我正在尝试执行 oauth 所做的事情，试图了解如何使用授权标头。我也收到以下错误。我正在尝试连接到 linkedin API。
/usr/lib/ruby/1.8/net/http.rb:560:in 'initialize': getaddrinfo: 名称或服务未知 (SocketError)
如果有人可以推动我，我将非常感激正确的方向。

I am trying to do what oauth does in an attempt to understand how to use the Authorization headers. I am also getting the following error. I am trying to connect to the linkedin API.
/usr/lib/ruby/1.8/net/http.rb:560:in 'initialize': getaddrinfo: Name or service not known (SocketError)
I would really appreciate it if someone could nudge me in the right direction.

“名称或服务未知”是套接字级错误，通常指向无效的 IP 地址/DNS 主机名或未注册的端口名称（例如
telnet the.host.name 服务，其中service不是已注册的服务名称。）检查
CONNECT_URL是否包含有效的 URL。编辑：我不是 Ruby 程序员，但我不介意打赌
Net::HTTP.new需要一个主机名（例如 www.facebook.com）第一个参数，不是完整的 URL（例如 www.facebook.com/login.php?method=oauth）。"Name or service not known" is a socket-level error which usually points to either an invalid IP address/DNS hostname, or an unregistered port name (e.g.
telnet the.host.name servicewhereserviceis not a registered service name.)Check that
CONNECT_URLholds a valid URL.EDIT: I'm not a Ruby programmer, but I wouldn't mind betting that
Net::HTTP.newrequires a hostname (e.g. www.facebook.com) as the first argument, not a complete URL (e.g. www.facebook.com/login.php?method=oauth).当您没有 Internet 连接时，您也会收到此错误，因为 DNS 查找通常是使用主机名建立 TCP 连接时发生的第一件事。
拔下网络电缆并尝试：
You also get this error when you have no internet connection since a DNS lookup is often the first thing that happens when establishing a TCP connection using a hostname.
Unplug your network cable and try:
