如何获取多个JSON URL并解析动态内容

我正在尝试创建第一个从TMDB的API解析数据的应用程序

当我尝试加载和解析一个URL时，一切正常：

uri = URI.parse("http://api.themoviedb.org/3/tv/#URI.escape(@id)}?api_key=#{@api_key}")
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)
@results = JSON.load(response.body)

但现在我想解析JSON，可从以下网址获得：

/tv/{tv_id}/season/{season_number}/episode/{episode_number}

其中：

{tv_id}

是

@id=params[：id]

{season\u number}

和

{season\u number}

是由第一个URL生成的季节和集。 我尝试了多种方法，但每次都会出现随机错误

完整代码已打开。 正在运行的应用程序是

我试图在同一个页面上显示赛季标题和剧集。 例如，当我解析时：

https://api.themoviedb.org/3/tv/2432?api_key=**********

我得到：

{
"backdrop_path":"/hl9mC6fc2adfeGpI1ijKCfQ0KzI.jpg",
"name":"Taken",
"number_of_episodes":10,
"number_of_seasons":1
}

所以我一季有10集。对于每一集，我都有一个URL，将集号

{1..5..10}

替换为：

https://api.themoviedb.org/3/tv/8681/season/1/episode/*1*?api_key=********

我想显示每一集的集名，因此一集的JSON结果如下：

{
"name":"Beyond the Sky","overview":"......",
"id":183273,
"vote_average":0.0,
"vote_count":0
}

对于该请求，您需要使用https，请参阅我用#**标记的需要更改的部分。请注意使用Net:：HTTP.start而不是Net:：HTTP.new。 顺便说一下，这是一款不错的应用程序

require 'net/http'
require 'net/https' #*add*
require 'json'
require 'open-uri'

url = 'https://api.themoviedb.org/3/tv/1418/season/1/episode/1?api_key=**************************&language=en-US'
uri = URI.parse(url)
# *adapt following line*
http = Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https', :verify_mode => OpenSSL::SSL::VERIFY_NONE)
request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)
json = JSON.load(response.body)

编辑：要获得一季的所有剧集，你只需从1到剧集数进行计数，然后组合并请求新的url。 你将不得不做同样的事情来列举一个系列的所有季节，但我留给你一些工作超过8:）成功

require 'net/http'
require 'net/https'
require 'json'
require 'open-uri'
require 'pp'

# we have to do this more than once, so let's make it DRY
def get_json url
  uri = URI.parse(url)
  http = Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https', :verify_mode => OpenSSL::SSL::VERIFY_NONE) #**
  request = Net::HTTP::Get.new(uri.request_uri)
  response = http.request(request)
  JSON.load(response.body)
end

API_KEY  = '****************************'
url = "https://api.themoviedb.org/3/tv/2432?api_key=#{API_KEY}"
season = get_json url

season['number_of_episodes'].to_i.times do |episode|
  episode += 1 # times starts from 0 , so we add 1
  url = "https://api.themoviedb.org/3/tv/8681/season/1/episode/#{episode}?api_key=#{API_KEY}"
  episode = get_json url
  # pp episode
  puts episode['name']
end

gives

# Great White Shark: The True Story of Jaws
# Polar Bear: The Arctic Warrior
# Crocodile: The Smiling Predator
# Leopard: The Agent of Darkness
# Eagle: The Master of the Skies
# Humpback Whale: The Giant of the Oceans
# Wolf: The Legendary Outlaw
# Tiger: The Elusive Princess
# Lions: Spy in the Den
# Grizzly: Face to Face

您可以手动点击JSON端点（使用curl或Postman等）并获得您期望的结果吗？您会得到什么“随机错误”？对你来说，这可能是随机的，但错误是显著的，很少是随机的。请阅读“.Jhon Feltz，是的，我可以一个一个地获取所有url。Tin Man我的意思是，对于每次搜索，我都会得到一个错误，但通常使用未初始化的常量，因为我试图在值为零时获取多个json url。请让我知道它是否有效，然后接受答案，我还想看看最后的版本对不起，彼得先生，你的评论很好！！并更正了我的代码，但问题不是访问安全url，而是在子url依赖于第一个oneNo问题时访问多个url，并将其添加到我的答案中
