見《宋書·范曄傳》：“言之皆有實證，非為空談。”子平有較高的或然率，但如果沒有人物經(jīng)歷來佐證，就變成三教九流，成為“玄學”實在可惜。老外搞個mbti性格測試就巴巴說是科學，有智慧的老前輩總結的經(jīng)驗，因為不懂而無法傳承，散落在明間成為偷偷么么被人看不起，實在是看不過去。
有時候感覺西方人很笨，調研70多個家庭跟蹤他們的一生，然后給出結論發(fā)表論文。然后中國的學生就認為人家嚴謹有科學研究精神，何曾想過這70個樣本想對人類這么大基數(shù)根本不值得一提。另外一個視角，研究問題真的需要采用這么笨的方法嗎？梁湘潤大師等都說看一個人生的70%就不錯了，是的人的極限估計也差不多是這些，另外20~30%還需要靠國運、環(huán)境和個人修養(yǎng)，人之一生豈是幾百頁的子平能講完的呢，那豈不是白活。
我是會一些計算機，另外對梁老的一些觀點特別認同，大部分人都是普通人，每天為了家計小常奔波，為了妻財子祿壽而焦慮，要想做人上人，你真的能承受他們所經(jīng)歷的嗎？
這篇博客主要是從百度百科上采集人物經(jīng)歷，后面再結合子平理論進行實證。

3 數(shù)據(jù)管道

from sqlalchemy.engine import create_engine from personspider.items.baidu_person import BaiduPersonItem,BaiduPersonExperienceItem\,BaiduUrlItem,BaiduPersonRelationItem from personspider.service.baidu_service import BaiduPersonService,BaiduPersonExperienceService\,BaiduPerson,BaiduPersonExperience,BaiduPersonRelation,BaiduUrl\,BaiduPersonRelationService,BaiduUrlServiceclass MysqlPipeline(object):def __init__(self, engine):self.baiduPersonService = BaiduPersonService(engine)self.baiduPersonExperienceService = BaiduPersonExperienceService(engine)self.baiduUrlService = BaiduUrlService(engine)self.baiduPersonRelationService = BaiduPersonRelationService(engine)def process_item(self, item, spider):if type(item) == BaiduPersonItem:record = BaiduPerson(**item)self.baiduPersonService.insert(record)elif type(item) == BaiduPersonExperienceItem:record = BaiduPersonExperience(**item)self.baiduPersonExperienceService.insert(record)elif type(item) == BaiduUrlItem:record = BaiduUrl(**item)self.baiduUrlService.insert(record)elif type(item) == BaiduPersonRelationItem:record = BaiduPersonRelation(**item)self.baiduPersonRelationService.insert(record)@classmethoddef from_settings(cls,settings):mysql_config = settings.get('MYSQL_CONFIG')engine = create_engine('mysql+pymysql://{}:{}@{}:3306/{}'.format(mysql_config['user'], mysql_config['password'],mysql_config['host'], mysql_config['db']),connect_args={'charset': 'utf8'}, pool_size=mysql_config['pool_size'])return cls(engine)

4 寫數(shù)據(jù)庫

class BaiduPersonService(object):def __init__(self, engine):self.engine = engineSession = sessionmaker(engine)self.session = Session()self.emailService = EmailService()def exist(self, id):query = self.session.query(BaiduPerson).filter(BaiduPerson.id==id)return query.count()>0def insert(self, record):if not self.exist(record.id):try:record.create_time = datetime.datetime.now()self.session.add(record)self.session.commit()except Exception as e:title = r'{}寫入數(shù)據(jù)庫失敗'.format(record.cn_name)content = r'ERROR {}'.format(str(e))self.emailService.sendEmail(title,content)

5 異常郵件發(fā)送
如果在解析過程中出現(xiàn)異常，總不需要時刻盯著吧，寫個發(fā)郵件告知我，豈不是很安逸
