Question

对于学校的项目我正在尝试使用Bandsintown api来显示用户在我的网站上关注的艺术家即将举行的音乐会。我能够以我想要的方式使用api开发，但是当涉及我的生产中的heroku网站时，没有显示任何错误，实际上我只收到一个空数组。也许你需要Bandsintown的许可才能在heroku上使用他们的api？我试过联系他们但还没有听到回复。

我的问题是，为什么我能够从Bandsintown获得开发但不是生产中的响应？一般来说是网络开发的新手，所以我以前没有碰到过这个......

这是我的代码：

calendar_controller.rb

class CalendarController < ApplicationController
  require 'uri'

  def index
    @user = current_user
    @hash_version_array = []

    @user.follows.each do |follow|
      response = HTTParty.get("http://api.bandsintown.com/artists/#{URI.escape(follow.artist_name)}/events/search.json?api_version=2.0&app_id=#{app_id}&location=use_geoip")
      @hash_version = JSON.parse(response.body)

      @hash_version_array << @hash_version if @hash_version != []
    end

    @hash_version_array
  end
end

日历/ index.html.erb

<h1><%= @user.name %>'s Calendar</h1>
<div>
  <h4 class="inline"><%= link_to "Calendar" %></h4>
  <h4 class="inline"><%= link_to "List" %></h4>
  <h4 class="inline"><%= link_to "Map" %></h4>
</div>
<br>

<% @hash_version_array.each do |date| %>
  <h3 class="artist_name"><%= date[0]["formatted_datetime"] %></h3>
  <% date[0]["artists"].each do |info| %>
    <h1 class="artist_name"><%= info["name"] %></h1>
    <br>
    <%= image_tag("#{info['thumb_url']}", class: 'artist_img') %>
  <% end %>

  <br>
  <br>

  <%= date[0]["venue"]["name"] %>
  <br>
  <%= date[0]["formatted_location"] %>, <%= date[0]["venue"]["country"] %>
  <br>
  Tickets <%= date[0]["ticket_status"].titleize %> <%= link_to("Buy", "#{date[0]['ticket_url']}") %>
  <br>
  <hr class="artists_hr">
<% end %>

Bandsintown在开发过程中的响应：

找出为什么我在Heroku上制作时没有得到任何东西，与location=use_geoip在这一行上有关：

response = HTTParty.get("http://api.bandsintown.com/artists/#{URI.escape(follow.artist_name)}/events/search.json?api_version=2.0&app_id=#{app_id}&location=use_geoip")

这适用于本地，因为它可以引用我的位置，然后搜索Bandsintown以获取正确的信息。但是，在Heroku上，它不知道如何正确引用位置。因此，我没有收到任何结果。

从rails应用程序在heroku上使用api时出现问题
