Question

我尝试使用twitter api和ruby进行精确搜索。但由于新的twitter api，我无法访问json文件。

这是链接 https://api.twitter.com/1.1/search/tweets.json?q=%23superbowl&result_type=recent

请告诉我如何获取json文件。

我已经发布了我的rb文件，plz help

#load 'twitter_config.rb'
#Create seprate config file.

request_query = ''
url = "#{request_uri}#{phrase_value}"
url.gsub!(' ','%20')
print url;

# Actually fetch the contents of the remote URL as a String.
buffer = open(url).read

# Convert the String response into a plain old Ruby array. It is faster and saves you time compared to the standard Ruby libraries too.
result = JSON.parse(buffer)
# An example of how to take a random sample of elements from an array. Pass the number of elements you want into .sample() method. It's probably a better idea for the server to limit the results before sending, but you can use basic Ruby skills to trim & modify the data however you'd like.
result = result.sample(5)

# Loop through each of the elements in the 'result' Array & print some of their attributes.
 result.each do |tweet|
  puts "Count       Username                tweet"           
  puts "(#{tweet.url})    #{tweet.user.screen_name} #{tweet.text}";
  #sleep(3);
  #count=count+1;
  #before following user check if its alreay in list using bollean. 
  client.follow("#{tweet.user.screen_name}")
end
puts "Finished!\n\n"

require 'json'
require 'oauth'
require 'pp'

consumer_key        = 'xxxx'
consumer_secret     = 'xxxx'
access_token        = 'xxxx'
access_token_secret = 'xxxx'

consumer = OAuth::Consumer.new(
  consumer_key,
  consumer_secret,
  site:'https://api.twitter.com/'
)
endpoint = OAuth::AccessToken.new(consumer, access_token, access_token_secret)


puts "please enter phrase you want to search"
phrase_value=gets.chomp;


request_uri = "https://api.twitter.com/1.1/search/tweets.json?q=#{phrase_value}";

# GET
response = endpoint.get("#{request_uri}")
result = JSON.parse(response.body)

pp result

由于您已经在使用Twitter gem，为什么不使用它的搜索方法而不是自己编辑：

require 'twitter'

client = Twitter::REST::Client.new do |config|
  config.consumer_key = "3OpBStixWSMAzBttp6UWON7QA"
  config.consumer_secret = "MBmfQXoHLY61hYHzGYU8n69sQRQPheXJDejP1SKE2LBdgaqRg4"
  config.access_token = "322718806-qScub4diRzggWUO9DaLKMVKwXZcgrqHD2OFbwQTr"
  config.access_token_secret = "aWAIxQVnqF3nracQ0cC0HbRbSDxlCAaUIICorEAPlxIub"
end 

print "please enter phrase you want to search"
search_query = gets.chomp;

# @see https://github.com/sferik/twitter/blob/master/examples/Search.md
client.search(search_query, result_type: "recent").each do |tweet|
  puts "Count       Username                tweet"           
  puts "(#{tweet.url})    #{tweet.user.screen_name} #{tweet.text}";
end
