【爬虫实战】——利用bs4和sqlalchemy操作mysql数据库，实现网站多行数据表格爬取数据

标签：10 sqlalchemy name bs4 板卷爬取 Q235B 1500 热轧板

前言

此篇接上一篇的内容，在其基础上爬取网站的多行表格数据，以及把数据写入到mysql数据库中

一、定位表格查找元素

首先打开网站，如图需要爬取多行数据的表格，利用查找元素定位，看图中分析得知我要爬取的是tr下的td数据，所以先查找到tr行

    def script(self):
        # 先定位查找到tr行元素
        trs = self.soup().select('.content>table>tbody>tr')
        print(trs)

二、提取数据

我们可以看到爬取出每行的tr和tr下面的td数据，接下来利用for循环把tr每行的文字提取出来，但是前两行是我不需要的，我只要第三行之后的数据

代码如下：

    def __init__(self):


        # self.url = "https://www.cnblogs.com/Owen-ET/p/14523426.html"
        self.url = "http://www.gtgqw.com/j/showhz2136672.html"
        # url = "http://www.example.com"
        self.dic = {
            "报价": []
        }


    def script(self):

        trs = self.soup().select('.content>table>tbody>tr')
        print(trs)
        print("=========================此处代码↓========================================")
        for tr in trs:
            if (tr != trs[0])&(tr != trs[1]):
                movie = {}
                infos = list(tr.stripped_strings)
                print(infos)    # 输出结果①：把td里面的值遍历出来组成数组
                movie['pin_name'] = infos[0]
                movie['guige'] = infos[1]
                movie['caizhi'] = infos[2]
                movie['chandi'] = infos[3]
                movie['jiage'] = infos[4]
                movie['zhangdie'] = infos[5]
                # 
                self.dic["报价"].append(movie)
        print("========================此处代码↑=========================================")
        return self.dic    # 输出结果②：把每行td数组里的元素赋上键名，组成键值对

三、写入mysql数据库

把上一步提取到的数据，利用sqlalchemy操作写入mysql数据库中，首先前提

    def mysql(self):

        # 替换为你的数据库连接信息
        DATABASE_URI = 'mysql+pymysql://root:1234567@localhost:3306/baojia'

        # 创建数据库引擎
        engine = create_engine(DATABASE_URI)
        Session = sessionmaker(bind=engine)
        session = Session()

        # 定义JSON数据和表结构
        json_data = self.script()['报价']

        # 假设你有一个名为users的表
        metadata = MetaData(bind=engine)
        users_table = Table('banjuan', metadata, autoload_with=engine)

        # 解析JSON数据并插入到数据库
        for entry in json_data:
            ins = users_table.insert().values(pin_name=entry['pin_name'],
                                              guige=entry['guige'],
                                              caizhi=entry['caizhi'],
                                              chandi=entry['chandi'],
                                              jiage=entry['jiage'],
                                              zhangdie=entry['zhangdie'])
            session.execute(ins)

        # 提交更改
        session.commit()

配置数据库解析：'mysql+pymysql://root:1234567@localhost:3306/baojia'
可以参考我的相关文章也有说明：Owen_ET-《【测试平台开发】——05Flask后端api开发实战(二)—— SqlAlchemy 》 *****

【mysql】：使用的mysql数据库

【pymysql】：使用pymysql的引擎

【://scott】：数据库用户名

【:tiger】：数据库密码

【@localhost】：数据库地址

【/foo】：数据库的库名称

手动创建表结构：数据库名为【baojia】、表名为【banjuan】，以及各个字段值的类型、长度等

其中id设置为自动增加并且设置为键

【运行结果：查看数据库】

运行之后，mysql数据库的数据就插进来了
