Question

我是Ruby新手。我已经开始阅读 Bastards Book Ruby 的第一章，即Tweet fetching，但本教程使用的是Twitter API v1。我得到的回应告诉我使用v1.1。所以，我按照教程编写了一个程序：

require 'oauth'

def prepare_access_token(oauth_token, oauth_token_secret)
    consumer = OAuth::Consumer.new("apiKey", "APISecret", { :site => "https://api.twitter.com", :scheme => :header })

    token_hash = { :oauth_token => oauth_token, :oauth_token_secret => oauth_token_secret }
    access_token = OAuth::AccessToken.from_hash(consumer, token_hash )

    return access_token
end

access_token = prepare_access_token("AccessToken", "AccessTokenSecret")

response = access_token.request(:get, "https://api.twitter.com/1.1/statuses/home_timeline.json")
puts response

输出：#<Net::HTTPOK:0x007fb7eb0885b8>

如果我在这里运行程序。它运行得很好。但是，如果我添加以下内容来获取推文并写入文件。我收到错误

twitter_user = "iAbhimanyuAryan"
remote_base_url = "https://api.twitter.com/1.1/statuses/user_timeline.json?count=100&screen_name="

remote_full_url = remote_base_url + twitter_user

tweets = open(remote_full_url).read

my_local_filename = twitter_user + "-tweets.json"

my_local_file = open(my_local_filename, "w")
      my_local_file.write(tweets)

my_local_file.close

错误：

查看man pages for the Twitter API，此请求需要身份验证。

您需要使用AccessToken对象发出请求。像这样：

# response is a [Net::HTTPResponse][3]
response = access_token.get(remote_full_url)

# Get the entire body of the response
tweets = response.body

注意，这是一种非常基本的方法。如果您将此类代码投入生产，则需要添加适当的检查和错误处理。

使用Ruby获取推文返回“open_http”：400错误请求（OpenURI :: HTTPError）
