URI 提取在冒号处转义，有什么方法可以避免这种情况吗？

我有下面的函数，通常会输出一个 URL，例如 path.com/p/12345。

有时，当推文之前包含冒号时，例如

RT：一些path.com/p/123

函数将返回的内容：

personName:
path.com/p/12345

我的功能：

$a = 10

def grabTweets()
  tweet = Twitter.search("[pic] "+" path.com/p/", :rpp => $a, :result_type => "recent").map do |status|
    tweet = "#{status.text}" #class = string
    urls = URI::extract(tweet) #returns an array of strings
  end
end

我的目标是找到 URL 之前带有冒号的任何推文，并将该结果从循环中删除，以便它不会返回到创建的数组。

I have the following function below that will normally spit out a URL such as path.com/p/12345.

Sometimes, when a tweet contains a colon before the tweet such as

RT: Something path.com/p/123

the function will return:

personName:
path.com/p/12345

My function:

$a = 10

def grabTweets()
  tweet = Twitter.search("[pic] "+" path.com/p/", :rpp => $a, :result_type => "recent").map do |status|
    tweet = "#{status.text}" #class = string
    urls = URI::extract(tweet) #returns an array of strings
  end
end

My goal is to find any tweet with a colon before the URL and remove that result from the loop so that it is not returned to the array that is created.

你只能选择HTTP URL：

URI.extract("RT: Something http://path.com/p/123")
  # => ["RT:", "http://path.com/p/123"]

URI.extract("RT: Something http://path.com/p/123", "http")
  # => ["http://path.com/p/123"]

你的方法也可以清理很多，你有很多多余的局部变量：

def grabTweets
  Twitter.search("[pic] "+" path.com/p/", :rpp => $a, :result_type => "recent").map do |status|
    URI.extract(status.text, "http")
  end
end

我也想强烈反对你使用全局变量（$a）。

You can only select HTTP URLs:

URI.extract("RT: Something http://path.com/p/123")
  # => ["RT:", "http://path.com/p/123"]

URI.extract("RT: Something http://path.com/p/123", "http")
  # => ["http://path.com/p/123"]

Your method can also be cleaned up quite a bit, you have a lot of superfluous local variables:

def grabTweets
  Twitter.search("[pic] "+" path.com/p/", :rpp => $a, :result_type => "recent").map do |status|
    URI.extract(status.text, "http")
  end
end

I also want to strongly discourage your use of a global variable ($a).
