# MySQL 示例
db_host="localhost"
db_user="username"
db_pass="password"
db_name="database_name"
query="SELECT * FROM table_name;"
mysql -h $db_host -u $db_user -p$db_pass $db_name -e "$query"
# PostgreSQL 示例
db_host="localhost"
db_user="username"
db_pass="password"
db_name="database_name"
query="SELECT * FROM table_name;"
PGPASSWORD=$db_pass psql -h $db_host -U $db_user -d $db_name -c "$query"

import requests
api_url = "https://api.example.com/data"
