如何从Pymongo执行JS脚本文件？

from pymongo import MongoClient

client = MongoClient('mongodb://localhost:27017/')
db = client['mydatabase']
collection = db['mycollection']

js_code = "function add(a, b) { return a + b; }"
result = collection.find_one({"name": "John"}, {"script": js_code})

print(result)

from pymongo import MongoClient
import bson

client = MongoClient('mongodb://localhost:27017/')
db = client['mydatabase']
collection = db['mycollection']

js_code = "function add(a, b) { return a + b; }"
result = collection.find_one({"name": "John"}, {"script": bson.Binary(js_code.encode('utf-8'))})

print(result)
