我使用的是 ruby-1.8.7-p302/Rails 2.3.11。我正在尝试使用 FQL (Facebook API)来获得一个链接的统计数据。这是我的密码:
def stats(fb_post_url)
url = BASE_URI + "?query=#{URI.encode("select like_count from link_stat where url=\"#{fb_post_url}\"")}"
parsed_url = URI.parse(url)
http = Net::HTTP.new(parsed_url.host, parsed_url.port)
request = Net::HTTP::Get.new(parsed_url.request_uri)
response = http.request(request)
response.inspect
end
这里有一个错误:
EOFError: end of file reached

这似乎只发生在 Facebook API 的情况下。另外,我在一些文章中看到这可能是 Net: : HTTP 中的一个 bug。
