Ruby Net::HTTP 使用 https 时获取请求错误

Question

我有一个网络服务器，我需要从中获取一些数据。我想重用连接，这就是我选择 HTTP.new

的原因

require "net/http"
require "openssl"
uri = URI.parse("https://example.com")
path = "/index.html"
http = Net::HTTP.new(uri.host, uri.port,
    :use_ssl => uri.scheme == 'https')
request = Net::HTTP::Get.new "/index.html"
response = http.request(request)

当发出请求 (response = http.request(request)) 时，ruby 会抛出一个 TypeError:

TypeError: no implicit conversion of Hash into String
    from /usr/local/Cellar/ruby/2.2.2/lib/ruby/2.2.0/net/http.rb:879:in `initialize'
    from /usr/local/Cellar/ruby/2.2.2/lib/ruby/2.2.0/net/http.rb:879:in `open'

    from (irb):14

当我使用 http 时同样的请求有效

我不确定您是否使调用过于复杂。为什么不直接使用:

http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true

我的假设是您已经知道您的目标服务器是否需要 HTTPS。
