如何解析用户输入的参数？Python

import sys

def main():
    if len(sys.argv) > 1:
        print(f"参数列表: {sys.argv[1:]}")
    else:
        print("没有提供参数")

if __name__ == "__main__":
    main()

from flask import Flask, request

app = Flask(__name__)

@app.route('/submit', methods=['POST'])
def submit():
    param1 = request.form.get('param1')
    param2 = request.form.get('param2')
    return f"参数1: {param1}, 参数2: {param2}"

if __name__ == "__main__":
    app.run()

from flask import Flask, request

app = Flask(__name__)

@app.route('/api', methods=['GET'])
def api():
    param1 = request.args.get('param1')
    param2 = request.args.get('param2')
    return f"参数1: {param1}, 参数2: {param2}"

if __name__ == "__main__":
    app.run()

import json

data = '{"param1": "value1", "param2": "value2"}'
parsed_data = json.loads(data)
print(f"参数1: {parsed_data['param1']}, 参数2: {parsed_data['param2']}")

import os

param1 = os.getenv('PARAM1')
param2 = os.getenv('PARAM2')
print(f"参数1: {param1}, 参数2: {param2}")
