Heroku Python Web進程無法在60秒內綁定到$ PORT - 不是明顯的

Question

確實類似的問題以簡單的解決方案回答。不要以爲這是一樣的。首先是我的代碼，然後是日誌。我正在使用提供的PORT env變量，但仍然出現此錯誤。

if __name__ == "__main__": 
    import sys 
    print('HELLO %s' % str(sys.argv[1])) 
    #import os 
    import os 
    port = os.environ['PORT'] 
    print(port) 
    cherrypy.config.update({ 
         'server.socket_port': int(port), 
         }) 
    cherrypy.quickstart(House()) 

這裏談到的日誌

Answer 1

OK有在這一個陷阱夫婦的。到目前爲止，最常見的是不使用環境變量PORT中指定的端口。第二種是使用localhost或127.0.0.1（或者保留默認）指定的主機。指定主機爲0.0.0.0修復了我的問題。

if __name__ == "__main__": 
    import sys 
    print('HELLO %s' % str(sys.argv[1])) 
    import os 
    import os 
    port = os.environ['PORT'] 
    print(port) 
    cherrypy.config.update({ 
          'server.socket_host': '0.0.0.0', 
          'server.socket_port': int(port), 
          }) 
    cherrypy.quickstart(House())
