Python读取excel并形成api接口案例

from fastapi import FastAPI, HTTPException

app = FastAPI(title="Excel读取API", version="1.0")

# 读取配置文件
current_dir = os.path.dirname(os.path.abspath(__file__))
config_path = os.path.join(current_dir, "config.ini")
config = configparser.ConfigParser()
config.read(config_path, encoding="utf-8")
EXCEL_FILE_PATH = config["EXCEL"]["file_path"]

# API接口
@app.get("/read-excel")
