使用HTTP源读取CSV导出时出现云数据融合问题

import csv

# 示例代码：读取CSV文件
with open('data.csv', 'r', encoding='utf-8') as file:
    reader = csv.reader(file)
    for row in reader:
        print(row)

# 示例代码：指定编码格式读取CSV文件
with open('data.csv', 'r', encoding='utf-8') as file:
    reader = csv.reader(file)
    for row in reader:
        print(row)

import requests

# 示例代码：重试机制
for i in range(3):
    try:
        response = requests.get('http://example.com/data.csv')
        response.raise_for_status()
        break
    except requests.exceptions.RequestException as e:
        print(f"Request failed: {e}")

# 示例代码：服务器端处理CSV文件
from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/upload', methods=['POST'])
def upload_file():
    file = request.files['file']
    if file and file.filename.endswith('.csv'):
        try:
            # 处理CSV文件
            return jsonify({"status": "success"})
        except Exception as e:
            return jsonify({"status": "error", "message": str(e)})
    return jsonify({"status": "error", "message": "Invalid file format"})

if __name__ == '__main__':
    app.run(debug=True)
