问题描述

林建设我的第一个应用在铁轨和我想调用Flickr的API

我知道我可以使用Flickr的福，rflickr或其他宝石，但我想从头开始做我自己学习

说，例如，我想打电话给 flickr.photos.comments.getList 返回相片的意见。该参数是API_KEY和photo_id。我兼得。

我会得到响应为一个XML

 ＆LT;评论photo_id =109722179＆GT;

嗯，我不知道，我可以还给你的，一个＆LT;？/评论＆GT;
＆LT; /意见＆GT;`
 

我要存储通过调用该方法到一个变量注释我可以使用，例如访问数据，

  comments.all.first.author_name =冯丹CATT
 

或

  comments.all.first.content =嗯，我不知道，我能回去......
 

我怎样才能做到这一点？请耐心等待（遗憾的noob问题）

解决方案

 包括RubyGems的'
包括httpartyFlickr的类
  包括HTTParty  base_uriapi.flickr.com  高清self.getPhotos（UID）
    得到的回报（'/服务/ REST /'：查询=＆GT; {
      ：方法=＆GT; flickr.people.getPublicPhotos'，
      ：API_KEY =＆GT; API密钥放在这里，
      ：USER_ID =＆GT; UID}）
  结束
结束
 

，然后调用

  Flickr.getPhotos（'12345678'）
 

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

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

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.

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>`

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"

or

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

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

解决方案

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

and then call

Flickr.getPhotos('12345678')
