通过使用Flask框架实现一个简单的图片上传工具，当用户提交图片后会自动将图片保存到upload目录下，代码如下
import os
from flask import Flask, request
import random
import string
import datetime
ALLOWED_EXTENSIONS = set(['rar', 'zip' ,'xls','xlsx','docx','doc','html','png', 'jpg', 'jpeg', 'gif'])
app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = "./upload_file" # 将文件上传到当前目录
app.config['MAX_CONTENT_LENGTH'] = 32 * 1024 * 1024 # 限制只能上传16M的文件
html = '''
<!DOCTYPE html>
<form action="" method="post" enctype="multipart/form-data">
请求序号: {} <br><br>
下单日期: {} <br><br>
接收邮箱: <input type="text" id="email" name="email"><br><br>
需求描述: <textarea rows="5" cols="37" id="my_text" name="my_text" value=""></textarea><br><br>
上传文件: <input type="file" name="file"><br><br>
<b>----------------------------------------</b>
<br> 注: 多个文件请压缩为 .rar .zip 压缩包后上传<br>
<b>----------------------------------------</b><br><br>
<input type="submit" value="提交订单请求">
</form>
'''
ref_html = '''
<b>------------------------------------------------------</b>

付款订单号: {} <br><br>
接收邮件地址: {} <br><br>
