先上效果图:
文件名称为register.html
前端代码只做为参考,像flex布局,rem适配,js部分等,就自行学习吧 ^ ^
jquery用的是百度的地址(访问速度快):

python代码,命名为register.py
:
from flask import Flask, render_template, request, jsonify
import json
app = Flask(__name__)
@app.route('/',methods=["GET", "POST"])
def hello():
if request.method == 'GET':
print(request.method)
return render_template('register.html')
else:
print(request.method)
data = json.loads(request.get_data(as_text=True))
print(data)
return '200'
if __name__ == '__main__':
app.run(debug=True)
1.命令行输入,运行register.py
文件:
>>> python register.py
2.在浏览器里打开register.html
,输入用户名和密码:
点击提交你会在页面看到返回
200
,命令窗口会输出前端传来用户名和密码:关于json模块与flask jsonify拓展包使用请参考:
