使用Ruby，REST获取对Twitter API的请求

Question

我尝试使用Twitter API在Ruby中学习REST。

根据https://dev.twitter.com/docs/api/1/get/trends，我必须将GET请求写入http://api.twitter.com/1/trends.json 。

我的Ruby代码是：

 require 'rubygems'
 require 'rest-client'
 require 'json'

 url = 'http://api.twitter.com/1/trends.json'
 response = RestClient.get(url)

 puts response.body

但是我遇到下一个错误：

/home/danik/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient  /abstract_response.rb:48:in `return!': 404 Resource Not Found (RestClient::ResourceNotFound)

from /home/danik/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:230:in `process_result'

from /home/danik/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:178:in `block in transmit'


from /home/danik/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/net/http.rb:745:in `start'

from /home/danik/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:172:in `transmit'

from /home/danik/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:64:in `execute'

from /home/danik/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:33:in `execute'

from /home/danik/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient.rb:68:in `get'

from TwitterTrends.rb:5:in `<main>'

怎么了？

Answer 1

您正在收到该错误，因为您尝试使用http://api.twitter.com/1/trends.json获取的资源不存在，如本文档趋势文档中所述

该方法已被弃用，并已由GET Trends /：woeid代替。 请使用新的端点更新您的应用程序。

您想要获取一个像https://api.twitter.com/1/trends/1.json这样的URL。 因此，在您的代码中，尝试执行以下操作：

 require 'rubygems'
 require 'rest-client'
 require 'json'

 url = 'https://api.twitter.com/1/trends/1.json'
 response = RestClient.get(url)

 puts response.body

您应该得到回应。
