将数组从Python返回到Javascript

import json

json_array = json.dumps(my_array)

var json_array = '[1, 2, 3, 4, 5]';
var my_array = JSON.parse(json_array);

from flask import Flask, jsonify

app = Flask(__name__)

@app.route('/get_array', methods=['GET'])
def get_array():
    my_array = [1, 2, 3, 4, 5]
    return jsonify(my_array)

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

$.ajax({
    url: '/get_array',
    type: 'GET',
    success: function(response) {
        var my_array = response;
        // 处理返回的数组
    }
});
