Net::HTTP 无法访问 Google 文档列表数据 API

Question

我正在尝试使用 ruby​​ 中的 Net::HTTP 使用以下代码来使用 Google 文档列表数据 API 版本 3.0。

require 'net/http'

spreadsheets_uri = 'http://spreadsheets.google.com/feeds/spreadsheets/private/full'
docs_uri = "https://docs.google.com/feeds/default/private/full?v=3"

def get_feed(uri, headers=nil)
  uri = URI.parse(uri)
  Net::HTTP.start(uri.host, uri.port) do |http|
    return http.get(uri.path, headers)
  end 
end

def get_headers(service)
  http = Net::HTTP.new('www.google.com', 443)
  http.use_ssl = true
  path = '/accounts/ClientLogin'
  data = "accountType=HOSTED_OR_GOOGLE&Email=#{EM}&Passwd=#{PW}&service=#{service}"
  headers = { 'Content-Type' => 'application/x-www-form-urlencoded'}
  resp, data = http.post(path, data, headers)

  headers["Authorization"] = "GoogleLogin auth=#{data[/Auth=(.*)/, 1]}"
  headers["GData-Version"] = "3.0"
  headers
end

puts get_feed(spreadsheets_uri, get_headers("wise")) 
puts get_feed(docs_uri, get_headers("writely"))

这适用于

'http://spreadsheets.google.com/feeds/spreadsheets/private/full' 

但不适用于

 "https://docs.google.com/feeds/default/private/full?v=3"

引发以下错误的情况

/usr/local/lib/ruby/1.9.1/net/protocol.rb:135:in `read_nonblock': end of file reached (EOFError)

Answer 1

使用 ClientLogin 执行身份验证时，您必须为 DocsList API 指定正确的服务名称。您正在使用用于电子表格 API 的 service=wise ，尝试使用用于 DocsList API 的 service=writely 。

服务名称列表位于 http://code.google.com/apis /gdata/faq.html#clientlogin

Answer 2

您需要在请求中包含“verify_mode”选项。
我改变了你的“get_feed”方法，它对我有用。

def get_feed(uri, headers=nil)
  uri = URI.parse(uri)
  https = Net::HTTP.new(uri.host, uri.port)  
  https.use_ssl = true
  https.verify_mode = OpenSSL::SSL::VERIFY_NONE

  https.start do |http|
    return http.get(uri.request_uri, headers)
  end 
end
