ruby-on-rails - rails : How to send a http get request with UTF-8 encoding

Question

我正在尝试使用外部 API 来获取一些信息

  address=self.address
  response = HTTParty.get("http://api.map.baidu.com/geocoder/v2/?address=#{address}&output=json&ak=5dfe24c4762c0370324d273bc231f45a")
  decode_response =  ActiveSupport::JSON.decode(response)

但是地址是中文的，所以我需要转换成UTF-8编码， 如果不是，我会得到 URI::InvalidURIError (bad URI(is not URI?): How do it?

我尝试了address=self.address.force_encoding('utf-8')，但它不起作用，也许我应该使用其他方法？

更新:

  uri = "http://api.map.baidu.com/geocoder/v2/?address=#{address}&output=json&ak=5dfe24c4762c0370324d273bc231f45a"
  encoded_uri = URI::encode(uri)
  response = HTTParty.get(encoded_uri)
  decode_response =  ActiveSupport::JSON.decode(response)
  self.latitude = decode_response['result']['location']['lat']

我得到无法将 HTTParty::Response 转换为字符串。这是怎么回事？

I found something here ，我想我需要明确告诉 Httparty 用 JSON 解析它？

您可以将其保存到文件“geo.rb”并运行ruby geo.rb

require 'uri'
require 'httparty'

address = "中国上海"
uri = "http://api.map.baidu.com/geocoder/v2/?address=#{address}&output=json&ak=5dfe24c4762c0370324d273bc231f45a"
encoded_uri = URI::encode uri
puts HTTParty.get(encoded_uri)
