Ruby on Rails 中带有 http.request 的 EOFError（到达文件末尾）

Question

我正在尝试获取 json 表单网址：

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

但我得到一个错误：`EOFError（到达文件末尾）： app/controllers/sensors_controller.rb:35:in sensinfo'

sensors_controller.rb:35：

response = http.request(request)

我做错了什么？

Answer 1

这个错误主要是因为使用 https

如果是https那么

请试试这个

uri = URI.parse("https://84.38.185.251:9262/send")
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Get.new(uri.request_uri)
http.use_ssl = true  
response = http.request(request)

注意补充

http.use_ssl = true

如果不是https

http.use_ssl = false

或者你可以添加条件

http.use_ssl = true if domain =~ /^https/

Answer 2

我认为这是某种错误； typhoeus 似乎有效：

require 'typhoeus'

response = Typhoeus.get("http://84.38.185.251:9262/send")
p response.body
#=> {"ids":"-1","data":{"temp":"nan","h":"-1"},"status":"255","voltage":"-1"}
