对 https 的 Ruby 请求 - "in ` read_nonblock':连接由对等方重置(Errno::ECONNRESET)”

Question

这是我的代码

domain = 'http://www.google.com'
url = URI.parse "https://graph.facebook.com/fql?q=SELECT%20url,normalized_url%20FROM%20link_stat%20WHERE%20url='#{domain}'"
req = Net::HTTP::Get.new url.path
res = Net::HTTP.start(url.host, url.port) {|http| http.request req}
puts res.body

它给了我

我做错了什么？

您的代码中有几个奇怪的地方。主要是:因为你使用 SSL 你要知道 HTTP.start 关于 :use_ssl => url.scheme == 'https' . HTTP.Get 构造函数等待 URI，而不是路径。总结:

domain = 'http://www.google.com'
url = URI.parse("https://graph.facebook.com/fql?q=SELECT%20url,normalized_url%20FROM%20link_stat%20WHERE%20url='#{domain}'")
req = Net::HTTP::Get.new url 
res = Net::HTTP.start(url.host, url.port, 
        :use_ssl => url.scheme == 'https') {|http| http.request req}
puts res 

给予:
