创建一个首先发送串行对象的程序：

import flask
import pickle
object_to_send = {1:2}
@app.route('/endpoint')
def endpoint():
return pickle.dumps(object_to_send).hex()
app.run(port=8080)

然后你可以从另一个python程序调用它，并读取该对象：

import pickle
import requests
object_hex = requests.get('http://127.0.0.1:8080/endpoint').text
object_received = pickle.loads(bytearray.fromhex(object_hex))
print(object_received)

这绝对不是一个最佳实践——如果可能的话，也许你应该串行化为json，或者使用一些消息传递框架，它应该支持不同的串行化方法，或者像Kafka这样的消息总线。
