EOFError:文件结尾与Net :: HTTP达成问题

Question

我使用的是ruby-1.8.7-p302/Rails 2.3.11.我正在尝试使用FQL(Facebook API)获取链接的统计信息.这是我的代码:

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

这是错误:

EOFError: end of file reached

这似乎只在Facebook API的情况下发生.另外,我在一些帖子中看到它可能是Net :: HTTP中的一个错误.

Answer 1

如果URL使用https而不是http,则需要添加以下行:

parsed_url = URI.parse(url)
http = Net::HTTP.new(parsed_url.host, parsed_url.port)
http.use_ssl = true

请注意附加http.use_ssl = true.

而处理http和https的更合适的代码将类似于以下代码.

url = URI.parse(domain)
req = Net::HTTP::Post.new(url.request_uri)
req.set_form_data({'name'=>'Sur Max', 'email'=>'some@email.com'})
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = (url.scheme == "https")
response = http.request(req)

Answer 2

我对非SSL服务的请求有类似的问题.

这篇博客模糊地建议尝试URI编码传递给'get'的URL:http://www.loudthinking.org/2010/02/ruby-eoferror-end-of-file-reached.html

基于绝望,我对它进行了拍摄,在我的限制测试中,这似乎已经为我修复了它.我的新代码是:

@http = Net::HTTP.new('domain.com')  
@http = @http.start    
url = 'http://domain.com/requested_url?blah=blah&etc=1'
req = Net::HTTP::Get.new(URI.encode(url))
req.basic_auth USERNAME, API_KEY
res = @http.request(req) 

请注意,我使用@ http.start,因为我想在多个请求上维护HTTP会话.除此之外,您可能想尝试最相关的部分,即:get调用中的URI.encode(url)
