Python：在Flas上处理多个请求

Question

我在Python上创建了一个简单的webservice应用程序，它公开了另一个类中的一些Python函数。当我向localhost发起一个请求时，它连接到API，公开的函数按它的预期执行，但是任何后续的请求都会导致错误。在

这是我的代码：

网络服务.py

#!flask/bin/python

from flask import Flask
from flask import request
import sys
sys.path.append('/src/')
from encrypto import Encrypto

app = Flask(__name__)

@app.route('/call/<function_name>/<arg>', methods=['GET'])

def callFunction(function_name: str, arg: str):
    functionToCall = getattr(Encrypto(), function_name)
    return str(functionToCall(arg))

if __name__ == '__main__':
    app.run(host='localhost', threaded=True)

以下是我运行的演示：

^{pr2}$

它会导致以下错误：

Error HTTPSConnectionPool(host='localhost', port=5000): Max retries exceeded with url: /call/encrypt/oranges (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'SSL23_GET_SERVER_HELLO', 'unknown protocol')],)",),)): Could not access this url: https://localhost:5000/call/encrypt/oranges

 Error HTTPSConnectionPool(host='localhost', port=5000): Max retries exceeded with url: /call/decrypt/apples (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'SSL23_GET_SERVER_HELLO', 'unknown protocol')],)",),)): Could not access this url: https://localhost:5000/call/decrypt/apples
[('http://localhost:5000/call/encrypt/blahblah', b'1011989968'), ('https://localhost:5000/call/encrypt/oranges', ''), ('https://localhost:5000/call/decrypt/apples', '')]

从上面的输出中可以看到，后面的两个API调用返回一个空字符串，表示错误。在
