scrapy中yield抛出了，但不执行

Question

问题描述

scrapy对于同一个url用不同的方法给parse，有的能执行，有的就不能

问题出现的环境背景及自己尝试过哪些方法

相关代码

urls=['http://maoyan.com/xseats/201809300156836?movieId=342166&cinemaId=16887','http://maoyan.com/xseats/201809300237849?movieId=1210830&cinemaId=2285','http://maoyan.com/xseats/201809300013842?movieId=1217402&cinemaId=13199']
    for url in urls:
        yield Request(url=url,callback=self.parse)
        

这个parse就能执行

    # # 从数据库中获得城市的id
    myclient = pymongo.MongoClient("mongodb://localhost:27017/")
    mydb = myclient["scrapy"]
    mycol_movie = mydb["movieTime"]

    movies=list(mycol_movie.find().sort([("movieTime",1)]))
    for movie in movies:
        now = float(datetime.datetime.now().strftime('%H.%M'))
        if (now > movie['movieTime']):
            print(str(movie['movieTime']) + "  过时了")
        else:
            while True:
                if (movie['movieTime'] < now + 0.07):
                    now = float(datetime.datetime.now().strftime('%H.%M'))
                    print(str(now)+"     "+str(movie['movieTime']))
                    url="http://maoyan.com" + str(movie['movieUrl'])
                    print(url)
                    try:
                        yield Request(url=url, callback=self.parse)
                    except:
                        print("抛出失败！！！")
                    finally:
                        print('抛出了反正')
                        print("  ")
                    break
                else:
                    print("暂停45秒，，")
                    time.sleep(60)
                    now = float(datetime.datetime.now().strftime('%H.%M'))

这个就不能执行，

你期待的结果是什么？实际看到的错误信息又是什么？

让复杂的能够执行。
