Python：Json數據到類實例變量中

-1

我正在嘗試創建一個名爲Movie的類。我已經聲明瞭實例變量。我打電話給OMDB API，我想存儲分配變量。但這似乎並沒有奏效。即使當我打印json_Data時，它也不會打印任何東西。任何人都可以指向正確的方向。我知道我可以將數據存儲到字典中。但是它將如何存儲在一個類中。我是一個仍在學習python的newbiew。Python：Json數據到類實例變量中

class Movie(object): 
    """ Class provides a structure to store Movie information """ 



    def __init__(self, imdb_id, title = None, release_year = None, rating = None, run_time = None, genre = None, director = None, actors = None, plot = None, awards = None, poster_image = None, imdb_votes = None, youtube_trailer = None): 
     self.imdb_id = imdb_id 
     self.title = title 
     self.release_year = release_year 
     self.rating = rating 
     self.run_time = run_time 
     self.genre = genre 
     self.director = director 
     self.actors = actors 
     self.plot = plot 
     self.awards = awards 
     self.poster_image = poster_image 
     self.imdb_votes = imdb_votes 
     self.youtube_trailer = youtube_trailer 


    def get_api_data(self): 
     """ 
      Method retreves and parses information for each movie based on imdb_id 
     """ 
      #URL for OMDBI 
     url = "http://www.omdbapi.com/?i="+self.imdb_id+"&plot=full&r=json&v=1" 
     try: 
      response = urllib.urlopen(url) 

     except URLERROR as e: 
      if hasattr(e, 'reason'): 
       print ("Unable to reach a server.") 
       print 'Reason: ', e.reason 
      elif hasattr(e, 'code'): 
       print "Server is unable to fulfill the request." 
       print 'Error Code: ', e.code 
      else: 
       json_data = json.loads(response.read()) 
       self.imdb_id = json_data["imdbID"].encode("utf8","ignore") 
       self.title = json_data["Title"].encode("utf8","ignore") 
       self.release_year = int(json_data["Released"].split("")[-1]) 
       self.rating = json_data["imdbRating"].encode("utf8", "ignore") 
       self.run_time = json_data["Runtime"].encode("utf8", "ignore") 
       self.genre = json_data["Rated"].encode("utf8", "ignore") 
       self.director = json_data["Director"].encode("utf8", "ignore") 
       self.actors = json_data["Actors"].encode("utf8", "ignore") 
       self.plot = json_data["Plot"].encode("utf8", "ignore") 
       self.awards = json_data["Awards"].encode("utf8", "ignore") 
       self.poster_image = json_data["Poster"].encode("utf8", "ignore") 
       self.imdb_votes = json_data["imdbVotes"].encode("utf8", "ignore")

是否建議將返回的數據存儲爲字典，而不是爲每種電影類型創建類？

最後的else：仍然在except子句中，所以如果try：成功，你的代碼永遠不會到達那個塊。 –
