使用Flask开发微信小程序后端的步骤如下:
1.安装Flask框架和微信开发工具包
```shell
pip install Flask
pip install Flask-Wx
```
2.创建Flask应用程序
```python
from flask import Flask, request
from flask_wx import WxApp
app = Flask(__name__)
wxapp = WxApp(app)
@app.route('/wechat', methods=['GET', 'POST'])
def wechat():
if request.method == 'GET':
return request.args.get('echostr', '')
else:
msg = wxapp.parse_message(request.data)
return wxapp.response_text(msg, content='Hello, World!')
```

在微信公众平台上配置服务器地址为`http://yourdomain.com/wechat`,并将Token设置为Flask应用程序中的Token。
4.运行Flask应用程序
```shell
export FLASK_APP=app.py
