我想获取json表单url：
uri = URI.parse("http://84.38.185.251:9262/send")
http = Net::HTTP.new(uri.host,uri.port)
request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)
response.code # => 301
response.body # => The body (HTML,XML,blob,whatever)
response["cache-control"] # => public,max-age=2592000
puts response.body
但我收到一个错误：`EOFError(文件结束)：
app / controllers / sensors_controller.rb：35：在sensinfo’
sensors_controller.rb：35：
response = http.request(request)
我做错了什么？
