Ruby faraday openweathermap api 配置块然后 conn.get 块

Question

require 'faraday'
require 'pry'

ENV['API'] = "XXXXXXXXXXXX"



conn = Faraday.new(:url => 'http://api.openweathermap.org/data/2.5') do|faraday|
  faraday.request  :url_encoded             # form-encode POST params
  faraday.response :logger                  # log requests to STDOUT
  faraday.adapter  Faraday.default_adapter  # make requests with 
  Net::HTTP
end

response = conn.get do |req|
            req.url '/weather'
            req.params['q'] = 'oskaloosa'
            req.params['APPID'] = ENV['API']
            req.params['units'] = 'metric'
           end

以上是我目前使用的配置块和请求块，不幸的是它没有产生我想要的结果。

我收到：

#<Faraday::Response:0x00007f7f4aa331f0
 @env=
  #<struct Faraday::Env
   method=:get,
   body=

   url=

     oauth=nil,
     context=nil>,
   request_headers={"User-Agent"=>"Faraday v0.13.1"},
   ssl=

     client_cert=nil,
     client_key=nil,
     certificate=nil,
     private_key=nil,
     verify_depth=nil,
     version=nil>,
   parallel_manager=nil,
   params=nil,
   response=#<Faraday::Response:0x00007f7f4aa331f0 ...>,
   response_headers=
    {"server"=>"openresty",
     "date"=>"Sun, 12 Nov 2017 22:55:30 GMT",
     "content-type"=>"text/html",
     "content-length"=>"162",
     "connection"=>"close"},
    status=404,
   reason_phrase="Not Found">,
 @on_complete_callbacks=[]>

我第一次看到 404 响应，很明显 get 请求没有正常工作。经过检查，我发现最后的 url 没有正确编码参数。 url 目前是： #<URI::HTTP http://api.openweathermap.org/weather?APPID=95cade087f6f767d179feaa301816de4&q=oskaloosa&units=metric>

而实际上我试图构建的正确 url 是： #<URI::HTTP http://api.openweathermap.org/weather?q=oskaloosa&APPID=95cade087f6f767d179feaa301816de4&units=metric> .

现在我知道我可以用 #{param['key']) 或 #{@key}` 进行字符串插值，但我正尝试只为这个 conn 和 request/response 循环使用块构造。

任何人都可以给我一些建议或阐明这个话题吗？

require 'faraday'
require 'pry'

ENV['API'] = "95cade087f6f767d179feaa301816de4"



conn = Faraday.new(:url => 'http://api.openweathermap.org') do |faraday|
  faraday.request  :url_encoded             # form-encode POST params
  faraday.response :logger                  # log requests to STDOUT
  faraday.adapter  Faraday.default_adapter  # make requests with Net::HTTP
end

response = conn.get do |req|
            req.url '/data/2.5/weather'
            req.params['q'] = 'oskaloosa'
            req.params['APPID'] = ENV['API']
            req.params['units'] = 'metric'
           end
