如何在Flask中分别上传多个文件？

from flask import Flask, request

app = Flask(__name__)

@app.route('/upload', methods=['POST'])
def upload():
    # 获取上传的文件
    files = request.files.getlist('file')
    
    # 遍历处理每个文件
    for file in files:
        filename = file.filename
        # 执行文件保存等操作
        file.save(filename)
    
    return '文件上传成功！'

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

from flask import Flask, request
from qcloud_cos import CosConfig
from qcloud_cos import CosS3Client

# 腾讯云COS的配置
secret_id = 'YOUR_SECRET_ID'
secret_key = 'YOUR_SECRET_KEY'
region = 'YOUR_REGION'
bucket = 'YOUR_BUCKET'

# 创建Flask应用程序
app = Flask(__name__)

# 配置腾讯云COS
config = CosConfig(Region=region, SecretId=secret_id, SecretKey=secret_key)
client = CosS3Client(config)

# 路由处理文件上传
@app.route('/upload', methods=['POST'])
def upload():
    # 获取上传的文件
    files = request.files.getlist('file')
    
    # 遍历处理每个文件
    for file in files:
        filename = file.filename
        # 上传文件到腾讯云COS
        response = client.put_object(
            Bucket=bucket,
            Body=file,
            Key=filename
        )
        # 打印上传结果
        print(response['ETag'])
    
    return '文件上传成功！'

# 运行Flask应用程序
if __name__ == '__main__':
    app.run()
