如何在 Ruby on Rails 中调用 API(例如 Flickr API)?新手问题

问题描述

我正在用 Rails 构建我的第一个应用程序，我想调用 Flickr 的 API

Im building my first app in rails and I would like to call Flickr's API

我知道我可以使用 flickr-fu、rflickr 或其他 gem，但我想自己从头开始学习

I know I can use flickr-fu, rflickr or other gem but I want to do it myself from scratch to learn

例如，我想调用返回照片评论的 flickr.photos.comments.getList.参数是 api_key 和 photo_id.我两个都有.

Say, for example, I want to call flickr.photos.comments.getList that returns the comments for a photo. The arguments are api_key and photo_id. I have both.

我将得到一个 xml 格式的响应

I will get the response as an xml

<comments photo_id="109722179">
<comment id="6065-109722179-72057594077818641" author="35468159852@N01" authorname="Rev Dan Catt" datecreate="1141841470" permalink="http://www.flickr.com/photos/straup/109722179/#comment72057594077818641">
Umm, I'm not sure, can I get back to you on that one?</comment>
</comments>`

我想将通过调用该方法接收到的数据存储到一个变量 comments 中，我可以使用例如

I want to store the data received by calling that method into a variable comments that I can access the data using, for example,

comments.all.first.author_name = "Rev Dan Catt"

或

comments.all.first.content = "Umm, I'm not sure, can I get back to..."

我该怎么做?请耐心等待(抱歉菜鸟问题)

How can I do this? Please be patient (sorry for the noob question)

推荐答案

include 'rubygems'
include 'httparty'

class Flickr
  include HTTParty

  base_uri 'api.flickr.com'

  def self.getPhotos(uid)
    return get('/services/rest/', :query => {
      :method => 'flickr.people.getPublicPhotos',
      :api_key => 'api key goes here',
      :user_id => uid})
  end
end

然后调用

Flickr.getPhotos('12345678')
