如何将爬取的数据存储到数据库中?

要将爬取的数据存储到MySQL数据库中,可以使用Python编程语言结合MySQL数据库的连接库来实现。以下是一个基本的步骤指南:

  1. 安装必要的库

    • 确保安装了mysql-connector-python库,可以通过以下命令安装:
      pip install mysql-connector-python
  2. 连接到MySQL数据库

    • 使用mysql.connector模块连接到MySQL数据库。以下是一个示例代码:

      import mysql.connector
      
      # 创建数据库连接
      connection = mysql.connector.connect(
          host='localhost',  # 数据库主机地址
          user='yourusername',  # 数据库用户名
          password='yourpassword',  # 数据库密码
          database='yourdatabase'  # 数据库名称
      )
      
      cursor = connection.cursor()
  3. 创建表格(如果尚未创建)

    • 使用SQL命令创建存储数据的表格。例如,创建一个存储书籍信息的表:
      create_table_query = '''
      CREATE TABLE IF NOT EXISTS books (
          id INT AUTO_INCREMENT PRIMARY KEY,
          category VARCHAR(255),
          author VARCHAR(255),
          title VARCHAR(255),
          price DECIMAL(10, 2)
      )
      '''
      cursor.execute(create_table_query)
  4. 插入数据

    • 将爬取的数据插入到数据库中。假设你有一个包含书籍信息的字典列表:

      books = [
          {'category': 'reference', 'author': 'Nigel Rees', 'title': 'Sayings of the Century', 'price': 8.95},
          {'category': 'fiction', 'author': 'Evelyn Waugh', 'title': 'Sword of Honour', 'price': 12.99},
          # 更多书籍数据...
      ]
      
      insert_query = '''
      INSERT INTO books (category, author, title, price)
      VALUES (%s, %s, %s, %s)
      '''
      
      for book in books:
          cursor.execute(insert_query, (book['category'], book['author'], book['title'], book['price']))
      
      connection.commit()  # 提交事务
  5. 关闭连接

    • 完成操作后,关闭数据库连接:
      cursor.close()
      connection.close()

通过以上步骤,你可以将爬取的数据存储到MySQL数据库中。请根据实际情况调整数据库连接参数和数据结构。
