从控制器函数获取特定值

from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/user/<username>', methods=['GET'])
def get_user(username):
    # 从URL参数中获取用户名
    user = username
    return jsonify({'user': user})

@app.route('/search', methods=['GET'])
def search():
    # 从查询字符串参数中获取搜索关键词
    keyword = request.args.get('keyword')
    return jsonify({'keyword': keyword})

@app.route('/submit', methods=['POST'])
def submit():
    # 从请求体中获取数据
    data = request.get_json()
    name = data.get('name')
    return jsonify({'name': name})

if __name__ == '__main__':
    app.run(debug=True)

@app.route('/user/<username>', methods=['GET'])

    return jsonify({'user': username})

@app.route('/search', methods=['GET'])
