Ruby请求https – “在`read_nonblock’中：连接由对等体重置(Errno :: ECONNRESET)”

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？

解决方法

你的代码中有几个怪物.主要是：由于您使用SSL,您将通过以下方式知道HTTP.start：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

得到：
