'
upload_url = "http://localhost:3000/uploads.json?key=#{key}"
wiki_url = "http://localhost:3000/projects/some_project/wiki/some_wiki.json?key=#{key}"
img = File.new('/some/image.png')

# First we upload the image to get attachment token
response = RestClient.post(upload_url, img, {
  :multipart => true,
  :content_type => 'application/octet-stream'
})
token = JSON.parse(response)['upload']['token']

# Redmine will throw validation errors if you do not
# send a wiki content when attaching the image. So
# we just get the current content and send that
wiki_text = JSON.parse(RestClient.get(wiki_url))['wiki_page']['text']

response = RestClient.put(wiki_url, {
  :attachments => {
    :attachment1 => { # the hash key gets thrown away - name doesn't matter
      :token => token,
      :filename => 'image.png',
      :description => 'Awesome!' # optional
    }
  },
  :wiki_page => {
    :text => wiki_text # original wiki text
  }
})
