Python使用Flask框架获取当前查询参数的方法

from flask import Flask,render_template,request
# Initialize the Flask application
app = Flask(__name__)
# This is a catch all route,to catch any request the user does
@app.route('/')
def index():
 qs = request.query_string
 return render_template('index.html',query_string=qs)
if __name__ == '__main__':
  app.run(
    host="0.0.0.0",port=int("80"),)
