Question

我正在尝试将位于Web服务器上的数据库连接到机器人，但我不知道如何将数据库连接到机器人。我希望机器人能够从机器人运行SELECT和UPDATE查询。另一个问题是我不打算使用C语言或Java;我计划在主控制系统中使用python。

我知道： PHP VBScript中批量蟒

如果有人知道如何将数据库连接到机器人，那将是一个很大的帮助。

那么基本上如何在python中连接到SQL DB？我现在正在做一个虚拟机器人做同样的事情。查看模块，SQL-connector！

您将首先使用凭证

创建config.ini

[mysql]
host = localhost
database = python_mysql
user = root
password =

阅读Config.ini并返回字典

from configparser import ConfigParser 
def read_db_config(filename='config.ini', section='mysql'):
    """ Read database configuration file and return a dictionary object
    :param filename: name of the configuration file
    :param section: section of database configuration
    :return: a dictionary of database parameters
    """
    # create parser and read ini configuration file
    parser = ConfigParser()
    parser.read(filename)

    # get section, default to mysql
    db = {}
    if parser.has_section(section):
        items = parser.items(section)
        for item in items:
            db[item[0]] = item[1]
    else:
        raise Exception('{0} not found in the {1} file'.format(section, filename))

    return db

并连接到MYSQL数据库

from mysql.connector import MySQLConnection, Error
from python_mysql_dbconfig import read_db_config


def connect():
    """ Connect to MySQL database """

    db_config = read_db_config()

    try:
        print('Connecting to MySQL database...')
        conn = MySQLConnection(**db_config)

        if conn.is_connected():
            print('connection established.')
        else:
            print('connection failed.')

    except Error as error:
        print(error)

    finally:
        conn.close()
        print('Connection closed.')


if __name__ == '__main__':
    connect()

和更新语句如下所示

def update_book(book_id, title):
    # read database configuration
    db_config = read_db_config()

    # prepare query and data
    query = """ UPDATE books
                SET title = %s
                WHERE id = %s """

    data = (title, book_id)

    try:
        conn = MySQLConnection(**db_config)

        # update book title
        cursor = conn.cursor()
        cursor.execute(query, data)

        # accept the changes
        conn.commit()

    except Error as error:
        print(error)

    finally:
        cursor.close()
        conn.close()


if __name__ == '__main__':
    update_book(37, 'The Giant on the Hill *** TEST ***')
