Tôi đang sử dụng ruby-1.8.7-p302 / Rails 2.3.11. Tôi đang cố gắng sử dụng FQL (API Facebook) để lấy số liệu thống kê cho một liên kết. Đây là mã của tôi:
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
Và đây là lỗi:
EOFError: end of file reached

Điều này dường như chỉ xảy ra trong trường hợp API Facebook. Ngoài ra, tôi thấy nó được đề xuất trong một số bài đăng này có thể là một lỗi trong Net :: HTTP.
