Flask 中 formdata 上傳多個(gè)文件

在 Flask 中，我們可以使用 request.files 來(lái)獲取上傳的文件，當(dāng)用戶通過(guò)表單上傳多個(gè)文件時(shí)，這些文件會(huì)以列表的形式存儲(chǔ)在 request.files 中，下面是一個(gè)詳細(xì)的教程，包括小標(biāo)題和單元表格。

站在用戶的角度思考問(wèn)題，與客戶深入溝通，找到赤坎網(wǎng)站設(shè)計(jì)與赤坎網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗(yàn)，讓設(shè)計(jì)與互聯(lián)網(wǎng)技術(shù)結(jié)合，創(chuàng)造個(gè)性化、用戶體驗(yàn)好的作品，建站類型包括：網(wǎng)站制作、成都做網(wǎng)站、企業(yè)官網(wǎng)、英文網(wǎng)站、手機(jī)端網(wǎng)站、網(wǎng)站推廣、域名注冊(cè)、虛擬主機(jī)、企業(yè)郵箱。業(yè)務(wù)覆蓋赤坎地區(qū)。

準(zhǔn)備工作

1、安裝 Flask：確保已經(jīng)安裝了 Flask，如果沒(méi)有安裝，可以使用以下命令安裝：

pip install Flask

2、創(chuàng)建一個(gè)簡(jiǎn)單的 HTML 表單，用于上傳多個(gè)文件：

    
    
    


    

        
        
        上傳
    

Flask 后端處理文件上傳

1、創(chuàng)建一個(gè)簡(jiǎn)單的 Flask 應(yīng)用：

from flask import Flask, request, render_template_string
import os
app = Flask(__name__)

2、定義一個(gè)路由，用于處理文件上傳請(qǐng)求：

@app.route('/upload', methods=['POST'])
def upload_files():
    file1 = request.files['file1']  # 獲取第一個(gè)文件對(duì)象列表
    file2 = request.files['file2']  # 獲取第二個(gè)文件對(duì)象列表
    return 'Files uploaded successfully'

3、遍歷文件對(duì)象列表，將文件保存到指定目錄：

def save_files(file_list):
    for file in file_list:
        if file:  # 確保文件對(duì)象不為空
            filename = secure_filename(file.filename)  # 對(duì)文件名進(jìn)行安全處理，防止包含非法字符
            file.save(os.path.join('uploads', filename))  # 將文件保存到 uploads 目錄下

4、調(diào)用 save_files 函數(shù)，處理上傳的文件：

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