【问题描述】：

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，所以我选择了HTTP.new

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)

发出请求时 (response = http.request(request)) ruby 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 /usr/local/Cellar/ruby/2.2.2/lib/ruby/2.2.0/net/http.rb:879:in `block in connect'
    from /usr/local/Cellar/ruby/2.2.2/lib/ruby/2.2.0/timeout.rb:74:in `timeout'
    from /usr/local/Cellar/ruby/2.2.2/lib/ruby/2.2.0/net/http.rb:878:in `connect'
    from /usr/local/Cellar/ruby/2.2.2/lib/ruby/2.2.0/net/http.rb:863:in `do_start'
    from /usr/local/Cellar/ruby/2.2.2/lib/ruby/2.2.0/net/http.rb:852:in `start'
    from /usr/local/Cellar/ruby/2.2.2/lib/ruby/2.2.0/net/http.rb:1375:in `request'
    from (irb):14
    from /usr/local/bin/irb:11:in `<main>'

当我使用 http 时，同样的请求有效

【问题讨论】：

对我来说，问题实际上出在Net::HTTP.new(uri.host, uri.port, :use_ssl => uri.scheme == 'https')，因为这与不接受Hash 的Net::HTTP.new 的签名不匹配。方法签名是new(address, port = nil, p_addr = :ENV, p_port = nil, p_user = nil, p_pass = nil)。我觉得应该是http = Net::HTTP.new(uri.host, uri.port); http.use_ssl = uri.scheme == 'https';

【解决方案1】：

我不确定您没有使调用过于复杂。为什么不直接使用：

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

我假设您已经知道您的目标服务器是否需要 HTTPS。
